The appearance of stripes on a laptop screen falls into the category of complex breakdowns. And if you hope that you will deal with this problem within a few minutes, then unfortunately, this is not the case.
Difficulty of diagnosis
Diagnosing such a problem on a laptop is much more difficult than on a regular computer. This is due, first of all, to the design features of laptops and their more complex structure.
Stripes on a laptop screen can be horizontal, vertical, black, white or colored, and the reasons for their appearance usually lie in problems with the latter’s hardware devices.
You can also see ripples on the screen, skewed images, mirror color rendition (black - gray, red - green, etc.), displaying the image as a negative.
Reasons for stripes appearing on a laptop screen
Let's look at the reasons for this phenomenon:
- 1. The simplest reason in this situation is overheating of the video card.
For example, this situation happened with the Dell M5110 laptop. In the lower part, in the area of the discrete video card (there are two of them), it got so hot that the leatherette on which it stood began to melt and stick to it.
As a result, the periodic appearance of colored stripes and ripples on the screen. The problem was partially solved by purchasing a stand with laptop coolers. Stripes appear, but very rarely.
- 2. Complete failure of the video card.
As a rule, the main reason for such a breakdown is also overheating or hardware failure. The power supply copes well with surges in the power supply, so this reason is unlikely.
In such a situation, either stripes appear on the screen even when the OS is loading, or the laptop does not start at all.
This problem can be solved by repairing or upgrading the video card. This is not easy to do on a laptop; you need to have the skills of at least a novice electronics engineer. But we will talk about these points further.
- 3. The system board has failed.
The situation is the same as point 2; diagnosing the problem is difficult, but possible. We will talk about this further.
- 4. The cable has failed.
From the motherboard to the matrix there is a special cable through which the signal is transmitted.
Poor contact at the connection point, burnout or fracture of the cable can cause interruptions in signal transmission to the matrix, hence the appearance of stripes.
- 5. Problems with the matrix, its failure.
The situation is critical, there is only one way out, the matrix requires replacement.
In this situation, it is a rare case when reinstalling or updating the video card drivers helps, and hoping that this will help is not worth it, it is indeed a rare case.
Diagnosing problems
The most important task in all this is to correctly diagnose the cause of the problem.
A complete diagnosis of the reasons for the appearance of stripes on a laptop screen can only be carried out in service centers using special equipment.
But initial diagnosis, which can also tell us a lot, is also possible at home.
Using an additional monitor
An additional monitor can be connected to a laptop via a connector VGA.
There can be two results:
- Everything will be displayed normally on the additional monitor;
- Similar bars will appear as on the laptop screen.
The result of step 1 tells us that the laptop’s video card is working, problems should be looked for in the matrix and cable of the laptop.
Result 2 tells us that there are problems with the motherboard and video card. In both cases, repairs are inevitable.
Checking the matrix
- Checking the matrix at home is possible by partially deforming it.
- Try not to push the monitor screen too much in areas where there are the largest number of stripes.
- Then, carefully, with both hands, try to slightly bend the screen in a horizontal plane.
- In both cases, notice how the colors of the stripes change, their contrast and brightness.
- If changes are visible, then the cause of the breakdown is in the matrix or cable.
When do you need to change the laptop matrix?
We replace the laptop matrix in cases:
- Provided that a parallel connected monitor is working. If, when the matrix is deformed in the horizontal and vertical planes and its surface is pressed inward, the color rendition of the stripes changes, the stripes disappear and reappear.
- The presence of stripes is observed at all stages of computer boot - BIOS, WINDOWS.
- Ripples appeared on the screen, wide white or multi-colored stripes were visible.
- The matrix displays the image in negative or the colors are being substituted, for example, it should be red, but green is displayed, blue is yellow, black is light gray, etc.
Checking the cable
- The cable is flexible and this is understandable, because the laptop screen cannot be in the “stowed” position all the time, and this is not a computer. Deformation of the cable occurs constantly, and therefore the probability of its failure is high.
