WXGA Definition

WXGA (Wide XGA) is a high resolution, wide aspect ratio electronic display standard that supports a resolution of 1366 to 1280 pixels horizontally by 768 to 720 pixels vertically and an aspect ratio of 16:9.

A pixel (a contraction of picture element) is one of the many tiny dots that make up the representation of a picture on a display screen. Resolution is the amount of detail that an image contains, and higher resolutions are made possible by greater numbers of pixels. The aspect ratio is the ratio of image width to image height.

XGA (extended graphics array) was introduced by IBM in 1990 as a replacement for the older 8514/A video standard. Although it provides the same resolutions (i.e., 640 by 480 and 1024 by 768 pixels), it supports far more simultaneous colors (65,000 compared to 8514/A's 256), and it allows monitors to be non-interlaced.

The 16:9 aspect ratio contrasts with the 4:3 aspect ratio of most computer monitors, i.e., 640 by 480 pixels for VGA, 800 by 600 for SVGA and 1600 by 1200 dots for UXGA. 4:3 is also the aspect ratio of the NTSC television standard which is used in the U.S., Japan and some other countries.

WXGA is commonly used for wide screen LCD computer monitors and televisions and for wide screen projection systems.
