Title: 2019 Sony 4K Projector Owners Thread
Post by: Dylan Seeger on February 11, 2019, 06:23:40 PM
Sony US sent me a Sony VPL-VW695ES. I've recently been recruited by hometheaterreview.com to write reviews for them. So while I technically don't own this unit, I thought we should open a separate thread for those who own or are thinking about buying a 2019 Sony 4K model. My review of the 695ES will be posted there eventually and I will link to it here.


Sony sent it to me in this custom road case.  8) Unfortunately, like with the arrival of my JVC DLA-RS2000, I'm stuck at work for the evening and won't be able to look closely at this unit in my dedicated theater until later.

I was able to quickly throw an image up on the wall at work and I noticed right away something different. I can't 100% confirm until later when I have it in my dedicated theater, but it seems (on this unit anyways) the issue with posterization has either been dramatically reduced or eliminated completely. If this is true, I will finally shut up about this issue. I'm sure people are sick and tired of it. Things are looking positive though.

Regarding banding/posterization issues. I can confirm, now that I've had a look on a proper screen, that it's mostly gone. I'm talking 95/100 performance now. Seeing how I only have this one unit to base this off of I can't say for sure if my unit is an outlier or if this is common performance among the entire 2019 line up. However, this is only with a UHD signal being sent to the 695ES. Sending 1080p shows a ton of banding still.

Just mounted a new 270 / 295 on my 110" scren this aftenoon, and been playing with some mixed content after a fast calibration.The projector is ok, and image much cleaner than previous Sony projectors i have seen, but with a CRT projector hanging the black level of this thing is horrible, measured a fast 6500:1 on off contrast,the black level is around my usual 5% ire level, it makes dark scenes in Blade Runner 2049 compleetly washed out. and its not bright enough to make HDR content pop.


Lens is not amasing, ok ish ill say, and motion is fairly bad comming from CRT, but compared to other digitals i guess its ok. 180P upscaling is far from impressive, seen edge ringing, wich should not be there, will have to trow up some testpatterns of various kinds later.


Thats my first impression, unless there is a magic button on this projector i have missed i doubt it will see much action in my HT in the future.
Title: Re: 2019 Sony 4K Projector Owners Thread
Post by: Dylan Seeger on February 14, 2019, 06:29:25 PM
My suggestion would be to have Reality Creation enabled, but have the resolution and noise filtering settings set to 0. This should remove any ringing that you're seeing.

If you want excellent motion, you're going to need to move to a DLP projector. With 24p content, the response time of the DLP mirrors is fast enough to fully resolve the amount of motion resolution that 24p can capture. But you're not going to get the type of contrast performance that Sony and JVC are capable of. I'm actually surprised you went with a Sony instead of a JVC considering you're used to CRT levels of black.

I have everything turned off, and indput lag reduction on.


Been fiddeling a bit more, was using the OPPO 203 and a Apple TV4 4K wich was a total disaster of hdmi handshake issues and HDR hickups.


So turned to the OPPO 103D and uses its upscaling, wich i find better than the 203, shifted the convergence alignment a bit, not the zones just the center adjustment, wich lined it up nicely all around, not sure whats enhanced HDMI, Sony is not clear about that in the manual, so set it to Normal, and will say i now have a very nice image.


Ill say its not a 4K HDR capable projector, it will display it sure, but i prefer the HD Blu Ray upscaled, will give the Panasonic tonemapping a go at some point see if it can save the day, but ill think its simply not bright enough to make for a good HDR presentation, as it needs to much tonemapping/ convertion.


It will most likely be sold again after a while, its just to make some updated A/B comparison to the CRT, last Digital was the Sony 40ES wich was god awfull, and before that the JVC RS50, wich in many ways was ok, except extreme gamma drift, short lived lamps reversed capasitor on the IR board and at 1400 hours a dead balaster.. So never realy forgave JVC for making that piece of junk, and beeing to arogant to call them back and correct the hickups.


I would not mind to get my hands on the JVC RS2000 for a test spin at some point, except im not really willing to flush that kind of money down the drain again, so will most likely wait for the replacement in a few years and see how these new models keep going.


There is alwas someone who will buy a Sony with a few hundred hours on it for ½ of new price.
Title: Re: 2019 Sony 4K Projector Owners Thread
Post by: Dylan Seeger on February 14, 2019, 07:56:14 PM
Going from an RS50 to a new RS2000 will be a HUGE jump in overall image quality. So much has improved since then. The 695ES I currently have for review is a big step up from the bottom end 295ES model as well. More contrast and more lumens. It throws a very nice image. If it weren't for JVC, I'd own the 695ES. Sony has pretty much fixed the biggest issue I used to have with their 4K models which I discussed above. It's either this or Sony cherry picked this unit to send to reviewers.
Title: Re: 2019 Sony 4K Projector Owners Thread
Post by: stridsvognen on February 14, 2019, 08:50:31 PM
I see there is still no way of getting rid of the distortion to the luma test patterns, and its very sensitive to contrast adjustment, guess thats SONYs touch to the image wich they will never let go, its not as bad as earlier SONY projectors i have seen, but it will not do a 1:1 pixel resolution without some color graduation issues.


As i have it setup now the main issue is black level, a manual iris would have been nice, the way contrast adjust the light output, and not the white clipping and i calibrated it at a 70 setting it would be possible to put contrast to 100 and close a iris down to get the same light output, and lower black level a bit, but i doubt it would make much of a improvement, the native contrast is simply a joke.
And guess a good DLP would fo just as good or better.


Brighter images looks nice and fairly clean, not to much banding or artifacts, i still not put it true the low level banding torture test, but it seems to hold up fairly ok so far, looking the gray ramp that also seems to be depending on contrast setting, so im sure you can find some setting where you have horrible banding at at some level, so give the gray ramp a shot to see where it freaks out.

Go into the service menu and turn item 21 off. Wil help turning off the auto zone alignment.
Title: Re: 2019 Sony 4K Projector Owners Thread
Post by: Dylan Seeger on February 15, 2019, 01:18:05 AM
As Mike mentioned if you go into the service menu there is a setting you can disable that should remove most of the artifacts you're seeing. The pink and green banding is caused by the factory set zone convergence correction software. I posted detailed instructions on how to disable it here:

https://discuss.avscience.com/index.php?topic=1369.msg6348#msg6348 (https://discuss.avscience.com/index.php?topic=1369.msg6348#msg6348)


If you want a more fully featured projector (with iris control, better contrast, more lumens, ect) you'll need to step up to the 695ES. As I mentioned before, though, coming from a CRT you might have better luck with a JVC projector (even an eshift model) as that will have a dramatically darker black level like you're used to.
Title: Re: 2019 Sony 4K Projector Owners Thread
Post by: stridsvognen on February 15, 2019, 03:41:05 AM
Thanks, ill try turn that off, makes sense that its a zone convergence issue. might also fix the uniformity issue that i seen on a full white.


