So far Windows 8 installs fine and runs well on an external display outputted from my 2011 MacBook Air. But my Air's screen looks like the attachement. The bottom half is mirrored and constantly flickers. I've tried all the different available resolutions and refresh rates with no success. I'm guessing its a Intel HD 3000 driver issue. Strange because the Thunderbolt out works fine. Any other air users have the same problem?
