LCD monitors may develop scratches or other defects that may end up in dead or locked pixels that are not easy to spot at first sight. InjuredPixels gives you the tools you need to detect pixels that don’t behave as they should in a simple and straightforward way. You can use it to check your monitors at home and to test second-hand and new monitors in a store before purchase using the program’s tiny portable version – its HTA text file can be run easily on any Windows platform (from XP onwards) without installation.

This open-source solution has no rival in the simplicity department. Software tools simply don’t come any simpler than InjuredPixels. In order to check if your LCD screen has any locked, hot, or dead pixels, you need two things – a flat well-contrasted color that covers all the pixels on your monitor and the possibility of switching between background colors in a quick manner. InjuredPixels offers you both. As soon as you launch the program, you will see your entire screen going all black, except for the program’s menu (which you can toggle on and off using the Escape key). Here you will see the various color options that come with the tool (high-contrast black, white, green, and blue), a custom color (yellow, by default) that you can change at any time, and a random custom color. All six active colors are numbered, so that you can change from color to color quickly just by entering their corresponding digits when looking for stuck pixels. You can also use the right and left arrows to move from color to color in a circular way.

Logically, the program needs to cover every single pixel on your screen to check that they’re all working properly, which will make your desktop disappear. You cannot run the program in window mode or minimize it to the status bar, so you will need to use the Windows key to find your way back to your other apps or quit the program using “Q”. There is not much more to it than this – InjuredPixels won’t fix your dead or stuck pixels, but will help you not to buy damaged monitors or to identify why certain areas of your screen are not displaying certain graphics or colors as they should.
