Brand new Dell XPS12 with Super Speed docking station, running Windows 8.
I have a 22" LG monitor connected to the docking station's HDMI port.
Everything is fine until I lock my computer (Win+L).
When I unlock it, I can see the login screen just fine, but as soon as I enter the password, I only see a couple of squares here and there from my desktop. The rest still displays the login screen and it flickers...
Any idea why?
