This software tool allows users to easily check their PC, laptop, or tablet screen for dead pixels, scratches, or other defects. The portable version can be used to test screens before buying or during the warranty period, potentially allowing for a replacement. The program is small, free, and open source.

The program essentially fills the entire screen with a primary or custom color, allowing you to zero in on any pixels that do not match the selected color. This way, you can easily inspect the screen and detect any non-functioning pixels that may have gone unnoticed.
One of the best things about InjuredPixels is how easy it is to use. Simply cycle through colors using the arrow keys or by clicking the mouse, and access the main menu by right-clicking. Also, you don't need to install anything on your computer to use it, thanks to its portable version that can be downloaded and run directly.
Lastly, it's worth mentioning that InjuredPixels is a tiny, free, and open-source software that you can access on GitHub - giving you the chance to contribute, report suggestions, or issues. Overall, a highly recommended tool for anyone looking to put their device screens to the test.
