InjuredPixels can be used to test a new LCD monitor before purchasing, or an already purchased monitor during the warranty period (as you may get a replacement according to the manufacturer's dead pixel policy).
InjuredPixels can be run directly without having to install it on your computer: just download and run.
A defective (hot, dead or stuck) pixel is a pixel that does not illuminate properly or does not display the correct color output. It usually looks like an annoying black, white or colored spot on your screen. (For more information read this Wikipedia article)
InjuredPixels fills the entire screen with a primary or custom color, allowing you to inspect the screen for pixels that do not match the selected color. The program is easy to use: click or use the arrow keys to cycle through colors or right-click to get the menu with the main commands.
