I'm using my Samsung q70 tv as a pc monitor and I would like to get YCbCr420 changed to RGB and dynamic range set to full instead of limited. I can do this only if I change HDMI input from 1 to 4, which is the gaming input. The problem is when I shut down my computer and TV and start them up again, my TV won't recognize that there is computer in HDMI 4 input. When I change it to HDMI 1 port and start TV and computer again it works.
I have brand new RTX 3070 GPU so the problem is not that I don't have good enough pc specs.
Appreciate all your help, thanks!I want RGB and full range
