What is WXGA?

WXGA is "wide" XGA, a non-standard resolution derived from the XGA, or Extended Graphics array, standard introduced by IBM in the 1990s - the hardware of which was developed in the UK (for an enumeration of computer display standards see wikipedia). WXGA uses a "widescreen" aspect ratio (ratio of long side to the short side of a display unit).

Metrics for WXGA hardward include luminance in "nits" (an American term for candela per square meters (cd/m^2)); the word derives from the latin nitere (to shine). An average cloudy sky is about 2000 nits, an average laptop screen is about 10 % of that at 200 nits. The moon's surface is about 2500 nits, over ten times brighter than the average laptop screen.

Luminance is also known as luminous intensity or photometric brightness.
