How to Degauss a Computer Monitor

Degaussing is the process of removing the magnetic field that builds up on a computer monitor over time. This magnetic field can cause distortion and color issues on your screen, which can be frustrating to deal with. Fortunately, degaussing a computer monitor is a relatively simple process that can be done in just a few steps. In this article, we will discuss how to degauss a computer monitor and answer some frequently asked questions about the process.

What is Degauss?

Degaussing is the process of reducing or eliminating the magnetic field that builds up on electronic devices such as computer monitors, television screens, and hard drives. Over time, these devices can develop a magnetic field that can cause distortion, color issues, and other problems. Degaussing is accomplished by using a magnetic field to neutralize the built-up magnetic field on the device. The process is usually done using a degaussing coil or through the degaussing button on the device itself.

How to Degauss a Computer Monitor:

Step 1: Turn off the Monitor

The first step in degaussing your computer monitor is to turn it off. This is an essential step because it allows the magnetic field to dissipate before you begin the degaussing process.

Step 2: Locate the Degaussing Button

Most modern computer monitors have a degaussing button located on the front of the monitor. This button is usually labeled with the word “degauss” or a small magnet symbol. If you can’t find the button, consult the monitor’s user manual for instructions on how to degauss the monitor.

Step 3: Press the Degaussing Button

Once you have located the degaussing button, press it. You will hear a buzzing sound as the monitor degausses itself. This process usually takes a few seconds to complete.

Step 4: Power on the Monitor

After the degaussing process is complete, you can turn your monitor back on. You should notice that the colors on your screen are now more accurate, and there is no distortion.


How often should I degauss my computer monitor?

A: It depends on how often you use your monitor and how susceptible it is to magnetic fields. If you use your monitor for long hours every day and it is located near other electronic devices, you should degauss it every two to three weeks. If you use it less frequently, you can degauss it once a month.

Can I use a magnet to degauss my monitor?

A: No, you should never use a magnet to degauss your monitor. Magnets can cause permanent damage to your monitor and should be avoided at all costs. Only use the degaussing button on your monitor or consult a professional if you need to degauss your monitor.

What are the signs that my monitor needs to be degaussed?

A: If you notice distortion or color issues on your monitor, it may be time to degauss it. Other signs include a wavy or blurry screen or a lack of sharpness in the images on your screen.

Can I degauss my monitor myself, or do I need to hire a professional?

A: You can degauss your monitor yourself using the degaussing button on the front of the monitor. If you are not comfortable doing this, or if you have an older monitor that does not have a degaussing button, you may need to hire a professional to degauss your monitor.

Will degaussing my monitor fix all issues?

A: No, degaussing your monitor will only fix issues related to the magnetic field on your monitor. If you are experiencing other issues, such as a damaged screen or hardware problems, degaussing will not fix these issues.


Degaussing your computer monitor is an important maintenance task that can help keep your monitor functioning properly. By following the simple steps outlined in this article, you can degauss your monitor quickly and easily. Remember to degauss your monitor regularly to prevent issues with distortion and color accuracy. If you have any questions or concerns about degaussing your monitor, consult a professional for assistance.
