Alternatives to Fixing Dead Pixels

Pixel Healer (Windows)

PixelHealer is a completely free application from Aurelitec that fixes pixel issues. It is compatible with Windows 7, 8, 10, Vista or XP. After downloading, PixelHealer will present you with a colored box window and a settings menu. A word of caution though, users sensitive to flickering images should not look directly at the frame/application window, as the window will flash multiple colors in rapid succession while the application is running.

PixelHealer is more likely to deal with stuck pixels showing signs of life than dead pixels, which may remain unresponsive, but it has the potential to fix both, so try this dead pixel no matter how the injured pixel behaves repair.

Dead Pixel Test and Repair (Android)

With such a simple name, you’ll know that dead pixel testing and repair (DPTF) is a quick and easy dead pixel repair method for locating and possibly repairing dead or stuck pixels. It’s a free app with a self-explanatory and easy-to-navigate interface. Dead Pixel Test and Repair uses the same process as its rival apps, using a series of solid-color blanks on the screen to show broken pixels.

The developers recommend that you let the dead pixel test and fix run for at least 10 minutes to fix all the pixels, but we got better results when we let it run for a few hours so it had time to fix all the dead pixels. You need to have a fully charged battery or have the device connected to a power source while executing this tool.
