I have a laptop with Windows 8 and a 22" monitor that I use simultaneously. If I start up, then connect the monitor via HDMI (using Intel HD3000 graphics) I can set up an extened desktop no problem. However when I next turn on the computer, leaving the cable plugged in, my laptop display stays blank. The Intel control panel and Windows control panel both agree that it's there, and I can drag windows there, but it stoically refuses to turn on.
Has anyone else had this, and/or know what to do about it?
