You can connect displays with Mini DisplayPort or Digital Visual Interface (DVI)
connectors to the display ports on the back of your Mac Pro. The DVI port is a dual-link
port, so you can connect a 30-inch Apple Cinema HD Display.
You can also connect displays that have an Apple Display Connector (ADC) or a video
graphics array (VGA) connector using one of the following adapters:
 To connect a VGA display to the DVI port or the Mini DisplayPort, use the Apple DVI
to VGA Display Adapter or the Apple Mini DisplayPort to VGA Adapter (both available
separately).
 To connect an ADC display to the DVI port, use an Apple DVI to ADC Display Adapter
(available separately).
Display adapters and other accessories for your Mac Pro are sold separately at
