Monitor test for broken pixels. Several ways to check

When buying new equipment in stores, you should always check it for malfunctions. As practice shows, some of the new components may have obvious defects. To protect yourself from problems, you need to do a test of the monitor screen. We will talk about this in the article and learn several ways of testing.

Verification Assistants

There are programs that greatly facilitate the task of testing and tuning monitors. They use special images that make it possible to identify the following malfunctions:

  • Inadequate color rendering.
  • Poor mixing of rays of light.
  • Incorrect image stabilization.
  • Geometric distortion.
  • Low indicator of brightness and contrast.
  • Uneven color rendering.
  • Dead pixels (most common)

When testing the monitor with programs, you can detect violations in advance and refuse to purchase. If you have already purchased a screen, you can easily prove the presence of defects, and then return the goods to the store.

Features of LCD monitors

To themselves, they require a more reverent approach. For structural and technical reasons, LCD monitors cannot have most of the problems described above. Manufacturers are struggling to minimize the number of defective LCD panels. However, problems with the monitor pixel test remain.

Testing is not carried out on individual copies, but on specific models of any manufacturers. And all due to the fact that they are very different from each other in such parameters as:

  • Viewing angle.
  • "Lubrication" of the picture.
  • Screen resolution.
  • Main parameters.
  • Brightness and contrast.
  • Color accuracy
  • Internal backlight.

These parameters are not indicated in the technical specifications. And to find at least some data on it is extremely difficult. You can search on specialized sites or ask a consultant in the store. So, let's figure out how to do a monitor test for broken pixels.

Method One: Through the Monteon Online Service

This is the most convenient way, because you do not need to download anything to your computer. And at the same time, memory is not cluttered, and the chance to "pick up" virus software is minimal.

The Monteon service allows you to evaluate the capabilities of the screen and conduct a monitor test. For this, special templates are used on the site to help you see monitor defects. You can not only check, but also configure your screen settings. The test, which is provided by the Monteon website, is very convenient and does not require unnecessary actions.

To test your monitor, you must follow the following algorithm:

  1. Go to the site. To do this, in the search, type the phrase "monitor testing." And the Monteon site will be the first in the list.
  2. In a new browser window you will see the start page, click on "Start".
Service "Monteon"

As soon as you start the test, you will see a static picture. It allows you to evaluate the quality of the screen and color reproduction, and it is also easy to notice the "broken pixel" here. This image can be found freely available on the Internet, but there are other images on this site.

Start testing

If you release the mouse and do not touch the keys, the bottom panel will disappear. There will be only one image that can be changed. To do this, click on the arrow or click on the mouse.

Additional site features

If you look closely, at the bottom of the screen you can see the inscription "Gradients". By clicking on this item, you will call up the menu. In it you can choose to test the following parameters:

  • Color rendering. In this option, you are given the opportunity to look at how sensitive your screen is to colors and how it displays them.
  • Gradient Demonstrates a smooth transition from one color to another.
  • Flicker. When you select this item, you will see a picture with many dots. They will show whether your screen will flicker or not.
  • Sharpness. Demonstrates picture fidelity.
  • Contrast and brightness. If you decide to see the maximum values ​​of these parameters, then feel free to choose this item.
  • Geometry and meshes. A picture is shown which is divided into its component parts.
  • Dynamic tests. Indicate the reaction speed of the monitor.

To end the keyboard test, press Esc. Or click on the icon of the house, which is located on the left side. Monitor tests will help you choose a quality product. But not only on the Monteon website you can test your screen. For this, other special programs were developed. About which we will talk below.

Method Two: IsMyLcdOk Program

It works primarily with LCD screens. The program is free, and you can download it from the official site. Or choose any other resource that allows you to download it.

Russian localization is available, which greatly simplifies the work with the utility for checking "broken" pixels. The program does not require installation and weighs only 38 Kb.

If you click on a specific number, the application opens a new window with an image for you. The interface is quite minimalistic and simple. One minus - you can’t remember all the numbers, so you have to click at random.

Program to check

Third way: Nokia Monitor Test

It is distributed free of charge and has Russian localization. For some reason, it does not support new versions of operating systems. And the program only works with the old ones: Windows XP and Windows Vista.

But this does not prevent her from being one of the best utilities for testing screens. She can also change the monitor settings so that the image is transmitted in a better view.
