I have a new JVC 3000 projector and a new Stewarts 100 screen. This replaces my former JVC DLA-RS66U
Boy, am I unhappy with this. The projector is not nearly as bright as the old JVC and you cannot convince me that it is 2,200 lumens. I have tried to lighten the picture but I then I lose vibrancy and brilliance in the colors.
On the old JVC I was very content with the “lower” lamp setting. Here I am using high and it is not as good. We cannot watch a 3D movie on the 3000 because it is so dark you can’t see anything.
And the contrast is poor. Especially a dark or black object on a black background. This was a highlight of JVC, here it is sad. I liked the old projector better!
I am using the Oppo 205 to get a 4k image and the 3D. I also use my verizon to get a regular 1080P picture.
I have played with the settings, is there any suggestions? I must be doing something wrong. When I have changed, for example to THX, The picture color changes poorly.
-
Which older JVC ? Something is not right.
-
66u

Something doesn't sound right. The RS3000 should clearly be brighter than the RS66. What picture mode are you using? For anything non-HDR or 3D place the projector in one of the custom User picture modes. From there select D6500 for the white balance and REC709 as the color profile. Choose a gamma that you like best. Custom gamma with a 2.2 correction value set should look good out of the box.
I'd also recommend disabling CMD and Motion Enhance. Make sure the manual iris is fully open and enable one of the auto iris modes if you'd like. These settings should give a ton of light output.
-
Thanks so much. What settings should I use for 3D?
I called the JVC rep and he said he would get back to me.
-
I haven't played with 3D much with these new models so I'll save that response for someone else.

Something is definitely wrong, if the 3000 is not a lot brighter than your old RS66. Did you set it up or someone else?
-
I think it's also obvious that High lamp mode should be used if you want to gain more light output. If you set the projector up like I've said and it's still not clearly brighter than your RS66, then something is definitely wrong with the RS3000 they sent you. Do you have access to a lux meter? If you can take a brightness measurement at the screen that would be helpful in figuring out if your unit is appropriately bright or not.
-
The same dealer who set up the last one set this up
-
Barry, something doesn't sound right at all. Use the settings that Dylan suggested. I forgot, how big is your screen, 110"?
-
What is your new screen size/gain/throw distance?
You mention that your new screen is a Stewart 100, so I assume nominal gain, but we still need size and throw distance. What was the old screen size/gain and throw distance?
If set to THX (to make things simple, though it might make it a bit dimmer) with high lamp and iris fully open, it should be brighter than the old PJ with the same screen gain/size and throw distance.
If it's significantly dimmer, it could be a dud bulb (that can happen) or a defective unit.
But until you confirm screen size / gain and throw distance for both old and new screen/PJ, it's hard to know as you changed more than just the PJ.
-
I think maybe a better questions is, what screen did you have before? If you've switched from a higher gain screen to the Stewart 100 (a unity gain screen) that right there could account for the appearance of a dimmer image.

Better question than what? That’s exactly what I asked.
-
Ahh I missed the second question the first time I read your post.
-
I have a 110 inch screen, about 14 feet from the projector
-

That's a short throw and a small screen. I can't imagine it not being brighter - ST100 or not.
-
I would have to agree.
-
Have your dealer come back out and look to make sure he didn't miss something during setup. If he didn't and it's still less bright than your RS66, you may want to have your dealer get you a new RS3000.
-

Okay, it shouldn't look dim even with nominal gain. What about the old screen? Size, gain, throw distance?
-
ahhh.. :-)
You are use your original JVC glasses right? They will dont works with new model, try change polarisation with them over 90" and zou will see nice bright image.
Because thats i sold my old glasses and bought new one. Original glasses will dont works.
-
Barry bought the new Stewart screen first and used it with his old JVC, without issue. I would assume that his throw distance didn't change but maybe he can confirm.
I say this to possibly rule out some of the questions that are being asked.
Barry, other than the dark 3D experience, how does it look? Is it as bright as your old JVC with 2D content? If so, it has to be something with setup or you just got a lemon both of which I bet your dealer/installer will help you with.

I know that 3D is losing support and popularity but I would find it surprising if JVC suddenly made a new projector that is not compatible with their older 3D glasses. However, I have seen stranger things happen in the AV Industry.
It's worth a shot to see if it works.

