The Apple VGA cable was specially designed to allow users to connect an e Mac, i Mac flat panel, Power Book G4 (12" TFT display), or i Book 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 e Mac, i Mac flat panel, Power Book G4 (12"), or i Book. Important: Compatible only with e Mac, i Mac, Power Book (12") or i Books having a VGA port. Certain i Book 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.
