Video Graphics Array. Video Graphics Array ( VGA) is a video display controller and accompanying de facto graphics standard, first introduced with the IBM PS/2 line of computers in 1987, [ 1][ 2][ 3] which became ubiquitous in the IBM PC compatible industry within three years. [ 4] The term can now refer to the computer display standard, the 15 ...
Each screen character is represented by two bytes aligned as a 16-bit word accessible by the CPU in a single operation. The lower (or character) byte is the actual code point for the current character set, and the higher (or attribute) byte is a bit field used to select various video attributes such as color, blinking, character set, and so forth.

IBM 8514, Video Graphics Array. The Enhanced Graphics Adapter ( EGA) is an IBM PC graphics adapter [ 2][ 3] and de facto computer display standard from 1984 that superseded the CGA standard introduced with the original IBM PC, and was itself superseded by the VGA standard in 1987. In addition to the original EGA card manufactured by IBM, many ...
A graphics card (also called a video card, display card, graphics accelerator, graphics adapter, VGA card/VGA, video adapter, display adapter, or colloquially GPU) is a computer expansion card that generates a feed of graphics output to a display device such as a monitor. Graphics cards are sometimes called discrete or dedicated graphics cards ...
ATI Wonder series. The ATI Wonder is a series of video cards for the IBM Personal Computer and compatibles, introduced by ATI Technologies in the mid to late 1980s. [ 1][ 2][ 3] These cards were unique at the time as they offered the end user a considerable amount of value by combining support for multiple graphics standards (and monitors) into ...
Video Graphics Array. Successor. XGA. Super VGA ( SVGA) is a broad term that covers a wide range of computer display standards that extended IBM's VGA specification. [ 1] When used as shorthand for a resolution, as VGA and XGA often are, SVGA refers to a resolution of 800 × 600. [ 2]
An extension to VGA defined by VESA for IBM PC-compatible computers in 1989 meant to take advantage of video cards that exceeded the minimum 256 kB defined in the VGA standard. For instance, one of the early supported modes was 800×600 in 16 colours at a slightly lower 56 Hz refresh rate, leading to 800×600 sometimes being referred to as ...
The Hercules Graphics Card ( HGC) is a computer graphics controller formerly made by Hercules Computer Technology, Inc. that combines IBM 's text-only MDA display standard with a bitmapped graphics mode, also offering a parallel printer port. [ 1][ 2] This allows the HGC to offer both high-quality text and graphics from a single card.
