I'm using the internal laptop screen and 2 external monitors - the problem
appears only with the one connected via an USB-C to HDMI adapter.
- The setup works flawlessly on Windows (using the same resolution and refresh
rate)
- I've managed to get it working on Ubuntu only once by randomly switching
(using Gnome settings & xrandr) screen resolutions, refresh rates, "Broadcast
RGB"=Full setting - I cannot reproduce the exact sequence, it got broken again
after a restart
