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 ...
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 ...
This chart shows the most common display resolutions, with the color of each resolution type indicating the display ratio (e.g., red indicates a 4:3 ratio).
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.
If the monitor were connected to a CGA card, these pins would not carry valid color information, and the screen might be garbled if the monitor were to interpret them as such. For this reason, standard EGA monitors will use the CGA pin assignment in 200-line modes, so the monitor can also be used with a CGA card.

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 .
Ultima II, the first game in the game series to be ported to IBM PC, used CGA composite graphics. King's Quest I also offered 16-color graphics on the PC, PCjr and Tandy 1000, but provided a 'RGB mode' at the title screen which would utilize only the ordinary CGA graphics mode, limited to 4 colors. Examples of CGA games on RGBI and composite ...