- Slowly opening and quickly closing the lid and vice versa, observe how the strips “behave.” Any changes on the monitor screen indicate that the source of the problem is the cable.
What does the matrix cable look like for the Asus X51RL laptop.
When do you need to “deal” with a loop?
Condition – a parallel connected monitor shows a clear picture.
- It is necessary to repair, or better yet change, the matrix cable in cases where the image on the screen is unclear, ripples, flickers periodically, or has a large number of colored and white lines.
- While the laptop is booting and running, there are vertical columns of white pixels on the screen.
- Opening and closing the lid “revitalizes” all these errors on the screen.
Video card
The video card requires attention if the laptop screen and a parallel connected monitor display a picture with multi-colored lines, and other errors in the image are also duplicated.
- At the very beginning of the computer boot, there are no horizontal, vertical, black, white or colored stripes, but when Windows boots, the stripes appear.
- When Windows boots, the image disappears and a black screen appears.
- The laptop gets very hot in the area where the video card is located (the motherboard may also get hot).
Motherboard
- The motherboard requires attention in the same cases as the video card (see above).
- If replacing the cable, video card and matrix did not correct the situation.
- Now let's look at ways to solve the problem with stripes on a laptop screen.
Ways to solve the problem
Plume
Problems with the cable going to the matrix most often arise in older laptop models. In new models, manufacturers are already using more advanced design solutions, thanks to which the cables last a very long time.
This is the difficulty of repair; finding such a cable for an old laptop model will be difficult, but possible.
Before you go to the radio market or electronics flea market, write down the model of the matrix, without this there is no way.
The service center is unlikely to want to sell you such a rare “spare part”, and no one will want to lose a client, but what if you decide to give the laptop to them for repair.
If you find the cable you need, you’re lucky; if not, you can try to do it yourself.
To do this, you will need some minor electronics skills, a soldering iron, solder, rosin, a tester and, most importantly, MGTF type wire.
To ring a loop with a tester, you will have to reach both ends. The repair technology is simple as hell.
We call, find a break (if there is one), and instead of the broken wire, solder a duplicate wire parallel to it.
If there is no break, then the problem lies in more expensive components.
Motherboard
The system board may not fail completely. As a result of overheating of its individual section, the microchip or bus responsible for exchanging data with the video card may fail.
Also pay attention to the PCMCIA slot where the video card is inserted, to see if there are any burnt or oxidized contacts there. After all, they pour tea and coffee onto laptops.
But in any case, repairs cannot be avoided. But first order diagnostics, and if you are offered to re-solder any chip or clean the contacts, you can still agree to this.
Complicated repairs to a burnt-out motherboard are not worth it; it’s easier to replace it with a new one.
Video card
The situation is similar with a video card. A video chip is soldered onto it, which can fail as a result of overheating.
Here you need to follow three paths. Let's consider them in descending order, with respect to the high cost and reliability of the work.
- Replace this chip immediately (expensive, but reliable);
- Dismantle and reinstall the same chip - Rebowling (in most cases it gives results);
- Warming up the chip (pay less, but in 99% of cases the problem will recur after a while).
Everyone decides for themselves which method to use.
Burnt.
Do not forget, before leaving your laptop for service, to agree with the technician on the prices for all types of work performed, or better yet, agree on their contract.
Also, do not forget about the certificate of work performed, which indicates the date of repair, what was changed or what was repaired, as well as the warranty.
Bottom line
Of course, it is impossible to describe all situations when stripes appear on a laptop screen.
The problem is so specific and individual that it requires separate study in each case.
It all depends on the laptop model, matrix type, design features and analysis of how often such problems appear on this particular model.
But if we take in percentage terms what was most often repaired and changed in this situation, then cases with matrix replacement are about 40%, cable replacement or repair is about 20%, video cards are about 20%, motherboards are approximately 20% (with taking into account the failure of the integrated video card).
