Flickering stripes on the monitor. Horizontal stripes on a computer monitor. What is this problem

User question

Hello!

Recently, stripes and ripples began to appear on my computer screen; the picture can sometimes twitch when passing a horizontal stripe.

This happens only in games. I tried reinstalling Windows, changing video drivers - no effect. These are artifacts on the video card (I was told so at the service center), and it needs to be changed. Or are there other options?

Good day!

In general, the presence of any distortion on the screen is a very alarming sign. Stripes and ripples can appear on the screen both due to problems with software and problems with hardware. In this article I will try to analyze the most basic things that you have to deal with, what can be done and taken to diagnose and find the cause (well, knowing the essence of the problem, you can often fix it on your own 😉).

What to do if ripples and stripes appear on the screen

STEP 1: check if the cable that connects the monitor to the computer is intact

The first thing I want to start with is the cable (perhaps this is somewhat banal, but still!). The fact is that it can be accidentally interrupted, chewed (by a pet, a cat, for example), etc.

And in general, many users do not always screw the VGA cable (for example) so that it does not come off. Often, simply adjusting the plug will solve the problem.

The photo below shows a damaged USB cable (the video cable is also damaged) ...

I'll add a couple more notes (regarding wires):

1. do not use long cables: if the length of your video cable is more than 3 meters, then the image on the screen may begin to distort (here, of course, a lot depends on the monitor);
2. see if the video cable is intertwined with the cable of the printer, telephone charger, cable TV, etc. The fact is that such elements can create interference (especially in the absence of shielding). Try placing the video cable away from other wires.

STEP 2: Pay attention when artifacts appear

Immediately after turning on the computer, i.e. they are there when entering the BIOS (), and when loading the OS, and after it has loaded, in all applications and games;

They appear only at a certain stage: for example, when loading the OS, and then disappear. Either when entering a particular game, or after some time spent in the game.

If in the first case, you can’t work on a PC at all and you need to eliminate the cause (you can ruin your eyesight), then in the second, for example, you can continue to work for quite a long time.

By the way, a simple observation like this will help determine the cause of the malfunction. For example, if you experience artifacts in only one game, then most likely the problem lies in the temperature, driver, or errors in the game itself.

I will also note that in the second case, the chances of restoring the PC/laptop (without material costs) are much greater!

STEP 3: Connect another monitor for diagnostics

This step is very important!

It will allow us to determine whether the artifact problem is related to a malfunction of the monitor, or to problems in the system unit (video card, motherboard).

Surely in every house where there is a PC, there is a TV, or another screen of some kind ✌. For example, if stripes appear on your laptop screen, connect it to a regular monitor and see if there are any distortions in the picture. Nowadays, any modern monitor can be easily and quickly connected to a computer using an HDMI cable (sold in almost every computer store).

In the photo below: a TV was connected to the laptop in order to see if there would be artifacts on the TV screen.

If there are no artifacts on the other screen and everything is fine: Then the problem is with the monitor. By the way, the problem of horizontal stripes appearing on CRT monitors used to arise quite often. In general, if the monitor itself is to blame for the streaks on the screen, then without having experience in repairing equipment, you cannot do without it.

If artifacts are present on another monitor: then the problem is probably in your computer: the problem is either with the software or with the hardware. We'll figure it out further...

STEP 4: Check the temperature of components (video card, CPU)

If there are stripes on the screen, first of all you need to look at the temperature of the video card. This can be done using special. utilities: .

An example in the screenshot below. We check the temperature in the GPU-Z utility (see the line "GPU Temperature").

In general, it is difficult to give an exact value critical temperature of the video card : Here you need to look at your specific model (use your manufacturer’s website). But in general, everything above 80 gr. Celsius - should alert you to a thorough check.

How to find out the permissible and critical temperature of your video card:

If overheating is suspected, it is recommended first clean your computer from dust , replace thermal paste. Dust often blocks ventilation openings, reducing air circulation. As a result, the temperature inside the system unit (laptop) begins to rise.

In laptops, by the way, it is easy to determine overheating if you put your hand near the ventilation holes (usually they are on the left): very hot air starts coming out of there, you can even get burned.

By the way, these utilities can measure the temperature during your game, tracking all the maximums and minimums. As soon as you notice the appearance artifacts– check what the temperature was.

To help!

