Short for Video Graphics Array, VGA is a popular display standard developed by IBM and introduced in 1987, VGA provides 640 x 480 resolution color display screens with a refresh rate of 60Hz and 16 colors displayed at a time. If the resolution is lowered to 320 x 200, 256 colors can be displayed. VGA capability is built into plug-in video cards, VGA chips, and monitors that can work with the VGA cards. Today, VGA has been replaced by SVGA. The VGA/SVGA port, like that shown in the picture is also becoming obsolete and being replaced by the DVI port and connection.
Below is an illustration of the 15-Pin VGA connector, its pin assignments, and size dimensions with a chart describing what each of the pins are for.