As we see, in most cases it is necessary to change the matrix, but this is not a cheap undertaking; if the cost of replacing it exceeds 50% of the price of a new laptop, then there is no point in such repairs, it is easier to buy a new one.
But everyone decides for themselves. We wish that your laptop screens always delight you with clear and bright images. Good luck.
Hello.
While many errors and problems on the computer can be tolerated, defects on the screen (the same stripes as in the picture on the left) cannot be tolerated! Not only do they interfere with your view, but they can also damage your eyesight if you work on such an image on the screen for a long time.
Stripes on the screen can appear for various reasons, but most often they are associated with problems with the video card (many people say that artifacts have appeared on the video card...).
Artifacts mean any distortion of the image on a PC monitor. Most often, they appear as ripples, color distortion, stripes with squares across the entire area of the monitor. So what to do with them?
Right away I want to make a small disclaimer. Many people confuse artifacts on the video card with dead pixels on the monitor (a clear difference is demonstrated in Fig. 1).
A dead pixel is a white dot on the screen that does not change color when the picture on the screen changes. Therefore, it is quite easy to detect by filling the screen with different colors one by one.
Artifacts are distortions on the monitor screen that are not related to problems with the monitor itself. It’s just that the video card sends such a distorted signal to it (this happens for many reasons).
There are software artifacts (related to drivers, for example) and hardware artifacts (related to the hardware itself).
Software artifacts
As a rule, they appear when launching some 3D games or applications. If you experience artifacts when loading Windows (also in), most likely you are dealing with hardware artifacts (about them later in the article).
There are a lot of reasons for the appearance of artifacts in the game, but I will analyze the most popular ones.
1) Firstly, I recommend checking video card temperature at work. The thing is that if the temperature has reached critical values, then everything is possible, from distortion of the picture on the screen to failure of the device.
You can read about how to find out the temperature of a video card in my previous article:
If the temperature of the video card exceeds the norm, I recommend cleaning the computer from dust (and paying special attention to the video card when cleaning). Also pay attention to the operation of the coolers; perhaps one of them is not working (or is clogged with dust and does not spin).
Overheating most often occurs in hot summer months. To reduce the temperature of the system unit components, it is even recommended to open the unit cover and place a regular fan opposite it. This primitive method will help to significantly reduce the temperature inside the system unit.
How to clean your computer from dust:
2) The second reason (and quite common) is drivers for video card. I would like to note that neither new nor old drivers provide a guarantee of good performance. Therefore, I recommend updating the driver first, and then (if the picture is just as bad) rolling back the driver or installing an even older one.
Sometimes using “old” drivers is more justified, and for example, they more than once helped me enjoy a game that refused to work normally with new versions of drivers.
How to update drivers with just 1 click:
3) Update DirectX and .NetFrameWork. There is nothing special to comment here, I will give a couple of links to my previous articles:
4) Lack of shader support will almost certainly result in artifacts on the screen ( shaders- these are a kind of scripts for a video card that allow you to implement various special functions. effects in games: dust, ripples on the water, particles of dirt, etc., everything that makes the game so realistic).
Usually, if you try to run a new game on an old video card, you get an error saying that it is not supported. But sometimes this does not happen, and the game runs on a video card that does not support the required shaders (there are also special shader emulators that help run new games on old PCs).
In this case, you just need to carefully study the system requirements of the game, and if your video card is too old (and weak), then, as a rule, you won’t be able to do anything (except overclocking...).
5) At overclocking a video card Artifacts may appear. In this case, reset the frequencies and return everything to its original state. In general, overclocking is a rather complicated topic and if not handled correctly, you can easily damage the device.
6) A glitchy game can also cause image distortion on the screen. You can usually find out about this by looking at various player communities (forums, blogs, etc.). If there is such a problem, then you are not the only one who will encounter it. Surely, they will also suggest a solution to this problem (if there is one...).
