Hello,
I have 2 amd videcards, AMD RX 460, and AMD Vega 200GE (integrated). With both of them LE outputs YCbcr limited.
How can I change it to full RGB 4:4:4 ?
Im trying to find solution for a long of time, but still nothing. My linux undesrtanding is highly limited. Could someone help pls?
Here's what xrandr --verbose does show, doesn't seem to have necessary option
