- XGA+
XGA+ stands for eXtended Graphics Array Plus and is a
computer display standard . XGA+ is often used on 17 inch desktop CRT monitors. XGA+ is usually understood to refer to the 1152×864 resolution with an aspect ratio of 4:3. AsLCD screens are getting increasingly popular, this resolution is decreasing in use, but it is the native resolution of some 17 inch LCD displays.Historically, the resolution relates to the earlier standard of 1152×900 pixels, which was adopted by
Sun Microsystems for theSun-2 workstation in the early 1980s. This resolution is close to the maximum practical which, using onebyte perpixel , can fit into a video memory or frame-buffer of onemegabyte . However, its aspect ratio is 3.84:3. WhenApple Computer defined a standard resolution for 21-inch CRT monitors, intended for use as Two-Page Displays on theMacintosh II computer, Apple selected instead 1152×864, which is the highest 4:3 resolution below one million pixels.XGA+ is the next step after XGA (1024×768), although it's not approved by any standard organizations. The next step with an aspect ratio of 4:3 is 1280×960 ("SXGA-") or SXGA+ (1400×1050).
