What is XGA?

Short for Extended Graphics Array (XGA), XGA was introduced in 1990 and is an update to IBM’s VGA video standard. XGA is a computer display standard that provides a resolution of 1024 by 768 pixels in 256 colors or 640 by 480 pixels in 16-bit color. This is an IBM proprietary standard that was originally intended to replace the earlier VGA (Video Graphics Array) standard, but as it was quickly replaced by better technology, it became simply known as part of the VGA family instead (with other formats such as SVGA and UVGA).