Ironically, this is in fact the case. With this new generation of Projectors, the plane of polarization has been rotated 90 degrees.
If one's screen retains no polarization at all, then this doesn't matter, and any 3d glasses will work fine.
But if one's screen does retain significant polarization, and if the orientation of the glasses doesn't match that of the Projector's, then light will plummet dramatically, and the more retention there is, the worse it gets.
With previous projectors, JVC's polarization plane was 90 degrees from other manufacturers, so they required glasses with 90 degrees different from the "usual" 3D glasses available (again this is important only if there is screen retention of polarization). When they reversed that situation with the new line, this actually made their "recommended" glasses produce much darker results on these screens.
I am baffled why they haven't changed their website and manual recommendations for 3D glasses accordingly.
-
ST100 does retain polarization and the RS4500 is switched from the RS66, so he would get reduced brightness for 3D if using the old glasses.

You meant RS3000, eh ?
-
WOW, this is officially the most bizarre thing that I have ever heard of.
-
You meant RS3000, eh ?
Sorry, yes. The RS4500 was the first one where JVC changed the polarizers. So RS1000, 2000, 3000 and 4500 are all the same.
-
Barry, I hope you've figure out the issue with your RS-3000, and the polarization sounds like it has to be the problem especially if it's just occurring with 3D.
If that's the case - sorry for your troubles but YIPPPEEE! I switched a couple of years ago from a Sony to a JVC and was extremely disappointed that, having a polarization retaining screen, I suddenly couldn't watch 3D movies with the nice, comfy 3D glasses I had found after trying several models. Ended up spending a bunch more on the Xpand branded version of JVC's glasses, which were about 1/2 the price of JVC's version. But they are heavier and less comfortable, so between that and the general decline of 3D material I've only watched a few movies in 3D on the JVC.
This would be a nice perk of eventually upgrading to a new native 4K JVC! I had no idea this had been done.
-
I was under the assumption the image was dim no matter type of content he was trying to watch. Is it just 3D that appears to be too dim?

-
Apologies, I misinterpreted Barry's post and got a bit excited since it sounded very similar to an issue I have with my JVC RS-500.
Something definitely sounds off, at the price of the 3000 there should be no qualms about its brightness being so low.

Hey Barry, did you get any help from your installer?

What screen do you have - is it one that retains polarization? That's the big issue with previous JVCs.
-
Yes I am getting help and yes it is a correct screen. Butits going to take a few days for them to come out here.
-
< First I would like to thank everyone for their help and suggestions.
Everything is fine, in fact, terrific with my new JVC 3000 projector and my Stewart 100 screen.
The JVC rep spent 2 hours here setting thing’s up correctly. Then, the picture was so good, he actually stayed for 40 minutes to watch a 3D movie (IMAX Under the Sea!!!!) It was unbelievably good.
Basically, he said my installer did a great job in setting things up mechanically, but the setting on the actual projector, including focus, zoom, color saturation, gamma and so many things need to be adjusted. He took his time explaining to me each setting he changed. I now have three settings: Natural for TV watching, A setting for 4k, and a new setting for 3D. he appreciated when I said it was too dark.
The people at Stewarts screen said to get the 100, not the 300, because the screen would be too bright and would tire your eyes with a projector of 2200 lumens. I mention that because the JVC rep said that he usually gets a headache watching too much 3D, but not so here. The reflection was perfect.
It just worked out so well. And thanks to David and the gang for suggesting the right screen.
-
Glad to hear things are now working properly. We figured it was just set up wrong. Your dealer should have known better to at least make sure the focus was correct. Either way, its nice to hear JVC was willing to step in and help.
-
Damn right.
I should mention that when he first measured lumens it came out to be about 1600. After his adjustments it came out to 2166. The focus needed adjustments as well as the alignment of the colors.
One reason it. Took so long isthat he wanted it on for 20 minutes before adjusting.
-
Barry, I'm so glad everything worked out for you, especially after waiting so long!
-
Keep us posted on any further findings regarding image quality and features.

Hivilux Screen but i tested it on EliteScreen 5D and its was some... on new glasses screen are amazing. :-)
-
Great news. I'm glad you have it working properly and can now enjoy your theater. I know you waited a long time for that projector.
