The VESA Enhanced Video Connector (EVC) is a VESA standard that was intended to reduce the number of cables around a computer by incorporating video, audio, FireWire and USB into a single cable system, terminating in a 35-pin Molex MicroCross connector. The intent was to make the monitor the central point of connection.
Applies to V.35–V.39. V.35 is an ITU-T standard located on layer 1 on the OSI model. Max speed is 2 Mbit/s and synchronous only. Withdrawn ITU-T recommendation for 48 kbit/s data transmission over wideband circuits. The physical and electrical characteristics of this interface are now specified in ITU-T recommendation V.11.
The Video Graphics Array (VGA) connector is a standard connector used for computer video output. Originating with the 1987 IBM PS/2 and its VGA graphics system, the 15-pin connector went on to become ubiquitous on PCs, [1] as well as many monitors, projectors and HD television sets.
The data is transmitted via the cable connecting the display and the graphics card; VGA, DVI, DisplayPort and HDMI are supported. [ citation needed ] The EDID is often stored in the monitor in the firmware chip called serial EEPROM (electrically erasable programmable read-only memory) and is accessible via the I²C-bus at address 0x50 .
Perhaps the most comprehensive known and most discussed feature of ANSI/TIA-568 is the definition of the pin-to-pair assignments, or pinout, between the pins in a connector (a plug or a socket) and the wires in a cable. Pinouts are critical because cables do not function if the pinouts at their two ends aren't correctly matched.
Pin 1 is typically indicated on the body of the connector by a red or raised "V" mark. The corresponding wire in a ribbon cable is usually indicated by red coloration, a raised molded ridge, or markings printed onto the cable insulation. On the connector pin 2 is opposite pin 1, pin 3 is next to pin 1 along the length of the connector, and so on.

The plug or male connector are shown, as visible when unplugged; female sockets are mirror images Several non-standard sockets are designed to mate with standard mini-DIN plugs. These connectors provide extra conductors and are used to save space by combining functions in one connector that would otherwise require two standard connectors.
