Monitors

A PC monitor, or personal computer monitor, is an electronic visual display for computers. A monitor usually comprises the display device, circuitry, casing, and power supply. The display device in modern monitors is typically a thin film transistor liquid crystal display (TFT-LCD) or a flat panel LED display, while older monitors used a cathode ray tube (CRT). It can also be a projector.

Monitors are connected to the computer via VGA, DVI, HDMI, DisplayPort, Thunderbolt, or a proprietary connector.

A monitor is an output device that displays information in pictorial form. CRTs and LCDs are the two most common types of monitors in use today.

CRTs use an electron beam to draw an image on a phosphor-coated screen. The image is then magnified and projected onto a screen. CRTs are bulky, and the image on the screen is blurry.

LCDs use a backlight and liquid crystals to display an image. LCDs are thin and lightweight and produce a clear image. However, they are more expensive than CRTs.

Most monitors today use LCD technology.
