The Apple DVI to ADC Adapter allowed any Apple flat-panel display using an Apple Display Connector (ADC) to be used with any computer with a DVI port. The device included a power supply, power cord, and DVI/USB cable. Apple described the capabilities of the adapter:
“It has been carefully designed to maintain the digital integrity of the video signal for the best possible viewing experience. The adapter provides an all-digital signal path between the computer and the display. It features active components that regenerate both the digital graphics and USB signals coming from the computer. This ensures delivery of the highest-quality images even at the extremely fast signal rates used by the Apple Cinema HD Display.”
The purpose of the Apple Display Connector (ADC) was to reduce display cables. ADC combined DVI, power, and USB in a 30 pin (3 x 10) connector. ADC was used between 2000–2004. The primary issue with the proprietary ADC connection was that it carried power to the display (DVI does not), thus, a typical adapter was not possible. Instead, this adapter was relatively large because it included a power supply, measuring about 5 x 5 x 1.5 inches. It was also expensive for an adapter, selling for $99 when it was released.
Mac models that could use the Apple DVI to ADC adapter included Power Mac G4 (Mirrored Drive Doors, 2002–2003), Power Mac G5 (June 2003–Late 2005), PowerBook G4 15-inch (DVI, 2002–Double Layer SD, 2005), PowerBook G4 17-inch (2003–Double Layer SD, 2005), MacBook Pro 15-inch (Early 2006–Early 2008), MacBook Pro 17-inch (Early 2006–Late 2008), Mac mini (Early 2005–Mid 2007), and Mac Pro (Early 2006–Mid 2012).
