Step 3: Hold the degaussing coil near the monitor’s screen and move it in a circular motion, starting from the center of the screen and moving outwards.

Step 4: Move the coil back to the center of the screen and repeat the process.

Step 5: Turn on the monitor and check if the picture quality has improved.

Automatic Degaussing

Most modern monitors have an automatic degaussing feature that runs every time the monitor is turned on. However, if you feel the picture quality is still unsatisfactory, you can manually degauss the monitor.

To activate the automatic degaussing feature, follow these steps:

Step 1: Turn on the monitor and let it warm up for a few minutes.

Step 2: Press the degauss button on the monitor. The button’s location may vary depending on the model of the monitor.

Step 3: Wait for a few seconds while the monitor degausses automatically.

Step 4: Check if the picture quality has improved.

More About Degaussing & How To Prevent It

Degaussing is demagnetizing an object, such as a computer monitor or hard drive, to erase magnetic data or eliminate magnetic interference. While degaussing is necessary for maintaining the picture quality of a CRT monitor.
