Super Video Graphics Array or Ultra Video Graphics Array, almost always abbreviated
to Super VGA, Ultra VGA or just SVGA or UVGA is a broad term that covers a wide
range of computer display standards. Originally, it was an extension to the VGA standard
first released by IBM in 1987. Unlike VGA—a purely IBM-defined standard—Super
VGA was defined by the Video Electronics Standards Association (VESA), an open
consortium set up 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 800 × 600 pixels.
