| The image and table detail the 15-pin VESA DDC2/E-DDC connector; the diagram's pin numbering is that of a female connector functioning as the graphics adapter output. In the male connector, this pin numbering corresponds with the cable's wire-and-solder side. | |||
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, as well as many monitors, projectors and HD television sets.
Other connectors have been used to carry VGA-compatible analog RGB signals, such as mini-VGA, including those which predate VGA, such as BNC and DE-9, but "VGA connector" typically refers to this 15-pin design.
Once a ubiquitous presence, some devices do continue to be manufactured with VGA connectors, but newer digital interfaces such as DVI, HDMI, and DisplayPort (sometimes via USB or Thunderbolt) have largely displaced VGA, and modern computers and other devices do not typically include it any longer.
