Weird. The XorgLog shows that HDMI is talking to the wrong driver so I
assumed that meant it is plugged into the wrong GPU...
Does your computer not have multiple HDMI ports? If not then it looks
like there's a problem with how the Nvidia driver is installed here.
- or -
The modeset driver might be refusing high bandwidth modes prematurely?
[ 18.036] (--) modeset(0): HDMI max TMDS frequency 300000KHz
[ 18.036] (II) modeset(0): Not using default mode "3840x2160" (bad mode
clock/interlace/doublescan)
[ 18.036] (II) modeset(0): Not using default mode "2560x1440" (bad mode
clock/interlace/doublescan)
