Checking the monitor for dead pixels

A monitor is one of the most important parts of a computer, without which the operation of all other elements becomes useless. That is why it is so important that the screen shows a high-quality and clear image. You need to take care of this at the purchase stage. Recently, the so-called broken pixels have become the most frequent user problem. It is because of them that the use of the device becomes less comfortable, and in some advanced cases completely impossible. What is it? Is it possible to know in advance about the presence of damaged zones and what to do if they are still present? You will learn about all this in this article.

What is a pixel and what are broken pixels?

First of all, let's figure out what a pixel is in general. This is one, the smallest part of which the screen consists. Modern computer models have a huge number of pixels, which makes the picture more clear, understandable and with natural color reproduction. Having familiarized ourselves with the concept of a pixel, then we will analyze what a damaged zone is.

A broken pixel is a part of the screen that cannot correctly transmit color. There are several options for broken pixels, which are slightly different from each other:

  • some of them are in a constantly burning state;
  • others, on the contrary, remain black, that is, empty;
  • there are those that are capable of transmitting only one color and they cannot get out of this state;
  • the last variation is whole groups of dead pixels, which greatly complicate the use of the monitor.

Why you need a monitor for broken pixels when buying

It turns out that you can’t always be able to return a poor-quality monitor back to the store. Manufacturers very often indicate that the monitor is a product of the second grade, and not the first, and such a product, in accordance with the standard, may have a certain number of dead pixels.

It is unlikely that it will be possible to return, but nobody wants to use a damaged monitor. That is why it is necessary to conduct a test at the purchase stage. Do not be shy about having to ask the seller to check. You have every right to receive a quality product, because you give money for it, and in most cases are quite considerable.

IMPORTANT! Performing a test is a simple task. Therefore, you should not hope "at random" and think that the new computer certainly cannot have any problems. There is plenty of evidence that marriage in this area is extremely common. So be careful and buy only the monitor that will definitely not have problem areas.

How to check the monitor for dead pixels

There are several applications and sites with which you can easily check the screen for faulty zones. There is practically nothing to do on your own.

Each site or application offers several pictures or just solid colors, shades and gradients that are displayed on the screen and allow you to check its serviceability. Thus, you can evaluate the color rendition, broken pixels and many other malfunctions that you could only detect while using the computer.

The easiest way is to simply follow the link. For example, //monteon.ru. After starting, it remains only to run the test and move the colored bars in search of problems.

Sites differ from applications in that they almost always have some space under the menu, which cannot be verified. The application can be launched in full screen mode and view every millimeter of the screen.

What to do if problem areas still exist, but you have already purchased a monitor or simply do not want to refuse a very advantageous offer? You can try to fix the situation yourself, but there is still no absolute guarantee of the result.

Fix dead pixels

The first way is to install the special Bad Crystal program. It can be downloaded free of charge from the Internet. After starting, you need to move the window that appears to the place where the broken pixel was formed and leave for a while. The principle of the utility is to change the color in the right place, which causes the pixel to finally get out of the usual state. In most cases, the problem is resolved in about half an hour, but sometimes you have to leave the computer turned on for several hours.

IMPORTANT! Please note that it is not always possible to correct the situation. Some pixels do not start working correctly, and if the screen was damaged mechanically, then using the program will be completely useless.

Another, less common option to find a malfunctioning point on the screen is to periodically press on a damaged area with a soft object. For example, a cotton swab. Actions must be repeated for several minutes, not more than fifteen. The pressure should be very carefully, because you risk damaging other parts of the screen. This method also does not always work.

Now you know why it is so important to make timely diagnostics of the monitor and what you can try to do if dead pixels still appear on the screen.
