General
Do you want to connect your iMac or MacBook to an external VGA screen or projector? Then Apple has the solution in the form of the Mini DVI-to-VGA adapter! Simply connect the Mini DVI plug to the Mini DVI port on your Mac computer and then connect the VGA connector to an external VGA screen or projector.
Synchronous & comprehensive playback
This adapter supports both synchronous and comprehensive playback. Synchronous playback allows you to display everything you see on your Apple computer screen on an external screen. With comprehensive playback, you can use the external screen as an expansion of your computer, so you can divide different windows over multiple screens. This is definitely the cable you need if you want to watch a film on the projector or give a PowerPoint presentation on your iMac!
