Good to know, thanks.

I'm going to look into a 4K HDMI switch that will allow me to plug the PC
and AVR into it and switch the UHD 4K at 60 between the two. That way I can
let the PC run at 4K @60 i.e. leave it in auto mode and let the apps change
the resolution as needed. I can solve the Desktop issue with the DPI
setting in xorg.conf.
