Another very significant feature of PassMark MonitorTest is the ability to diagnose the condition touch screens. However, unlike competitors, this program is paid.
Dead Pixel Tester
This program is designed to detect so-called dead pixels. To search for such defects, tests similar to those present in other representatives of this category of software are used.
The results of the equipment research can be sent to the website of the program developers, which, in theory, can help monitor manufacturers.
If you have any suspicions regarding the correct operation of the monitor, it would be wise to use one of the software products described above. All of them can provide a decent level of testing of the main parameters and will help to detect any defects in a timely manner, while they can still be corrected.
A program for identifying “dead” pixels on LCD monitors. A negative quality of LCD displays is the possible presence of defective pixels. Such a pixel may have various errors in the display of red, green and blue colors, and may also be illuminated or darkened. The Dead Pixel Tester program is used to identify these types of defects. It is a simple and reliable way to test monitors at home.
Dead Pixel Tester fills the entire screen area with a user-selected color, making the damaged pixel clearly visible. This kind of point does not pose any negative effects on the monitor, but contributes to additional fatigue of the user's eyes.

A short excursion into the problem:
It would seem, what is the problem? If the transistor does not work, then the equipment can be repaired or exchanged under warranty. However, the panel production technology is so complex that it is impossible to produce large batches of panels without dead pixels. And if only “clean” panels were put into production, the cost of TVs would be very high.
Therefore, “dead pixels” are divided into three types, and all panels are divided into 4 classes (specified in the ISO-13406 standard).
Type 1 - white pixel on black background
Not.
Type 2 - black pixel on a white background.
Type 3 - colored (red, blue, green, yellow).
First grade
prevents the appearance of “dead pixels”
Second class
allows the presence of 2 defects of types 1 and 2, as well as 5 defects of type 3. This class is the most common in the TV market. Therefore, the presence of up to five defective pixels, according to manufacturers, IS NOT A DAMAGE.
Third class
- may have five dead pixels of type 1, 15 of type 2 and 50 defects of type 3.
Fourth grade
- allows for the presence of 50, 150 and 500 defects of types 1, 2 and 3, respectively.
Determine the presence of “dead pixels” by eye when watching TV programs or DVD discs it is often difficult or even impossible. For example, a stuck pixel may only appear as a green dot on a red background and in the corner of the screen. You can watch TV for a long time and not notice it, because the dot is small, and the image changes quite quickly and the combination of these particular colors in this place is not often found. In addition, “dead pixels” can appear over time as a result of breakdown of the transistor responsible for this point on the screen.

Monitor testing programs invariably attract the attention of PC users. Perhaps among all information and diagnostic utilities they are the most popular. And all because every user will sooner or later worry about buying a new monitor. Simply choosing a manufacturer and model is not enough. According to the rules, when purchasing a monitor, it is necessary to meticulously test it, especially for dead pixels.
Why we test the monitor:
Monitor testing programs make the task of testing and adjusting a CRT monitor easier. Special test images (templates) make it possible to identify defects such as lack of convergence of rays for different colors, insufficient focusing and voltage stabilization, geometry distortions, low contrast, uneven glow of the phosphor, broken pixels. Having looked at several copies, we can select the one with deviations from standards are minimal.
LCD monitors require a different approach. All LCD panel based monitors cannot have problems with geometry, convergence, stabilization, focus, etc. And the spread of parameters is generally not typical for them, with the exception of “broken” pixels, which are still encountered, despite all the efforts of manufacturers. However, LCD monitors should also be tested. Just not different specimens, but models various manufacturers. LCD monitors differ significantly from each other in such parameters as viewing angles, inertia (afterglow and smearing), natural color rendering, color resolution, brightness and contrast, backlight uniformity. These parameters are either not indicated at all in the characteristics, or are measured using completely inadequate methods.

IN modern world The lion's share of professions involves working on a computer. At the same time, regardless of whether the time spent in front of the monitor screen lasts for a couple of hours or far exceeds two-thirds of the day, it is important to take care of eye health by correctly adjusting the brightness and color rendition of the display. The same applies to spending time for entertainment. In professional activities related to the processing of digital images, the quality of display of colors, shades, and contrast plays a significant role, and the factory parameters do not always correspond personal requirements user.
TOP programs for checking and adjusting the monitor.
Here everything depends not only on the resources of the device and the use of its full potential, but also on individual perception, which varies, including changes in external factors, such as the lighting of the room where work is being done and the distribution environment luminous flux. Taking into account working conditions, as well as personal visual preferences, sensitivity to light, the monitor is adjusted.
You can make spending time at the computer more comfortable by regular means operating system, setting parameters is available from the Control Panel. Moreover, if the goal is to bring conditions closer to ideal, maximally adjusting them to your own requirements, it is better to use special software that offers a wider range of capabilities than standard tools. When diagnosing screens, programs help identify inconsistencies and adjust parameters to optimal values. Software that allows you to adjust the operation of the display has various functionality and can be useful to every user, regardless of the purpose for which the computer is used.
The task of setting up the display occurs both immediately after purchasing the device and after a certain period of use, since over time the matrix wears out and no longer displays colors as before. Sometimes the monitor comes with its own software with reference samples, designed for specific model, but there are also universal remedies. You can test the display and adjust its parameters based on the test results using special online services or software that requires installation. Software tools can be used to check the monitor for dead pixels, and also include their treatment if detected. Diagnostics performed in a timely manner will allow you to avoid unpleasant moments associated with incorrect work or complete failure of the device.

Since the human eye will not be able to accurately determine how incorrect the display image is due to the natural features of the structure and ability to adapt, it is advisable both when purchasing a new monitor and for the purpose of preventing the old one to use a special software, allowing you to identify defects in a timely manner and avoid unexpected expenses. Choosing the right software is a purely personal matter; it all depends on the requirements for the program, the need to perform certain tasks and the convenience of the user.
How to check for stuck pixels?
Let's launch the program. We will be presented with several objects for testing: PC monitor, mobile device, LCD device for TV. Select the one you need (in this case, a PC monitor) and click “Monitor defective pixels.”
A program window will appear. Select the first flicker speed.
By expanding the program window, you can see blind points that do not change. This is a stuck pixel.
In order to restore a dead pixel, you need to register the program, which costs real money. According to user reviews, Bad Crystal 2.5 FINAL restores stuck pixels only on those monitors whose operating life does not exceed 3-4 years.
