Have you just bought a monitor or LED screen, and you are afraid that it does not work correctly or has minor problems, such as dead pixels that cannot be detected with the naked eye? You should know then that some applications have been specially developed with this type of interest, such as UDPixel, to which we will refer in this article to tell you a little about how it works.

The first thing you have to keep in mind about UDPixel is that it is a platform responsible for detecting dead pixels, i.e., the pixels of our monitor that remain black, without changing according to the circumstances of the case. And how can it detect the presence of these dead pixels? Speedily and easily, paint the screen in different colors to see its reaction.

In this way, UDPixel will let you know in a few seconds if you have dead pixels on your computer, and as you can see in the screenshots we have made when changing color, they should be exposed immediately. Of course, luckily, we don't have any dead pixels on the computer used for the test, but you can be sure that if you, unfortunately, have any, you will discover it immediately.

This tool, which for some time was known as UndeadPixel, thus subjects all the pixels of our monitor to a quick analysis to detect what is the possibility of any of them recovering.

UDPixel has a built-in system, thanks to which it takes advantage of a small square of the screen, or the whole of it if that is what you intend, to change color constantly, and thus check for the existence of dead pixels. You have to consider that you can customize many aspects of this application, for example, to determine the update frequency of the colors, the number of squares, or how much they cover.

In any case, you should consider in the same way that you can also produce the tests manually, selecting only one of the many colors offered by UDPixel, to see how the monitor reacts to each of them. To be sure that a pixel on your monitor is dead, you have to see how it stays black as you make the color changes, which in these cases is unusual but possible.

If you let the automatic test we mentioned at the beginning occur, you have to know that there are two possibilities, one negative and one positive. The first one is that after the test, the pixel that we have detected as dead has come back to life; the second one is that, unfortunately, it remains dead, and the case is that if there are many dead pixels, you should start thinking about the possibility of acquiring a new monitor.

But, before launching it on your computer, you must take into account that it is necessary to install Microsoft .NET Framework because otherwise, you will not be able to run it, so you have to take the trouble to download this system beforehand. Anyway, don't worry because Microsoft .NET Framework downloads in seconds and doesn't take up any space on your PC, and it's even very likely that you had it installed before as well.

The UDPixel interface complies without problems. Here we have to consider that it is functional even when only available in English, which will be a huge advantage for many users. On the other hand, we cannot lose sight of the fact that it is primarily a program that works in the background, which is why it is not important what it looks like.

If we had to talk about the main strong points of UDPixel, we would have to point out that it allows us to detect the presence of dead pixels on our monitor. Still, it has a series of quick and automatic tests, thanks to which we can recover them so that they continue working. In this way, a single platform performs tasks that are usually only carried out by two different ones.

And if you are wondering if UDPixel has weaknesses, you should know that it does. In particular, we will focus on just one of them, which, although it is a bit unavoidable, we would like its developers to improve at some point. We are talking about the fact that attempts to recover dead pixels consume a lot of time, and sometimes we have to leave it for hours working to find out if they have a solution.

In conclusion, we can say that UDPixel is a good tool that you should install and try on your computer to check if you have dead pixels on your monitor, mainly if you have not performed these analyses for a long time. It is a utility that consumes almost no system resources, so you can run it in seconds on both old and modern PCs without significant inconveniences.
