Yes. Logs are attached (for CAC-1080 connected to docking station, at
1920x1080/60Hz resolution).

With the CAC-1080, high resolutions (3840x2160/60Hz) do not work via docking
station. The symptoms seem to me like there is some problem with signal
quality. (The display switches between "no signal" and a black screen with
strange detected resolution like 3840x2159 or 1920x2160. Sometimes a broken
picture shows briefly, sound can often be heard shortly.)
I am not sure if it is possible these issues are related (i.e. weak signal
causing different problems), or if should I open a separate bug for the video
issue?</pre>
