Worse yet, is your screen distorted or “messed up” in some way? Are text or images, or everything, blurry or moving by themselves? Your computer’s screen is the main way you interact with it, so any minor issue can quickly become a significant one.
How to Fix Discoloration and Distortion on a Computer Screen
There are several reasons why your monitor might distort images or represent color improperly, resulting in whatever specific issue you see, so let’s walk through some troubleshooting until we figure it out. That said, if you’re still using a CRT screen and the discoloration issues are focused near the edges of the screen, degaussing will most likely fix the problem. Here’s how to tell:
Replace the monitor when you try another monitor in place of the one you have, and the problems go away. Assuming you tried the other steps above and weren’t successful, there’s little if any reason to think the problem is due to something else. Replace the video card when, after testing with a different monitor and other cables, the problem does not go away. Another confirmation that it’s the video card is seeing the problem before Windows starts, like during the initial POST process.