Im surprised how transparent it is, and sensible to source devices, and got it to look quite a lot more natural than the ones i seen on demos.


Have a feeling it will go well with the Xbox One

Title: Re: 2019 Sony 4K Projector Owners Thread
Post by: stridsvognen on February 15, 2019, 04:17:22 AM
Did the service menu correction, sadly it changed nothing, it looks the same, so if its a convergence thing they change the way that works in this model.
Title: Re: 2019 Sony 4K Projector Owners Thread
Post by: stridsvognen on February 16, 2019, 07:45:04 PM
I checked today, the zone convergence still works, even its set off in the service menu.
Is there any extra grayscale controle in the service menu somewhere, a 11 point grayscale adjustment would be sweet.


I doubt there is any way of getting the sony panels to resolve 1:1 it got the typical color shift, and its changing with contrast, from what i have been reading the 4K JVC have that under controle.
Title: Re: 2019 Sony 4K Projector Owners Thread
Post by: Dylan Seeger on February 16, 2019, 07:53:53 PM
I know this sounds obvious, but you've disabled the zone convergence correction in the regular menu as well, correct? Even with both off, there will still be some color banding and posterization issues. I don't think this can be completely eliminated unless Sony does a complete overhaul to the hardware. I hope to see this next year. Their model number naming scheme indicates this might happen next year. Where do they go from the 295 and 695?
Title: Re: 2019 Sony 4K Projector Owners Thread
Post by: stridsvognen on February 16, 2019, 08:13:05 PM
Yes i have the zone convergence turned on both places. On the bright side this projector seems to resolve 1080P very well, the SONY 1080P projector never did that...  And im actually enjoying the projector after getting it calibrated and setup to my liking.


Running HD BD upscaled to UHD from a XBOX ONE S wich is the best player for that job i have, gives a very nice and natural looking image, no artifacts or ringing, the hole HDR thing really dont sit well with me, gave it a shot with the Panasonic player today, tweaking the tonemapping, but i simply far prefer the HD SDR masterings at a 12-14fl on my screen.


The focus seems to drift quite a bit, think i adjusted it 5-6 times now with 20 hours on the projector.

Here is what I'm seeing with the 695ES disabling the zone convergence correction software. I'm still unsure why your unit isn't responding the same way. I took these a couple days ago:

Agreed, I think in 2020 Sony is going to have to offer something more similar in price and performance to JVC 4K.  Sony has not given many reasons why one should pay more for the 695 over an RS1000...let alone RS2000.

Dylan, when do you anticipate being able to provide some information on comparing the Sony 695ES with the JVC RS2000?  This is assuming you have both in your possession, and of course I may be mistaken.


Thanks.

Yes, both units are here. I'm currently working on reviews for each projector so a long comparative write up is going to have to wait. In the mean time, is there something specific you want to know?

When you get the opportunity, post pictures of the test pattern I sent you. It should remove a lot of the banding and chroma issues. But as I mentioned before, I think there are hardware limitations with Sony's current 4K SXRD platform. Hopefully they are working on a revised 4K SXRD panel and related supplemental hardware to process and feed them data.

Yeah - which one is better?? ;D ??? :P


But seriously, I am wanting to upgrade my RS400, to get more light, detail, better color, contrast, etc., on my large 160" diagonal 2.35:1 screen.  My plan was to get the RS2000 with the Paladin DCR lens (providing a better 'bang for the buck,' and theoretically 20% more light output), rather than getting the RS3000.


It has now been determined that while the DCR lens works perfectly with the RS1000/2000/3000 series projectors for scope content, it doesn't have the proper Anamorphic modes for 16:9, nor for 3d in either aspect ratio.  There are work-arounds, each with their own advantages and disadvantages, but there are compromises to be made.


And further, the latest information is that JVC does not have plans to address these limitations in this generation of projectors.


In exploring all my options, I wondered about other projector brands.  It is my understanding at this point that the Sony 695ES *does* have the proper Anamorphic modes to use with the DCR lens, for all available content, so would solve those problems.


So basically, if I knew that the overall picture quality of the Sony matched or exceeded that of the JVC, then that would be very tempting.


But on the other hand, if the JVC provided a clearly better overall picture, then I would either deal with the limitations and work-arounds or just wait for the next generation of JVC projectors that would 'hopefully' address these limitations.


So I guess I'm just looking for the 'real-world' 'big-picture' comparison to help me decide here, rather than the nitty-gritty of a formal review, with all of the technical details, which while important, are not always directly related to what kind of overall visual experience is provided.

Post by: stridsvognen on February 17, 2019, 04:07:41 PM
Got it as good as it gets i think.
The convergence shift is also messing up the 1:1 resolution, so it needs to be turned of as well, now everything looks sharper and less distorted, have a bit of convergence error, but only visible when moving closer to the screen.

The answer depends on the type of content you normally watch. If you're mostly watching movies, I'd pick the JVC. The Sony, in my opinion, is better suited for those who game or for those who watch a lot of sports. I say this because the Sony has lower input lag for gamers by about 15ms and people who watch a lot of sports can benefit from the Sony's slightly better motion handling with higher frame rate content (60p for instance). I also think that Sony has better motion interpolation software which a lot of people who watch sports enable. Sports and video game content is generally higher in APL (brighter overall) which is where the Sony's higher ANSI contrast performance will help as well.

However, I think the JVC's far better native contrast, combined with a slightly better lens, better color performance (with the P3 filter), more extensive HDR controls and overall lack of image artifacts (slight banding and posterization still on the Sony) yield a better experience overall for UHD blu-ray and 1080p blu-ray content.

This is going to be the gist of my comparison review but I plan on going into quite a bit more detail with measurements and other objective information. But, overall, both of these projectors offer excellent image quality and I don't think anyone would be unhappy living with either. It's just one of those things where you need to know the type of content you plan on watching the most and choose based on that information.

That is an extremely helpful reply, Dylan.  I would say 98%+ of what I watch is movies, with 0 gaming, and sports only rarely (we'll watch Premiere League Soccer on my Sony 900E TV in the other room).


I have also been paying close attention to Manni's reports concerning use of the filter, which seems to have been confirmed by 1 or 2 others, that there is only 10% or so light loss with use of the filter when in High Lamp mode.  With my larger screen, I'd most likely be in High Lamp mode anyway, so that might be a worthwhile tradeoff.


I'll look forward to your more detailed observations when they're available, but this is exactly the kind of information I need at this time.


Thanks again!!

