Public bug reported:
4k support of my Lenovo X250 with and without docking station does not work.
Ubuntu offers 4k resolution but my display keeps black.
I can reproduce this bug with Dell P2415Q and Dell P2715Q connected via Mini
DisplayPort and DisplayPort (Dock).
The most recent 16.04 build fails the same way.
Thanks!
