What is a monitor check for broken pixels?

In our time, technology is developing at lightning speed. It would Seem, yesterday, used cash registers, and today it is impossible to imagine a life without computers and gadgets. Every day there are all new models of mobile phones, scanners, laptops, tablets, and, of course, monitors for PCs. Previously, the computer screen was based on the technology of cathode ray tubes. Now is the time of LCD monitors.

A person strives to improve and succeed in the race for novelties in the world of technology. We spend a lot of money to modernize our electronic "friends." And you buy a cool monitor and start testing it. Watch movies, games are played, etc. As a result, notice the strange black or white dots on the screen, which prevent you from watching your favorite film. This defect in the computer world is called a "broken pixel". Let's figure out what kind of attack it is and how to fight it.

First of all, you need to clearly understand what a pixel is. Modern monitors reproduce the image thanks to high-tech matrices. The picture on the screen consists of a set of points, which are usually called pixels. In turn, this small particle matrix includes three subpixels: red, black and green. In so-called active matrixes, pixels are operated by thin-film transistors. In case this device fails, a black inactive point appears, which does not change its color when changing the image. This is the broken pixel. This kind of problem can be eliminated only in special laboratory conditions.

There is another kind of pixel malfunction - "stuck" points. In this case, there is a bright spot on an absolutely dark background. The main reason is the jamming of one of the three subpixels. This kind of defect can be restored at home. Black dots require intervention from experts.

There is a completely logical question: "how to check the monitor for broken pixels?" Of course, it is almost impossible to determine the defect by eye. Any seller will show you on the screen a bright multi-colored picture, and not test it on various backgrounds. This is how the monitor is checked for broken pixels. You should understand that this problem manifests itself on different backgrounds. That is, the red dot will be visible only on the green tone, etc. So when you purchase the goods, be persistent and vigilant. After all, modern computer screens are worth a lot of money.

Basically, checking the monitor for broken pixels is done with the help of special programs. It is very popular with Nokia Monitor Test utilities. The program is easy to use. Choose a color check mode and alternately test your screen using different backgrounds. If you are going to buy a new monitor, write the utility to disk and perform diagnostics in the store itself. Thus, you will have insurance in case of a malfunction. In fact, checking the monitor for broken pixels is an elementary procedure that will not take you much time.

There are a lot of programs that help diagnose. For example, a monitor test for broken pixels is carried out using a special program - Monitor Test 1.52. A fairly simple to use utility allows you to diagnose qualitatively any problems associated with the matrix.

Unfortunately, the broken pixels are in the matrices of laptops and tablets. This defect is typical for almost all budget versions of monitors. There are permissible norms, in which the maximum number of faults of this kind is specified. Almost in all stores, in addition to the basic warranty, the so-called Zero Bright Dot. With this innovation, the client has the right to make a return of the monitor if at least five non-adjacent bad pixels are detected. Before buying it is better to be safe. This will help you check the monitor for broken pixels. After all, no one will buy you a product with faults.
