WXGA, Wide XGA(Wide Extended Graphics Array)
Wide XGA (WXGA) is a group of non defined resolutions derived from the XGA display standard by widening it to a wide screen aspect ratio. WXGA is generally understood to refer to a resolution of 1366×768, with an aspect ratio of 16:9. In 2006 this was the most popular resolution for liquid crystal display televisions and HD ready plasma flat panel displays.
When used speaking of laptop displays or monitors intended primarily as computer displays, WXGA is most commonly used to refer to a resolution of 1280×800 pixels with an aspect ratio of 16:10.This resolution is particularly popular for most laptops with a 14" or 15" screen. The exact resolution this refers to is somewhat variable, however, as the 1280xnnn resolutions were among the first widescreen resolutions commonly used, and term entered use (especially for laptop displays) prior to the broad standardization 16:10 for widescreen computer displays.
Overall, several resolutions have been labeled as WXGA. These are the most common resolutions given the label (in ascending order by total number of pixels):
- 1280×720
- 1280×768
- 1280×800
- 1360×768
- 1366×768
1280×720 provides perfectly square pixels at an aspect ratio of 16:9, while the additional pixels in 1280×768 and 1280×800 must be ignored to give the 16:9 ratio without vertical stretching of the image. 1360×768 and 1366×768 come very close to 16:9, displaying exactly square pixels if 1360×765 pixels of the display are used.
