==Compatibility==

The Apple Display Connector is physically incompatible with a standard DVI connector.

On some models of Power Mac G4 the ADC connector replaced the DVI connector. This change necessitated a passive ADC to DVI adapter to use a DVI monitor.

The ADC carries up to 100 W of power, an insufficient amount to run most 19-inch (48 cm) or bigger CRTs widely available during ADC's debut, nor can it run contemporary flat panels marketed for home entertainment (many of which support DVI or VGA connections) without an adapter. The power limit was an important factor for Apple to abandon ADC when it launched the 30-inch (76 cm) Apple Cinema HD Display.

On newer DVI-based displays lacking ADC, Apple still opted for a single "[[octopus cable|ganged cable]]" that connects the separate signal cables to each other so they cannot tangle. Such cables, however, employ standard DVI, power, USB and FireWire connectors, avoiding drawbacks to ADC. Beginning in 2008, Apple began transitioning away from DVI, adopting the increasingly common [[DisplayPort]] signalling standard, and developed their own [[Mini DisplayPort]] connector beginning with the first LED-backlit Cinema Displays. As of 2013, Apple no longer uses a DVI-based interface for any of its displays.

Apple no longer supports ADC adapters or monitors.
