All LCD monitors have hundreds of thousands of pixels, each made up of three color cells. It is rare for every cell in every pixel to be working properly. Monitor manufacturers have a minimum number of dead and stuck pixels that each of their monitors can have, even when they are brand new. If your monitor is no longer under warranty or your manufacturer won't support the number of pixels you have problems with, there are still solutions. Read on to learn fix a stuck pixel on an LCD monitor.
Instructions
1. Identify your pixel problem. A stuck pixel is one where one or more of the cells is stuck on (so you have a bright, oddly colored, point of light) or off (you have an oddly dark spot). A dead pixel that no longer works will appear as a black spot.
2. Try running pixel fixing software. This method is the safest for the health of your monitor so it should always be the first thing you attempt. There are several pixel testing programs out there and most of them are free. The software will rapidly turn pixels on and off. Cycling through the various colors very rapidly will sometimes "unstick" the pixels and fix the problem.
3. Memorize the location of the pixel and turn off your monitor. Using a pointed, but dull, object (such as a screwdriver) poke your monitor gently at the point of the stuck pixel. You may want to use a protective cloth so the object doesn't directly touch the screen. While poking, turn the monitor on and continue to poke for a few seconds. This may fix the pixel.
4. Tap on the stuck pixel with a soft but pointed object such as the edge of a pencil eraser. You will need to do this hard enough to create a discoloration at the point of impact but not so hard as to hurt the screen. After tapping the monitor five to 10 times, the pixel may start to behave normally.