1) Checking the video card for performance, testing for reliability and stability -

2) How to perform a stress test of the processor and the system as a whole, does it maintain frequencies, is there any overheating -

At all, pay special attention to temperature in hot summer months, when PC components often heat up to significant levels. To reduce the temperature in the system unit, simply remove the side cover and place a regular fan opposite.

There is a special one for laptops. stands that help improve air circulation (due to which it is possible to reduce the temperature by 5-10 degrees Celsius).

STEP 5: check and update your video card drivers

Drivers are everything...

Video card drivers can significantly affect picture quality (especially for 3D games).

For example, about 15 years ago I had several versions of drivers (official and not) for my Ati Radeon 8200 video card (if I’m not mistaken).

So, on the official drivers, on the most recent version, there was a glitch: some elements in games (in particular fire) were not shown - instead some squares and sometimes stripes were running... When I switched to another version of the drivers, everything worked, as it should be. Over time, the developers fixed this bug...

By the way, pay attention to how the computer will work when you remove the drivers: will there be stripes or ripples. Below is a link to an article that will help you remove and update drivers.

STEP 6: a few words about overclocking your video card

If you overclocked your video card, then it is likely that artifacts could appear (especially if you have never done this before and have no practical experience 👀).

Overclocking, in fact, is a whole science where you need to know and feel quite accurately how the hardware will behave (and, of course, there is always a certain risk).

Try resetting the frequencies and checking functionality. As a rule, if the problem was related to unsuccessful overclocking, it is solved.

Screenshot from the game Doom 3: pay attention to the white dots - the result of unsuccessful overclocking

In general, in most cases, if software overclocking fails, modern video cards, processors and memory themselves reset the settings to safe ones.

STEP 7: Check if the desired shader version is supported

Each video card supports a certain version of shaders (and games, by the way, also require a certain version, see the description for any game).

The point is: if you are trying to run a new game on a video card that is not new, it is quite possible that it does not support the necessary pixel shaders.

In general, usually, in this case, Windows will tell you that the game cannot be launched and an error will appear. But sometimes this doesn’t happen, and the game starts with distortions in the picture (especially now there are special shader emulators that allow you to run games on video cards that are not approved by the developers).

So if you have a problem in any one game, check : whether your video card model is included in the list of those supported by the game.

STEP 8: what else to pay attention to (hardware malfunction: video card, motherboard)

As a rule, when there are problems with hardware, artifacts appear everywhere: in the BIOS, when loading Windows, in games, in any other programs. In some cases, artifacts appear when the video card is heated to certain temperatures (for example, in games), etc. Most often, the reason lies in the detachment of the graphics chip, or overheating of the memory chips.

You can try the following: open the system unit, remove the video card and inspect it. Is there any visible damage on it? Most likely, there will be no visual signs of damage on it (statistics from personal experience).

However, if there is a lot of dust and high temperature readings in AIDA, Speccy, I recommend this:

1) First: clean the system unit from dust (can be blown out with a regular vacuum cleaner). .

2) Pay special attention to the video card contacts. Try cleaning its contacts with a regular eraser (clean the part that is inserted into the motherboard). Then blow through the entrance itself where it is inserted. With artifacts, this method helps, but not in all cases.

3) If the artifacts are not missing, it would be a good idea to check the video adapter on another work computer (however, I understand that this advice is unlikely to suit ordinary users; not everyone has 2 PCs at home...).

The photo below shows what normal capacitors look like (red arrows) and a swollen one (circled).

The motherboard/video card could also fail for reasons beyond your control. (i.e. without overclocking). For example, there was a power outage, a manufacturing defect, overheating, etc.

In general, for problems with iron (and lack of repair experience), it is better to contact the service center.

However, I want to warn you right away:

1. Some craftsmen may offer to repair and replace the chip on the video card. It is expensive (almost like a new video card), and it is unknown how the repair will be carried out, and how the video card will behave later. In general, I do not recommend it;

2. They may suggest warming up the video card (sometimes called hot). This topic is specific and extensive. But I want to say right away that such a repaired video card (at best) will not work for long, at most another six months. Then it ends anyway...

The most preferable option for these problems is to replace the video card with a new one. In the end, it's cheaper for the wallet... 👌

By the way, I would like to provide a couple of links to repairing a video card yourself:

Good day, dear readers and subscribers of my blog! A computer is a complex device where all elements are subtly interconnected. Poor quality work of one of the components can lead to equipment defects. In order for equipment to serve for a long time, it is necessary not only to care for it, but also to carry out diagnostics. This will allow you to identify the malfunction in a timely manner. Not every user will be able to do this on their own. Today I will tell you what to do if horizontal stripes appear on the monitor screen; how to remove them will be described below. It’s not uncommon for a problem to be caused by a technical breakdown, but the good news is that there’s usually nothing critical about it, which means it’s quite possible to handle it on your own.

