AudioVision 14 Display
Introduced in August 1993, the AudioVision 14" Display was Apple's first "multimedia" VDU (Visual Display Unit). Not only did it feature a 14" Sony Trinitron tube, but also a built-in set of speakers, microphone, ADB hub, and a power port useful for the Apple QuickTime Conferencing Cam 100. Initially, all buyers of AudioVision monitors also had to buy the adaptor to use it with the standard Macintosh video port; except those whom owned Power Macintosh 6100, 7100 and/or 8100 computers, all of which had the required HDI45 ports installed on the motherboard.
The AudioVision 14" Display is a fixed-sync monitor that displays at a resolution of 640×480 with a refresh rate of 67 Hz.
In 2000, Apple reintroduced a similar display cabling technology, ADC, which carried power for the display, a digital video signal, and USB over one cable from the computer to the VDU.
