Excuse me, I did not mean to bother you.
Watch this conversation, Seegs talks about the good uniformity of your RS500 and for whatever reason (shooting angle, screen ...) does not look like it.
LCD/LCoS gray uniformity
Seegs in this same conversation states this:
(...)It's not common to other projector manufacturer's expensive units. For instance the Epson LS10000 I demo'ed looked excellent and showed none of these issues.

This is why using photographs is sometimes misleading.
What really matters is what you actually see.

Amazon has a pre-order below. There is a rumor of only 6000 being released in the US and will be numbered with a JC signature so I ordered 2...

Will tie up the Oppo 203 with the Rs600 just to see what results I get.
I have UltraHD discs of Sicario, Passengers and the original Ghostbusters which all look splendid on the 1000es in terms of resolution.

Very curious to see the effects of WCG with the Rs600.
Also need to determine if I have the bt2020 profile pre-loaded already onto the machine(which is the 2016 model)......otherwise will have to download from the JVC website.

So far with the Rs600, just been enjoying the show with rec709 BluRay content.
Absolutely amazing all round picture quality.
Blown away
With the 203 and the RS600 the JVC will default to Gamma D for HDR content. Even with the best case settings it's still a mile away from the custom curves you may have been reading about. You can install one of the universal curves that Manni01 and LovingDVD created, they are good baselines to at least get an idea of how it would look. you would have to switch to the custom curve once the movie starts since the JVC is aggressive with wanting to default to Gamma D.

The ultimate 'set it and and forget it' solution will be adding the HDFury Linker (http://www.hdfury.com/product/linker...600mhz-scaler/). It has a specific feature that the Integral doesn't that will allow the DI to work in HDR and also keep your custom curve as default when playing back UHD HDR content.

There's a number of movies that look remarkable in WCG, the RS600 has full P3 support once the filter is engaged. Lucy, Fifth Element, Leon and Dawn of the Apes are some recent viewings where the WCG really stands out.

I can't agree with that I'm afraid - just because you own a JVC does not magically make you scrutenise an image more or a suddenly become a video guru. I could possibly say that I put the JVCs under more scruteny because I actually decided not to buy one based on the image they produced. You can't get much more critical than that. I could go further and say that the JVC owners complain more because there is more wrong with them. Most people buy them for the contrast it would seem.

I don't either if they are genuine. Having checking out my uniformity today after watching a movie, I can confirm mine doesn't have an issue either, just as I said many times perviously. Maybe owners with the issue are using too much of the convergence control.

I have no idea if it's just the camera, or how bad it would look in person, but Seegs isn't just seeing things.
Honestly the left side looks fine to me, and I don't see the green at all, but I do definitely see the magenta on the right side
Thanks for doing the same as me. I don't see it in real terms either (on either side of the 40IRE image) and my colour picker shows up similar small differecnes to yours, but they are not in large areas or big enough to make as visible a difference as is being suggested IMHO. I mean, 149/151/150 out of a range 16 to 234 is unlikely to be that visible is it. When calibrating to D65, the RGBs are usually shown as 100% and the differences can be 1 or 2% but that doesn't usually equate to a dE greater than 3 which is where the differences start to become visible to the human eye. If it's not visible on the screen it's also possible the camera has made some errors, but looking at the images on two different monitors shows it to be fine to me.

I wonder how JVCs and Sony's would look when using a colour picker in the same way after being photographed - I bet they have differences greater than one or two and would not be say 150/150/150 across the entire screen.

I'm thinking maybe zoom or lens shift, but probably just luck of the draw.

I can't see the green and red that he mentions, and neither can my paint program, so I'd like to know why.

Can anybody else? Did anyone else check it in their paint program to confirm it? The RGB values are all pretty close, and those that aren't don't confirm the green to red imbalance he sees, so I'd like to know why. If it was my eyes or monitor, the paint program would show that.
Yes. Have you got photoshop?

Left side is fine to me, close enough, right side would be dE over 3 sorry to say, thats visible to the human eye and thus probably approaching dE 4 or 5.

For the 10IRE Shot...

Right side of screen:



Top Left,



Bottom Left:



40IRE actually looks about the same to my colour picker.

If you measured 150/150/150 for eg as Gary says, that would be a dE of 0.0 which is almost impossible. I mean, seriously, pretty much no projector would have that level of uniformity IMO. Expect a spread of 3-5 for a fully calibrated projector.

Was playing around with a UHD Remux last night, I noticed through MadVR, not only does the HDR passthrough as expected and play perfectly, but you can also turn off send HDR metadata right there in the MadVR settings, this stops the JVC Autoswitching, and of course, retains the DI without the need for the linker at all. That option has actually been there longer than the Linker has been able to do it. Which is good, because my linker is between my Panny and the AVR, not between my HTPC and the AVR

Cant wait until I can back up all my discs this way.

Thanks for doing that which was pretty much what i found I think - no real green to red uniformity problem. Having said that, with the images you have posted I can now see the blue tint on the right hand side a little more, which is strange - I did measure that but it wasn't as visible. Has photoshop enhanced the images at all in any way? Seems more visible in the 'preview post' than it was earlier.

That was my point about the actual measured differences, which are pretty small and inconsequential in the most part. I would think a camera would change those measurements to a degree as well, especially a phone camera. Even if you had 150RGB across the screen, it probably wouldn't end up like that after being photographed, and with low IRE images the accuracy and noise of the phone could come into play, just like with some calibration probes.

Photoshop doesn't do anything unless you tell it to. The images are the same as what's earlier in this thread.

There is a problem, like I said, that would be greater than a dE of 3 on the right hand side, since its fully visible to the human eye. The left side of the screen though is fine.
