16 Best Free Dead Pixel Test Software For Windows

Here is a list of Best Free Dead Pixel Test Software For Windows. These dead pixel test software help you detect a dead pixel on your LCD/LED screens. Moreover, some dead pixel test software also claim to fix/repair the stuck pixels.

All of these software work on the same principle of flashing colors. You can change the colors either manually or automatically after some defined period. During a dead pixel test, you should look at the screen carefully. Hence, it is advised to clean the screen with a soft cloth so that the dust particles will not disturb the LCD test.

While some of these dead pixel test software offer a custom color feature, some do not. The custom color feature lets you perform a dead pixel test on your own choice of color. Besides this, some dead pixel finder come with different patterns to detect a dead pixel.

These software might also work on some CRT and TFT display screens, but I am not definitely sure. I tested all of these software on different displays including LCD, LED, and even on CRT, but all the displays were healthy. Hence, no dead pixel was detected.

Monitor Test

RGB Boxes divides the whole screen into four parts; each having a different color (red, green, blue, and white). You can maximize the white color to full screen in the Pure White method, but I did not find any option to maximize any of the primary colors to full screen. Due to unavailability of this feature, there may be a great chance to miss a dead pixel on the screen. The Grid Lines method generates a grid pattern on the entire screen, whereas Text mode fills the complete screen with some text.
