What I also noticed is that in SDR the gamma curve is different (darker) in pc-mode even when using the exact same settings as in non-pc mode.

So I'm back to standard hdmi input mode. Getting 444 chroma on this TV seems to be impossible without some major issues.
So you are back to RGB 8bit full for both SDR and HDR content or you switch to RGB 12bit full @23Hz for HDR?

What chain did end up using:? graphics card->madVR->TV ?
