Updated: 10/30/2017 by Computer Hope

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 60 Hz and 16 colors displayed at a time. If the resolution is lowered to 320 x 200, 256 colors are shown.

VGA utilizes analog signals, which means it is only capable of lower resolutions and lower quality display on screens.
