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 LCDs and their final CRT display, before deciding to use Digital Video Input (DVI).

An ADC display accepts only digital input signals. As such, the appropriate connector can only be used with a graphics card which provides digital output. This connector does not support connections from graphics adapters providing Analog-only (VGA) output.

A monitor using an ADC connector can be directly connected to a graphics card which provides an ADC output. Additionally, an ADC monitor may be connected to a graphics card providing a DVI-I or DVI-D output when used with a third party adapter. DVI to ADC adapters should be available directly from Apple or from most local Apple-Authorized Dealers.
