How To Degauss the Monitor

Degaussing is a method used to improve the overall picture quality of any display device that uses Cathode Ray Tube (CRT) technology. Degaussing removes distortions in images and color on a television or computer monitor by introducing a source of sufficient electromagnetic force to get rid of magnetism that has built up due to prolonged use.

  1. Use the automatic degauss function. Most display devices such as televisions or computer screens have a built in mechanism that automatically does the degaussing process whenever the device is switched on. The easiest way to degauss your computer monitor would be to turn it off and on again. Just locate the monitor's power button that is typically positioned in the bottom right part of the monitor. Notice that when you do this, you will hear a quick swooshing sound that indicates the monitor has been degaussed. 
  2. Manually degauss. If you didn't hear any distinctive sound while doing Step 1, then most likely the monitor doesn't have an automatic degauss system. If so, look for the menu button on the bottom of the monitor and select the degauss icon, which is usually an image of a horseshoe magnet. Once you select it, the degaussing process should commence with a distinctive noise and sometimes a sudden burst of colors. If you can't find the degauss function, then holding down the contrast and brightness buttons at the same time should do the trick.
  3. Introduce magnet taped on a drill. Securely tape a magnet onto an electric drill's end. Afterwards, position the contraption about a couple of inches away from the monitor. Run the drill by pulling its trigger. A sudden blurring of the monitor will happen which will indicate that the degaussing has been performed. Finally, slowly pull the contraption away from the monitor. It is important to note that this process should only be done if Steps 1 and 2 have already been done. 
  4. Use an electric fan. If you have a small and handy table top electric fan, then it might just help you with your monitor's problems. Hold the fan in front of the monitor. Make sure that the back part of the fan is the one that's facing the monitor. Afterwards, just turn the fan on. The magnet in the fan's dynamo should give off considerable magnetism to degauss your monitor. Again, do this process if manual or automatic degaussing processes described in steps 1 and 2 did not prove to be helpful.

Degaussing is rarely necessary. However, if performing the steps outlined above has not been useful, then probably your monitor is of an older model that might just need to be replaced.
