UXGA (Ultra Extended Graphics Array)

Contributor(s): Daniel Martini

UXGA (Ultra Extended Graphics Array) is a display mode in which the resolution is 1600 pixels horizontally by 1200 pixels vertically (1600 x 1200). This amounts to a total of 1,920,000 pixels on the screen.

A UXGA display might be preferred by computer users who want or need fine detail. UXGA displays also allow the user to specify up to four 800 x 600-pixel images at a time, with reasonable detail in each. An example of such an application is the reception of a television (TV) program while browsing the Web, and at the same time working in a word processor and a vector graphics program. Scientists and engineers can make use of the high resolution and large screen size when working with computer-aided graphics (CAD) programs, especially three-dimensional (3D) rendering.

A UXGA display provides 6.25 times as many pixels as a 640 x 480 display, four times as many pixels as an 800 x 600 display, and approximately 2.44 times as many pixels as a 1024 x 768 display. Modest-sized liquid crystal display (LCD) panels with the UXGA specification offer a level of detail comparable to print on paper. The main disadvantage of this type of display is the high cost compared with displays having less resolution.
