Welcome to DeadPixelTest.net, a free tool designed to help you identify and potentially repair dead or stuck pixels on your screen. This tool works by flashing different colors rapidly across your screen, which can sometimes help restore stuck pixels.

What is a Dead Pixel? A dead pixel refers to a pixel that no longer functions properly and stays either black or white. Stuck pixels, on the other hand, remain locked in one color, like red, green, or blue. Both issues can affect your viewing experience, but in some cases, stuck pixels can be repaired.

Uses: This tool can be used for:

• Detecting dead or stuck pixels on your screen.
• Attempting to repair stuck pixels by flashing colors rapidly.

Benefits: Using this tool might help:

• Fix stuck pixels without needing expensive hardware replacement.
• Improve the quality of your display for an optimal viewing experience.

Instructions: To use this tool, simply press the "Start Pixel Repair" button. Your screen will begin to flash multiple colors in full-screen mode, which can sometimes help release stuck pixels. The process will run for several minutes, and you can exit fullscreen or stop the process by pressing the Escape key or stopping manually.

Once the repair attempt is over, visually inspect the area where the pixel was stuck to check if it has returned to normal.
