Apple Display Connector




The Apple Display Connector ('''ADC''') is a proprietary modification of the DVI connector that combines analog and digital video signals, USB , and power all in one Cable . Apple used ADC for their flat panel LCD s and their final CRT display, before deciding to use "standard" DVI connectors on later models.

A setup using ADC dramatically reduces the Cable Spaghetti behind a computer. USB devices like the keyboard and mouse could be plugged into the display, the display into the host computer using ADC, and a single power cable to the wall from the computer. The result was effectively a single cable wiring the components together.

First implemented in the July 2000 Power Mac G4 and G4 Cube , ADC disappeared from displays in June 2004 when Apple introduced the aluminum-clad 20", 23", and 30" Cinema Displays, which feature separate DVI , USB and FireWire connectors, and their own power supply. The ADC connector was still standard on the Power Mac G5 until April 2005 , when new models meant the only remaining Apple product with an ADC connector was the single processor Power Mac G5 introduced in October 2004 . This single processor Power Mac G5 was discontinued soon after in June 2005 .

A DVI to ADC adapter for newer systems is currently available from Apple. It will take a separate USB, DVI, and power connection from the computer and combine them into an ADC connection. An ADC to DVI adapter is also available for users of ADC systems with a DVI display. On newer displays lacking ADC, Apple still attempts to clean up the cabling through the use of a "ganged cable" that connects the separate signal cables to each other so they cannot tangle.