And hardware artifacts
In addition to software artifacts, there may also be hardware artifacts, the cause of which is poorly functioning hardware. As a rule, you will have to observe them absolutely everywhere you are: in the BIOS, on the desktop, when loading Windows, in games, any 2D and 3D applications, etc. The reason for this, most often, is the detachment of the graphics chip; less often, there are problems with overheating of the memory chips.
For hardware artifacts, you can do the following:
1) Replace chip on video card. Expensive (relative to the cost of the video card), it’s tedious to look for an office that will carry out repairs, it takes a long time to search for the right chip, and other problems. It is still unknown how this repair will be carried out for you...
2) Trying on your own warm up the video card. This topic is quite extensive. But I will say right away that such a repair, even if it helps, will not help for long: the video card will work from a week to six months (sometimes up to a year). You can read about warming up the video card from this author: http://my-mods.net/archives/1387
3) Replacing the video card with a new one. The fastest and simplest option, which sooner or later everyone comes to when artifacts appear...
That's all for me. Good PC work to everyone and fewer errors :)
Let's talk about stripes on the monitor screen; what to do if vertical or horizontal lines suddenly appear on it? Some individuals advise immediately running to the “masters”. They say the problem is complex, and any intervention will only make it worse. Moreover, the price of such a service is about 1000 rubles. But why pay!? Let's solve the problem ourselves!
First, you need to determine the cause of stripes on your computer screen.
Alas, but the chance of a software error is MI-NI-MA-LEN. It's a matter of hardware. So check:
A) Are hdmi and other cables connected well? Are they damaged?
I recommend unscrewing everything and blowing it out (even when you are sure that everything is in order). Also make sure that there are no serious deformations on the blue cable (which leads to the monitor). They could very well be the culprit behind the irritating stripes.
B) The video card is damaged due to overheating.
Naturally, you won’t see this visually. There are practically no swellings or other visual signs of damage on it. Indirectly, this can be indicated by a dust-clogged cooling system and Aida temperature readings.
There are two things you can do here:
1. Remove the video card, clean its contacts (especially the part with which it is inserted into the motherboard). It’s extremely rare, but it helps, I’m serious: the chances are slim.
2. check it on another, 100% working computer.
But there may be problems with either of them, the third reason is:
B) Motherboard malfunction.
Stripes on the monitor screen may be due to this. Whether the voltage jumped, whether there was overheating or a manufacturing defect is not so important. The fact is that this happens everywhere. In addition, if when examining it (there is no need to pull it out of the system unit) swelling of the condensers (such barrels) or their “blackening” is visible, then with a 90% chance you have found the cause of your misfortune.
A faulty matrix is the cause of streaks on the screen.
This is sadness. You can't fix it yourself. Unless to carry out diagnostics - connect the monitor to a laptop or other PC. The stripes remain - take the monitor to the service center. I’ll also tell you one “interesting” method.
At your own risk: lightly press (as if you were gently massaging the body) on the monitor that is turned on, preferably in the area of the stripes. Now watch out: if the location of the bars changes, the reason is in the monitor matrix or HDMI cable.
Stripes on the laptop screen.
Do the lines/ripples change their location when the laptop is opened or closed? Move it back and forth at different speeds. Are you seeing the above? The matrix cable is faulty.

Horizontal stripes on a computer monitor
Technical equipment, new technologies, subtle but not necessary 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 the vertical stripes appeared 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, in general, any defects on the monitor screen can 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 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 on the monitor screen 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 tracks 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 is a 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.

Stripes appeared on the monitor screen
Stripes on the screen of a laptop or computer can appear due to various reasons such as overheating of the video card, a faulty or poorly attached cable, a change in screen resolution on the computer that does not support the monitor, drivers for the video card are not installed, the monitor matrix is damaged, or the video card is damaged.
