SXGA is an abbreviation for Super eXtended Graphics Array referring to a standard monitor resolution of 1280 × 1024 pixels. This resolution of 1,310,720 pixels is an enhancement of the standard XGA resolution that IBM developed in 1990.

This resolution is not the standard 4:3 aspect ratio but rather is 5:4. A standard 4:3 monitor using this resolution will have rectangular rather than square pixels, distorting the picture and causing circles to appear elliptical.

SXGA is the most common resolution on 17", 18" and 19" desktop LCD monitors. The majority of these monitors have a physical 5:4 aspect ratio, avoiding any distortion (e.g. the Samsung SyncMaster 172T, which measures 335x275mm displayable).

Apple Computer referred to displays with this resolution as "two-page displays", because they could be used to display two A4 pages side-by-side at a resolution of 72 DPI. Sony manufactured a 17" CRT monitor with a 5:4 aspect ratio designed for this resolution. It was sold under the Apple brand name.

A resolution of 1280 × 960 is also often supported, which has the standard 4:3 ratio.

A variation is SXGA+ which is 1400 × 1050 common on notebooks circa 2004.
