WUXGA stands for Widescreen Ultra eXtended Graphics Array and is a display resolution of 1920×1200 pixels (2,304,000 pixels) with a 16:10 screen aspect ratio.

It is a wide version of UXGA, and is appropriate for viewing HDTV content. These formats use a 1920×1080 image at a 16:9 ratio, which is displayed well on WUXGA – the image is slightly letterboxed, but maintains aspect ratio. Since the display is slightly larger than the corresponding 1080 HD source, the video can play at native resolution with no scaling required; the extra 60 lines above and below the image are simply unused.

The 16:10 aspect ratio (as opposed to the 16:9 used in widescreen televisions) was chosen because this aspect ratio is appropriate for displaying two full pages of text side by side.[1] It also allows viewing of 16:9 video on a computer with player controls visible. The 16:10 screen (and display device profile) also comes very close to a golden rectangle, which is often considered the most aesthetically pleasing.

WUXGA resolution is equivalent to 2.3 megapixels. An 8-bit RGB WUXGA image has an uncompressed size of around 6.6 MiB.

This resolution is currently available in high-end LCD televisions and computer monitors, the latter of which are typically in the size range of approximately 23"–28" for desktop monitors and on notebook monitors in the size range of 15.4"-18.4" since at least 2003. A small number of 22" WUXGA desktop monitors exist (i.e., Lenovo L220x, and Samsung T220P). WUXGA use predates the introduction of LCDs of that resolution. Most QXGA displays support 1920×1200 and widescreen CRTs such as the Sony GDM-FW900 and Hewlett Packard A7217A do as well.

The next lower resolution (for widescreen) before it is WSXGA+, which is 1680×1050 pixels (1,764,000 pixels, or 30.61% fewer than the WUXGA); the next higher resolution widescreen is an unnamed 2304×1440 resolution (supported by the above GDM-FW900 & A7217A) and then the more common WQXGA, which has 2560×1600 pixels (4,096,000 pixels, or 77.78% more than the WUXGA).

There are two wider formats called UWXGA 1600x768 (25:12) and UW-UXGA that has 2560x1080 pixels, a 2.39:1 or 21:9 aspect ratio.
