XGA (1024×768)
XGA, the Extended Graphics Array, is an IBM display standard introduced in 1990. Later it became the most common appellation of the 1024×768 pixels display resolution, but the official definition is broader than that. It was not a new and improved replacement for Super VGA, but rather became one particular subset of the broad range of capabilities covered under the "Super VGA" umbrella.
The initial version of XGA expanded upon IBM's VGA, adding support for two resolutions:
800×600 pixels with high color (16 bits per pixel; i.e. 65,536 colors).
1024×768 pixels with a palette of 256 colors (8 bits per pixel)
Like its predecessor (the IBM 8514), XGA offered fixed function hardware acceleration to offload processing of 2D drawing tasks. XGA and 8514 could offload line-draw, bitmap-copy (bitblt), and color-fill operations from the host CPU. XGA's acceleration was faster than 8514's, and more comprehensive in that it supported more drawing primitives and XGA's 16 bits per pixel (65,536 color) display-mode.
XGA-2 added Truecolor mode for 640×480, high color mode and higher refresh rates for 1024×768, and improved accelerator performance. All XGA modes have a 4:3 aspect ratio rounded to 8 pixels.
XGA should not be confused with EVGA (Extended Video Graphics Array), a contemporaneous VESA standard that also has 1024×768 pixels.

WUXGA (1920×1200)
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 can be used for viewing high-definition television (HDTV) content, which uses a 16:9 aspect ratio and a 1920×1080 resolution.
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.[19]
WUXGA resolution is equivalent to 2.304 megapixels. An 8-bit RGB WUXGA image has an uncompressed size of 6.912 MiB. This was the highest resolution that was commonly available in the computer display industry until the release of the Retina MacBook Pro in 2012. However, outside the 17" MacBook pro, its use had been almost completely ended by 2010 as the rest of the computer industry moved to the 16:9 aspect ratio (i.e., 1920×1080 is the highest resolution available from most laptop and computer monitor manufacturers besides Apple). This resolution is currently available in a few high-end LCD televisions and computer monitors, the latter of which are typically in the size range of approximately 23"–28" for desktop monitors, but has become almost completely unavailable on non-Apple notebook monitors. 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 WUXGA).
There are two wider formats called UWXGA 1600×768 (25:12) and UW-UXGA that has 2560×1080 pixels, a 2.37:1 or 21⅓:9 or 64:27 aspect ratio, sometimes erroneously labeled 21:9.
