LCDTester

While widely adopted, LCD screens are prone to dead or stuck pixels and some other flaws you definitely want to be aware of so that you can either resort to your warranty or try your hand at some workarounds.

But in order to identify the problem, an application such as LCDTester could come in handy since it proposes a very simple means of checking your screen for this kind of issues.

The application’s user interface entails one single button that lets you fully enjoy the program’s functionality, which means that, in order to carry out a test, you simply need to click on “Begin.” At this point, the program initiates a sequence of colored screens. More specifically, the software utility turns your entire screen white, black, red, green, then blue so that you can see whether problematic pixels or subpixels affect your user experience.

You have full control over the duration of the experiment since you need to click each time you want to change the color of your screen, with the cycle being maintained until you press any key on your keyboard.

In case there are any defective pixels, you should see an improperly colored area due to the fact that said pixels are unable to work in accordance with the rest of them.

Unfortunately, the application cannot actually fix the problem, especially considering that it might be caused by manufacturing processes. But in case you are dealing with stuck pixels, your troubles could be temporary, and simply flashing various colors on your monitor could be one of the ways to address the issue.

All things considered, LCDTester is a user-friendly tool that helps you spot dead and stuck pixels in the blink of an eye so that you can subsequently take measures against the problems.