How to remove stripes on the screen
If your friend has a computer, then this makes it easier to find the cause of streaks on the computer monitor screen. First you need to find out why stripes appear on the monitor screen, and then try to eliminate them.

Color stripes on the monitor screen
Color stripes on the monitor are one of the most characteristic signs of a device malfunction. They usually appear immediately after turning on the PC and look different:
- Multi-colored stripes of different widths, similar to the northern lights, which completely cover the image on the monitor.
- Pink, purple, blue or yellow vertical stripes on the monitor screen, alternating with normal areas and located at the same distance.
- Red, blue or green stripes appear on the monitor screen, located horizontally or vertically and occupying the entire surface of the screen or individual rectangular areas. As a rule, the image in these places is distorted.
- Thin gray stripes are visible on the monitor.
- A wide white stripe appeared, occupying more than half of the total area on the monitor.
These are the most typical cases of monitor malfunction, which can have many more combinations and options. However, color stripes on the monitor themselves are a serious reason to think about repairs, because even barely noticeable stripes are harbingers of a major breakdown that can completely damage the monitor.
What to do if color stripes appear on the monitor?
Typically, the appearance of stripes on the screen is associated with a broken video card or an incorrectly working driver. However, if all components of the PC system unit are known to be in good working order, then we are talking about a serious problem in the design of the monitor itself, which cannot be eliminated without the help of a specialist.
Most often, artifacts in the form of multi-colored stripes on the screen are caused by a direct breakdown of the monitor matrix. This may be the result of a power surge, mechanical damage, or ordinary wear and tear. In this case, the problem is solved by replacing the matrix.
The cable connecting the matrix and the video controller on the control board, or the electrodes powering the screen pixels, may also fail. Often, colored stripes appear on the monitor screen when the video signal is poor due to dusty or damaged contacts.
Below are some typical cases associated with multi-colored stripes on the monitor screen and possible reasons for their appearance. Please note that the description of the problem does not take into account the performance of the video card. It should also be remembered that the described malfunctions are not the only possible ones.
Reasons for the appearance of stripes
| Rectangular areas consisting of a cluster of short, thin vertical or horizontal stripes of red or green color. The video signal contacts may be dusty or damaged, the tracks on the control board have peeled off, or the video controller cable or VGA wire may be damaged. |
| A wide white stripe occupying a third or more than half of the screen surface. Most likely, the matrix has failed. Needs replacement. |
| Yellow vertical bars spaced evenly across the screen. If the problem periodically disappears and appears, the matrix decoder conductors may become detached. |
| Wide purple or pink stripe on the monitor. The matrix controller is probably faulty. The problem is often observed on new monitors and may be the result of a manufacturing defect. |
| Thin vertical stripes of blue or light blue. One of the cable contacts or the video controller may be damaged. |
| Light flickering stripes, barely noticeable on the screen. The problem may be due to a faulty VGA cable or a low-quality surge protector powering the monitor. |

Stripes appear on the laptop screen, what should I do?
The appearance of stripes on a laptop screen falls into the category of complex breakdowns. And if you hope that you will deal with this problem within a few minutes, then unfortunately, this is not the case.
Difficulty of diagnosis
Diagnosing such a problem on a laptop is much more difficult than on a regular computer. This is due, first of all, to the design features of laptops and their more complex structure.
Stripes on a laptop screen can be horizontal, vertical, black, white or colored, and the reasons for their appearance usually lie in problems with the latter’s hardware devices.
Vertical stripes.
Horizontal.
You can also see ripples on the screen, skewed images, mirror color rendition (black - gray, red - green, etc.), displaying the image as a negative.
Ripples in areas of the screen.
Reasons for stripes appearing on a laptop screen
Let's look at the reasons for this phenomenon:
- 1. The simplest reason in this situation is overheating of the video card.
For example, this situation happened with the Dell M5110 laptop. In the lower part, in the area of the discrete video card (there are two of them), it got so hot that the leatherette on which it stood began to melt and stick to it.
