UXGA
From Wikipedia, the free encyclopedia
UXGA is an abbreviation for Ultra eXtended Graphics Array referring to a standard monitor resolution of 1600 × 1200 pixels, which is exactly quadruple the default resolution of SVGA (800 × 600). Dell Computer refers to the same resolution of 1,920,000 pixels as UGA. It is generally considered to be the next step above SXGA (1280 × 960 or 1280 × 1024), but some resolutions (such as SXGA+ 1400 × 1050) fit in between the two.
UXGA is the native resolution of most 20" and 21" desktop LCD monitors, and also of some 15" 4:3 laptop LCDs (such as the ones in Thinkpad A31p, T42p, and T43p). Several 14" laptop LCDs with UXGA also exist, but these are very rare.
There is a widescreen version of UXGA called WUXGA with a resolution of 1920x1200.
