Just got my NX7 (to replace faulty NX5), gotta say big step up in PQ...

One question, can someone explain how the color filter works? What exactly is happening inside the projector when the filter engages and how does it expand the color gamut?

When you select BT.2020 as your color profile the filter will engage in the projector allowing the higher color gamut.
This is preferable if your screen size is not that large. When the filter is engaged there is a loss of output.
You should experiment between the HDR color profile and the BT.2020 and see which one you prefer.

That is awesome to hear i was worried that i would lose light output for HDR content cause of the AT screen but you have a bigger screen than me. I wish i could go bigger but my room width and speaker doesn't let me. I will have 2 big L/R Speaker beside the screen and the center channel behind the screen. Thank you so much for the reply.

I left CMD on, and sure enough, under 10h this “bait” worked.
Time to contact JVC, now that I have pics.
I have a May 2019 build, supposedly from the serial number.

I understand that, I am just curious about what is happening, how does the color filter change things? This is all kind of strange to me, Rec709 was such a constant calibration with everything known and now with UHD / HDR there seems to be a lot of preference and "what looks good to you" going on?

Are you running 2.07 firmware? If not, update to 2.07 and see what happens.

I cannot understand how that can be a hardware fault, such a regular pattern with no vertical color change and no input ?

Is there some hardware component that could induce such a pattern ?,

Mike, his first picture shows he’s at v2.07. JVC needs to figure this out!

None that I've noticed. Folks using an anamorphic lens have no complaints about the scaling done there either.

Just trying to help. I did not see it as my responsibility to go back through posts to try to determine what firmware he was using, so asked the question and told him if he was not on 2.07, that would be the first step. He already has 2.07, so no other option, other than get with JVC to resolve. Would also have been nice if he had listed what source he is using, when he got this, but again, I am not going to go back and read all his posts, trying to see if he previously mentioned.

Yeah and the zoom scaling is such a tiny rescale.

Just because the projector isn’t great upscaling 1080p to 4K doesn’t mean that the scaling from 3840 to 4096 will also not be great.

In fact the scale is doing very little so it maintains a lot of the original sharpness.

I have a 130" (Diagonal) 2:35:1 screen and a 120" 16x9, most of my watching is on the 2:35:1 screen
With the lens it won't use the entire 4k panel, but increased light output using the full 3840 x 2160 resolution.
Without the lens I can use the entire panel with the correct projector setting, but zoomed? uses the full 4096 x 2160 panel, which yields slightly increased resolution and light, but more than using the A-lens?
As long as the lens is capable of resolving 4K, I'd use it. You'll get more overall light output. You may also consider removing it for non-scope content like 2.0:1 and 2.20:1 using an installation mode/lens memory to avoid cropping (and you could use the full panel here).

That is the funny thing about contrast ratio....

On Wikipedia, "There is no official, standardized way to measure contrast ratio for a system or its parts, nor is there a standard for defining "Contrast Ratio" that is accepted by any standards organization so ratings provided by different manufacturers of display devices are not necessarily comparable to each other due to differences in method of measurement, operation, and unstated variables"

Each item would have to be texted exactly the same and in the exact same situation to compare any results......

I wasn't criticizing you Mike, you are consistently helpful in this thread! I agree, it would have been helpful for him to note his source, and his firmware.

With the same lens as my RS4500, I'm not surprised you find the NX9 super sharp. I find the picture to still amaze me after nearly 2 1/2 years of ownership. A lot has to do with the lens for sure.

So far all my issues have been with a Panasonic UB820 and in HDR mode (with CMD on Low), but that's the bulk of my viewing.
I upgraded from 2.06 to 2.07 on Day 1, but I haven't done a factory reset. I could try that.

You definitely need to be talking to JVC, because you are not doing anything out of the ordinary.

Yes, if you are at the short end of the throw, but that 1.1 gain number is BS. Probably closer to 0.9, though I have never seen the material. But I have seen a lot of woven AT screens and I am yet to see one above 1.0.

The RS2000 is up and running finally. FW 2.06. I'm staying on 2.06 to see if I get the green lines issue; 2.07 doesn't fix it anyway from what I've read. I haven't seen yellowing issues no matter what color profile I use. I keep trying to find them during films and I just don't see it.

I had to make some minor adjustments to the color alignment, but not a lot. I wish the uniformity of the color alignment was better. It's good, but around the edges of the screen I see a little bit of misalignment. I can fix that with zonal correction so it's not a big deal.

