Dell 7480 Display issue after unlocking when docked
I'm having an issue with the contents of application windows when unlocking a docked (dual display) Dell 7480 laptop, whereby the application windows appear blank after unlocking the laptop. The OS (Win 7) is stable, and a reboot fixes it.
I have updated all drivers via the Dell website, and also the BIOS, but the issue remains. I've moved the HDD into another laptop, same problem.
I have also tried different monitors/cables, all to no avail.
Any help greatly appreciated.

I am also experiencing this issue with a 7480 while using a D6000 dock. All drivers and BIOS updated as well. I found a temporary solution was to change the windows theme to Aero from the personalize menu. However the theme seems to revert back to the default after a reboot. Any help would be greatly appreciated.
