Short for
extended graphics array, a
high-resolution graphics standard introduced by
IBM in 1990. XGA was designed to replace the older
8514/A video standard. It provides the same resolutions (640 by 480 or 1024 by 768
pixels), but
supports more simultaneous colors (65 thousand compared to 8514/A's 256 colors). In addition, XGA allows
monitors to be
non-interlaced.