A monitor is a means for displaying images on a display. It is closely connected with various computer components. Sometimes multi-colored stripes are a consequence of driver malfunction or a failure due to a virus. But software problems are rarely the root cause. More often, the reason is the incorrect connection of the PC nodes or the negative impact of one of them on the other.

Before starting diagnostics, it is worth checking what kind of defects are on the screen. If the picture is simply deformed or the colors are inverted, then the likely cause is the driver. Updating it is a simple task. It is best to download the latest version from the manufacturer's website. In the case where the screen is divided into strips or disintegrates into pixels, the reason is clearly in the hardware, and not in the software. Not all users know what to do in this case. Many people blame the video card, but that may not be the issue. Loose wires, overheating, dust are all possible sources of streaks. Therefore, first of all, I recommend disconnecting the computer from the network and starting sequential diagnostics of each element.

Monitor

Why might a monitor go bad? More often this is a physical impact - impact, increased moisture, exposure to sunlight on the matrix. Sometimes a power surge or network interference can damage the device. I recommend that all users connect the monitor to the electrical network through a surge protector. This is a good way to protect yourself. There is a nuance here. Sometimes an extension cord is used instead of a surge protector. When connecting different devices to it, noise may arise, which causes image distortion. In this case, we check the monitor by connecting it separately to the network. If this doesn't help, then we refer him to a friend. This is the easiest way to rule out damage to the monitor and start checking the rest of the computer.

Video card

The second node, which is responsible for displaying the image on the screen, is the video card. It processes incoming data and forms a picture. Like any device, it can burn out or become damaged. In addition, it is susceptible to heating, clogging and other unpleasant phenomena. Diagnosing a video card involves cleaning it from dust, checking the operation of the cooler, and lubricating it if necessary. It is also important to check the integrity of the connection wires. Often the reason lies in them. A system unit accidentally touched by your foot, wires coming loose from a connector - this is what distorts the image.

If this does not help, all wires are intact, the card does not heat up and is not dirty, then repeat the previous step. He removes the video card and goes to visit a friend again. The video card is working. So we are looking for the problem further.

Loops

Service employees often say that most breakdowns are solved by checking or replacing the connection wires. It was said above that you need to check how the video card is connected. However, it doesn’t hurt to consider the cables that connect other components. What is the test? We remove dust, check reliability and correct connections, inspect the wires for black spots, bends and fractures. Many users, over many years of using technology, do not look inside their system unit and do not suspect what kind of anarchy reigns there. Lots of wires mixed up with each other, covered in dust and sometimes cobwebs. All this will naturally affect work. To make your work easier in the future, I recommend that after purchase you inspect the system unit, connect the wires and try to lay them as evenly as possible. This will help avoid breakdowns in the future.

While connecting wires and checking connections, it would be a good idea to inspect the motherboard. There are a lot of elements on it and an untrained user is unlikely to find the problem himself. But it’s quite possible to notice minor defects. We are talking about burnt resistors. These are small protruding parts. Most often they are cylindrical in shape and can be in a variety of colors - black, green, red. A burnt transistor will be black and have traces of carbon deposits. The second sign of its failure is bloating. You shouldn’t change them yourself, but this is a signal that it’s time to take your PC to a service center.

Checking the monitor matrix

I mentioned above that the appearance of stripes is often the result of a hardware failure. But sometimes the nuances lie in the setup. First, you should try resetting your monitor to factory settings. It's very easy to do. There are buttons on the device's body that allow you to change gamma, brightness, and contrast. Among them there is always a factory reset button. With its help, the monitor returns to factory settings.

To understand the correct operation of the monitor itself, it would not be superfluous to check for the integrity of the matrix and the presence of hidden factory defects. This trick is often used by sellers to sell services to clients. It all sounds tricky and complicated, but in fact it is easy to do.

There are several ways:

• use of a special program;
• launch video;
• Microsoft tools.

Option 1 – download special software onto a flash drive and run it on your PC. There are a lot of programs, they take up little space, and they are quite easy to use.

