SXGA stands for Super Extended Graphics Array, a display resolution of 1280 x 1024 pixels. It is commonly used in computer monitors and projectors, providing a 5:4 aspect ratio. This resolution offers a clear and detailed image, making it suitable for various applications, including office work and gaming. Introduced in the late 1990s, SXGA was an improvement over the earlier XGA resolution of 1024 x 768 pixels. While newer resolutions like HD and 4K have become more popular, SXGA remains relevant for certain devices and applications that do not require higher pixel densities.
