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 ...
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.
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.
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 ...
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 .
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).
1080p progressive scan HDTV, which uses a 16:9 ratio. Some commentators also use display resolution to indicate a range of input formats that the display's input electronics will accept and often include formats greater than the screen's native grid size even though they have to be down-scaled to match the screen's parameters (e.g. accepting a 1920 × 1080 input on a display with a native 1366 ...
