JVC RS4500 (native 4K laser projector)

Or is it possible this is an artifact from the video itself. I didn't look at that pattern with the RS4500. I looked at others though and saw no issues. May have panel alignment on, or not in native for aspect. There are A LOT of settings that can have effects on fine resolution patterns. You just have to start from 0 and see how it goes.

Would be very interesting if someone here could do the tests, and document the results, and maybe include the croma resolution test as well, all at its optimal settings.

The video is to bad to truly show off whats wrong, but the visible color distortion is not a video introduced error, a good way to look at the SMPTE pattern is actually to defocus the camera so the resolution lines is no longer visual on the picture, and see if all 6 squares maintain the same light output and dont show any color shift.

...will there be a 4K JVC light bulb projector that doesn't cost an arm and a leg?...

That's the $ 10,000 question ( see what I did there  :) ) !

Probably - but the better question is what year, or even which decade ?

Craig,
...you know, I can't believe that a company such as JVC would put on the market
a 4K projector that's almost out of financial reach for many.  I would think that
they would realize that, if they want to make a go for 4K, that it should be made
available to a larger purchasing population at a price that doesn't require taking
out a second mortgage.

...but I can't say that I'm unhappy with the e-shift JVC that I have combined with
the OPPO 205...I guess, as you point out, time will tell.

There are only four native 4K projectors available - other than DLP. The Sony VW365 ( $8K - no iris, not so good black levels ), the VW675 ( $15K ), the JVC RS4500 ( $ 35K ) and the Sony VW5000 ( $ 60K ). Sony has a new 4K laser projector coming - maybe $25K, maybe $30K . Digital Projection has some native 4K 3 chip DLP projectors - that run up to $ 150K. Not a lot out there native 4K wise at any price. Add laser and there are even fewer. Frankly, the RS4500 is a bargain compared to the Sim Lumis I used to have ( also $35K ).

Sony has a native 4K laser projector for 60K. While the JVC is not as bright, it seems like a bargain when compared that way.

Just curious: how is the RS4500 a bargain when the price is the same?  Because you're getting 4k for the same price that 1080 costed back then?  In other words, the Lumis was SOTA at the time and the RS4500 is SOTA now. 

Slightly off topic, is there any aspect of performance of the RS4500 that isn't as good as your Lumis was? e.g. ANSI?

Correct - state of the art is a good way to put it. It's a bargain considering the Lumis used $ 950.00 lamps, and laser is much more stable - picture wise and brightness wise.

I'm not sure exactly how ANSI would compare - I'll discuss that with Jeff Meier of Accucal when he's here to calibrate it in a week or so.

I don't find anything lacking compared to the Lumis. In fact, the RS4500 is brighter and has far more flexibility set up wise. And with 4K and HDR, it's another level above the Lumis picture wise too.

Hi everybody :)

I have just put online the first french review about the DLA-Z1 :) Great picture but IMHO not better than the JVC DLA-X9500 under 3 meters widescreen. You might find some pictures comparaison in the review with the Sony VPL-VW550ES, the BenQ W11000 and of course the JVC DLA-X9500.

I just went true the review, and wondered why the screenshots was so full of edge ringing and artifacts?
Its not lack of image resolution on the shots, so is the images processed to look that bad, or is it actually just capturing whats on screen.?

I snapped a few shots of my own projector to compare, from the Blu Ray Oblivion, 1080P on a CRT projector, and even been trying adding massive Darbee (70%) and also some edge and detail enhancement, without beeing able to reproduce the amount of distortion shown on the JVC Z1 screenshots..

Would be interesting if someone else would take a shot at that Oblivion scene from a Z1.

It's hard to see a difference on my computer between those shots, but I see no ringing / edge enhancement on my RS4500 / Z1. Of course the settings on the source device, and any number of things that can happen to screen shot between the camera and you can also effect them. I put no weight into screen shots for that very reason - they are " for entertainment purposes only ". After all, I have a laptop - not a calibrated display here.

Its pretty hard to find a camera that ad as much distortion as is seen on the Z1 screenshots, unless you take a cell phone, normaly you can use screenshots to see artifacts and ringing, no problem, just dont look for color / calibration, its amasing how well a camera picks up the distortion on screen..

But the screenshots in the linked review is sooo bad that its hard to see why they are addet, they are confusing more than helping, They just as well use a SD projector for comparison, as none of the pics are capable of showing high resolution qualities.

Thats why it would be more interesting to see someone else post a decent screenshot, showing off the detail level on a Z1, and prove its not as noisy and distorted as the review make it look like.

Your close up picture on the right looks particularly bad to me - very noisy !
