he VESA Enhanced Video Connector is a VESA standard intended to reduce the number of cables around a computer by incorporating video, audio, FireWire, and USB into a single cable system. The intention of the system was to make monitor the central point of connection. Although the specific idea did not find favor with computer manufacturers, it was evolved into the somewhat more popular VESA Plug and Display standard.
A VESA EVC connector is capable of carrying analog video (VGA-based) output, video input (composite), FireWire, audio (analog stereo), and USB signals. The pinout is somewhat similar to the newer VESA Plug and Display. It can be distinguished from a Plug and Display connector by the shell, which is shaped like an isosceles trapezoid similar to the shell of a D-subminiature instead of the "D"-shaped shell of a DVI connector.