Just get a standard Paladin instead of the DCR. You get all the features you want plus the bump in light. You're only losing the 6% or so of light by not going full 4096, but most never use 4096 even without the lens. Less scaling, all the features you want. This should be a no brainer.

Hey Kris,

Thanks for the reply.  The standard Paladin is certainly a viable alternative, as you point out.  Because of the minimum throw distance of 1.6x screen width (vs 1.4x with the DCR), I would have to move my mount back about 2 feet or so, and replace my HDMI cable with a longer one.  A bit of a hassle, but do-able.

I also confirmed with Shawn Kelly that if you do use the 'Zoom' Aspect Ratio option, you can still get the full 38% bump in light, and the cost being a 2.5% crop of the image top and bottom.  This would scale, and thus lose 1:1 pixel mapping, but I haven't yet seen any evidence that this is problematic with real-world content.  It might be, but I just haven't read it thus far.

Appreciate your again pointing out this option.

I have around 60 hours on the sony now, ordered some different sunglases for the 1 eyed, and hopfully ill get time to play with it this weekend and do a final calibration.
Ill post some calibration images when im done.
Title: Re: 2019 Sony 4K Projector Owners Thread
Post by: stridsvognen on March 07, 2019, 04:35:27 PM
Got the filters to play with, and now have a calibration at 12fl with a ND 2 filter in front of the lens, who boosts on off measured on screen to 7900:1.
However there is now a new issue, with contrast now up at 93, vs 67 without the filter i now get quite heavy color banding/ purple bands in clouds and other bright areas, that is far less agressive with the low contrast setting.

I have been true all settings and there is nothing i could find that would change that behavior.

Its a 4K projector yes, but not realy capable of resolving a 1080P 24fps 8 bit image without quite heavy distortion, so i think ill revert back to my low contrast setting, and remove the filter.

Calibrated the VPL VW270ES (295) today using the SONY Image Director 3 software, and got a straight 2,3 gamma.

The Sony ansi contrast performance makes for a unike image that all the JVC projectors lacks, sadly the SONY have other shortcommings.

The Sony seems to be panel/ driver issues, the JVC seems to be lens related/ optical issues, i would love to try put a sony lens on a JVC projector, it looks like all the JVC have some serious issues building a lens with good antireflective properties, where the sony seems close to perfect, ill expect quite a bit of the ANSI contrast performance on the JVC is lost in the lens, its to be honest very bad on JVC, very very close to CRT, to the point you cant actually see the difference.
My next mission will be to find a defective SONY 4K projector to grab the lens from.

The test JVC is ready.

The Sony seems to be panel/ driver issues, the JVC seems to be lens related/ optical issues, i would love to try put a sony lens on a JVC projector, it looks like all the JVC have some serious issues building a lens with good antireflective properties, where the sony seems close to perfect, ill expect quite a bit of the ANSI contrast performance on the JVC is lost in the lens, its to be honest very bad on JVC, very very close to CRT, to the point you cant actually see the difference.
My next mission will be to find a defective SONY 4K projector to grab the lens from.

The test JVC is ready.
Have you actually compared the sharpness of the 295 and 695 vs the RS1000 and RS2000? Everyone that I know that has made the comparison has said the JVC is sharper. By eye, you think you can tell a difference in ANSI between the 295 and the RS1000?

I don't think you can attribute much of the ANSI differences between the Sony and JVC to the lens. Heck the HW series of projectors all have higher ANSI than the JVC's and those lenes are crap. The HW series has higher ANSI than the RS4500 and RS3000. Only a fool would pick the HW lens over the 3000/4500 lens.

It's actually hard to compare them. The pixel fill on the JVCs is so much higher than the Sony 4Ks. When I first powered up my RS2000 I thought the lens couldn't focus properly because I could barely see any pixel grid. Because of this people may think the JVCs look softer, so I think subjectively many might prefer the Sony with its more pronounced pixel grid. But when you pull up test patterns you can see the JVC clearly wins. It looks perfect. The Sony 4Ks have problems with single pixel patterns.

This is not about sharpness, its about reflections, light streaking, look at a JVC with the OPPO screen saver, it looks absolutely terrible, the vertical streaking, the reflection that lights up the screen in other places, the 295 dont suffer that, so im curious if its the lens or the light engine.Antireflective coating might make the optics less transparent, but as lightoutput and sharpness is not a issue i worry about on any of the 4K projectors, its surficiant on all of them for my need.
I clearly see the difference from a JVC with a 130:1 ansi contrast, to the sony with 350:1, its just much more clean contrasty look on all scenes, even fairly dark ones.

I did a experiment with different ND filters on the 295, and it generated a similar issue the JVC optics suffer from.

If i get a SONY lens and if its possible to mount it on a JVC it would be interesting to see the ansi contrast differences, ill also try work on those reflective surfaces in the lamp engine, and the JVC lamp asembly see if that makes a difference.

If im to replace my CRT with  500.000:1 on off contrast and 100:1 ansi contrast, i need something that lifts the ansi contrast significantly above JVC level, and the SONY do that, but the on off is so god awfull on the SONY that its a joke, + the banding issues can be fairly anoying, i adore its stable solid image and high ansi contrast, and to be fair the on off contrast might only be relevant in 3% of all content, but when it is, its far more obvious.
If ansi dont matter i already have the best projector, i just think both on off and ansi contrast is important, and i would be satisfied with 100.000:1 on off with 14fl on scren and 400-500:1 ansi, black bars will be significantly darker, colors cleaner, and highlights not washing out lower level details.

I know, but as my ultimate reference is a CRT i dont have the artificial digital sharpness fetish, and i apriciate 4K more smooth and soft edges. Also why ill never use the Panasonic player on my projector setup, the sharpness ringing looks horrible in my eyes, but im well aware that lots of people prefer that look.
 And as i said before the SONY suffers from bad panel/ drive issues, and the JVC from optical streaking and flaring, so if it would be possible to combine the 2 and get the best of the SONY and the best of the JVC it would be a very nice combination.

A 1080p JVC that only measures 130:1 in ANSI has something major wrong with it. I have had many 1080p JVC and my last in the 400 series was a 420 and it measured around 250:1 in my batcave. My Cineversum BW2 measures around 300:1 if I dont remember wrong and I dont have the numbers on this computer. 

And I have done many side by sides with Sonys measuring up to 550:1 (VW1100) and it is very difficult to find movie material where you can see a difference accordig to the ANSI difference as ANSI is a non important number when it comes to movies. Doing a side by side with the same JVCs and Sonys shows a clear difference in the dark to very dark material due to the major difference in on/off contrast.

