Not sure if this is enough to prevent the issue from happening, but this is what you want if you want to prevent any unwanted processing.
Correct, I should have been more specific. I have HDR (and Natural) mode with everything turned off, but a user "game" preset with low latency turned on. I have had the blue bar issue, while using each mode so I can seem to find a pattern.

If you get tired of buying plates, get a 1/2" or 3/4" piece of plywood, paint it black, drill a few holes and make your own plate..... You could probably reuse it again, and again, and again down the road....

When switching color space from 422 to 444 on the NX9 I see this. Does not happen on my RS500🤔

That's actually not a bad idea. I might try that before I go ahead and order a Chief mount. There wouldn't be any kind of movement, but I also don't really need that. Which could end up being a good thing. Could even go with MDF I guess.

The new JVCs don't support RGB or YCC 444 in 12bits (this is in fact stated in the manual, even if there is no reason for this limitation, at least from a bandwidth point of view). They force an internal conversion to YCC 422 whenever 12bits is used, even when the frame rate is 30p or below (so when the 18Gb/s bandwidth limit isn't reached), yet they display RGB or YCC 444 in the info panel. JVC knows about this, so hopefully a fix is on the way, provided this isn't a non-bandwidth related hardware limitation.

So if you select the colorspace manually when sending 12bits from the source and are not using AUTO in the JVC, you get the wrong colorspace unless you manually select YCC 422.

If you select AUTO, the colorspace is still forced to YCC 422 internally when the JVC receives 12bits 444, but YCC 422 is AUTOmatically selected so the picture doesn't look obviously wrong (though chroma might suffer from the double conversion).

Bottom line is, until/unless this is fixed/improved, you should only use RGB 8bits or (YCC 422 if you really want 12bits), otherwise you can get the wrong colorspace (if not using AUTO) or chroma upsampling issues (the JVC does a chroma conversion behind the source's back when forcing YCC 422 internally).

With madVR, I recommend RGB 8bits Full. This means that madVR upscales from 420 to 444. There is no banding if the other settings (especially bit depth and dithering) are correct.

With a UHD Player or other consumer sources, I recommend YCC 422 10 or 12bits. This means that the source upscales from 420 to 422, and the PJ upscales from 422 to 444, which is fine. There is no colorspace and/or chroma conversion happening behind the source's back.

These are the only two modes that do not suffer from the forced YCC 422 conversion in 12bits and the potentially related issues.

Again, it is recommend to switch low latency ON (CMD forced to disable) and motion enhance OFF in all modes, whether video or gaming. You can use these processing "features" if you don't get artifacts and if you like the results, but if you get issues reverting to Low Latency ON and Motion Enhance OFF should always be the first step.

However, a little different story how bug was shown. After 27 hrs in the middle of GoT, latest episode, while streaming from HBO app in Samsung S4 tablet green pixels started to show in picture and finally larger areas of greenish blocks corrupted the picture. I opened main menu and it started to show stripes, bluish and pink stripes in menu window and menu itself was also vibrating rapidly. No stripes in picture itself, only those green pixels.
Next I only changed iris from auto2 to manual which didn't help. Power cycle did help and rewatching problematic point in the episode did not show any corruption.

I have Ruipro 10m cable between N5 and Denon AVR-X4500H. Picture mode was in user mode, color profile SDR709 with custom gamma 2.3, brightness -3, iris auto 2, -9, low lamp. Info window showed 2160p,30fps and RGB 8bit. Upscaling in AVR was disabled.

This was first sign of any failure or bug. I think it was not the case of overheating or problem with the cable or in signal path. I had projector on for couple of hours before it happened. Day before it was on for much longer period of time.

Otherwise I am quite satisfied with this projector although it does not have the best convergence. Projector has also so many options that it takes a lot of work to get picture quality right for multiple sources I have. And I have not yet touched 3D.
I've had what you describe on my rs1000 once which I described some pages back. I had to power cycle to clear it. It has not happened again.

Only other thing I've seen is that my roku is quirky connecting to the projector. On startup sometimes I have a black screen and I need to switch inputs away and back to get it to connect. I've also found it showing white noise after it sat idle for some time. Only happens with the 4k roku player and switching away and back reconnects it.

I noticed that you use a Denon receiver (as do I) and I'm curious if those that have experienced this issue are using a Denon or Marantz as well. If anything, at least we can rule that out.
I just replied that I've seen this too and yes, I have a new denon x6500h.

Sure, low latency ON disable cmd but i suspect that even low latency, if engaged, can be the or one of the causes for the vertical bars issue when watching movie content.

A lot of us have Denon receivers with the problem. However I also bypassed my receiver and hooked my Xbox one x up directly to the project on 2.04 and could create the problem.

On 2.04 vertical line issue I was having a problem I could reproduce. This is what I found as far as settings with the CMD settings on that issue. I'm not sure this is a definitive guide to the vertical line issue. But it was something I could test. You will also find if you change some of these settings after the blue/green/white bar issue occurs that the color of the bars will change.

Thank You Manni!!

Excellent information. I purchased the NX9 last week when I notice this. Also after a few hrs of viewing these green vertical lines pop up across the picture. I informed JVC of this and they recommended a new firmware V2.05 I completed the firmware update and again the lines pop up. JVC was very accommodating offering me a replacement, but I decided to return it until these issues remedied.

