WUXGA
From Wikipedia, the free encyclopedia
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 North American HDTV content (ATSC) and 1080p high-definition movies on Blu-ray Disc. 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 an appropriate 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 what is considered an aesthetically pleasing, golden rectangle.
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 15.4"-17" on notebook monitors.
The next lowest 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 highest resolution widescreen is WQXGA, which has 2560×1600 pixels (4,096,000 pixels, or 77.78% more than the WUXGA).
