How to Degauss a Monitor ?

[Simran]

Hello , I Have an Samsung Crt monitor , when i Was setting it resolution in the Main Menu i Found out that it had a option of Degaussing it , Can you What does it mean to "degauss" a monitor? and How can i Do ? Does Degaussing affect the monitor screen in anyway Thanks in Advance For Your replies

Degaussing a computer monitor clears electromagnetic buildup from the screen. Although it is hardly ever necessary, degaussing can sometimes slightly improve picture quality.

Simply turn the monitor off and turn it back on. Most modern monitors degauss themselves automatically each time they are powered on. When the monitor is turned on, you should hear a distinctive "dwoing" sound. If you hear no sound when you turn the unit on, it may not degauss itself automatically. If that is the case, proceed to the next step.Look for a button labeled DEGAUSS. This may be combined on an EXIT buttonOtherwise, locate the menu button on the front of the monitor. Bring up the on-screen menu, locate the degauss option (the ohm icon), and select it. You should now hear the degaussing noise, and the screen will probably display a brief burst of color.

Degaussing is the process of decreasing or eliminating an unwanted magnetic field. It is named after Carl Friedrich Gauss, an early researcher in the field of magnetism. Due to magnetic hysteresis it is generally not possible to reduce a magnetic field completely to zero, so degaussing typically induces a very small "known" field referred to as bias.

To remove 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. You can also use an external degausser that degausses the monitor from the outside. Since it may be impossible to remove the external magnetic force, degaussing works by re-aligning the magnetic fields inside the CRT to compensate for the external magnetism.

You can also degauss magnetic media, such as disks, which removes all data from the media.

Hello , Degaussing Can be Done in Crt monitor only becuase The technology used to create the picture in an LCD display, flat panel display, laptop, and any other non CRT monitor is not the same. Therefore there is no degaussing option available for these displays.
