How to Fix Discoloration and Distortion on a Computer Screen

Most of these are easy things to try, but a few of these tasks might be more difficult or unfamiliar than others. If so, take your time and be sure to reference any instructions on other pages if you need extra help.

1. Power off the monitor, wait 15 seconds, and then power it back on. Some issues, especially very minor ones, can be caused by very temporary issues with your computer’s connection that a restart will fix.
   If the problem goes away but quickly returns, especially if it’s color-related, try leaving the screen off for 30 minutes before powering it back on. If that helps, your monitor may be suffering from overheating.
2. Restart your computer . There’s a slight chance that an operating system issue is the cause of the discoloration or distortion, and a simple restart will do the trick. Restarting is an easy thing to try early in the troubleshooting process. Plus,restarting seems to fix most computer problems .
3. Check the cable between the monitor and the computer to make sure that_each end_ is physically secure. Completely unplug, and plug back in, each end to be sure.
   Newer interfaces, likeHDMI , often “push” in and “pull” out, meaning gravity can sometimes eventually work them loose from both the monitor side and the computer side. Older interfaces likeVGA andDVI are often screw-secured, but they come loose sometimes, too.
4. Degauss the monitor . Yes, this is very much some “throwback” advice, considering that magnetic interference, which degaussing corrects, only happens on those large CRT monitors of yesteryear.
   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.
5. Using your monitor’s adjustment buttons or onscreen settings, find the preset default level and enable it. This preset should return your monitor’s many settings to “factory default” levels, correcting any color issues caused by settings.
   If you have an idea about what’s “off” with your colors, feel free to manually adjust individual settings like the brightness, color balance, saturation, or temperature, etc., and see if that helps.
   If you’re not sure how to do any of this, reference your monitor’s instruction manual.
6. Adjust the color quality setting for thevideo card . Setting it at the highest level possible will often help resolve issues where the colors, especially in photos, appear incorrect.
   Fortunately, newer versions of Windows only support the highest color options possible, so this is probably a worthwhile thing to look into only if you’re using Windows 7, Vista, or XP.
7. At this point, any significant discoloration or distortion problem you’re seeing on your monitor is probably due to a physical problem with either the monitor itself or the video card.
   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 initialPOST process .
