I have tried various length/specs of HDMI cable, turning off HDR and switching to 4:2:2/4:2:0 color profiles in Nvidia Control Panel in an attempt to reduce bandwidth with no luck, and wondering if CRU can help but I don't know where to start.

Usually flickers like that indicate a signal quality issue, but if you've tried different cables, then either something is wrong with the TV or the port on the GPU, or some program running on your PC is causing this.

Was 144 Hz available before? Check the output color depth. Not all refresh rates might be available at 10/12 bpc.

i dm'ed u and i have now found out how to find the postes i have made on this platform, and yes 144hz is available, and i have the output color on the same as it always have been in the settings, and i have tried reset.exe and it still wont fix my issue

reset.exe doesn't exist. did you mean reset-all.exe or restart.exe?

Hey guys, I've asked everywhere else, but I forgot that this place is the best place to ask any questions regarding resolutions and etc.

I've just snagged a used LG B7 Oled in great condition, no retention or burn in. Just a tiny amount of pixels in the corner that fade to black once it heats up, which is probably an overheating issue that I could solve by taking the shell and getting a some fans or something.

So anyways, it's HDMI 2.0 only. I'm wondering what useful I can do with it.
I want to get 1440p/120hz, but when I enabled it through Nvidia panel HDR doesn't work properly, screen is overblown, darks are gray and I think it's stuck at only 8bit rgb.

What would be the best resolutions, colour depth and format for an OLED?
And how do I even change colour depth and format in CRU?

NVIDIA control panel custom resolutions are always RGB. You can try adding 2560x1440 @ 120 Hz with CRU and see if you get a different result. Color depth and formats are defined in the HDMI data blocks, but they are not resolution-specific except for 4:2:0, so you shouldn't need to change anything related to color formats in CRU.

Thanks. Really appreciate your work and dedication to the community behind it.

I've just tried it, I've cleared all custom resolutions in Nvidia control panel using NvCRBT as I couldn't delete them for some reason. Unistalled monitor driver in manager and restarted.

Set up a custom resolution in CRU 2560x1440 @ 120Hz using automatic HDTV and automatic native HDTV and both fail. LG tv shows invalid format on screen. Any idea?

Sorry to be bothersome.

What timing parameters did you use with the NVIDIA control panel? The same timing parameters should work with CRU.

I am unsure, because it was set to automatic in there as well.
Also I've tried changing it 120hz in nvidia panel again and it wasn't working. I've later realized that for some reason first I need to apply a 120hz profile. The highest one available is 1080p, so afterwards I edited resolution on that profile to 1440p and it works like it did before.

I've changed color settings to 4:2:2 8 bit, that's the only one working with HDR, at least I think it's working because it's not washed out. The rest have the washed out screen. It is the same on 1080P regular preset. HDR only works at 8 bit 4:2:2.

At native 4K/60 every single color profile and depth work fine, 4:2:2, 4:4:4, 4:2:0. No matter the depth, 8bit, 10bit, or 12bit.

How do I read timing parameters from Nvidia panel so I can apply them to CRU?
I don't think this is a cable issue as 4K60 with 4:2:0 12 bit would use up more bandwith than 4:2:2 8bit 1440/120 no?

That's not a true 2560x1440. You're scaling down to 1920x1080, which is then scaled up to 3840x2160 by the TV, so it's being scaled twice. The NVIDIA control panel shows the timing parameters when you create the custom resolution. The active pixels is what is actually sent to the display, so if the resolution at the top doesn't match the active pixels, it's being scaled by the GPU. Windows will also show you the desktop resolution vs. the active signal resolution in the advanced display settings. Based on what I've read from searching, the LG B7 doesn't support 2560x1440 @ 120 Hz, only 1920x1080 @ 120 Hz.
