The Apple VGA Display Adapter was specially designed to allow users to connect an eMac, iMac G5, 12-inch PowerBook G4, or iBook to an extra VGA monitor or external projector (equipped with VGA) for 24-bit video-mirroring. The VGA cable plugs into the VGA video-out port built into your eMac, iMac flat panel, PowerBook G4 (12"), or iBook.
Important: Compatible only with eMac, iMac G5, iMac G4 flat-panel, 12-inch PowerBook, or iBooks having a VGA port. Certain iBook models may also have an A/V port for composite video-out. Use an Apple A/V Cable for composite video-out. The VGA cable is for VGA video-out only.
