Most Common Widescreen resolutions

Overall, many 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.
720p, the HDTV video mode, is a related standard, measuring 1280×720 pixels.

What is XGA Widescreen Resolution?

Wide XGA (WXGA) is a set of non standard resolutions derived from the XGA display standard by widening it to a widescreen aspect ratio. WXGA is commonly used for low-end LCD TVs and LCD computer monitors for widescreen presentation.

If we want to talk about televisions and other monitors intended for consumer entertainment use, 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 while XGA was for Plasma TVs flat panel displays.

If we want to talk about 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.
