Some people recommend a heat method where you use a hairdryer to warm the spot while youre putting pressure on the monitor to fix a stuck pixel. 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. Unfortunately, you can only use colors to analyze your screen, with no other methods, such as contrast bars. Interacting with the keyboard closes the application, and switching to a different color is done through the associated context menu. The test lets you change the color for better analysis, and it contains red, blue, and green. 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. On launch, an information panel shows up to let you know what and how needs to be done. This might require a bit of effort, and there are a few test cases to use in this regard. 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. Stability of the target PC is not affected, nor the integrity of the display. 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. Check pixels on a colored backgroundįirst of all, the application takes you through a setup process to make its functions available. 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. It gets pretty frustrating to have dead pixels in your display, but it can be difficult to tell. Long term use of the monitor, and even external circumstances can break it down, but not all at once, rather pixel by pixel. ![]()
