Various computer display standards or display modes have been used in the history of the PCs. They are often a combination of resolution (specified as the width and height in pixels), colour depth measured in bits, and refresh rate expressed in Hertz.

Current standards

  • UXGA - Ultra XGA. An unofficial standard with a resolution of 1600 x 1200 with 32 bit pixels, true colour.
  • SXGA - Super XGA. An unofficial standard with a resolution of 1280 x 1024 with 32 bit pixels, true colour.

Older standards

  • XGA - Extended Graphics Array is an IBM display standard introduced in 1990. XGA supports a resolution of 1024 x 768 pixels with a palette of 256 colours, or 640 x 480 with high colour (16 bits per pixel). XGA-2 added 1024 x 768 support for high colour and higher refresh rates, improved performance, and supports 1360 x 1024 in 16 colours.
  • SVGA - Super Video Graphics Array. A video display standard created by VESA for IBM PC compatible personal computers. The resolution is 800 x 600 4-bit pixels. Each pixel can therefore be one of 16 colours.
  • VGA - Video Graphics Array, with 640 x 480 pixels in 16 colours and a 4:3 aspect ratio. There is also a text mode with 720 x 400 pixels.
  • 8514
  • EGA - Enhanced Graphics Adapter, with a resolution of 640 x 350 pixels of 16 colours.
  • CGA - One of IBM's earliest hardware video display standards for use in IBM PCs. CGA can display 80 x 25 or 40 x 25 text in 16 colours, 640 x 200 pixels graphics in 2 colours or 320 x 200 in 4 colors (IBM PC video modes 0-6).
  • Hercules, A monochrome display with resolution of 720 by 348 capable of text and graphics.
  • MDA, monochrome display adapter, the original standard on IBM XT PCs. Supports text only at 720 by 350 pixels.