Might be a problem with your equipment then, i know my meter measures a bit lower than some others, but not that much, and in the same setup conditions its fairly good guide of the difference.
Didrik got around the same results as i did, its as simple as displaying the ansi testpattern on screen, if its not obviously better on the sony ill say you have some issues in your room. 
If you really apriciate the JVC ansi contrast and dont see the difference, you should try a good CRT, it will blow your ming with 5 times better on off contrast than you have ever seen before.

I am not going into a CRT discussion with you ever again. :D

The reason it is difficult to see the difference when it comes to ANSIcontrast is that it is a pattern and it is not very relevant when it comes to video material. And most rooms can not show more than 200-300:1 at the screen, not even a batcave. That is the reason I cant see much of a difference in bright material when side by side testing Sonys and JVCs.

There is not anything wrong with my equipment, but when a JVC X5900 only mesures 130:1 ANSI there is something wrong with the unit and it is not close to how a JVC in that range should measure.

ANSI is a 50% APL pattern and most movies we watch has a APL of around 10%, even The Art Of Flight has an average of 30% and it is mostly filmed outside in the snow.8)

And my Cineversum has an on/off at around 700000:1.:)

Yeah with a dynamic iris, but that dont really work in dark scenes as it compleetly messes up your gamma performance out of black, your lucky if you have 70000:1 with auto iris turned off, im talking about true contrast not manipulated gimick contrast.True the JVC most likely measure around 150:1 using the Klein K10A but again the SONY also measure higher.
What you could do is setup your meter shoot a picture of the setup conditions and the measurements and post it here, only takes 10 min to do.

I do also remember your contrast measurements on the norwegian forum where Gorm had to correct your calculations so im fairly sceptical about your measurements, you seem to be on your own here, if i recall it was actually around 30000:1

Most of Oblivion shows quite well the superior ANSI from the SONY, even in low level scenes, and good ansi also help low level scenes remain more well defined as they elevate as it will push up the point where the bright elements effects the dark areas. Ansi works at any APL, you can try measure a 10% window on your rebadged JVC with a average image surrounding the measuring pattern, and see how it effects all your readings, HCFR have a feature like that, quite interesting. And here ANSI contrast plays a big role keeping the surrounding not poluting the testpattern. Very relevant to how movie content works out.
With CRT i measure around 100:1 ansi contrast, and all the JVC projectors are very identical except a X30 that measured 80:1 the rest is around 130:1 with my equipment, my meter is not optimal for ANSI as it most likely shoots a bit to wide cone, but its consistant, and ill think as good as your meter or maybe even better.

However ill have to take your word for it when you say you cant see the difference as its your eyes, and we all knows some see better or worse than others. Ill still apriciate the benefits of sonys high Ansi contrast, and lack of streaking and spot reflections, to the point ill like to see if i can mount a sony lens on a JVC and see if the issue is the lens itself or in the light engine.

Post by: Andreas21 on August 12, 2019, 03:08:13 PM
ANSI is a testpattern with 50% APL and that is only what it is.

What you are talking about is intrascene contrast and then the JVC that is not fautly better than any Sony from 15% ADL and down. So your JVC is not a perfect unit.

I know what I am doing and I have actually learned Didrik how to do it and you seem to trust him.8)

My Cineversum measures over 120000:1 in the iris postition I use and the gamma modulation works perfect and you can not see it working with the DI on and it is not very measurable. With your equipment you can just dream about measuring anything under 10% anyway. ;D

You own the worst of the JVC models and I own one of the best and I have done side by sides with 400 and 5/600 series and it is a no contest when it comes to dark material.

The time Gorm corrected a measurement you have to know the hole story, because when you measure contrast on a JVC facing the screen sometimes you get wrong readings and that is what happened in one of the screenshots I posted. To get perfect readings you have to measure facing the lens and I alway do that to check the readings from the screen. I measure at least 10 times from the screen to see and verify when measuring facing the lens. So I think you have no idea what you are accusing me of. 8)

My 3000 does not have the streaking with Oppo screen saver.My RS4500 had next to none and the same with my RS640. 130:1 ANSI on a JVC sounds like a defective JVC. In the darker scenes, the native is the controlling factor, not ANSI. In the brighter scenes, the brightness in the image dilates the pupils, So the black appears darker. That is why you can't tell a difference in lower ANSI contrast.

Kris Deering and others have done side by side tests, using a DLP (Samsung 900) with around 1,000:1 ANSI vs a 1080P JVC with around 230:1 ANSI. Everyone there was hard pressed to be able to tell any difference in the brighter scenes, but you could easily tell in the dark scenes, how much better the JVC was. As I said, your eyes are biased, by the brighter scenes and it made the darker areas of the image appear darker, so it was hard to tell a difference between the two projectors. These were controlled conditions with brightness matched and calibrated projectors.

Sorry, but this made me laugh. If you are seeing a significant difference, as in the Sony looks better, then the JVC was not set up properly. This is assuming you are looking at comparable models, like VW695 vs RS2000. There have been many shootouts performed side by side and most people picked the JVC as the overall best projector.

A lot of this falls into the realm where the measurements don't always translate to how the human eye perceives things. When you factor in the fact that the majority of Hollywood content falls under the APL range where ANSI contrast actually matters, it goes to show you why most people still prefer the higher on/off of the JVCs. I'm not saying you aren't seeing the difference you say you are, but I've never seen a "large" difference in perceived contrast in brighter scenes when doing A/B comparisons between a Sony 4K and a recent JVC projector, both eshift and native 4K. 

I've also seen 4 different RS2000's now and all of them have a huge reduction in internal reflections. With actual content, I'm not seeing the same tell-tale signs where a small bright part of an image reflects to another part of the screen during a particularly dark scene. Streaking has also been greatly reduced on all 4 of the RS2000s I've seen. ANSI contrast is still pretty low, but I've learned that this is the least meaningful measurement that I normally take. 

I don't think you'll get a Sony lens to work. Instead, I would look into a Mitsubishi HC5 or HC9000. I think the lens is manufactured from the same company that JVC uses. The housing and lens in general, looked nearly identical when I had the top off the HC-5.

Im not totaly disagreeing that on off is important, but a combination of both would make for a better image overall, small difference maybe, i still apriciate it, Hate most of the rest of what the SONY do.
There is a really good reason why i overall prefer the Marquee 9500 CRT projector wich much higher native contrast than any other home cinema projector available on the market today, it just kills any JVC in low level performance, however i still see how the ansi contrast have a impact on brighter scenes, and well aware of its weak parts.
It would not really make sense to mount a different lens from the same manufacture, so first ill try find a SONY lens see if it can be custum fitted on the JVC, not that it needs to be perfect, just to satisfy my curiosity, and maybe determine the lens quality, as nobody realy know where the different projectors suffers, it can just as welll be in the mirror and optical blocks in the lamp engine the biggest limitations are, sony could for that matter have the best sharpest lenses, and the worse lamp engine, and JVC the opposite, or whatever way around, all people know is the sum of it all in a factory asembled projector without beeing able to pinpoint where the weak point in the optical path is.
Fact is SONY holds significantly better ansi contrast, and JVC significantly better on off contrast, i doubt anyone can dispute that, and it all holds some importance to image quality, if not you should be happy with a 50:1 ansi contrast, my bet is that above 500:1 will be fairly impossible to see, but how cool would it be if it was possible to put a lens on a jvc and get sony ansi contrast, and compare it to a identical stock JVC, i happen to have 2 old JVC X3 units, wich in most regards performs as well as the last generation 1080P models except total lightoutput, and better native panel on off contrast on the old series.

