Test for presence of dead pixels torrent. Self-conversion of LCD TV on bit pixels. What is a TV pixel

Good day.

The monitor is an important part of a computer, that kind of picture quality on a new one - to lie not only the efficiency of a robot, but ale th zir. One of ourselves partial problems with monitors - visibility dead pixels.

Dead pixel - the same dot on the screen, how to change your color when changing the picture. So it’s like burning white (black, red thinly) in color, not conveying color, so burn. There are so many such points and stench in the visible places that it is impossible to work!

Є one nuance: click when buying a new monitor, you can get a monitor with broken pixels. Nayprikrіshe, that a bit of dead pixels are allowed by the ISO standard and it is problematic to turn such a monitor at the store.

In this article, I want to tell you about the number of programs that allow you to protest the monitor against the presence of dead pixels (that will prevent you from buying a non-acidic monitor).

I sMyLcdOK (the best utility to search for dead pixels)

Rice. 1. Screenshot of IsMyLcdOK for the hour of testing.

At my humble glance - tse one s short utilities for the joke of broken pixels. After launching the utility, it will flood the screen with different colors (the world has numbers pressed on the keyboard by you). You need more respectfully stare at the screen. As a rule, if there are bits of pixels on the monitor, you should mark them once after 2-3 “fills”. I strongly recommend to vikoristannya!

Advantages:

To run the test: enough to run the program and press on the following numbers on the keyboard: 1, 2, 3 ... 9 (and that's it!);
Available for all versions of Windows (XP, Vista, 7, 8, 10);
The program is only 30 KB and does not require installation, but it means that it can be installed on a USB flash drive and run on any computer with Windows;
Irrespective of those who need 3-4 fillings for re-verification, the programs have more.

Dead Pixel Tester (At the translation: a tester of dead pixels)

One more arcane utility, as it is easy to know dead pixels. The program itself does not require installation, just download and run it. Support all popular Windows versions(Including ten).

To start the test - just run and change color modes, change pictures, select fill options (in a flash, everything works in a small window, how you manage it, you can close it, how to get excited). Auto mode is more appropriate (just press the “A” key) - and the program will change the colors on the screen independently with a small interval. In this rank, literally for the khvilina, you are appointed: chi varto to bathe the monitor.

Monitor test (online review monitor)

Crimean programs, which have already become the standard for monitor rechecking, use and online services for searching and displaying dead pixels. Pratsyuyut stench for a similar principle, the only difference is that you (for reverification) will need the Internet to go to the whole site.

What to say, don’t start talking about it - because the Internet is not at all stores, where you can sell equipment (plug in a USB flash drive and run the program from it, but I look, it’s better and better).

As for the test itself, everything is standard here: we change the colors and marvel at the screen. Variants of re-verification to finish richly, then with a respectful approach - a pixel is not worth it!

Before speech, on this site there is a program for zavantazhennya and run without intermediary in Windows.

If after the purchase you saw a biting pixel on the monitor (and even worse, if it’s in the most prominent place), then turn it to the store, on the right side of the cuff. The bottom line is that if you have a smaller number of dead pixels (call 3-5, lie down like a picker) - then you can change the monitor (with such vipadkiv).

Shopping away 🙂

Zamovivshi tv_zor online і v_dpravilsya in the store for otrimannyam goods, spozhivach often forgets about revіrku tvіzor on nayavnіst beatih pіkselіv, vnaslіdok izikuє come home rozcharuvatisya in schoyno kuplenoї rechі.

The lack of defects in the rare-crystal matrix guarantees only the best models of displays, the parsley coristuvachev should be respectful and check the screen before buying it independently.

Pixels are units of the matrix of the RK-screen, the stars are created like an image. The head power of the pixel is influencing its color change: electricity, the amount of which is regulated by a transistor attached to the TV, suffocating the microelements and rare crystals to change their coloration.

Завдяки перестановці червоного, зеленого та синього субпікселів та інтенсивності підсвічування у певній точці монітора формується той чи інший колір – якщо ТВ-апарат має 4К-роздільна здатність та відображає контент зі швидкістю 30 FPS, в секунду може відбуватися понад 250 мільйонів подібних «рокувань».

