Monitor

A monitor is a device that displays visual information from a computer or other electronic device. Monitors are an essential part of a computer system, even though they are external to the computer case. A monitor is an electronic output device used to display information being entered and processed on a computer. The primary use of a monitor is to display images, text, video, and graphics information generated by the computer via a computer's video card.

How does a monitor work?
  • A monitor displays a two-dimensional array of colors on a screen. 


  • The quality of the visual output is determined by the monitor's resolution, refresh rate, and color display capabilities. 


  • A monitor is connected to a computer via a cable that plugs into a port on the computer's video card or motherboard. 


Types of monitors
  • Cathode-ray tube (CRT): The original type of monitor, invented by Karl Ferdinand Braun in 1897. 


  • Liquid crystal display (LCD): A more modern type of monitor that uses a glass panel filled with liquid crystal material. 


  • Organic light-emitting diode (OLED): A newer type of monitor that uses organic LEDs to offer better color accuracy and faster pixel response times.
