Dead Pixel Checker

Long term use of the monitor, and even external circumstances can break it down, but not all at once, rather pixel by pixel. It gets pretty frustrating to have dead pixels in your display, but it can be difficult to tell. In this regard, Dead Pixel Checker can help you run a simple test to find dead pixels to see whether or not you might need to buy a new monitor.

Check pixels on a colored background

First of all, the application takes you through a setup process to make its functions available. However, it doesn’t make any changes to system registry entries, so you can just as well have it deployed on a thumb drive in case you want or might need to verify monitors of other computers. Stability of the target PC is not affected, nor the integrity of the display.
The test consists of manually detecting dead pixels, since there’s no actual way for a computer program to tell whether or not there are any. This might require a bit of effort, and there are a few test cases to use in this regard. On launch, an information panel shows up to let you know what and how needs to be done.

Several colors to choose from

The application covers the entire screen with an opaque color so that you can easily eliminate even the slightest doubt regarding dead pixels, or actually confirm them. The test lets you change the color for better analysis, and it contains red, blue, and green.
Interacting with the keyboard closes the application, and switching to a different color is done through the associated context menu. Unfortunately, you can only use colors to analyze your screen, with no other methods, such as contrast bars.

In conclusion

Taking everything into consideration, we can state that Dead Pixel Checker is a lightweight application you can use to check whether or not that spot on your screen is a piece of dust, or a dead pixel. Although it doesn’t contain many test cases, the variety of colors can be enough to detect dead pixels in most circumstances.
