Windows 8 cannot use extended display
Hey all. I just upgraded my Lenovo laptop (T430) to windows 8, and I'm having a crazy time trying to get the extended display to work properly off the dock. Whenever I switch to extended, it ends up turning off hte display on the laptop itself, and the external monitor flashes on the lower part of the screen. I have updated my video drivers to the windows 8 version and can work just fine off of the laptop itself. Any advice on how to get this to work properly?
