What is the function of a computer monitor?

The monitor is an essential part of the overall computer system. It is sometimes referred to as the video screen or video display unit (VDU).

There are two main types of computer monitors:

Cathode Ray Tube (CRT) monitors utilize a cathode ray tube to display images. The cathode ray tube is constructed using a vacuum tube, heaters, electron guns, deflection circuits and a glass screen. When electrons are produced within the cathode ray tube, the screen is bombarded with electrons, making it glow and produce an image. CRT monitors resemble older television sets. They are bulky and consume a lot of energy.

Liquid Crystal Display (LCD) screens utilize monochrome pixels when projecting images. The pixels are arranged systematically between transparent electrodes and polarizing filters. Images are formed when the pixels are polarized. LCD monitors consume less energy and offer better graphics quality. They are outselling CRT monitors because they occupy less desk space, provide wide viewing angles and are decreasing in price. The screen sizes range from 17 inches to 60 inches.

How to enter the BIOS or CMOS setup?

Because of the wide variety of computer and BIOS manufacturers over the evolution of computers, there are numerous ways to enter the BIOS or CMOS Setup. Below is a listing of most of these methods, as well as other recommendations for entering the BIOS setup. ⚠ Note: Apple, or Mac, computers do not have a BIOS and instead utilize an EFI, which does not need to modified based on the hardware in the computer, like a BIOS. The EFI provides better integration between hardware and software for Apple computers, virtually eliminating the need for a BIOS. ⚠ Note: This document does not help if you cannot enter the CMOS setup with password. New computers Computers manufactured in the last few years allow you to enter the BIOS setup using one of the five keys shown below during the boot process. ⇾ F1 ⇾ F2 * ⇾ F10 ** ⇾ DEL ⇾ ESC * If pressing F2 opens a diagnostics tool, your setup key is likely F10 ** F10 is also used for the boot menu. If F10 ...
