Outputting 2560x1440@60 works fine, outputting 3840x2160@60 produces no picture on external monitor.

When removing the onelink prodock and connecting the dp cable directly to the laptop then all resolutions works (3840x2160@60).

Whenever running xrandr it adds 36 lines to kernel log of 'The master control interrupt lied'