Among the popular utilities:

These utilities will allow you not only to identify a dead pixel, but also check the matrix for color transitions and contrast. In general, the test consists of running the device to fill it with one color. The dead pixel will be highlighted in a different color. Special gradation images will help determine whether the colors are displayed correctly.

Option 2 – go to YouTube and enter the query “matrix test” into the search. The principle is similar, but you don’t need to download anything. Just launch the video, expand it to full screen, remove all unnecessary elements and watch carefully.

Option 3 – in the OS settings there are special items that allow you to customize your desktop. Among other things, you can select the background here. The verification process boils down to removing all elements from the desktop, the taskbar, and sequentially filling it with one color. In other words, this is a variation of the first option, you just have to dig a little into the settings. I do not recommend using this method, because it takes the longest. Suitable if there is no Internet and special utilities.

For those who decide to turn to this method, below is the sequence of actions:

• Personalization - Options.
• Background – Solid Color – Secondary Color.
• You need to choose white, gray, black, green, red, blue colors in turn. It is on them that the pixels are noticeable.
• We return to the Personalization menu and go to the Taskbar.
• Select "Automatically hide panel on desktop". Now she will hide off the screen on her own. To return it to its place, just move the cursor down.
• Last point. Right-click on the table and go to “View”. At the bottom, check “show desktop icons.”
• After completing these steps, nothing will remain on the desktop except the selected color. The action must be repeated for each of the above colors.

It is worth understanding that the software and methods listed above are a way to find a matrix defect. Repair in this case comes down to replacing the matrix. This is an expensive pleasure and can be done at a service center. I recommend performing a similar check for a new device. This should be done in a store, since if house pixels or stripes are detected, the monitor will be difficult to change quickly. Quality control will be required and this takes 21 days. It's unpleasant to buy a new monitor and wait 3 weeks for it to be replaced.

Settings

If the stripes on the screen are faintly visible, and they rather resemble incorrect display of colors, then you can try to fix this by adjusting. There are a number of special programs that allow you to achieve the most accurate display of colors.

The appearance of stripes on the screen is not a reason to buy a new monitor, video card or system unit. Often the defect can be fixed on your own, and I hope this article will help you do so.

If you want to stay informed, I'm in instagram, where I post new articles that appear on the site. And also there is my personal blog.

Thank you for your attention! See you again on my blog! Sincerely, Rostislav Kuzmin.

Technical equipment, new technologies, subtle but unnecessary interconnection of various elements - this is what modern progress has come to. We are, of course, talking about a computer, which has a lot of elements that require care and careful monitoring so that they work correctly and do not break. But not every one of us can do this, so we are faced with various problems that sometimes manifest themselves very strongly and cause a lot of inconvenience. We will mainly talk about technical problems that are difficult to diagnose, but it is quite possible to fix them yourself. And in this article we will look at where and why stripes appear on the monitor, which sometimes overshadow the entire picture on the screen. Fortunately, the problem is not always critical, so in most cases you can fix it yourself. And sometimes they indicate that the equipment has broken down and urgently needs to be replaced.

What is this problem?

Before you figure out where they came from on the monitor, it’s worth considering the problem itself, which in most cases is of a technical nature. Yes, a program failure, a virus and other problems, even an option related to drivers - none of this is the reason why defects appear on the monitor screen. This problem is a consequence of the negative influence of computer elements on the monitor or their incorrect interaction with each other. The problem is simple and critical, but this will become known only after a thorough diagnosis of the equipment. When this unpleasant situation occurs, various defective stripes begin to appear on the monitor, which bring with them a lot of trouble. Either they completely obscure the entire monitor, or they replace the colors, or the screen completely disintegrates into pixels.

Why does it occur?

If stripes appear on the monitor, this means that it is time to diagnose all equipment. You shouldn’t blame everything on the video card in advance, since it is not always the main cause of the problem. There may be other parts of your equipment involved that may contribute to this defect. It is worth completely excluding options that relate to programs or driver failures, since image distortion, which is also filled with extra stripes, is guaranteed to be a technical problem. Therefore, you can safely turn off your computer and start checking all your equipment for damage, dust, and much more.

Main causes of this problem

Vertical or horizontal stripes on the monitor may appear due to hardware failure or overheating. The incorrect interaction of various technical elements should also be taken into account. In addition, do not forget that the source of the problem can be dust and contamination of the cables, which are the connecting connection between various elements. Therefore, in order to establish the true causes, you need to conduct a series of diagnostic studies that will identify the true problem, and only then think about ways that will help get rid of this unpleasant situation. And it’s worth remembering that you shouldn’t immediately run to the service center, since in most cases you can get out of this situation with your own efforts. Well, if a technical problem is classified as critical, then there are no options - you will have to find among your friends those who have experience in troubleshooting such problems.