I think its sad that some people feel a personal atatchment to thair equipment and need to defend it, i find it helthy to keep a open mind, experiment, also beyond normal contrast and brightness adjustment, the narow mindet mentality on forums these days are kind of limiting the objective aproach, i own JVC SONY and others, and ill not hold back discussing flaws and qualities of different manufactures just so others can feel better about their boy toys, im in this hobby to enjoy both the visual and tecnical aspects, and only by knowing the shortcommings and flaws can i try to work around them and reach a better compromise.

Then I can assure you there is something major wrong with your JVC either that or you have a golden Sony sample or maybe even both. I have side by side tested many and always use Oblivion when testing and there is almost no visible difference except when it comes to dark scenes.

As you can see in the comments above here there are many others with experience that have seen the same results as me.8)

Edit as you can see in the aded picture Oblivion has an ADL of around 10% with a 2.2 gamma and it will be even lover with a 2.3/2.4 gamma. :)

It would not really make sense to mount a different lens from the same manufacture, so first ill try find a SONY lens see if it can be custum fitted on the JVC, not that it needs to be perfect, just to satisfy my curiosity, and maybe determine the lens quality, as nobody realy know where the different projectors suffers, it can just as welll be in the mirror and optical blocks in the lamp engine the biggest limitations are, sony could for that matter have the best sharpest lenses, and the worse lamp engine, and JVC the opposite, or whatever way around, all people know is the sum of it all in a factory asembled projector without beeing able to pinpoint where the weak point in the optical path is.
Fact is SONY holds significantly better ansi contrast, and JVC significantly better on off contrast, i doubt anyone can dispute that, and it all holds some importance to image quality, if not you should be happy with a 50:1 ansi contrast, my bet is that above 500:1 will be fairly impossible to see, but how cool would it be if it was possible to put a lens on a jvc and get sony ansi contrast, and compare it to a identical stock JVC, i happen to have 2 old JVC X3 units, wich in most regards performs as well as the last generation 1080P models except total lightoutput, and better native panel on off contrast on the old series.

I think its sad that some people feel a personal atatchment to thair equipment and need to defend it, i find it helthy to keep a open mind, experiment, also beyond normal contrast and brightness adjustment, the narow mindet mentality on forums these days are kind of limiting the objective aproach, i own JVC SONY and others, and ill not hold back discussing flaws and qualities of different manufactures just so others can feel better about their boy toys, im in this hobby to enjoy both the visual and tecnical aspects, and only by knowing the shortcommings and flaws can i try to work around them and reach a better compromise.
99% of the rooms out there can't hit 300:1 ANSI. And I bet 99.99% can't hit 400:1 ANSI. Now a lot of rooms can hit above 50:1 ANSI, so yes, you do want more than that. It is just that once you get above 300:1, it makes very little difference.

Are you saying ansi contrast has no relevanse to that experience.?
ANSI is about the same on the 2000 and the 3000 and on those two particular projectors, the native measured about the same. So it was not ANSI and it was not native that made the 3000 look to have higher perceived contrast. Why it was speculated that the 3000 appeared to have better perceived contrast was the higher MTF of the 3000 lens.

Great so ill try call him this week and see if he will do the calibration and confirm your measurements, just need your aproval, and accept ull have to cover the expenses if your measurements are wrong.

How are you measuring now, on screen or out of the lens.? 
Ill say if the JVC measures 300:1 ill prefer about 800:1 before the effect is invisible in a perfectly dark room.
Ill get a light meter for more acurate results and ill gues the CRT then gets closer to 200:1 and hopfully 300:1 on the different JVC and ill guess 750:1 on the SONY.

Then you have a good room that can show the ANSI of a good JVC, and the reson a Sony or DLP with more than 500:1 will not look any better is because your room will take away the advantage. When it comes to on/off the room has no negative effect as long as no ambient light is present. 8)

So it was not ANSI and it was not native that made the 3000 look to have higher perceived contrast. Why it was speculated that the 3000 appeared to have better perceived contrast was the higher MTF of the 3000 lens.
MTF relates to resolution not contrast, so its 2 different image parameters, so i guess contrast have a verry different meaning to you guys than what i understand from that word, im looking contrast in a bigger area of the image not pr pixel.

Maybe you could define your understanding of MTF and contrast so we are sure we are not confusing each other.

Post by: stridsvognen on August 12, 2019, 08:23:06 PM
Then I can assure you there is something major wrong with your JVC either that or you have a golden Sony sample or maybe even both. I have side by side tested many and always use Oblivion when testing and there is almost no visible difference except when it comes to dark scenes.

As you can see in the comments above here there are many others with experience that have seen the same results as me.8)

Edit as you can see in the aded picture Oblivion has an ADL of around 10% with a 2.2 gamma and it will be even lover with a 2.3/2.4 gamma. :)
As this is aparently very subjective, and you seem to think all my 4 JVC projectors are bad samples, do you think its possible im just more critical about image quality than you are and notice stuff you and some others dont.?
And what exactlely do ADL mean? Would it not be more apropriate to make a screenshot of a specifik scene that you think is impossible to detect a ansi contrast difference between sony and jvc on, and we might be able to measure specifik areas of the image and make a movie scene ansi measurement, or see if the camera might be able to pick up and show it in a screenshot, to get the debate more objective.
In general the SONY belongs in the trash can, its not a joy to wach movies on, no sony ever been in my eyes, but i really like 2 things about it, the high ansi contrast and the totaly quiet solid image with no update flicker, even the 2019 models have less processed and destorted image than previous models, the JVC have other issues, just as no projector is perfect, the JVC eshifters are also a huge compromise and the auto iris is like a pain in the eye, eshift adds noise in the image, and 1080P lack some smoothness compared to a real 4K projector or the CRT.
The only reason i have the SONY is to play with it, unfortunate the 270 lens is to big for the experiment, so cant use it for that.

Yes, of course it does. It was speculated that the higher MTF, (sharpness) gave the 3000 higher perceived contrast. Because we know it had nothing to do with ANSI, as you speculated or native contrast, because those two items matched up for those particular projectors.

