Monitors are peripheral devices that visually display text and graphics output from a computer or other source. They may include special features such as doubling as a television, or having multi-displays.
Monitor displays may be classified as monochrome (displays one color and black), grey-scale (varying shades of black and white) or color (RGB).
Monitors are available in several different types which look similar to a television but are capable of higher resolutions:
CRT (Cathode Ray Tube) are the traditional bulky tube monitors. They have high brightness and are able to display high resolutions at a lower price.
Flat panel LCD (Liquid Crystal Display) models are lightweight, thin monitors which save on desk space and electricity, at a higher cost. They are available in larger sizes than CRT screens. LCD monitors are also available in touchcreen versions which perform as input devices, by touching specific areas on a ressure-sensitive screen.
Plasma displays use plasma technology and can be used as a presentation display or television set. They are the lightest monitor per size, with the smallest depth, which make them especially suited for wall-mounting.
CRT monitors (cathode ray tube) are the traditional television-like computer display screens. CRT monitors will provide good resolution and color range. They also have a wider viewing angle compared to LCD screens.
CRT monitors are priced lower than LCD screens, so if the larger bulk and weight are not considerations, and if they will not need to be moved often, CRT screens are more affordable per size.
Thin, lightweight LCD (liquid crystal display) monitors are a good choice where less desk space is available. Although more expensive per screen size, LCD monitors use less electricity than CRTs which will save on energy bills.
LCD monitors have the best display at their native resolution, while CRTS can display multiple resolutions with equal quality. Newer LCD monitors are equal, however, in terms of brightness and color range.
