Interesting that you are first to chime in after every report of a damaged unit but for all the other people reporting a good review you have nothing to add. Just an observation.

If a projector is overly bright for a given screen sisize, a low gain screen (not ALR per se) can be used to reduce the black floor which in turn may enhance the perceived contrast. However, if you have the option, closing down on the iris will actually improve the actual (not just perceived) contrast:

Angular reflective materials , and curved screens also help to retain contrast by preventing washout from nearby walls, Don Stewart wrote an article about this years ago. The gain needs to be between 1.3-1.6, when combined with a curved screen and angular reflective material , it really has the ability to enhance contrast .
Again, these only help retain the projector’s contrast, not increase it. Curved screens are actually a double-edged sword, as they can also degrade the contrast since light from one part of the screen can get reflected directly on to another part of the screen.

Of course all these varibles only work in a near perfect bat cave where ambient light is controlled 100%. Unless the room is near a near perfect bat cave contrast improvements and differences are not going to be realized even the best projector will appear washed out.
I tend to think it’s the opposite. A non-ideal room degrades the projector’s contrast by reflecting light back on to the screen; a low gain screen or ALR can minimize that degradation. The closer to a perfect bat cave the room is, the less you will benefit from the screen.

I was a bit inclined towards the Pionner LX500 as it has SACD playing ability which the Panny lacks but if the picture synergy is better with the Panny and the JVC I will pick the UB9000 instead.
I also own a black diamond 1.4 gain 110” diagonal zero edge screen. Prior to owning this I found that even in pitch black conditions my white walls and ceiling would reflect light back onto the screen and damage the black level. Black diamond has revolutionised the image. It has deep blacks and the colours pop like never before. It is fantastic. I use an Epson LS 10000 and it has improved the quality of the image beyond recognition. If you have dark walls and complete light control then you cannot beat out a unity gain screen for overall quality. In our less than ideal conditions the Black Diamond does seem to put back most of the quality and I’m sure it would provide great black levels with the NX5 which would my choice in your position.

Need more info. As in what is your room like? What size, aspect ratio and screen material do you have?

The new projector and autocal firmware will solve the slow start up time. Will add the color profiles for the Panasonic BD players. Will correct the problem of restoring the INIT file and a few other minor fixes. Does not address the yellowing.

Installed update = takes a while – over 20 minutes-
Just messed around a bit -
Just mostly checked the yellowing
of the whites with DI –nothing fixed there-
May be worse -
Slight change in behaviour now- you can trigger change by just bringing up menu
For example – opening credits/wording on Blade runner (original)-
If DI engaged lettering is yellow- if open menu back to white-
Same under Auto 1/auto 2 or any setting I change-

Maybe 4 to 5 years until 8K or the likes of it makes 4K obsolete.

Oh, Happy Day! The new firmware uploaded successfully (on the initial attempt) to my NX7, only a few hours before Chad B. is to arrive to perform his magic! What a spectacular coincidence!!!

However, I have a question..... I have the UB820 which only maps to 500 nit, while the UB9000 maps to 500 nit and 320 nit. The new JVC firmware (2.01) provides 2 new color profiles for the Panasonic UHD players: Pana_PQ_HL (for High Luminance projector) and Pana_PQ_BL (for Basic Luminance projector). I assume that these are meant to mate with the higher (500) and lower (320) nit settings on the UB9000. Since the UB820 only maps to the higher setting (500 nit), would it be best for me to use the new HL color profile (since that would equate to the 500 nit UB9000 setting), even though the NX7 would actually be categorized as a "BASIC" luminance PJ (closer to the 320 nit level)?

Perhaps they just made it so when the menu comes up the iris fully opens (so you can see the menu text)

Thank you. What I meant by enchanting the contrast is not altering the native contrast. The image we see is a reflection of the surface of the screen which plays a part in final image your eye sees. So if grey screen shifts the black to look more blacker then the eye perceives it as much blacker - However if it did the same to white then of course we are back to square A.

You could try it both ways but I would think you would match the setting that you are using on the Panasonic player. If that’s a 820 then select the HL. If you have a 9000 then just match your selection with the JVC.
Remember the TV type settings are only effective if your using HDR/2020 on the 820.

That's what I had been planning to do, but I thought that others here might have definitive information. Kris D. might have already massaged this issue this with the folks at JVC since he's indicated that he'll be part of a demo at the end of March. I'm hoping that he's now able to be a bit more forthcoming since the new firmware has been distributed to end users.

BTW, I can't imagine ANY reason to use other than HDR with the UB820's Optimizer enabled for UHD source material. It's looked uniformly superb for BR & streaming, so it's quite hard to imagine purposefully remapping to SDR BT.2020.

Yes with the 9000 you have the choice of using the high luminance 500 nit or the lower luminance 300 nit. With the 820, only choice is the 500 nit.

Also don't assume firmware update time will be the same for everyone. It depends on what firmware you are coming from. The older your existing firmware, the longer it will take to update. Just follow the instructions step by step and let the projector finish.

Are you positive this is new behavior for you? Bringing up the menu has always fixed the issue for me and I'm positive of that because I was trying to capture the yellow effect while also displaying the info screen and it found it impossible to do so.

That was understood. The question was which of the new JVC/Panasonic color profiles best suited the UB820.

I just looked at "Lucy" and several of my "go to" You Tube UHD HDR clips via the UB820 (Optimizer "ON") and the new JVC-Panasonic color profile (High; 500 nit). The images were absolutely gorgeous. A new finding is that, although the manual sliders remain enabled for picture tone, bright & dark levels, the NX7's auto tone mapping feature is no longer accessible when the User mode for the new JVC-Panasonic custom gamma is selected. Interestingly, the picture tone was set at +9 (bright & dark tones= zero); I assume that's intentional tone mapping as a feature of this synergy.

Mike,

With the new color profile, do you still need to send sdr2020 from the ub820? Or do you need to send HDR2020?

With the color profiles you would send HDR.

For example – opening credits/wording on Blade runner (original)-

If DI engaged lettering is yellow- if open menu back to white-

Same under Auto 1/auto 2 or any setting I change-


This is the as-is behaviour - my PJ has the same behaviour and I am on 1.17 firmware. Bringing up any menu disengages the DI and image is brighter with no yellow or any artifact

Reading your post seems like this round of FW update has not fixed the yellowing DI issue.. too bad

This isn't a new behaviour (although we believe you that you haven't noticed it before) .

Bringing the menu up has always forced the iris open, so the yellowing/gamma artifacts would always disappear.

It's in fact one of the best ways to see the difference between DI/no DI if you don't have the commands in a remote/iRule.

Pause, and bring the menu up and down. You'll see what the picture would be with the manual iris, and in which way the DI transforms the picture.

Of course the closer the manual iris position, the longer it takes for the picture to stabilize.

@Mike Garrett has already confirmed that this f/w version (V2.01) didn't fix the DI artifacts.

JVC are aware and working on it. I guess they have to prioritize issues and fixes...

There will be other f/w updates, hopefully soon.
