QXGA

QXGA (Quad eXtended Graphics Array) is a display resolution of 2048×1536 pixels with a 4:3 aspect ratio. The name comes from the fact that it has four times as many pixels as an XGA display, but the abbreviation could also mean Quantum eXtended Graphics Array, a name given because (hyperbolically) the pixels of such a high resolution monitor would be so small they would have to be measured on the quantum scale. As of 2005, there are very few devices that can render images at such high resolution. A related display size is WQXGA, which is a wide screen version.
