Full DVI is built into the MacBook Pro, with a DVI - VGA adapter included in the box.
Mini DVI is for iMacs and MacBooks
yeah i know, pjarvi said to buy a "mini-DVI cable for an external monitor" when MBPs use full DVI.
so if the external monitor has a full DVI cable like my cinema display you dont need to use the DVI-VGA adapter. and if the external monitor has a VGA cable you use the DVI-VGA adpater included with the macbook pros.
