Here’s How:

1. Most monitors will degauss automatically when turned on so as a first option, power off and then on your monitor. If the discoloration does not improve, continue to the next step.

Note: Degaussing makes a twang sound and is often followed by a short click sound. If you don’t hear these sounds, the monitor probably does not automatically degauss when powered on.

2. In the rare case the monitor does not automatically degauss, locate the degauss button on the front of the monitor. The button will most likely be accompanied by a picture similar to a horseshoe.Some monitors do not have a single button but instead require the simultaneous pressing of multiple buttons, such as the brightness and contrast buttons.
3. Often times the degauss option will be buried in the on-screen menu options. Scroll through these options to locate the degauss option or consult the monitor’s manual for more information.

Tips:

1. To prevent the magnetic field disturbances that cause the discoloration on the monitor, check around the monitor for sources of magnetism. This might include unshielded speakers, power sources, and of course magnets.
2. Monitors without a CRT, such as LCD monitors, do not require degaussing.

Here’s How:

1. Check the cable between the monitor and the computer to make sure it is secure. Each end should be tightly fastened.
2. Degauss the monitor. This will often help correct discoloration issues near the edges of the screen.
3. Reference the monitor manufacturer’s instructions to adjust the brightness and contrast settings. If available, you may also need to adjust the color balance and temperature settings.
4. Adjust the color quality setting for the video card. This will often help resolve issues where the colors, especially in photos, appear incorrect.
5. If you have access to another monitor, try it in place of the one with the color issues. If the problem goes away replace the monitor. If the problem duplicates on the new monitor there is most likely an issue with the video card.
