https://madshi.net/madVR/ChromaRes.png

the screen is completely insane in terms of presentation and procession.

in filmmaker i got blue and pink lines i have no clue how the TV did that.
game mode
perset standard (in custom the color space is messed up i guess)
144 hz
sharpness 10
and the other stuff disabled like CR enhancement and so on.

gives me accurate 4:4:4 on a sub sub pixel level. i only test SDR.

isn't S&M an encoded disc? that means the chroma needs scaling to check placement madVR does this wrong for UHD and the old S&M disc did chroma wrong not following the spec they may fixed that in the new one but...

Anybody having problems with latest 31.0.101.5590 Intel Graphics Driver on UHD Graphics 770 and madVR renderer? Image looks like white noise.
@nevcairiel acknowledged reports about this.

How do you interpret the results of the Chromares pattern? What should it look like for full 4:4:4 chroma?

you should be able to see the 444 name and notice the blue sub pixel in the pink part around the 444.

the checkboard pattern around the 444 should have a similar color like the boarder which is solid color. it could be a bit darker or lighter then the boarder this depends on your gamma.

422 part should show you blue and pink lines on the top and bottom of the letters because they are 2 pixel there. a skilled eye will also see the individual liens in the 422 if you are close enough. no need for pixel peeping.

this pattern does not work when any sharpening is done like the CR enhancer and sharpness does.
for sharpness i use this:
http://www.lagom.nl/lcd-test/sharpness.php

you need to get far away from this pattern so your eyes can't see the individual pixel.
i open both of them in paint and leave them as is yeah quite small these days.

i'm not even sure we have the same screen...
https://www.avsforum.com/cdn-cgi/ima...l-png.3626471/
this is amazing
i have a red tint in warm1 and even with bt 1886 at -3 i'm not at gamma 2.4. i mean wow yours is just amazing out of the box.

i'm not confident in this screen behaviour yet there is a lot i could have missed.

Thanks. Did you try to use the exact same settings I am using in FMM at 4K120 with pc mode and game mode disabled? What is your exact model and size? If under 77Ē you might have a gen 1 panel. Letís discuss calibration in my thread as I think itís fairly off topic here (apologies everyone).
Iíll just post my chroma results here when I have a chance to check it with the chromares pattern.

144 HZ it seem to be able to do 444 outside game mode.
CR enhancer and other settings will result in a subsampled making 444 checking really hard on this screen.
i only have entertain and graphic mode at 144 and currently there is no point in not using game mode at this refreshrate.

in filmmaker mode at 60 HZ i got the chroma test pattern to flicker and sharpness to only change the left side of the screen when i put it at 20 for testing.

i will do 120 HZ later there are a lot of setting i have to redo which could give me a false negative.

it was sold as an GQ55S90C this version wanted to default to "Niederländish" netherlands i guess in english.
this is is not the german or english edition i guess.
the internal name is QE55S90CATXXN. that supposed to be Austria.

You might have a gen1 panel if itís a 55Ē. These might not measure as well, but you would need to measure FMM at 23p with my settings to see if itís game mode ruining your calibration (it probably is, thatís why I donít use it).

I can confirm that as the S&M and quick brown fox patterns suggested, I get full 4:4:4 with the chromares pattern at 119p in 4K in FMM mode with game mode and PC mode disabled. No idea what it does outside of that, I haven’t tested it. Sharpness at zero as per the settings posted in my thread.

game mode has not negative effect on calibration at 144 HZ.

FMM 120 doesn't exist here i can't even do more then 60 hz with disabled game mode. yes you can disable it after entering 120 HZ but still no FMM. so i can't test what you are asking for.

You need to also disable PC Mode in order to get FMM.

To disable PC mode, press input, edit your HDMI input, and select anything but PC Mode (I selected Home Theatre System).
I can only talk about 4K119p HDR FMM with Game mode and PC mode disabled, as that's what I use for playback (well, 100/119/120 depending on content refresh rate) and calibrate for.

Just tested with the OS set to SDR, and I only get 422 in SDR 4K 119p. That will explain why I get 4:4:4 in the QBF pattern and the S&M patterns, as I'm now using OS HDR to limit the number of HDR-related HDMI syncs. JRVR plays SDR content fine within HDR since build 55.

So try to enable OS HDR and see if you get better results chroma-wise.

So... how do you know you are getting 4:4:4? In my experience the QBF and S&M patterns are not reliable.

I think your display is converting to 4:2:2 internally with better than expected results, but not true 4:4:4. I noticed this behavior with my Samsung S95B (1st gen QD-OLED).

Calibrated SDR with the OS set to HDR?!? How does that work?

Read the last few posts, I used chromares to validate 4:4:4 in a very specific configuration (4K120p 10bits HDR no pc mode no game mode). Also I have an S90C (2nd gen QD OLED), more recent than your S95B and with full 48gbps HDMI 2.1 (no crappy OTB limited to 40gbps).

As explained, SDR within HDR works fine with JRVR since MC32 build 55. When OS HDR is enabled, JRVR converts rec-709 BT1886 to bt2020 PQ. Off topic here, of course.