Bit pixels on TVs are the most important elements of the display, which do not change the color for any minds.

Although this defect is practically not visible to the human eye during dynamic cinematic scenes, it can be uncomfortable when looking at static images: “beat” dots are clearly visible on the aphids and make you concentrate on the pictures that are being shown.

Number of dead pixels allowed

Leather maker of televisions declaring admissible price instead of in the matrix of broken pixels - products, in the course of the pre-sale re-verification, if a number of defects were revealed, which exceeded the installation limit, it is guilty to be defective.

Such top companies, like Samsung and LG, allow no more than two dead pixels and no more than 5 incorrectly functioning subpixels per one million dots: for example, already 4K-permission is calculated as 8 million in single matrixes, 64,0 incl. up to 16 defective pixels and up to 40 “stuck” subpixels.

Oskіlki pikseli, scho properly pratsyyut at factory tests, can get out of tune already before the hour of operation of the TV set, the goiter tester can give a guarantee of full pratsezdatnosti matrix stretch regulated by international or domestic help terms.

For the presence of “lighted” pixels on the TV display, the coristuvach may have the right to a cost-free repair or I will replace the extension.

Tsіkavo, scho standard ISO 13406-2 obmezhuє vіdpovіdіnіnіnіstі kompaniї one fate, and program Zero Bright Dot vіd LG - trioma.

Reasons for appearing

The reason for the appearance of broken dots on the matrix of a color TV can be:

overheating or overcooling I will add. In the wake of high or low temperatures, the sub-pixels harden and lose their edifice in the middle of rare crystals;
water content dovkilla. Increased moisture content, which is not safe for the RC-lining: when moisture hits the matrix, the illumination of the area or the white dots of the display is established;
voltage strips. Zbіy y electric lines you can bring the transistor out of the fret, as a result of which the energy that goes to the RGB matrix, zmuschi subpixels take a fixed position;
Destruction of the technology of virobnitstva. Let's just say that in most cases, factory slabs are equipped with only three of the most important factors - for the first time in the matrix production, go through multiple procedures of washing, drying and lithography, least of all undertreatment technological processes which lead to defectiveness of the final product;
Monitor alternative for displaying static content. With a trivial display of one and the same picture, the transistor may burn out, and the crystals - "caught". In case of problems, it is not insured to install TV sets with support for HDR technology (10-bit and Dolby Vision).

Also, the matrix can suffer for an hour of slow transportation of the TV set to the point of sale: no matter how hard it is to fix it at the warehouse, the crystals are more sensitive to sharp mechanical shipments.

How to convert the TV on bit pixels

In order to learn about the elements of the TV matrix, it is recommended to select a special gallery of monochromatic images - the same with Smart-TV programs for display verification is not necessary.

Algorithm for testing the view screen on the application by looking for more points:

Capturing a special collection of images on a flash drive.
Connecting a memory disk to a TV set via a USB interface.
View on the television of a monochromatic picture to this particular type- Chornii).
View of the display: the white bits of the elements are guilty but are clearly marked on the dark aphids.

For the search for black dead pixels, it is necessary to highlight the lightness of the image, and for the manifestation of RGB defects - some kind of background that contrasts with the bug.

It’s a pity, the coristuvachevs need to rely less on the severity of the damp dawn, it’s impossible to automate the process.

Starry look at the purchase

Deyakі resellers to give paid service re-verification of a rare-crystal display for the presence of broken pixels: the clerk selects a TV set, and the sales assistant tests the display for additional interest in image attachments.

Let's just say that payment for such a service is less than necessary for the need to recheck a 4K monitor, defective pixels, which may not be remembered on aphids of millions of practical units.

Warranty drop

The service center does not have the right to responsibly exchange a defective TV for a new one if the vibrator violates the ISO 13406-2 regulation.

The standard determines the permissible number of bit elements of the display matrix for that class of add-on:

You can recognize the class of the display from the technical documentation that is added to the TV. Further, it will be told that you should work with the removal of the guardianship service center.

