QXGA (Quantum Extended Graphics Array) is a display mode in which the resolution is 2048 pixel s horizontally by 1536 pixels vertically (2048 x 1536). This results in 3,145,728 pixels in the image (sometimes referred to as 3.2 million pixels).
A QXGA display might be preferred by computer users who want or need extreme detail, or who want to view multiple images on a single screen. 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 high-end image-editing program. Advanced projection systems use QXGA to obtain images that appear crisp even when enlarged to dimensions such as those used in presentations.
Liquid crystal display ( LCD ) panels with the QXGA specification can offer a level of detail comparable or superior to print on paper. The main disadvantage of this type of display is the high cost compared with displays having less resolution. Projection systems using QXGA technology typically cost upwards of USD$10,000.
