| Super Video Graphics Array |
A video display standard created by VESA for IBM PC compatible personal computers. the resolution is 800x600 4-bit pixels. Each pixel can therefore be one of 16 Colors.
The phrase 'Super VGA' technically means 800x600 resolution, at 16 Colors. This standard was set by the VESA group in the early days of VGA. Today, modern VGA Video Interface Cards offers at least 1,024 by 768 resolution, and some go to 1280x1024 or even higher. The main limiting factor is the amount of Video RAM available to the Video System and the number of Colors required at these extended resolutions.
