WSXGA Wide XGA+ WTF?
WSXGA and WXGA+ are non-standard terms referring to computer display resolutions. Usually, WSXGA refers to a resolution of 1680×1050, while WXGA+ refers to a resolution of 1440×900, but occasionally manufacturers use the terms to refer to other resolutions (for example, [1]). The Standards Panel Working Group refers to the 1440×900 resolution as WXGA(II)[2].
WSXGA and WXGA+ can be thought of as enhanced versions of WXGA with more pixels, or as widescreen variants of SXGA. The aspect ratios of each are approximately 16:10 (widescreen).
