InjuredPixels

Easily check your PC, laptop, tablet, smartphone, connected screen or TV for dead pixels, scratches or defects. Test any screen in the store, before buying, or during the warranty period, as you may get a replacement according to the manufacturer's dead pixel policy.

InjuredPixels fills the entire screen with a primary or custom color, helping you to easily spot pixels that do not match the selected color. You can easily cycle through colors, and clean or gently rub any area while testing. InjuredPixels is completely free, open source, doesn't show ads, and requires no Internet and no extra permissions whatsoever.