As a result, the periodic appearance of colored stripes and ripples on the screen. The problem was partially solved by purchasing a stand with laptop coolers. Stripes appear, but very rarely.
- 2. Complete failure of the video card.
As a rule, the main reason for such a breakdown is also overheating or hardware failure. The power supply copes well with surges in the power supply, so this reason is unlikely.
In such a situation, either stripes appear on the screen even when the OS is loading, or the laptop does not start at all.
This problem can be solved by repairing or upgrading the video card. This is not easy to do on a laptop; you need to have the skills of at least a novice electronics engineer. But we will talk about these points further.
- 3. The system board has failed.
The situation is the same as point 2; diagnosing the problem is difficult, but possible. We will talk about this further.
From the motherboard to the matrix there is a special cable through which the signal is transmitted.
Poor contact at the connection point, burnout or fracture of the cable can cause interruptions in signal transmission to the matrix, hence the appearance of stripes.
- 5. Problems with the matrix, its failure.
The situation is critical, there is only one way out, the matrix requires replacement.
In this situation, it is a rare case when reinstalling or updating the video card drivers helps, and hoping that this will help is not worth it, it is indeed a rare case.
Diagnosing problems
The most important task in all this is to correctly diagnose the cause of the problem.
A complete diagnosis of the reasons for the appearance of stripes on a laptop screen can only be carried out in service centers using special equipment.
But initial diagnosis, which can also tell us a lot, is also possible at home.
Using an additional monitor
An additional monitor can be connected to a laptop via a VGA connector.
There can be two results:
- Everything will be displayed normally on the additional monitor;
- Similar bars will appear as on the laptop screen.
The result of step 1 tells us that the laptop’s video card is working, problems should be looked for in the matrix and cable of the laptop.
Result 2 tells us that there are problems with the motherboard and video card. In both cases, repairs are inevitable.
Checking the matrix
- Checking the matrix at home is possible by partially deforming it.
- Try not to push the monitor screen too much in areas where there are the largest number of stripes.
- Then, carefully, with both hands, try to slightly bend the screen in a horizontal plane.
- In both cases, notice how the colors of the stripes change, their contrast and brightness.
- If changes are visible, then the cause of the breakdown is in the matrix or cable.
When do you need to change the laptop matrix?
We replace the laptop matrix in the following cases:
- Provided that a parallel connected monitor is working. If, when the matrix is deformed in the horizontal and vertical planes and its surface is pressed inward, the color rendition of the stripes changes, the stripes disappear and reappear.
- The presence of stripes is observed at all stages of computer boot - BIOS, WINDOWS.
- Ripples appeared on the screen, wide white or multi-colored stripes were visible.
- The matrix displays the image in negative or the colors are being substituted, for example, it should be red, but green is displayed, blue is yellow, black is light gray, etc.
Checking the cable
- The cable is flexible and this is understandable, because the laptop screen cannot be in the “stowed” position all the time, and this is not a computer. Deformation of the cable occurs constantly, and therefore the probability of its failure is high.
- Slowly opening and quickly closing the lid and vice versa, observe how the strips “behave.” Any changes on the monitor screen indicate that the source of the problem is the cable.

When do you need to “deal” with a loop?
Condition – a parallel connected monitor shows a clear picture.
- It is necessary to repair, or better yet change, the matrix cable in cases where the image on the screen is unclear, ripples, flickers periodically, or has a large number of colored and white lines.
- While the laptop is booting and running, there are vertical columns of white pixels on the screen.
- Opening and closing the lid “revitalizes” all these errors on the screen.
Video card
The video card requires attention if the laptop screen and a parallel connected monitor display a picture with multi-colored lines, and other errors in the image are also duplicated.
- At the very beginning of the computer boot, there are no horizontal, vertical, black, white or colored stripes, but when Windows boots, the stripes appear.
