I'm going to be doing a presentation soon with powerpoint or keynote. Just wondering, are there any specific steps to connect my MBP to a projector? Do I need to install any software, or does plug n play do the work? These steps is what I have in my head right now, correct me if I'm wrong. 1.Plug in the DVI to VGA cord. 2. Plug in the VGA cord from the projector. And the projector is properly working. Thanks in advance!
