Table of Computer Display Standards

A number of common resolutions have been used with computers descended from the original IBM PC. Some of these are now supported by other families of personal computers. These are de-facto standards, usually originated by one manufacturer and reverse-engineered by others, though the VESA group has co-ordinated the efforts of several leading video display adapter manufacturers. Video standards associated with IBM-PC-descended personal computers include:

Video StandardFull NameDescriptionDisplay Resolution (pixels)Aspect RatioColor Depth (2^bpp colors)
unnamed Various Apple Inc., Atari, Commodore PCs introduced from 1977 to 1982. They used TVs for their displays and typically included a 32x40 wide border in the overscan region of the television, with a usable space of only 320x200 or 160x200 or 80x200 (approximately). They used progressive scan to provide a stable image.352×240p

MCGAMulticolor Graphics AdapterIntroduced on selected PS/2 models in 1987, with reduced cost compared to VGA. MCGA had a 320x200 256 color (from a 262,144 color palette) mode, and a 640x480 mode only in monochrome due to 64k video memory, compared to the 256k memory of VGA.320×200

VGAVideo Graphics ArrayIntroduced in 1987 by IBM. VGA is actually a set of different resolutions, but is most commonly used today to refer to 640 × 480 pixel displays with 16 colors (4 bits per pixel) and a 4:3 aspect ratio. Other display modes are also defined as VGA, such as 320 × 200 at 256 colors (8 bits per pixel) and a text mode with 720 × 400 pixels. VGA displays and adapters are generally capable of Mode X graphics, an undocumented mode to allow increased non-standard resolutions.720×400

XGA+Extended Graphics Array PlusAlthough not an official name, this term is now used to refer to 1152 x 864, which is the largest 4:3 array yielding under one million pixels. Variants of this were used by Apple Computer (at 1152x870) and Sun Microsystems (at 1152x900) for 21-inch CRT displays.1152×864

SXGASuper XGAA widely used de facto 32 bit Truecolor standard, with an unusual aspect ratio of 5:4 (1.25:1) instead of the more common 4:3 (1.33:1), which means that 4:3 pictures and video will appear letterboxed on the narrower 5:4 screens. This is generally the physical aspect ratio & native resolution of standard 17" and 19" LCD monitors.
  • Some manufacturers, noting that the de facto industry standard was VGA (Video Graphics Array), termed this the Extended Video Graphics Array or XVGA.