- When Windows boots, the image disappears and a black screen appears.
- The laptop gets very hot in the area where the video card is located (the motherboard may also get hot).

Motherboard
- The motherboard requires attention in the same cases as the video card (see above).
- If replacing the cable, video card and matrix did not correct the situation.
- Now let's look at ways to solve the problem with stripes on a laptop screen.

Ways to solve the problem
Plume
Problems with the cable going to the matrix most often arise in older laptop models. In new models, manufacturers are already using more advanced design solutions, thanks to which the cables last a very long time.
This is the difficulty of repair; finding such a cable for an old laptop model will be difficult, but possible.
Before you go to the radio market or electronics flea market, write down the model of the matrix, without this there is no way.
The service center is unlikely to want to sell you such a rare “spare part”, and no one will want to lose a client, but what if you decide to give the laptop to them for repair.
If you find the cable you need, you’re lucky; if not, you can try to do it yourself.
To do this, you will need some minor electronics skills, a soldering iron, solder, rosin, a tester and, most importantly, MGTF type wire.
To ring a loop with a tester, you will have to reach both ends. The repair technology is simple as hell.
We call, find a break (if there is one), and instead of the broken wire, solder a duplicate wire parallel to it.
If there is no break, then the problem lies in more expensive components.
Motherboard
The system board may not fail completely. As a result of overheating of its individual section, the microchip or bus responsible for exchanging data with the video card may fail.
Also pay attention to the PCMCIA slot where the video card is inserted, to see if there are any burnt or oxidized contacts there. After all, they pour tea and coffee onto laptops.
But in any case, repairs cannot be avoided. But first order diagnostics, and if you are offered to re-solder any chip or clean the contacts, you can still agree to this.
Complicated repairs to a burnt-out motherboard are not worth it; it’s easier to replace it with a new one.
Video card
The situation is similar with a video card. A video chip is soldered onto it, which can fail as a result of overheating.
Here you need to follow three paths. Let's consider them in descending order, with respect to the high cost and reliability of the work.
- Replace this chip immediately (expensive, but reliable);
- Dismantle and reinstall the same chip - Rebowling (in most cases it gives results);
- Warming up the chip (pay less, but in 99% of cases the problem will recur after a while).
Everyone decides for themselves which method to use.

Burnt.
Do not forget, before leaving your laptop for service, to agree with the technician on the prices for all types of work performed, or better yet, agree on their contract.
Also, do not forget about the certificate of work performed, which indicates the date of repair, what was changed or what was repaired, as well as the warranty.
Bottom line
Of course, it is impossible to describe all situations when stripes appear on a laptop screen.
The problem is so specific and individual that it requires separate study in each case.
It all depends on the laptop model, matrix type, design features and analysis of how often such problems appear on this particular model.
But if we take in percentage terms what was most often repaired and changed in this situation, then cases with matrix replacement are about 40%, cable replacement or repair is about 20%, video cards are about 20%, motherboards are approximately 20% (with taking into account the failure of the integrated video card).
As we see, in most cases it is necessary to change the matrix, but this is not a cheap undertaking; if the cost of replacing it exceeds 50% of the price of a new laptop, then there is no point in such repairs, it is easier to buy a new one.
But everyone decides for themselves. We wish that your laptop screens always delight you with clear and bright images. Good luck.
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 thoroughly clean your computer or laptop using a brush and a vacuum cleaner, or a good compressor, and completely replace the 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? A black stripe on the monitor on either side 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.
- "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.
- 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.
- 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.
A monitor is the most important device for working with a computer, which allows you to see all the actions on the screen. Unfortunately, the monitor does not always please with its correct operation. Below we'll look at what causes vertical stripes to appear on your monitor, and whether there's anything you can do about it.
As a rule, suddenly appearing vertical stripes on the screen of users’ computers occur for two groups of reasons: software and hardware. In the first case, the software installed on the computer was to blame, and in the second, there were problems with the monitor itself or its connection to the system unit.
