Has anyone been able to get the dvi-out to work on the MBP under vista? I have a LCD television with vga/dvi in and wanted to connect the MBP to it. This works fine in OS X (Leopard), but just does not work in Vista and I can't figure out why. I have it connected via VGA at the moment, as I don't have a DVI cable. When Vista boots, the Windows startup progress bar does display on the external display, but once it actually gets into vista the external display goes black. Vista even popped up and said it detected the external display, and asked how I wanted it used, I chose Mirrored. I've gone to the Windows Mobility Center and made sure "External Display" was connect, which it was ("Displays connected"). Am I missing something here?
