(listed most recent on top)

  • 16:10
    • QUXGA-Wide
      Widescreen Quad Ultra XGA: 3840 2400, with a 16:10 aspect ratio. Also known as WQUXGA. This resolution generally requires 2 DVI connections between the monitor and graphics card.
    • WUXGA
      Widescreen Ultra XGA: 1920 1200, with a 16:10 aspect ratio.
    • WSXGA+
      Widescreen Super XGA+: 1680 1050, with a 16:10 aspect ratio.
    • WXGA+
      Widescreen XGA+: 1440 900, with a 16:10 aspect ratio. WXGA+ can also refer to 1200 854, which is a 3:2 aspect ratio.
    • WXGA
      Widescreen XGA: can refer to 1440 900 or 1280 800, both with a 16:10 aspect ratio, or to 1280 768 with a 5:3 aspect ratio.
  • 16:9
    • 1080i/1080p
      HDTV resolutions that some monitors accept, they are 1920 1080 pixels with a 16:9 aspect ratio. The resolutions are used with interlaced (1080i) or progressively-scanned (1080p) video.
    • 720i/720p
      HDTV resolutions of 1280 720 and aspect ratio 16:9, either interlaced (720i) or progressively-scanned (720p). These resolutions work with many multisync SXGA displays, though the video will appear horizontally squeezed if the vertical range of the scan beam is not changed.
  • 4:3 (Displayed aspect ratio. Some standards utilize non-square pixels)
    • QUXGA
      Quad Ultra XGA: 3200 2400 pixels. This resolution generally requires 2 DVI connections between the monitor and graphics card.
    • QXGA
      Quad XGA, quad meaning four, so the display has four times the pixel amount of XGA, with 2048 1536 pixels. Also called Super Ultra XGA (SUXGA).
    • UXGA
      Ultra XGA, a de facto standard with a resolution of 1600 1200 with 32 bit pixels, true color.
    • SXGA+
      Super XGA+, 1400 1050.
    • SXGA
      Super XGA, a de facto standard with a resolution of 1280 1024 with 32 bit pixels, true color. This is an unusual resolution because the numbers work out for a 5:4 display rather than a 4:3 one, so many images appear wider on SXGA displays than most other resolutions. The resolution probably should have been 1280 960 (a popular standard resolution for Unix workstations).
    • XGA+
      XGA+, 1152 864.
    • XGA
      Extended Graphics Array is an IBM display standard introduced in 1990. XGA supports a resolution of 1024768 pixels with a palette of 256 colors (8 bits per pixel), or 640480 with high color (16 bits per pixel). XGA-2 added 1024 768 support for high color and higher refresh rates, improved performance, and supports 1360 1024 in 16 colors (4 bits per pixel).
      • 8514
        Precursor to XGA and released about the same time as VGA. 8514/A cards had a maximum resolution of 1024 768 with 256 colors (8 bits per pixel), interlaced at 43.5 Hz.
    • SVGA
      Super VGA, a video display standard created by VESA for IBM PC compatible personal computers. The resolution is 800 600 4-bit pixels. Each pixel can therefore be one of 16 colors.
    • VGA
      Video Graphics Array 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.
      • MCGA
        Multicolor Graphics Array. Precursor to VGA, MCGA introduced a 256 color (from a 262,144 color palette) mode, and a 640x480 resolution mode. However, whereas VGA had 256k of video memory, MCGA only had 64k, and was limited to black and white at 640x480 and limited to 320x200 for 256 color operation.
    • QVGA
      Quarter VGA
    • EGA
      Enhanced Graphics Adapter, with a resolution of 640 350 pixels of 16 different colors (8 bits per pixel) selectable from a 64-color palette (10 bits per palette item).
    • CGA
      Color Graphics Adapter, developed in 1981, IBM's first color graphics card for IBM PCs. CGA can display 80 25 or 40 25 text in 16 colors (4 bits per pixel), 640 200 pixels graphics in 2 colors (1 bit per pixel) or 320 200 in 4 colors (2 bits per pixel) (IBM PC video modes 0-6).
    • Hercules
      a monochrome display with a resolution of 720 348, capable of sharp text and graphics. Very popular with the Lotus 1-2-3 spreadsheet, which was the PC's first killer app.
    • MDA
      Monochrome Display Adapter, the original standard on IBM PCs and IBM PC XTs. Supports text mode only at 720 350 pixels.