Video card

Horizontal stripes on the monitor and any defects in general cannot be caused primarily by a faulty video card. It is necessary to check whether it is working normally, whether the cooler on it is dusty, which can cause overheating of the equipment, and whether it is connected to the motherboard correctly, that is, whether the wires are damaged. Yes, the video card is the image processing center which can cause the problem. Therefore, if you suddenly notice that the board itself is working normally, you should definitely clean it of dust using cotton swabs. Then check its connectors and try to clean them. After this, check the wires for physical damage. If it doesn't exist, that's good news; If the wires are damaged, then the equipment will need to be replaced.

If no problems are found and everything is cleaned, it is worth carrying out another check, which consists of examining the technical features of the video card. It sounds complicated, but in reality everything is simple: you need to check the equipment on another computer. A friend can help you with this: just insert the video card into his computer and check if there are stripes on his monitor. If there are no stripes, then the problem is different; if there is a defect, then the problem is in that graphics hardware. This means you should contact service or buy a new video card.

Monitor malfunction

When vertical stripes appear on your monitor, do not panic. Just start checking your equipment. And it’s worth noting right away that the option with a monitor is also appropriate, although this element is not programmable. Any physical impact on the monitor can cause a lot of problems regarding image deformation. You can also note factors such as exposure to sunlight and exposure to high humidity on the monitor. To test this device, you do not need any special education; you just need to test it on another computer. Take advantage of this opportunity from a friend. If after connecting the bars on the monitor disappear, then the problem is in your computer; if the opposite result occurs, then you need to contact a specialized service, since such a problem cannot be corrected with your own hands.

Checking loops

Stripes can also mean that you probably have problems in the connections of the elements themselves, which can sometimes be either physically damaged or simply dusty. To check them, you need to carefully examine every millimeter of the cable for physical damage. Are there blackheads there? Is the cable itself positioned correctly? Does it have unnecessary bends? Is everything connected correctly? If this is possible, then it is worth checking them on another computer. In fact, the problem of cables is quite complex, and not everyone can fully check these wires, therefore, in order to diagnose such a problem instantly, you must always have several spare cables on hand, which can be replaced if necessary. If, after using fresh wire options, stripes continue to appear on the monitor, then you should look for the source of the problem in other equipment. And if there is no problem, then you have already solved it and can continue to enjoy the possibilities of the virtual space. It is worth remembering this nuance, since not many people know that this can also be the cause of an unpleasant situation.

Cleaning your computer

Damage to internal elements

But do not forget about the possible breakdown of internal devices, which can also cause defects on the screen. These elements mainly include traces and connecting elements on the motherboard. If you check them carefully, you will find that some of the strips have turned black and the resistors are swollen. It is this state of affairs that is the cause of the breakdown, which cannot be corrected by one’s own efforts. Therefore, if you find at least one of the elements listed, then you should replace the motherboard, since repairing it will no longer be possible.

How to solve this problem?

Stripes appeared on the monitor. How to solve this problem? Actually, we examined all possible solutions in this article, all of them are described above. First, you need to diagnose the equipment, clean the computer, since dust can cause overheating of important computer elements, and then draw conclusions and look for a way out of this unpleasant situation. A vertical stripe on the monitor or another graphic defect - all this is caused by the problems that we have discussed. As for the ways to eliminate them, we also examined them, in particular we mentioned the motherboard itself, which can serve as a source of negative impact. But, unfortunately, it is quite difficult to check it, so the only correct solution may be to contact a service center. Everything else can be checked and you can figure out what exactly is the reason for the defect appearing on the screen.

Service - guaranteed solution to the problem

A black line on the monitor, the image breaking up into pixels of different sizes, the image disappearing, incorrect color gamut - all this and much more indicates that there is a problem with your computer. This article allows you to fix them or diagnose them yourself. But it happens that your hands are simply afraid to touch anything there and generally disassemble the computer. It is in such cases, when you are not confident in your abilities, that a specialized service center will help you, where they will provide all the necessary services. For a fee, they will clean your computer and restore the normal image on the monitor. And if the breakdown is critical, then they will definitely tell you what exactly the problem is and how to fix it. Now it has become much easier to navigate this situation, which will undoubtedly serve as a positive new experience in terms of managing and monitoring computer technology.

