Every LCD monitor is composed of millions of tiny pixels made up of red, green, and blue sub pixels. Many times, all three sub pixels will be stuck on, and a pixel will appear as a white spot on your monitor (if it is a black spot, the pixel isn’t stuck, but dead, and can’t be repaired). The causes for this are many, but the majority of instances are due to either blunt force trauma or age. Not to worry, we can help with step by step instructions.
- Check and make sure that the LCD is clean. Using a scratch-free cloth and some compressed air, remove any excess dust or dirt.
- Make sure that monitor is displaying in its native resolution. You may have to check the manual for your monitor in order to determine what that resolution is. To change it, right click your desktop and go to properties. From the menu that pops up, go to the settings tab and adjust the slider to the desired resolution.
- Next, download and install UDPixel, a program that will help you identify and fix this pesky problem. UDPixel does require the .Net Framework, so you’ll have to download it as well.
- Once you have UDPixel up and running, increase the Run cycle option up to four seconds. Once done with that, click Run Cycle. Your display should then cycle through red, green, black, white, and yellow. Your stuck pixel should be viewable in every color except the one in which it is stuck. Click to stop the cycling colors.
- If you have multiple pixels, you may have to increase the flash window number by an increment of one for every pixel that is stuck.
- Next, click on start and position the five by five pixel box that appears around your stuck pixel and let it sit for fifteen or twenty minutes. When you’re done waiting, cluck on reset to turn it off and the repeat step 4 to see if the pixel is still stuck.
- If it is not working at this point, check and see if your monitor is under warranty. If so, you will have to replace the screen.
- If not, there are a couple more drastic steps that can be taken. Turn off your screen and apply direct pressure to the bad pixel with a stylus wrapped in a scratch-free cloth for five to ten seconds. Turn the screen back on and check the pixel.
- If this didn’t work, repeat the previous step a few times. You can even try gently tapping the affected area.
If you’re lucky, one of these options will repair the pixel and save you trouble and money of replacing your screen.

Great tip! After several moves, my monitor had developed a white spot and I couldn’t get rid of it. I tried this UDPixel thing and it worked great! No more annoying white spots! Thanks guys!
YES. FINALLY. Those little spots were so annoying!!!! I thought i was stuck with them.