Thanks for your help.


I’m using the RPA281 and it’s solid. Ceiling extensions center on the projector once installed.

that's very interesting. i hope they get this figured out with a future firmware, but like you i also have a replacement coming just in case.

They all look absolutely fantastic to me. Switching settings takes long enough that I can’t seem to pick up on any major differences. Love to hear any thoughts. Cheers!
Tally me up for option 2 as well. I tested it pretty hard and found it to be the best of the three.

I'm willing to take a bit of a hit in brightness going with the AT but worry it will be too much of a hit and no stores locally have the JVC's up for Demos...

Agreed with the above Nate. Of the close to 30 samples I have of different materials, the elunevision was absolutely the furthest from accurate (yes I actually got a sample somehow). Stewart was too steep a price for me too so I rolled with the severtson 1.3 microperf. I have been extremely happy with it and it was darn near close to the stewart st130. I wouldn't hesitate to suggest it. The stewart Cima Neve Perforado was also excellent. None of the weaves get quite to unity gain..you have to go MP to get there or above FWIW.

Also, I have the NX7 now at 1.6x throw to a 135" diag. scope screen and the image is fantastic. Go with a 1.3 gain material and you'll have plenty of light for HDR even.

I can't find a pic of your setup but should be something like this without AT screen.
Maybe in reality it's not bad but the closer you sit the AT screen is more likely needed to keep the middle of the screen as close to your eye level as possible to avoid this looking up situation.

Any owner here with AT screen who's sitting relatively close?
Considering the above information and that I am sitting ~12ft. and I am extremely happy with the results. With a good Microperf material you can't see the holes at all. With these woven variants, they perform even better. Even with your nose against the screen with the v6 you can see any holes.

Does one of those samples happen to include the XYScreen material claimed to have a 1.8 gain?

No but you have my attention with a 1.8 gain if there is no shimmer. Anything I tested above 1.3 started to have the sparkles and I can't handle that. I will see what I can get crom XYXcreens.

Did you ever test out Severtson 2.2 or 1.8 ?

Also, I have the NX7 now at 1.6x throw to a 135" diag. scope screen and the image is fantastic. Go with a 1.3 gain material and you'll have plenty of light for HDR even.

Considering the above information and that I am sitting ~12ft. and I am extremely happy with the results. With a good Microperf material you can't see the holes at all. With these woven variants, they perform even better. Even with your nose against the screen with the v6 you can see any holes.
Hi beastaudio...how close are your speakers mounted behind the Severtson 1.3 microperf? About 12" or can you mounted them within a couple of inches of the screen?

Thanks,
Ralph

[QUOTE=tommarra;58047504]Have you tried Elunevision - their 1.0 gain for AT material is totally incorrect and they don’t give out samples. Their gain is closer to 0.8 - so make sure you are still able to do good HDR.

When I was buying my own AT screen - I was considering them but since they don’t give out samples to compare with V6 or Seymour I decided to not go for them


Hi tommarra...what were the major factors for why you chose the Soundmax screen over the V6 or one of Seymours? Screen gain? dollars?

Thanks.
Ralph

Primarily the higher gain and the super low price. My 130 inch 16:9 screen was less than $800 shipped. I figured even
if I didn't like the screen I could just upgrade without too much pain at a later date.

But when I got the screen the image quality is amazing (coming from Elitescreens Cinegrey 5D - the worst material ever made IMO)

There is a thread on AVS wherein the OP compares XY Soundmax to other AT screens. The designer of V6 also pitched in and ran compares of the Soundmax material to V6 and even he found that Soundmax has ~20 percent higher gain than V6 which puts it near unity gain. (~0.95 gain)

To get 100 nits for a screen size above 120 inch 16:9 screen you just cant do it with V6. Only woven AT screen that can do this is XY Soundmax - I think!

Now in terms of audio Soundmax attenuates the high frequency the most (4-5 dB above 12KHZ vs 1-2 dB for V6) but that can be very easily fixed by simple EQ.


I think in terms of value you can't beat this screen.

I also have a Severtson Cinema White microperf in 2.35:1 135" for use with an NX7.

My first row is 9 feet away. I can see the holes and a little sparkles (only in the center) when the image is mostly white but when it's any other color they're invisible. Depending on your vision, I would think you would not see the holes at all 12'+ from the screen.

Also, my speakers are 6" from the back wall and 5" from the screen and they sound great.

All in all I'm happy with this screen.

I filled out the "contact us" form on the JVC professional products website and got a response from Chris Deutsch of JVC.

Thanks for the info. Maybe they just ignore queries from european users. Nevermind, probably "Out of scope" close ticket

I really liked the Severtson 1.3 sample I have too and will almost definitely be going with it for my next build. 160" Diagonal 16:9.

Have you got any recent images of your screen in place?

Is the velvet on the frame good? Any pics on putting it together, the backside of the frame etc?

And how far back are your speakers from the fabric?

I have just placed an order for a 120" 16:9 masking screen from V6. In a batcave room, how many nits do you think one can possibly get when paired with the NX7 ? Temporarily, I'm using a solid Stewart Grayhawk and since there is no ambient light reflecting back, i'm guessing this may cause the image sometimes to look dark and I also wish the colours popped more, maybe the grayhawk is not 4K compatible.