The jubilation of beaten pixels on TV

The exuberance of a color TV (for example, Samsung's variations) looks like this in the minds of home minds:

launch of a special video. It is necessary to add a video clip to a flash drive, which “warms up” the matrix, and turn on this video on TV for 40-50 minutes;
"Massage" of inappropriate individuals. It is necessary to press on the bits of pixels behind the help of a magnificent cotton swab - here it is important to understand that for the supra-worldly pressure on the matrix, the final result can be seen by the proliferant bazhany.

Let's just say that bit pixels are so used to being digital technology.

Podbag

Now you know that such bits of pixels are the same as the most distorted their presence in the matrix of the new TV.

It is important that the savior may have the right to a cost-free service only after the recognition of the inconsistency I will add to the declared ISO 13406-2.

Іz tsim tsіkavim zavdannyam stakaetsya skin buyers when choosing a new TV. It's no secret that in the store when buying a daily TV, managers proponuyut paid service - turn the screen of the TV on the beat of the pixels and the clarity of the sound. Naytsіkavіshe pіd pod rozmovi posilayutsya on servіsnі tsentrі in yakshcho You'll show one or a bit of beaten pіkselіv, all the same you'll see visnovok, scho TV is right and there's no reason to turn the defective one. Even after the ISO 13406-2 standard, a new TV set from a number of bit pixels up to 7 pieces will allow you to turn quickly without pretensions to the store. Reports about this ISO 13406-2 can be found on the Internet.

So we know that under the law the rights of a savior for the last 14 days, the store that sold the TV set is "necessarily guilty of replacing" the TV set for a different one, or turn a penny. Tse commandment word nibi calm. Ale, not everything is so good, as it turns out. Shop to save you a TV replacement or a return of a penny koshtіv, only if you bring an official visnovok from the warranty service center about the inapplicability of the name to the TV.

To indulge yourself in wasting time and money, I recommend reviewing the TV set before buying a flash drive for help.

Converting a new TV set on bit pixels from a flash drive

When you buy a modern TV set with a USB socket, it's easy to do a bit pixel conversion.

The archives below contain 9 photographs of a different building (1920x1080 pix) and a movie trailer format 1920x1080 mkv HD. You need to transfer it to a USB flash drive.

Install the flash drive in the roses of the new TV.

For the help of the remote control, turning on the TV in the menu - connect USB flash drive. Let's choose to review the photos by choosing our test photos in the menu.

According to the blackness, we look at 9 colors of photographs and at the broken pixel, or how many bits of pixels we see on the TV screen.

Files for TV conversion to bit pixels

WinRar zipped files. Hurry up and ask for the help of an archiver.

Whether or not problems in robotic technology are already unacceptable and often lead to serious consequences to a new waste of practicality. For the timely manifestation of problems, that advancement of possible folds in the future may be sensible to specialize software security. The largest annual representatives of this category are presented in this material.

A cost-free software product of commercial retailers, which has all the necessary tests, allows you to carry out a complete diagnosis of all the most important parameters of the monitor. Among such varieties of colors, different equals of brightness and contrasting images.

Of course, at the main window of the program, you can take away the essential information about all the outbuildings, which can be seen as a graphic image.

PassMark MonitorTest

This representative of the described category of software is reviewed in advance, because there are complex tests here, which ensure security and the most complete re-verification of the monitor's performance.

Also, the essence of PassMark MonitorTest is the ability to diagnose touch screens. However, in view of competitors, given programє paid.

Dead Pixel Tester

Tsya program is recognized as being so called dead pixels. To search for such defects, tests are performed that are similar to those present in other representatives of this category of PZ.

The results of the research carried out can be sent to the site of the distributors of the program, which theoretically can help the collectors of the monitors.

At times, if there are suspicions about the correctness of the monitor’s robot, it would be wise to use one of the descriptions above software products. All stinks can give a good measure of testing the main parameters and help to detect whether or not there are defects, until they can be corrected.
