xorg log


My RX 560 won't do 4k 60hz over HDMI. I have tested the cable/display with a
different PC (that has a 1080Ti) and it works fine, so I can confirm that both
the cable and the TV are capable of displaying a 4k 60hz signal. I have also
tested with a monitor that is capable of doing 4k 60hz over HDMI.

xrandr only shows 30hz as an option on both the TV and the monitor.
