What is a monitor for a PC?

A monitor is an output device that displays video images and text. It is made up of circuitry, a screen, a power supply, buttons to adjust screen settings, and casing that holds all of these components.

Monitors come in two major types, LCD and CRT

1)   CRT (Cathode Ray Tube)

Cathode ray tube, a CRT is the electron beams in a monitor moving across your screen either interlaced or non-interlaced, hitting phosphor dots inside the glass tube.

In 1934, the first CRT televisions were made available commercially in Germany by Telefunken.

2)   LCD (Liquid-Crystal Display)

AMD and Intel, with a handful of computers monitor manufacturers, announced they were phasing out support for VGA starting in December 2010.

NEC was one of the first companies to manufacture LED monitors for desktop computers. Their first LED monitor, the MultiSync EA222WMe, was released in late 2009.

Touch screen LCD monitors started to become cheaper, more affordable for the average consumer in 2017. Prices for 20 to 22-inch touch screen monitors dropped below $500.
