Monitor

Monitors are of two types, Cathode Ray Tube (CRT) and flat panel Liquid Crystal Device (LCD). Monitors gather dust quickly due to static charge generation. Therefore, the outer case and screen require regular cleaning. The correct way to clean the monitor depends on the type of monitor:
	CRTs: Use a cloth dampened with water or a mild window cleaning solution to wipe the glass screen and clean the monitor case. Alternatively, you can use moistened paper towels to clean them. Do not spray any liquid directly on the screen. Never open the monitor case which contains electric voltage that can cause a shock.
	LCDs: Use a soft, dry cotton cloth or a small amount of isopropyl alcohol with dampened cloth to remove finger prints and smudges from an LCD screen. To avoid any damage, do not use paper towels, sharp objects, and strong cleaners such as ammonia to clean an LCD screen.


	Note
Gas Plasma: Another popular monitor type is Gas Plasma. Gas Plasma display is a type of flat display screen, called a flat-panel display. It is used in some portable computers. Images on gas plasma displays generally appear as orange objects on a black background. Although gas plasma displays produce very sharp monochrome images, they require much more power than the more common LCD displays. Static Charge is generated between materials through friction, pressure, or separation of two materials. One material out of the two materials is generally non-conductive.
