Abbreviation for Video Graphics Array. VGA is a graphics display system for PCs developed by IBM, and has become one of the de facto standards for PCs. In text mode, VGA systems provide a resolution of 720 by 400 pixels. In graphics mode, the resolution is either 640 by 480 (with 16 colors) or 320 by 200 (with 256 colors). The total palette of colors is 262,144. Since its introduction in 1987, several other standards have been developed that offer greater resolution and other advantages, but VGA remains the lowest common denominator. All PCs made today support VGA, and usually some other more advanced standard.
