So I have a dual screen set up at home. A 20" Widescreen Dell Monitor and the internal MacBook 13" screen. For some reason, I can't seem to connect the External monitor to my MacBook via Mini Display Port -> VGA. It just doesn't work. It works in OSX, I can use both monitors but in Vista, I can only use the Internal Screen or clamshell external screen. Does anyone have this problem? I've tried connecting the wire and restarting and to no use.
