HDR looking terrible on a LG C9 ??

[Nelchior]

Not sure where it went wrong? I have an RTX 2080ti, here are the settings I usually use:
HDR is on in windows 10 settings,
TV isn't in PC Mode
Nvidia color settings set to RGB 8bcp
Playing with Game mode on


It "usually" worls for me with those settings, but right now Death Stranding looks pretty terrible, with darks that are way too dark, and overall kinda washed out colors...

Anyone experiencing similar issues?

I only took a quick look because I have other absolutely ridiculous problems with that game right now.

First you need to actually active HDR in the game as well as windows. For me it didn't do that by default. I get washed out colors by turning HDR on in windows but leaving it off in game.

Crushed blacks for the most part stems from the following:
nVidia control panel->Output Dynamic Range "Full" but in TV-> Picture Mode Settings->Picture Options->Black Level "Low"

Or vice versa nVidia set to "Limited" but TV set to "High"

Correct would be "Full" and "High" or "Limited" and "Low".

Beware that depending on the scene and your own perception the wrong combination could look better for a while. Because it looks akin to a higher Contrast, which enriches colors. But that is not the case. Black detail is sometimes completely lost and in a colorful games colors could get overblown.

Change color settings in Nvidia to RGB 10bcp

These are the best settings to use:

In game:

HDR: On
Brightness: 2
Luminance: 40

On the TV:

Black level Low
HDR Game mode
Dynamic tone mapping: HGIG
Oled Light 100
Contrast 100
Sharpness 0
Color 50
Tint 0
Aspect Ratio 16:9, Just Scan On
Dynamic contrast Off
Super Resolution Off
Color Gamut Auto
White Balance Warm 2

Turn on HDR in the Windows 10 settings menu.
Nvidia control panel: 4:2:2, 12 bit, Limited.


If any issues arise with weird colors or macroblocking: Reset tv to initial settings then apply these settings again.
The game will be dark during certain times especially the beginning because it's cloudy and raining. It'll look different about 10 minutes in when it stops.

No issues running on the same TV and the same GPU.

Yeah, it looks really bad on my C9 as well in HDR. Like blacks are messed up, acting real strange.

[Nova eXelon]

Didn't mention it before but I have a C9 as well. HDR working fine.

Thanks mate!! Im going to try that today.

That said, I see that you suggest 12 bit in 4:2:2 and my understanding was that as long as GPUs do not support HDMI 2.1, then sending the signal in 12bits would create a mismatch with the tv settings and mess everything up?

Ill try that out as well, definitely looking forward to see whether that helps!! thanks

What do you guys think of the settings recommended in the comments here?

Still going to try what Nova & Auron suggested

[Olek]

You have to set 422 10 bit in NVCP in order to get correct HDR display.

[Nelchior]

So 10 or 12 bits in the end? I guess Ill try both but Im afraid I wont be able to tell the difference :-p

Switch from RGB 8bpc to YCBCR 4.2.2 10bpc when you do HDR. 8bpc isn't enough.

That won't work on contemporary NVIDIA GPUs. They only put out an HDMI 2.0 signal and don't have the bandwidth for that on an LG C9 OLED unless you're contempt to run the game at 30 FPS.

You need 8-bit RGB w/ Dithering until HDMI 2.1 GPUs ship.

What would be your TV settings then?

If that is true then how do you explain this:

And according to the TV it receives 1920x1080 12Bit with 120Hz:

It works with 4K 12Bit and 60Hz as well. Only 1440p for some reason only goes 8Bit no matter 120Hz or 30Hz.

[Beethy]

What are you all on about? I have the LG CX so this might be a C9 issue but I can play the game perfectly in HDR at 60fps 4k with DLSS.

No chroma subsampling.
Using Nvidia colour settings. RGB. Full. 8 bpc.
TV must have black levels set to high at RGB full.

It looks spectacular.
