InjuredPixels is a free portable program for devices running Microsoft's Windows operating system to test for stuck or dead pixels.
A defective pixel on a computer monitor can be really irritating to the user, depending on its position on the screen. These pixels are known as stuck, dead or hot pixel, and the terminology determines whether the issue can be fixed or not.
They have in common that they do not display the color output correctly, which means that they display one color all the time. This color most often is white or black, but it is also possible that the pixel shines in another color instead.
Too many dead pixels on a screen usually mean that it is possible to get a replacement from the manufacturer. A dead pixel test can be used to find out if a monitor has dead or stuck pixels.
These tests change the computer screen to a solid color, so that dead pixels can be spotted easily. Injured Pixels is one of those applications.
The dead pixel tester is available as a HTML Application (HTA) for Microsoft's Internet Explorer, and a standalone portable application for Windows.
Update: Recent versions are also available for Android. They do support multi-monitor setups as well, and there is a commercial version available as well which you can test and buy on the developer's site.
The program is real easy to use. It opens up in full screen and changes the whole screen to black. The color selection menu is available then right away. It offers you options to switch to predefined colors and custom colors. This can be done with the mouse, or by using the left and right arrow keys on the computer keyboard.
Filling the screen with one solid color reveals dead, stuck or hot pixels on the screen. Injured Pixels does not offer options to unstuck pixels, for that look at Fix dead or stuck pixels.
The biggest advantage of the dead pixel tester is that it is easy to use, and that it can be used to fill the screen with custom colors. It can be downloaded directly from the developer website over at Hello Programming. Injured Pixels requires either Microsoft's Internet Explorer (if the HTA application is used) or a 32-bit or 64-bit edition of the Windows operating system and the .NET Framework 2.0.
