SVGA (super video graphics array)

A video display standard that offers greater resolution and colour depth than VGA. The resolution (clarity and sharpness) of an image is determined by the number of pixels that can be displayed per square inch. Colour depth is determined by the number of colours (from 256 to 16 million) that can be displayed simultaneously. The number of both pixels and colours is limited by the amount of video memory on the SVGA system. See also pixel.
