In its simplest sense, a VGA (Video Graphics Array) port is a high density d-sub 15-pin three rows connector, D-subminiature style port usually located on the back or side of a laptop computer or the back of a desktop system. Users employ VGA ports to transfer analog video signals from one machine to another using VGA cables. The arrangement of the 15 pins on the VGA port is in three groups of five pins, lined up horizontally.
Abbreviated VGA, Video Graphics Array is a standard type of connection for video devices such as monitors and projectors.
Generally, VGA refers to the types of cables, ports and connectors used to connect monitors to video cards.
The port is the “female” version of the pair, meaning it appears as a series of holes, while the cable is the “male” version with the appropriate pins. VGA ports first appeared in 1987 and are analog components capable of carrying red, green, blue, horizontal sync, and vertical sync (RGBHV) video signals.