A little advice: before you start moving on to ways to solve the problem, try connecting your monitor to another computer - this way you can understand whether the problem is the computer itself, or a malfunction in the monitor.
Software problems
Reason 1: missing video card drivers
If you just reinstalled Windows or updated your video card drivers, but then encountered vertical stripes on your monitor screen, you can assume there are problems with the drivers.
To solve this problem, you will need to install fresh video card drivers. First of all, open the menu "Control Panel" and go to the section "System".
In the left area of the window, click on the item "Device Manager".
Expand the tab "Video adapters". If the name “VGA adapter” or the name of your video card appears next to it, but with a yellow exclamation mark, this indicates that the drivers are not working. If the drivers have been installed, right-click on the graphics adapter and select "Delete".
A confirmation window will appear on the screen, where you will need to check the box next to "Uninstall driver programs for this device".
Once the removal is completed successfully, you will need to restart your computer. From this moment, you can start downloading and installing the latest version of video card drivers (if you haven’t worked with video card drivers at all after installing Windows, you will immediately need to proceed to downloading them, without the preliminary removal procedure described above).
You can download video card drivers from the official website of the manufacturer of your graphics adapter (specifically for your model). If you are the owner of a laptop, then the graphics drivers will be downloaded from the laptop manufacturer’s website.
After downloading the required driver distribution, you will need to run it by installing it like any other program, and then be sure to restart the computer.
Reason 2: incorrect resolution settings
The problem with vertical stripes may arise because the computer settings are set to the wrong resolution.
To check this, right-click on any free area of the desktop and select the item from the context menu that appears. "Display Options".
Please note that further actions are discussed using Windows 10 as an example. If you have a different version of the operating system, the name and location of the settings may be different.
In the settings window that appears, click the button "Advanced screen options".
Hardware problems
Reason 3: video card failure
If possible, connect your monitor to any other computer. If the vertical stripes have disappeared, but you do not suspect software problems, you can assume that the problem lies with the video card, which may have failed.
Next, you will need to disconnect the video card from your computer, and then insert it into another computer that you are completely confident in its functionality. If the situation with the monitor is similar, you have once again confirmed your guess.
In this case, you will need to try to visually inspect the video card to see if it is covered in dust, and if the contacts are dirty. If the problem is in the contacts, clean them with an eraser and also get rid of all visible dirt. After this, the video card did not work? Then you will not be able to help it in any way: either contact a service center to have it repaired, or replace the video card.
Reason 4: Incorrect monitor connection
Check whether your monitor is connected to the computer correctly: the cable connecting the monitor must be fully plugged in on both sides. We recommend that you additionally use a different outlet for the monitor - it is quite possible that it simply does not have enough power.
If there is any type of damage on the connected cable, the cable must be replaced.
Reason 5: Motherboard failure
A sudden power surge, severe overheating, or a simple manufacturing defect can cause the motherboard to fail.
In this case, of course, if you connect the monitor to another computer, it will work fine. Except for problems with the video card, you should suspect the motherboard - and here everything is already sad, and you won’t be able to help it on your own; you will definitely need to contact a service center (and the sooner the better).
Reason 6: Monitor malfunction
If on other computers the monitor still produces the same reaction with vertical stripes, we can assume that the problem lies in the monitor itself.
Alternatively, try pressing on the top of the monitor with your finger - if the stripes disappear, this may indicate that the cable in the monitor is coming off the matrix body (but this step may not have any effect).
In this case, you will need to take the monitor itself directly to a service center, where they can more accurately diagnose and solve the cause of the problem, or try to disassemble it yourself (of course, if you have at least some experience). If the problem is insufficient contact of the cable with the matrix body, you will need to use something to seal the gasket at the exit point.
As a rule, these are the main reasons for the appearance of vertical stripes on the monitor.