Modern devices are becoming more comfortable to use every year. Agree, it’s nice to sit down to work at a computer with a monitor that has an ideal image and high-quality color rendition. But what if a line appears on the monitor? What if there are several of them? Before you act, you need to find the problem that is causing the streak or streaks.

Source

To be frank, not a single virus in the world, software failure, or even the lack of some drivers has ever been or will be the cause of streaks appearing on a computer or laptop screen. Stripes on the monitor are the result of the negative influence of some computer elements or even their incorrect interaction with each other.

Their character actually means a lot too. In some cases, they can be used to determine whether the problem is in the monitor itself and should be replaced, or in something else.

Causes

Problems with your monitor are a great time to check and clean your equipment. Professionals strongly recommend discarding any idea that the problem is in the drivers or the incorrect operation of some programs. This is just a technical question. Why is there such an emphasis on this? Because after the stripes appear, many people turn off the computer and think that it cannot be turned on. Since the problem is in the hardware, the machine continues to work. She's just waiting to be fully diagnosed.

Horizontal or vertical stripes on the monitor may appear due to overheating of the equipment or even breakdown.

Careful inspection

The monitor and computer are connected by one insidious cable - this is VGA. Many devices have holes on the sides of the connector so that this cable can be screwed tightly, but not always. That is why many people suggest starting the search for the cause of the band on the monitor by checking its connection. The cable should “sit” firmly and evenly, no wobbles, and so on. In addition, its surface must be free of any damage. If you see that the cable is pinched or torn, then you can safely change it - further use may be associated with the appearance of defects in the image.

Purity

If you encounter the problem described, ask yourself how long ago you cleaned your computer or laptop. And it's not just about running a vacuum cleaner over the device. It is important to regularly exercise computer cleaning or a laptop using a brush and a vacuum cleaner, or a good compressor, with a complete replacement of thermal paste in the necessary places.

This will allow the equipment not to heat up and operate as smoothly as possible. But what if the streaks on the monitor do not go away even after cleaning?

Loops

What is this? These are small cables that connect different parts of the computer to each other. Vertical or horizontal stripes on the monitor can be the result of incorrectly or poorly connected cables, and sometimes their complete breakdown.

First, check every millimeter for physical damage. There are quite a few reasons for their occurrence, so we will not focus on this. If you find a tear, a black dot, a suspicious bend, or anything else that raises doubts, check the cable on another device and, if your guess is confirmed, replace it with a new one.

Make sure that each cable is not only in its place (even an experienced master can confuse them), but also inserted correctly. This is quite painstaking work, but in some cases it helps to get rid of the problem.

The cause of incorrect operation may be oxidation of the contact surface of the cable. To fix it, remove the cable from the connector and wipe the contacts with a regular eraser.

Video card

The video card is the processing center for all images. It is malfunctions in the operation of this small part of the device that most often cause various stripes on the monitor. In order to exclude the video card as the cause of the ripples, you need to check whether it is working correctly.

The check includes:

• cleaning the board from dust using cotton swabs;
• removing and returning the board and all connecting cables;
• checking all wires, which must be intact, without various creases, and so on;
• working with a cooler that should be free of dust and foreign objects.

If after all the manipulations described above it seems that the card is working properly, try connecting it to another computer, for example, to your friend or relative’s device. If the same stripes appear when you connect your board to another computer, you have found the cause of the described problem. What to do? Take your computer to a service center or buy and install a new video card yourself that matches the parameters of your computer.

However, streaking is not always a problem with the video card. Sometimes it's the monitor itself.

Monitor is faulty

Horizontal stripes on your monitor may be caused by the display device itself. In some cases, this unpleasant pattern appears due to physical damage. What is it about? These are falls of the monitor itself, impact of any part of it with something or something, and so on. The streaks that result from this are often colored.

In addition to direct physical impact in the form of shocks, direct sunlight, high humidity or temperature have a negative impact on the monitor. Any violation of operating rules can also cause stripes.

How can you tell if a vertical line on your monitor is a problem with the screen itself? As one famous hero said: “Elementary, Watson!” You just need to connect the monitor to another computer. You don't need any skills or talents for this!

To understand how to “treat” a device, you need to know how it works.

