The monitor is one of the most important components of a computer, because it is he who is responsible for the beauty of the picture. No matter how wonderful and powerful the video card on your computer is, you cannot do without a good monitor that can present graphics in all its glory. But, besides how good the monitor is in its characteristics, it’s also important how efficient it is, because any equipment can be defective or fail for a variety of reasons. In this article we will look at how to check the monitor for operability, dead pixels and other possible problems. Let's get started. Go!

Monitor - one of the most important components of a computer

If you are buying a new or already used monitor, be sure to check it carefully. The tips below will help you identify any possible problems and malfunctions.

Start by inspecting the cables. Banal cable damage is one of the most common problems. If everything is in order, connect the monitor to the computer and turn it on. Keep in mind that even if the screen is new, it may have broken pixels. You can find them by eye, but this is not the best approach, because on modern screens with high resolutions and high pixel density, this will be very problematic. Fortunately, there are special programs that allow you to quickly and effectively detect a defect. One of the most popular software products of this kind is the Tireal TFT Test utility. Working with this program is very simple. Run each of the available tests in turn. There are four of them. You should start with a test of primary colors, which will allow you to identify which pixels do not display from the main color range (red, black, blue, green, pink, white). As a rule, this test is sufficient, but it will not be superfluous to run the rest, so that the test is as efficient and complete as possible.

Tireal TFT Test Program

Tireal TFT Test allows you to check the screen for the absence or presence of noise, how well the gray color and all its shades are displayed. If you are going to work on a computer with graphics, be sure to run the RGB test. This software product allows you to fully test the monitor for performance, so it is recommended to maximize the use of Tireal TFT Test functionality.

Unfortunately, it is unlikely to be able to conduct a full test directly in the store. As already described above, the detection of dead pixels requires special software that no one in the store is likely to provide to you, so checking this aspect should be done at home. But even in the store can be quite extensive testing.

Start with a blink. Go to the screen settings and set lower values ​​for brightness and contrast. So flicker will be much easier to detect. Then turn on some video and see if any artifacts appear. Under the artifacts are meant plumes arising from the movement of objects on the screen. Next, see how the picture is displayed under different viewing angles. Shine something on the screen to see if the highlights will appear. Do not neglect the sounds that the monitor emits in the process. Any strange or too loud noises indicate that this product is poorly assembled or something in it does not work as it should.

Now you know how to monitor the monitor for operation with and without a computer right in the store. Check out in the comments if this article was useful for you, share your advice on this issue with other users and ask if something has remained incomprehensible.
