I am using Kubuntu 20.04, nvidia driver 440.82.
I have some subtle color banding issues on my generic 1080 led monitor (IPS panel). This is not very noticeable problem really, but still annoying to my eyes. I can only notice it in some unfocused backgrounds of my RAW photos.
But in summary, that color banding is more visible in RGB color space mode selected from nvidia settings (DVI-d, HDMI). But this is corrected if I choose YCbCr444 color space mode (HDMI).
The problem is that I want to use PRIME On-Demand mode, but nvidia settings doesn’t show Monitor settings with PRIME and I can’t select Color Spaces modes when PRIME is used.
Is this because when using PRIME, color space modes depends on intel iGPU drivers?
How could I choose YCbCr444 color space for my HDMI monitor when I use PRIME?