Kris Deering did the calibration for the shootout you were referring to and Kris also posted his thoughts on why the 3000 appeared to have higher perceived contrast, even though native was pretty much the same. kris is the one that speculated it was the higher MTF and I thought it made sense.

You will be able to get a idea about MTF if you display a 4K SMPTE pattern and look at the 1:1 horizontal and vertical resolution boxes, and ill bet you would even be able to measure the light output in that specifik area as its a ½ light ½ dark pattern and the lower mtf should have higher lightoutput on that pattern, unless the projectors have different panel resolution capabilities.

I just find the term higher persived contrast a bit misleading if the meaning was higher persived resolution, or maybe 1:1 pixel contrast.
So am i right to understand that the RS2000 and RS3000 looked excactley the same contrast wise, looking a dark and bright area of the image, or the way light played out on the overall frame.?

What was the specifik ansi contrast measurements on those 2 JVC projectors, possible to get the full calibration reports.?

You are being very arrogant and wrong in your assumption that I do not know what I am talking about. It is you that does not understand, if you can't follow this. Just like a brighter image can have a perceived sharpness advantage. Same as a projector with a sharply defined pixel structure can look sharper, even if it is being compared to a projector with equal sharpness. All of this is perceived, because actual measurement show it is not sharper or higher contrast.

Added
You would need to talk to Kris, since he calibrated the projectors, or you can go through the thread and read his posts. I know some of the numbers are there. But I recommend you take a different approach (attitude), because always assuming you are right and everybody else is wrong is not going to get you very far.

What is it specifikly you think is arogant? im trying to understand the meaning of specifik terms so we dont misunderstand each other, adds a few ideas to test MTF.

You asked about the calibration reports. I said you would have to get them from kris, if he was willing to send them. I also said Kris had some of the calibration info in his posts in that thread, so you could run it down that way. Also I type one thing and you don't seem to grasp what I am saying. You just go back to what you said before. I said those two particular projectors (RS2000 and RS3000) happened to measure nearly the same for native contrast, but when viewing the RS3000 looked like it had better contrast. ANSI contrast on all three of the new JVC's is about the same also. So since the contrast measures about the same and yet one looks like it has better contrast, then it is perceived contrast. This is all explained in the thread that you brought up. 

Why do I need to measure MTF? Everybody knows the lens in the RS3000 is a much better lens than what is in the RS2000. I just said that Kris speculated the higher MTF of the 3000 lens is probably why the 3000 looked like it had higher contrast. 

You keep talking about seeing a difference in ANSI between two projectors that should have ANSI of 230 vs 450 and yet people like Kris Deering and others have set up two projectors with much higher ANSI differences than what you used and had a hard time telling any difference. This is with them even freeze framing scenes to study them.  Kris has talked about this numerous times. kris also had others there and they agreed with his findings. 

Since I keep having to repeat myself, I am done posting on this.

Ok forget about calibration reports, and forget about sharpness for a moment.

What i understand from MTF is sharpness, but you guys say percived contrast, and when i look at contrast its about  how the light plays out on the specifik scene in general not pr pixle sharpness, so i like to understand what MTF really means in your world, as it seems different from what i understand, to me its 2 different image parameters.

If you dont think about MTF and sharpness and look more roughly on the RS2000 and RS3000 from a longer distance, do the persived contrast between bright and dark areas of a frame look the same, or do you also percive a difference there.?

Here is a few samples of frames to ilustrate what contrast, specifikly ansi contrast is to me, where the sony holds better in the low light parts of the sceen and the JVC visible vashes out the dark area, even that my sony have a slightly lower gamma, 2,3 vs 2,33 on the JVC.

Just because the lens is made by the same manufacturer does not mean its the exact same lens. The Mitsubishi HC9000 (HC5) was able to hit about 450:1 ANSI contrast and uses a lens that would more easily integrate within the JVC projector chassis. I highly doubt you'll be able to fit the Sony lens inside JVC's chassis let alone figure out a way to get the motorized lens controls to work.

Ill keep a open eye, i doubt its a model widely sold here so finding a cheap or defective unit might be extremely hard.
The motorised controles holds no importance for a test setup, ill just put my hands on it and adjust it manually, it is very likely that the ansi limitation is in the lamp engine/ mirrors and housing, so might be even more fun to try open up the light engine and look how JVC aproched light reflection controle there, and potentially do the same on a SONY unit.
The lens must be at least 55mm long backwards from the mount plate, and diameter no bigger than the JVC if i can find something like that its just build a adaptor or spacer of some kind to mount the lens.

I was not there at that shootout, so I can't comment on if there was a difference, with increased distance. As I said, Kris speculated that it was the MTF, since it could not be ANSI nor a difference in native contrast. Also could see the difference with dynamic iris off on both. Perceived, just like a speaker comparison can fool people if one is played louder. One poster said he used to sell audio gear. Said when comparing speaker A to speaker B, sometimes he would switch from A back to A, but increase the volume a little. Everybody always commented on the louder speaker as being much better. So this is a perceived difference, because there is no actual difference. Same with the contrast we are talking about.

So this is a perceived difference, because there is no actual difference. Same with the contrast we are talking about.
Small gamma changes, grayscale tracking differences, and as seen on the calibrations posted they were a bit rough in the low end could very well make for a percived difference, also processing can change percived MTF/ pr pixel contrast, thats what Darbee do, and the JVC N series might have some sharpness addet by defoult, maybe more on the NX9/ RS3000 than the other ones, what i wonder is that i have heard from others that the RS3000 actually have higher ansi contrast than the RS2000, + it has a bit of extra optical sharpness.
Ill bet you that i could setup a demo like that and make everybody pick the RS2000 without anyone noticing what i did, and the article also only publish a fraction of the calibration data, actually the part thats least interesting, or tells verry little about the performance, a 1-2-3-4-5% IRE out of black gamma measurement and overall 21 point gamma tracking + the actual ansi contrast measurement would be far more interesting. You might even find people who uses a Panasonic player on a JVC 4K projector and prefer the effect of the backdoor processing/ sharpness and edge ringing in the image without beeing able to pinpoint it. And if MTF was in question im surprised they did not check the MTF instead of just speculate about it.

