SVGA and VGA Cable Tutorial
SVGA Defined

Super Video Graphics Array, aka Super VGA or SVGA, is a broad term that covers a wide range of computer display standards. Originally, it was an extension to the VGA standard. Unlike VGA, a purely IBM-defined standard, Super VGA was defined by the Video Electronics Standards Association (VESA), an open consortium developed to promote interoperability and define standards. When used as a resolution specification, in contrast to VGA or XGA for example, the term SVGA normally refers to a resolution of 800x600 pixels, but was quickly extended to 1024x768 8-bit pixels and beyond.


The number of colors was defined in the original specification, but became irrelevant as the interface between the video card and VGA or SVGA monitor uses simple analog voltages to indicate the desired color depth.  There is no limit to the number of different colors that can be displayed. While the output of a VGA or SVGA video card is analog, the internal calculations the card performs are entirely digital.


The original SVGA was to be succeeded by Super XGA, but the industry abandoned the attempt to provide a unique name for each higher display standard; almost all display systems made until the early 2000s were classed as Super VGA. SVGA uses the same High-Density 15-pin D-Subminiature connector (HD15) as the original standard.
