Laptop matrix verification program. Monitor test using PassMark MonitorTest. Reasons for dead pixels

A program for identifying “dead” pixels on rare crystal monitors. The negative brightness of PK displays may result in the detection of defective pixels. Such a pixel can produce different variations in red, green and blue colors, and can also lighten or darken. To identify such defects, use the Dead Pixel Tester program. Vaughn is idle time the most reliable way testing of monitors in “home” minds.
Dead Pixel Tester Fills the entire area of ​​the screen with the selected color color, and as a result of zipping, the pixel becomes clearly visible. Such a point does not present any negative effects on the monitor, but rather alleviates the additional weariness of the eyes of the student.

A short insight into the problem:

I would wonder, who has a problem? If the transistor does not work, the equipment can be repaired or exchanged under warranty. However, the technology for manufacturing flooring panels is complex, so large batches of panels can be produced without dead pixels awkward. And if the production had no more “clean” panels, the TV quality would be even higher.
Therefore, “bit pixels” are divided into three types, and all panels are divided into 4 classes (based on the ISO-13406 standard).
Type 1 - white pixel on a black background no.
Type 2 - black pixel on a white aphid.

Type 3 – colors (red, blue, green, yellow).
First class does not allow the appearance of “dead pixels”
Other class allows the detection of 2 defects of type 1 and 2, as well as 5 defects of type 3. This class is the most widespread in the TV market. Therefore, there are up to five defective pixels, in the opinion of the distributors NOT AND SLUMB.
Third class - there may be five broken pixels for type 1, 15 for type 2 and 50 defects for type 3.
Fourth grade - allows the detection of 50, 150 and 500 defects of 1, 2 and 3 types at a time.
It is often important or impossible to detect the presence of “broken pixels” while watching TV programs or DVDs. For example, a pixel that is stuck can only appear as a green dot on the black background and in the corner of the screen. You can watch the TV for a long time and not notice it, since the fragments are small, and the images change so quickly and the colors mentioned here do not appear often. In addition, “broken pixels” can appear for an hour as a result of a breakdown of the transistor, which indicates this point on the screen.

Programs for testing the monitor will now be used by PC owners. Perhaps, among all the information and diagnostic utilities, stench is the most popular. And all of this is because it’s too early for every consumer to get over buying a new monitor. It’s just that the vibration of the vibration generator is not enough for that model. According to the rules, the monitor must be strongly protested when purchasing, especially at low pixels.

Why are we testing the monitor:

Monitor testing programs will make it easier to check and adjust the EPT monitor. Special test images (templates) allow you to identify defects such as the absence of changes for different colors, insufficient focusing and voltage stabilization, geometry distortion, low contrast, unevenness of the light phosphor, broken pixels Having looked at a number of copies, we can select the one from which deterioration below the minimum norm.

RC monitors will require a different approach. All monitors based on the PK panel cannot have problems with geometry, alignment, stabilization, focus, etc. And the dispersion of parameters has disappeared without power, due to the blame of “broken” pixels, which are still growing, regardless of all the efforts of the processors. Prote, RK-monitors also test the trace. These are not just different copies, but models of different types. LCD monitors are clearly displayed in one view based on such parameters as: inertia (luminosity and blurring), color naturalness, color separation, brightness and contrast, evenness Identification. These parameters are either not specified in the characteristics, or are based on completely impossible methods.

When purchasing a TV or monitor, sellers promise to provide quick additional service - checking for pixel bits. Moreover, the service comes with a paid fee of 500 rubles or more. If you discover a defect in the booth, you will no longer be able to turn the TV back, to explain the stench. This is not a guaranteed drop, and the stench stinks of the radio. In fact, you can test such a matrix independently and without any hassle, without any complications. All you have to do is bring with you a special video and pictures on a flash drive for verification after reading our article beforehand.

Warranty issue

Why are a few broken pixels allowed? On the right is that the technology for generating the matrix of PK displays is very complex, and the device generator can’t afford its own generation. But such a defect can only be detected on an assembled device. Since screens are usually written off from gateways with minor defects, the price of TVs and monitors is increasing many times. So the following compromise was found:

• Virologists will deprive production at a great rate and will not raise prices.
• Buyers assume the presence of a small number of broken pixels, which is a guarantee. In this case, the buyer has the right to check the display before purchasing.

Acceptable thickness

How many dead pixels are acceptable? The advice on this food is to be located in international standard yakosti LCD TVs ISO 13406-2. There are 3 types of defective points:

1. Open or white – such pixels become open and steadily burn white.
2. Closed or black - such pixels are caught in the closed state and steadily burn black.
3. Colors - such pixels have the transistor that controls them out of tune, and they steadily burn in one of 3 colors: red, green or blue.

LCD devices are also divided into 4 classes. The first class is the highest, in the matrix of devices of this class the detection of defective points is not allowed. What is important is the large number of buildings above the market - a different class. The standard defines the permissible number of defective points different type It is necessary to comply with the maximum separation that is supported by it. Information for devices for the popular 2nd class is provided in the table below.

How to verify

To check the screen for defects, you need to sequentially apply pictures of the main colors to each one and carefully watch it, trying to identify points of another color. This is how bits of pixels look like. For example, if a white color is displayed on the screen, black and color dots will easily be visible. If the color is black, it is easy to see white speckles. Before the test, on the TV turned off, look at the particles of the saw and other mixture on the screen.

We have prepared a special archive for you where the video test will be held. It will consistently display images of different colors, which allows you to check for defects. Also the pictures themselves, so that you can take a closer look at the colors. You can take the test as soon as possible: . Unzip it and write it to a flash drive before going to the store. Before purchasing, ask the seller to play the video from the flash drive on your TV.

Update

There are a number of methods for updating broken pixels identified during testing. It is extremely rare and especially rare for corrected color points to produce results (type 3). Also, the test will show what helps the pixel get out of trouble again, even if the next day is unfavorable. Before that, you can easily connect the seaward points. That’s why we don’t really recommend doing any renovations, but let’s take a look at the methods:

• Software approach A matrix image is displayed on the screen, in which dots of different colors are seamlessly displayed. After 20 minutes, the problematic pixel may reappear;
• Mechanical approach: The TV is wet, through the server you press your finger on the dead pixel, the device is wet and the pressing stops. Using this method you can reset the matrix.

In such a manner We don’t want you to try to update pixels on your own. First of all, it won’t be practical, but in another way, you can earn a lot more money. It will be much better if you check the TV before purchasing, so that you don’t end up in the store, which is a warranty issue. And now you can earn money independently and cost-free, that’s all. Below you can watch the video test, which is in the archive, and also check your monitor on bits of pixels, flashing the video on the entire screen. Don't forget to select 720p(HD) in your program settings.
