Editing Pixel (section)

===Resolution of computer monitors===
Computer monitors (and TV sets) generally have a fixed [[native resolution]]. What it is depends on the monitor, and size. See below for historical exceptions.

Computers can use pixels to display an image, often an abstract image that represents a [[GUI]]. The resolution of this image is called the display resolution and is determined by the [[video card]] of the computer. [[Flat-panel monitor]]s (and TV sets), e.g. [[OLED]] or [[LCD]] monitors, or [[electronic paper|E-ink]], also use pixels to display an image, and have a [[native resolution]], and it should (ideally) be matched to the video card resolution. Each pixel is made up of [[triad (monitors)|triads]], with the number of these triads determining the native resolution.

On older, historically available, [[cathode-ray tube|CRT]] monitors the resolution was possibly adjustable (still lower than what modern monitor achieve), while on some such monitors (or TV sets) the beam sweep rate was fixed, resulting in a fixed native resolution. Most CRT monitors do not have a fixed beam sweep rate, meaning they do not have a native resolution at all – instead they have a set of resolutions that are equally well supported. To produce the sharpest images possible on a flat-panel, e.g. OLED or LCD, the user must ensure the display resolution of the computer matches the native resolution of the monitor.