Here is something no Sony and no JVC can do and as it runs a fairly high gamma it will in many cases look more contrasty and dynamic, and just as a note that was measured with around 12fl so calculate the black level on screen.  From this overheated discussion where most agree that ansi dont hold much importance ill guess we can all agree that the CRT must be the best projector in the world ;-) And that both SONY and JVC still only manufacture gray plastic toy projectors.8)

Of course any calibrator could adjust two projectors and select material to favor one projector, but that was not the goal here. If doing that, you would not provide any calibration reports as was done here. If you knew anything about Kris, you would know that he turns off all processing. Maybe it is the language barrier, but you seem to come across as condescending or accusing, like something was not on the up and up with that shootout. Kris does not sell projectors. While the guy that hosted the shootout does sell projectors, here in the US, Sony has higher profit than JVC, so it would not make sense to slant a shootout to a product that you made less money on. Heck the host of the shootout is my compitition and yet I am defending him. I certainly have no reason, hidden agenda to do so. Time to move on from this.

Matched lightoutput at 15fl on screen.
I spoke a little with Didrik as he is one of my best friends and he tells me you use the contrast slider to drop the lightoutput on your JVC, is this true? If it is it is not strange you see what you see as you have killed the projector in doing this, and if it is true you just show your ignorance. 

I am ok with you thinking and meaning your CRT is the best projector in the world and I also think you have a very personal connection to your CRTs. But to 99.9% of people interested in projection it is a thing of the past. I am sure it shows very dark scenes in a very good way, but not much more than that. And personally I think CRTs is a thing in the past. Enjoy your CRT and try to be a little less insulting, condescending and arrogant in the way you write and you will get a lot more positive comments. :)

Of course any calibrator could adjust two projectors and select material to favor one projector, but that was not the goal here. If doing that, you would not provide any calibration reports as was done here. If you knew anything about Kris, you would know that he turns off all processing. Maybe it is the language barrier, but you seem to come across as condescending or accusing, like something was not on the up and up with that shootout. Kris does not sell projectors. While the guy that hosted the shootout does sell projectors, here in the US, Sony has higher profit than JVC, so it would not make sense to slant a shootout to a product that you made less money on. Heck the host of the shootout is my compitition and yet I am defending him. I certainly have no reason, hidden agenda to do so. Time to move on from this.
A part of the percived difference very likely be calibration tolerances and not unlikely software/ JVC processing wich can be very hard to make out, also why comparing 2 different projectors you will need to be carefull not to mix up to many image parameters and percived or subjective points.Wich is why i prefer some objective tests and results.

That would explain why most of his measurements are so low. I hope he realizes he can't treat these digital projectors the same as his CRTs. Lowering the Contrast setting simply clips everything above a particular digital level to be the same, lower, brightness level. He should be using the manual iris instead.

Now that you pick up and sling around words like ignorance insulting and arogant i guess its a way of alowing me to trow a few stones back, and you might explain how the contrast effects the black level gamma and grayscale tracking, if thats not to complicated for you.?

For the sake of contrast measurements, you can't expect to get accurate measurements if you have the contrast set so low where you're clipping when you shouldn't be. On the JVCs at least, you don't have to sacrifice your contrast setting to get a well tracking gamma or greyscale.

Damn i cant find the iris adjustment on the SONY 270, and the X5900 is at -15
The basic thing the contrast adjustment do is lower lightoutput and make the projector show whiter than white, as long as the gamma still tracks all the way from 0-100% ire there is no loss of information, you can argue that i reduce contrast, as i lower lightoutput and maintain the same black level, anyway its the only way of matching these 2 projectors to a reference level lightoutput, not that i would not prefer a iris or the capability of the iris its simply not a option, and it have absolutely no effect on ansi contrast, and the conclution is the same with both projectors set to 100contrast with 18fl on screen, just that if i wach 18fl for 3 hours ill trow the projector in the bin, poor alcohol on it and set it on fire to never have to use it again.
But your more than welcome to ilustrate what im clipping when everything is calibrated and tracks with a specifik contrast setting, on the JVC currently -7

I know its to dim specially with bad contrast projectors, come over ill show you how 12 fl looks like with a 500.000:1 on off contrast, and later we can crank it up to 16fl and you can see if you prefer that one, not sure you can measure that high on off contrast in a meaningfull way.

Yes, but from a digital standpoint, and how a digital image will be displayed through the projector, you can't lower the contrast setting to clip below level 235 and expect to get accurate contrast measurements. You need to think about these things in a digital way. When taking an on/off or ANSI contrast measurement, the digital level of white in test patterns is 235 so if you're clipping below that, you can't get an accurate measurement because you've artificially lowered how bright level 235 is because you've lowered the contrast setting too much. Does that make sense?

It lowers lightoutput and compresses the bit dept a bit, but can be done gently and preserve all information so that you can match lightoutput to a reference level for comparison on these plastic toy projectors.

Klein K10A profiled to a JETI1501, wich i think was semi defective, we measured multiple scenarios with different brightness settings, that one ilustrated was 300000:1 others as high as 600000:1 and infinite if desired, we just worked on preserving the perfect out of black displaying every level.
We also made a 150000:1 setting wich we tested on various reference low level scenes and agreed that it looked gray like a digital.

If you really want to match the Sony 270 with the JVC in image brightness, buy an ND filter and then use the manual iris if you need to lower the brightness even further. I don't think you fully understand what the Contrast setting does on a digital projector.

You think the Klein was defective when you get different reading from black when black measures 0.000, this also shows you have a lot to learn when it comes to calibration and equipment.:)

It seems you confuse lowering contrast with higher contrast, what i do is a bit the same as the super white function do, or like using a spyder probe for autocalibrating and afterwords having to lower red and loos 2fl compared to a manual calibration, sure im aware that by lowering contrast i lower the digital bit headroom, and has to be carefull with the 90-100% gamma dong start to elevate.
Yes its a compromise, and yes it lowers on off contrast due to the lower lightoutput, but if your eyes hurt running to bright do you prefer not using the projector, or set a comfortable lightoutput beeing carefull you maintain flat gamma and grayscale tracking.?What i see on the X5900 its getting a bit problematic below -7 contrast, so thats where i left it, and can set it back to 0 and it will still track, maybe you could measure and ilustrate what happens on your unit whan adjusting contrast, and what informatin your clipping, and explain how you balance the colors without touching gren and blue gain wich is basically a contrast pr color adjustment.?

You have the JVC in low lamp mode, the iris a -15 and you still have issues with the image hurting your eyes?

The problem is that the contrast measurements you provide aren't valid because you're not setting the projector up like everyone else. You have to measure peak brightness with 235 resolved. Otherwise the measurements you provide are useless to compare to ours.

I have 235 resolved, to clip 235 you need to adjust contrast in the positive direction to clip, your flipping it.

The cell phone clips it a bit but im sure you get the idea what contrast do when adjusted in different directions from the pictures.

The Adeo Plano White has a 10% gain in red in the grayscale and is far from neutral. :)

And you still dont understand how to use the contrast slider on a digital projector. When you use SuperWhite you have to raise the contrast slider to resolve less than 255 and you only mess up the projector. You need to use standard and default values, if you cant get 100% white perfect with the gain control in the projector you migh try to tale away one click on the contrast slider. 7 clicks and the projector image is destroyed. It is as simple as that.

