I have a MBP 2009 and can't get a picture on my Vizio HDTV when connected and its in Windows mode..w/ Snow Leopard its fine and automatically connects but not with Windows. I should mention I have Windows XP on my Mac, not Vista or 7. This is driving me crazy. Even if I'm in Snow Leopard on my Mac and its connected, when I switch on the Mac to Windows, the HDTV goes blank...or blue rather, saying no connection. Any help is highly appreciated. Obviously this is something w/ Windows and hope someone could shed some light on the subject. Thanks!
