Your computer probably has a “VGA or SVGA monitor” that looks a lot like a TV but is smaller, has a lot more pixels and has a much crisper display. The CRT and electronics in a monitor are much more precise than is required in a TV; a computer monitor needs higher resolutions. In addition, the plug on a VGA monitor is not accepting a composite signal — a VGA plug separates out all of the signals so they can be interpreted by the monitor more precisely. VGA is the only video standard that can be found on nearly all PC architecture.

First introduced by IBM, the Video Graphics Array was an enhancement to EGA and CGA, two earlier types developed by Big Blue. Later SVGA was introduced by the Video Electronics Standards Association.
