Im migrating from youttube to try and resolve this
The monitor is advertising colorspaces it doesn’t support in it’s EDID. Do you have a model? Can you upload the EDID file to [hub.libre.computer]-and we can patch it for you? Run this in a terminal: cp $(find /sys/ -iname edid | grep HDMI) edid
I did this and got:
/sys/kernel/debug permission denied
pstore permission denied
bpf permission denied
Im sorry i am bad at this stuff.
