Pixel Healer (Windows)
Pixel Healer is an entirely free application from Aurelitec that fixes pixel problems. It’s compatible with many versions of Windows, from Windows 10 back to Windows 7.
Once downloaded, Pixel Healer will present you with a colored box window and a settings menu. Either click and drag or use the position and size options to place the color box over the area of dead or stuck pixel(s). Taking care not to look directly at the box (especially if you’re sensitive to flashing images), click the Start Flashing button.
The window will then flash multiple colors in quick succession. Leave it on for 30 minutes and then check the pixel again. Try this a few times to see if it works.
