Like the title says. I have two of the same monitor (both 4k 60Hz) with both using DisplayPort cables and yet one of them is being locked into 30Hz. This is only happening on Debian. On Windows and Pop_OS it correctly has both monitors doing 4k 60Hz.
Xrandr output:Any idea why 60.00 would be missing for DP-2? I've already tried the following:
xrandr --addmode DP-2 3840x2160_60.00
to which it complains "Cannot find mode "3840x2160_60.00"". Any idea what I'm doing wrong?