Try to listen to more experienced people and you might learn something.8)

The contrast slider adjustment has been explained to you by two different posters. You use the manual iris to cut the light output. If you still can't get there, you should use an ND filter. Yet you keep asking for an explanation for this when it has been given to you. At some point it just becomes trolling and people are going to stop replying to you.

I have 235 resolved, to clip 235 you need to adjust contrast in the positive direction to clip, your flipping it.

The cell phone clips it a bit but im sure you get the idea what contrast do when adjusted in different directions from the pictures.


I have no idea what test pattern that is. Where does it say that bar is 235? I also have no idea if you're sending full 0-255 or limited 16-235. I also have no idea what other settings you have enabled. All I know is, if your chain is set up properly, you shouldn't need to set the Contrast setting that low. As Andreas points out, generally speaking, you don't need to make adjustments to either Contrast or Brightness to clip and crush at the correct digital levels and if you do generally it's only 1 point off, not 7.

The contrast slider adjustment has been explained to you by two different posters. You use the manual iris to cut the light output. If you still can't get there, you should use an ND filter. Yet you keep asking for an explanation for this when it has been given to you. At some point it just becomes trolling and people are going to stop replying to you.
Then please provide a copy of that reply i failed to see any explanation other than it destroys the digital and your measurements are wrong.
Explain how it works, how it works different than the gain adjustment, what happens with the bit resolution, is it possible to maintain full color and gamma tracking, as ilustrated i have perfect clipping at level 235 at a -7 contrast, the only effect i see is reduced lightoutput wich reduces on off contrast as black level is fixed, and gray filters adds reflections and further optical contrast degradation is that better than loosing a bit of on off contrast.?
I have multiple different high quality ND filters, and done quite a few experiments and will claim that kills the image more than lowering lightoutput a bit using the contrast adjustment.
Im waiting for Dyan to explain how he clips 235 by lowering contrast, if his JVC works oposit mine.

Here is a on screen measurement with 0 contrast 18fl, and a off scren measurement with a -10 contrast, maybe you could show your calibration report from your projector and make a new one with a - contrast setting, and maybe show a clipping pattern and how it reacts and the direct negative consequenses.

Two people have told you not to use the contrast slider adjustment for light output adjustment. Both of them have told you why you should not use this adjustment and that you should use the manual iris. I myself have also posted this and yet you continue. Consider this warning number two to stop or you will be gone.

The iris have no more range, and basically just stating its wrong to do so is not a explanation, and i challenge that, by posting ilustrations and calibrations, yet none of you guys know how to properly document your claims other than it is so, wich ill say if thats the tecnical level here, and threads about banning if i dont agree with you guys with your very limited cababilities to explain yourself, its not that much other than your loss.
So for the sake of documenting your statement please copy past the answers you concider explaining why not to , and how that line up with my documentation, or you need a eye doctor as well? or is that question concidered a personal insult.?;)

all is 16-235 all true the chain normal setup, im telling you its clipping perfect at bar 235, do i need to pull up another pattern to show you.?
Maybe you could adjust your contrast -7 and ilustrate what you see on the clipping pattern as ill guess it will be the same, and still my iris is -15 and 18fl so to match a 15fl for comparisons sake ill need to lower contrast, only visual and measureble difference is that i lower on off contrast by lowering lightoutput and slightly compressing the bit resolution in the projector, exactely like you do when you adjust green and blue gain down to balance your colors.

Ill like to understand why your projector clips 235 when you lower your contrast, thats highly unusual.

A few clicks on the remote and the contrast is back to 0 and its all as you guys like it, so whats the actual problem.?

I have 5 projectors up so sometimes compromises is needet to make proper comparisons with identical lightoutput.

Yes, sorry, I misspoke. But the point I was making still holds true in that you're lowering your light output thus creating an issue trying to take an accurate contrast measurement.

I cannot find in this thread where anybody tried to claim accurate contrast measurements. Can you please provide me a

Speaking of Sony 4K projectors, don't forget that the VW885es has a $5K off instant rebate from Sony. Good until 8 - 31. :)

Contrast measurements were provided. When that happens we assume they're taken with the same set of standards used as everyone else. If that's not the case, why post the measurements? They wouldn't be comparable to everyone else's. So, if they aren't "accurate", why post them in the first place?

Sat. August 31st is the last day to take advantage of Sony's $5000.00 off instant rebate on the VW885es 4K laser projector. Just FYI.

Today Sony sent out an email with an exchange offer.

Sony FPJ Trade in Program 9/30 – 12/29

"A customer can trade in any Barco, BenQ, DPI, Epson, Hisense, JVC, LG, Optoma, Runco, SIM2 or Sony consumer projector and get 10% off the purchase of the Sony projectors on the left."

This applies to:
VW5000
VW995
VW695
VZ1000

Note
• Trade in Projectors must be Consumer/Home Projectors, not professional models.
• Sony reserves the right to end the promotion early with two weeks advanced notice.

I'd be eyeing eBay for a $30 used home theater projector to get that 10% off. Seems like a good deal if you were already considering a Sony projector.

I Used to be an owner of an 885es/ 760es and had issues with 3 of them. Sony was good too exchange them and I only had to add $4K to get a 995es / 870es Unfortunately that had problems as well. Optical block issue. The whole guts of the system. I would have to say Sony had great service and the projectors did throw a great picture unfortunately I just ended up with 4 duds. I ended up with a full refund but still its a damn shame. Apparently the 270es 570es 760es & the 870es have all the same internals bar 760es and 870es. Their difference was Laser and 870es having the lens. With the 760es and 870es with the amount they charge they should of had a much higher end optical block, processor etc. Just under the 5000es.

Sorry to hear about your projector problem. When these things happen it is always a hassle, just to exchange them, but at least you were well taken care of in the end.

Your experience reminds me of mine with the Epson LS10000.  I went through several replacements; all had poor grey uniformity which could not be calibrated out and was very noticeable in content.  I ended up getting a refund from them.  I will say, their customer service was phenomenal.

Thanks Mike,
Sony was great for customer service couldn’t fault them unfortunately their is a time you just have to say enough is enough. 

Hope I don’t have any issues with the NX9

Too be honest I didnt know it was that bad until I watched Schindlers List. I sent the pics to Sony Tech and he said that’s optical Block issue bring it in. I thought it required calibration, boy was I wrong.

My 995ES review went live today. This one is in our "quick review" format, so I don't go as in depth as some of my other reviews, but if you have any questions about performance or functionality not discussed in the review, feel free to ask questions.