The projector is more than bright enough for my 135" Silver Ticket White 1.1 screen. However, I'm not happy with the auto-tone mapping feature. When I use MadVR I can adjust the HDR dynamic mapping to retain the benefits of HDR without graying/washing out everything; and to handle multiple films without adjusting for each one. If I'm watching Netflix from my PC, however, it sends the metadata (directly from Netflix; not the Win10 default metadata) but even with the mapping level maxed the image is not vibrant or bright enough. I've decided that for each Netflix film I start out letting the projector auto-tone map to start out and then turn that off to bump up the image tone manually a couple notches. It's not even a projector brightness issue because I can zoom the lens down to a tiny 77" size and it's still not bright enough. SDR content is bright enough no problem. It's really the metadata and auto-tone mapping not being able to compensate for it enough. I wish the mapping level went from 0 to 10 rather than 0 to 5. I don't care if there is some clipping. That's to be expected. I'll decide how much I want. I might need to do some custom gamma curves to get what I want on non-madVR content.

As I said before, however, MadVR content is beautiful. I'm running the new dynamic HDR builds and they do great. Set it and forget it for all of the movies I've tried so far. I wish the projector would accept my 12-bit RGB 24p signal and not lie to me while forcing it to 4:2:2 (as pointed out by Manni), but otherwise my UHD HDR Blu Ray experience is pretty great. Maybe JVC will fix that issue in the next firmware (it's not actually fixed, just hidden in 2.07 so I hear). It's really easy to tell when the projector is forcing 4:2:2 because you can set the chroma on the projector to RGB and the colors go wack. When running 8-bit RGB, forcing the projector to use RGB works fine.

The fan on high is a touch too loud, but it doesn't bother me. Maybe I'll put some diverters on the front vents. The lens shift is very grindy. Zoom is smooth and quiet and horizontal lens shift is fine, but vertical sounds like a 1980s printer. Not sure why. As long as it doesn't break I'm fine.

Another complaint... the pixels are not tack sharp. I'm not expecting a Christie level chess-board-quality layout, but even with better color alignment in the center and close adjustment of the focus, it really isn't super sharp. I would like to see the QuickBrownFox pattern on another projector to compare (not just screenshots). Maybe that's just how these new 4k projectors are. It still looks great, but not as great as I would like.

Definitely I am happy that I put black velvet all over my room for this projector. I actually would go as far as to say that without the velvet you should probably get a different projector with a lot more brightness that sacrifices on black levels. Don't even waste your time with JVC or Sony unless you are doing a dedicated blacked out home theater. I'm sure many will disagree. That's fine.

So... was it worth it? Yeah! I'm not aware of anything better anywhere near the same price point and I got a great deal on this thing. Maybe I got a bit of a lemon on sharpness and color alignment? Dunno. I guess we'll find out when I compare it. I might go for a nicer higher-gain screen next to help that image "pop" more with a bit more brightness. We'll see.

Mike, just considering the Cima Neve 115 or 125 2.35...stated 1.1 gain...I’ll have about a 14ft throw, batcave, N7...do U think the N7 can adequately light up a 125 2.35 Cima Neve for HDR or would u stick with the 115”?

The JVC at short end of throw range is bright enough for the 125, especially if using the UB9000. The 115 will give you longer lamp life.

Thanks man, i just don’t like non bright images...the drawback of going too big is “dullness” whereas I know I won’t have that issue with a 115” but I don’t want to regret buying too small! I’m using an 820 BTW...I need to see a dr I think! 🤪

Finally got my NX1000 from JVC, which is replacing unit that took forever to boot up. New projector boots up much faster and its lens appears to be more uniform!

Just as my wife predicted though, new unit isn't perfect
  1. I'm seeing "dancing" streaks on convergence adjustment menu as it appears in the bottom right corner. Regular projector menu on top left corner is fine though.
  2. When doing pixel convergence adjustment, i'm seeing a slight greenish tint above all horizontal lines on the conversion grid. I can't get it to go away by shifting Red or Blue pixels. Is this something that people experience often on these projectors?

Hi guys, just un-boxed and fired up my new RS2000. Yay! Uh-oh

There is a blue banded tint on the bottom 6” of the image across the entire screen. Images below. Is there an adjustment or is the unit defective?

It still looks great, but not as great as I would like.
Maybe it's just sample variance, you probably got an average sample, which isn't bad considering it could have gone either way.
