Degauss???

Question

the computers at my school have this function, degauss, what does it do? It makes the screen blur and colorfull for a sec, but whats its purpose?

Answer 1

It's a term use to describe the process of removing magnetism from a device. The term is usually used in reference to color monitors and other display devices that use a Cathode Ray Tube (CRT). These devices aim electrons onto the display screen by creating magnetic fields inside the CRT. External magnetic forces -- such as the earth's natural magnetism or a magnet placed close to the monitor -- can magnetize the shadow mask, causing distorted images and colors.
To remove this external magnetic forces, most monitors automatically degauss the CRT whenever you turn on the monitor. In addition, many monitors have a manual degauss button that performs a more thorough degaussing of the CRT.>>>>Although it's not a good idea to use the degauss button frequently because it will shorten the monitor life. Use it only when you need to.

Answer 2

It demagnetizes the picture tube. All CRT monitors and TV picture tubes do this automatically during startup. Some monitors, usually higher end monitors will have the deguass button. Have you ever felt the static on a Picture tube when you started it? This is what causes it.

Answer 3

It takes away excess magnetism that can effect the components of older computers.

Answer 4

It fixes damage caused by magnetic influences.

Go stick the fridge magnet on the TV for a while and see what it does.

(Just kidding, dont do it)
