[Bug 1376581] Re: DisplayPort monitor not properly detected via HP ultraslim docking station 2013
Elitebook 840 G1 here with HP 2013 UltraSlim-Docking Station.
I was able to connect and recognize the monitor via Docking Station,
however the graphics are flickering and mouse seems to freeze when
moving fast.
Also there are problems when dragging windows to the sides of the screen
for resizing - windows keep jumping to other screens, instead of
sticking to the needed one.
On the other monitor, which is connected via DP of the laptop,
everything works fine.
