VGA

Video Graphics Array (VGA) is an analog computer display standard first marketed in 1987 by IBM. It has been technologically outdated in the PC market for some time.

VGA was the most recent graphical standard that the majority of manufacturers conformed to, making it the lowest common denominator that all PC graphics hardware supports before a device-specific driver is loaded into the computer. For example, the Microsoft Windows splash screen appears while the machine is still operating in VGA mode, which is the reason that this screen always appears in reduced resolution and color depth.

VGA refers to a resolution of 640×480, regardless of the hardware that produces it. Most commonly, however, VGA is referred to the 15-pin D-subminiature connector which is still widely used to carry analog video signals of all resolutions.

A VGA connector is a three-row 15-pin connector.  The 15-pin VGA connector is found on many video cards, computer monitors, and some high definition television sets.

VGA connector is also conventionally called RGB connector, D-sub 15, mini sub D15, mini D15, DB-15, HDB-15, HD-15 or HD15.

VGA connectors and cables carry analog component RGBHV (red, green, blue, horizontal sync, vertical sync) video signals, and VESA Display Data Channel (VESA DDC) data.
