The eXtended Graphics Array (usually called XGA) is a graphics card manufactured by IBM and introduced for the IBM PS/2 line of personal computers in 1990 as a successor to the 8514/A. It supports, among other modes, a display resolution of 1024 × 768 pixels with 256 colors at 43.5 Hz ( interlaced ), or 640 × 480 at 60 Hz ( non-interlaced ...
Some EGA monitors are switchable, meaning that they can be set up to use the full palette even in 200-line modes, often through a mechanical switch. Only a few commercial games were released with support for the extended color palette in 320 × 200 or 640 × 200 (including the DOS version of Super Off Road ).
However, IBM sold the companion CRT monitor (for use with the 8514/A) which carries the same designation, 8514. The 8514 uses a standardised API called the "Adapter Interface" or AI. This interface is also used by XGA , IBM Image Adapter/A , and clones of the 8514/A and XGA such as the ATI Technologies Mach series and IIT AGX .
Wide XGA (WXGA) is a set of non-standard resolutions derived from XGA (1024 × 768) by widening it to 1366 × 768 [104] [105] [106] with a widescreen aspect ratio of nearly 16:9 or to 1280 × 800 [103] with an aspect ratio of 16:10. WXGA is commonly used for low-end LCD TVs and LCD computer monitors for widescreen presentation.
On Linux and DOS systems with so-named SVGA cards, a program called SVGATextMode [34] can be used to set up better looking text modes than EGA and VGA standard ones. This is particularly useful for large (≥ 17") monitors, where the normal 80×25 VGA text mode's 720×400 pixel resolution is far lower than a typical graphics mode would be.
A widely used de facto standard, introduced with XGA-2 and other early "multiscan" graphics cards and monitors, with an unusual aspect ratio of 5:4 (1.25:1) instead of the more common 4:3 (1. 3:1), meaning that even 4:3 pictures and video will appear letterboxed on the narrower 5:4 screens. This is generally the native resolution—with ...
Super VGA (SVGA) or Extended VGA is a broad term that covers a wide range of computer display standards that extended IBM's VGA specification. [ 1 ] [ 2 ] When used as shorthand for a resolution, as VGA and XGA often are, SVGA refers to a resolution of 800 × 600.
Extended Video Graphics Array (or EVGA) is a standard created by VESA in 1991 (VBE 1.2) [1] [2] [3] denoting a non-interlaced resolution of 1024x768 at a maximum of 70 Hz refresh rate.