Monitor design and repair

As you know, the image itself is a set of colored dots. In order to accurately display them on the screen, special chips are built into the monitor that give commands to the pixels and they turn on or, conversely, turn off. These “drivers” are located on the display matrix and each of them is responsible for its own zone.

The matrix cable, through which the signal to reproduce the picture is transmitted, is attached with a special substance - this is a kind of glue with a conductive effect. It is this part of the device that is the weak link, which most often fails. Once the traces peel off from the driver on the cable, thin vertical lines appear on the monitor.

In some cases, adjusting the monitor brightness or making minor repairs can help. The latter includes gluing, or rather, pressing the upper part of the monitor (the cable to the matrix body using, for example, a spacer). But this is only a short-term solution to the problem.

Unfortunately, repairing a broken monitor is not cheap. Why? Thin vertical stripes on the monitor indicate an imminent replacement of the matrix, the cost of which is 80% of the total price of the device. Some people find it makes more sense to simply purchase a new monitor.

Examine the monitor itself

Although at the beginning of the article it was said that stripes are a physical problem, there is a case when the problem is in the monitor itself. What are we talking about? Black line on the monitor from any side - this is an incorrect setting of the unit. This problem happens quite often and does not pose any danger.

To cure your monitor from this “illness”, you can use the simplest advice. Which one? Use the monitor buttons. Any device has an automatic setup button, which will solve this problem in a matter of moments. To be sure to press the right key, study the instructions for your device. This will allow you to determine what resolution your monitor should work with. If the system is set to an inappropriate resolution or aspect ratio, banding can be eliminated simply by correctly adjusting the parameters of the image output by the video card.

By the way, using some other buttons you can adjust the brightness of the monitor that is optimal for your eyes.

"Dead pixel

In addition to unpleasant vertical or horizontal stripes on the monitor, many people are really annoyed by the so-called dead pixels. Nowadays, a number of methods have been created that in some cases can save the situation.

1. "Massage". Hearing an offer to give a damaged pixel a massage, many will raise one eyebrow and start calling a doctor for the person who suggested it. Nevertheless, on various forums you can often come across suggestions from users to gently rub the pixel with a cotton swab for 10-15 minutes. There is practically nothing on the Internet about whether this method works. Often it can't help, but it's still worth trying without trying too hard.
2. A program for adjusting the monitor and eliminating “dead” pixels. This option is more professional, although it does not always solve the tasks assigned to it. The principle of operation of programs for eliminating a broken element is to fill it with pixels of various colors and shades. According to the developers, the problem should disappear from the monitor after half an hour of running the program. Constant changes in the parameters of the signal output to the pixel should act as a “wedge”, knocking it into normal operation.
3. Combination of both methods.

If none of this works, you have two options - put up with it or buy a new monitor.

Setting up equipment

In fact, it’s not just the black line on the monitor that can interfere with comfortable work at the computer. If your device does not display colors correctly, you may experience some trouble. For example, if your work is related to photography, then the colors that an inaccurate monitor shows when displaying the picture on a normal screen can ruin your reputation as a specialist. And if you use a computer for entertainment, then your eyes will get tired many times faster. So what should you do?

• Adobe Gamma. This program was previously part of Photoshop. Why this is not the case now is partly clear from its design, because it evokes warm feelings of nostalgia for CRT monitors. It was written for them. Nevertheless, some people consider this program excellent and suitable for use with modern information display systems, and no one is going to argue with them.
• Atrise lutcurve. An inexpensive program in Russian, which is understandable thanks to numerous tips from the author.
• PowerStrip. The advantage of this program is considered to be the ability to work with a wide variety of video cards with access to more than five hundred parameters of this part of the computer. With it you can adjust not only color rendition, but also the clock frequency and performance of the monitor.

These are just a few options that can improve your life. By the way, in some cases they can also eliminate streaks on the monitor.

conclusions

Whatever one may say, the comfort of using not only the monitor, but the entire computer as a whole is the user’s job. This article clearly shows the relationship between regular computer maintenance and the years of its operation, because with a clean processor or video adapter heatsink, the likelihood of equipment overheating is significantly reduced.

In addition, it is very important to ensure that the monitor itself is not subjected to any tests such as exposure to direct sunlight, heating equipment, high humidity, and so on.

If it so happens that stripes have appeared on your monitor, you have taken out all the cables, put them in place, but the situation has not changed, and you have no idea what and how it works in the computer, we strongly recommend that you contact a service center. This option will make your life much easier.
