Do you mean the little squares (that have either a solid fill, or the horizontal vertical or diagonal lines)? Or am I not looking at the right areas?

If that's what you mean, I do see the yellowish hue, with the boxes with the horizontal lines showing this the most, in multiple areas, with some of the solid ones showing it as well.

I guess the way to prove this is from the zonal adjustments would be to reset these, and repeat the pictures. Do you know if this has been done?

Again, I'm not saying this is not the case, just that I recall someone (can't remember who, couldn't find the post, but my memory was that it was from someone whose knowledge I respected) saying that despite many people saying it was harmful to final picture quality, that in fact it wasn't.

There are no solid fill areas in the actual test patterns. They are vertical lines, horizontal lines and diagonal meshes with one or two pixel-width lines at 4K resolution.

Yes, the issue went away when I reset the pixel adjustments.

I first saw the issue with a static image that contained a white background, which contained yellow botches in areas where I made the fine adjustments.

Both have advantages, and you have to tweak until you get it right. The white and black tone adjustments help, along with the slider.

Ultimately, it's what we each prefer individually.
It would be great to use just one, but all this different content we have requires different things.

What frustrates me is how it makes the JVC macros somewhat counterproductive. If I switch to HDR from SDR2020, and I have to back out to the top menu or something, when I go back it will switch my profile. In fact, JVC doesn't even list "HDR" under the macro profile options, so you can't switch to it anyway.

Good of you to clarify this.

It then makes me wonder: if the initial misalignment (that using zone adjustments is intended to correct) is also not evident when watching actual content (and I understand that isn't what you just said, but might be the case), and the negative effects of zonal adjustments to the misalignment are not apparent, then are we just chasing our tails??

In other words, do these adjustments, whose need is determined by 'pixel-peeping,' have any net positive impact on picture quality when viewing actual content? Or does it just satisfy the OCD that so many of us (myself included!) suffer from?

The colour fringing from misconvergence is visible to me whenever I call up the JVC Menu.

Feeding SDR2020 from UB820 but PJ info window says HDR

I have read first post and followed recommend setup,
Gamma set 2.4 and SDR2020 from UB820.
When movie is played, on info window under PJ menu says "HDR: HDR"
Did i do something wrong? as far as i understand, it should say SDR2020 not HDR.
Is this means UB820 still sending hdr meta data to PJ?

Sorry if this question has been addressed already.

I just picked up a Panasonic UB820. I currently have a UB900 paired with my RS540 which was calibrated by Chad B. Is the HDR Optomizer on the 820 a significant improvement over the 900? Still debating if I need another $500 disc player. Sounds like there is debate on how to setup the 820 with the JVC series.

Try manually selecting your custom picture mode you set up for sdr2020. Use a sdr title in the 820 then switch back to an hdr title. Does the jvc stay in the custom picture mode or switch back to hdr?

Please confirm where you made the sdr2020 selection on the 820. Was it the menu where it had just the hdr2020 option and the sdr2020 option?

No, not happy. Ecstatic. I'm less than a month on a new RS540 and the PQ exceeds my high expectations. Out of the box was very good, but Jeff Meier was in town this week and he absolutely smashed this thing. The calibrated image blows even my wife away. It's exceptional. Plus the price point on this machine makes it a really strong value proposition. IMHO YMMV.

Thanks for your post and for informing me that there's another highly recommended calibrator, who's located closer to me since he's showing April tour in my area and ChadB has nothing scheduled.

Disc is reporting 1000 nits master. 285 nits MaxFALL

Im betting the real nits are well under 1000 though.

I want to relocate my new X7900 into a small attic behind the back wall of our HC room, but before punching the projection opening thru the wall I'd like to know if I am not doing something counter productive putting the projector further away.
My screen is a 4K AT wowen screen with a black baking and a 0.9 gain, it is 8 feet wide and the new throw distance will be 15', isn't that too far away ?

Dont think so. MadVR is a renderer and requires a player that will use this renderer. The netflix app won't. It probably could, but it doesn't. (The netflix app on pc is terrible, won't even work with simple arrow keys so you are stuck using a mouse. I unsubscribed to netflix because of it).
There may be ways to run blurays off disk through madVR but for the most part, it requires ripped files on disk. ITunes is definitely out.

Your peak lumen output will drop, but contrast performance will increase. How is your current setup as far as image brightness for sdr and hdr content?

Given the excellent contrast on these projectors, placing the unit as close as possible gets you max lumens on the screen, while contrast performance is still very good.

Also keep in mind as the lamp ages tge lumen output drops, so if the longer throw is right on the edge for image brightness, it will get worse, needing you to run high lamp sooner or more often.

I have no non hdr title so I played blu-ray and set picture mode custom then i switch back uhd hdr title, picture mode doesnt switch back to hdr and it stays but it says HDR as i mentioned.

and yes 820 set to sdr2020 and status window says its feeding sdr2020

btw my jvc is x590r, is this a problem?

I have my projector mounted to the ceiling with no extension on it - there is a door to the attic behind it, so the 14” extension rod that came with the kit wouldn’t work. The top of the screen is about 1.5 feet down from the projector and I have it angled down with a keystone correction of -5.

Would I gain any benefit from installing a 3” (May have room for a 6”) extension?

I think you'd be better served by leveling out the projector, zeroing out the keystone, and then using the lens shift to get it into the screen. I'm not hip to the specs, but I think you should be able to cover 1.5 feet. I could be wrong.

It's 1.5' from the top border, then probably another 2' and some inches to the middle and then 2' and some inches to the bottom. You think the lens shift could make it that far down?

It’s easy enough to try.
