To 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 .NET Framework application for Windows.

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, offering 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 and 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.

Most monitor manufacturers have a policy of replacing TFT monitors if they have a certain amount of dead pixels. The software Dead Pixel Tester is able to identify dead pixels by filling the monitor with straight colors. If a pixel is not able to display that color it will display a different one which means that you just discovered a dead pixel.

Using Dead Pixel Tester is not complicated at all. After downloading the application start it. Please note that it does not need to be installed which is always nice. A menu will appear that makes it possible to configure some settings but this is not necessary at all.

If you left-click your mouse on your screen you will notice that it will change color. A right-click will hide the menu so that you can inspect the full screen to see if there are any dead pixels on the screen.

If you spot none you can cycle through all colors to see if a dead or stuck pixel appears when the screen is shown in a different color. You could try to fix a dead or stuck pixel by launching the pixel exerciser and moving its window over the area of the dead pixel but the author himself is not so sure if this is working at all.

Ask the manufacturer of the monitor about their replacement policy to know if they replace the monitor if you found some dead or stuck pixels.
