A vertical line appears on the monitor

The monitor is one of the most important devices for working with a personal computer. It helps you obtain all the necessary information. However, sometimes a situation arises when the monitor breaks down or begins to work incorrectly. For example, stripes of different colors may appear, ripples or the picture may be incomplete. There are few reasons for their appearance. These are either problems with the monitor itself, or incorrect operation of the system unit. What to do if a green thin strip appears? Let's try to figure it out.

ADVICE. Before you start searching for possible problems and ways to solve them, it is advisable to connect the screen to another system unit. This will help narrow down the possible causes.

Why do vertical stripes appear on the screen?

There may be several reasons for this defect to appear. All of them are divided into hardware or software. That is, some are caused by the breakdown of some computer component, while others are caused by the absence or errors in the operation of the software.

The main reasons include:

• "Motherboard." Failure of this component occurs very rarely. Usually the board breaks due to manufacturing defects.As a rule, motherboard failure only in extreme cases leads to streaking on the display. Resistors located on the motherboard may also break. Upon inspection it will be visible that they are black in color.
• Matrix. This device is quite fragile. Its breakdown can be caused by a power surge, excessive air humidity or mechanical impact. Typically, the screen is connected to the network using a surge protector to which other devices are already connected. Sometimes this creates noise that causes multi-colored stripes to appear on the display.
• Graphics adapter. The video card is responsible for generating and transmitting images to the display. The adapter, like any other component of the system unit, is subject to various negative influences and may break. Very often it overheats or becomes clogged. Sometimes during operation the wires come off.
• Plume. The video signal is transmitted to the laptop screen using a cable that is connected to the motherboard. Very often during operation it becomes pinched, causing mechanical damage.
• Missing graphics adapter drivers. Problems with them arise after reinstalling the operating system or an incorrect update.
• Incorrect device settings. This could be due to the display resolution being set incorrectly or incorrect settings being made on the device itself.

Vertical stripe on laptop screen

There are several types of screen defects:

• Placed vertically or horizontally.
• Only half of the picture is displayed.
• There are ripples.
• White or multi-colored.

REFERENCE.When identifying the causes and their subsequent elimination, it is very important to know exactly what defects are present, how the stripes are located and what color they are.

White vertical stripe on the monitor

Are white stripes appearing on your monitor? This defect indicates that problems have arisen in the operation of the display matrix. It is necessary to gently press the surface of the monitor and, if the defect disappears, this part of the screen should be replaced. If they flicker or are barely visible, then you should inspect the cable connecting to the system unit or the power filter.

Red vertical stripe on the monitor

The defect is often periodic, that is, it occurs from time to time and is not present all the time. Very often the reason lies in a defect in the cable contacts. In rare cases, red streaks are caused by combustion of system components. If there are bunches of red stripes in the form of a rectangle on the screen, this means that the cable is dusty or its connectors are damaged.

Black vertical stripe on the monitor

This view can be located in any part of the display, sometimes even in the center of the display. The source of the defect may be a failure of the video adapter or its incorrect operation, matrix or cable. If the reason is in the matrix, then this element needs to be replaced.

Yellow vertical stripe on the monitor

When a defect of this color forms, you first need a few things. First, the screen should be disconnected from the system unit and plugged into a power outlet. The disappearance of the defect indicates that you should check the cooler on the video card, as well as update the graphics adapter drivers. It is also worth inspecting the capacitors located on the adapter. If there is swelling, the faulty part must be replaced.

REFERENCE. If the monitor was manufactured with a manufacturing defect, a pink stripe will appear on the surface of its display.

Vertical stripe on the monitor - how to remove it?

Some problems that cause stripes of different colors to appear on your monitor screen can be resolved by yourself.

• Graphics adapter drivers. If the source is missing or incorrectly installed video card drivers, they must be installed. This is done as follows:

1. First you need to open “Control Panel” and find “System” in the menu.
2. In the list on the left, select “Device Manager”.
3. In the “Video Adapters” tab you need to find the installed video card. There should be a yellow exclamation mark next to it, indicating that the drivers do not work or are not installed.
4. If the drivers are installed incorrectly, you need to remove them and reboot the system unit.
5. Then you need to download the necessary drivers from the official website of the graphics adapter manufacturer.
6. After downloading and installation, you also need to reboot the device again.

• Screen resolution. If the culprit is incorrect settings, then you need to set the recommended resolution. To do this you need:

1. While on the desktop, right-click and select “Display Settings” from the menu that appears.
2. Then find “Advanced settings” or “Screen resolution” and set the value recommended by the system.

REFERENCE. The sequence of actions or names of menu items depend on the version of the operating system.

• Video card. First you need to make sure that the problem is in the graphics adapter; to do this, you need to install it in another system unit.If the stripes persist, then the reason is definitely in the video card. The device must be carefully inspected for dust and dirt. If they are present, you need to clean the card. If this does not help, you need to take the adapter to a workshop or buy a new one.
• "Motherboard." If the board fails, you won’t be able to do anything on your own and will have to contact a service center for help. The following repair options can be carried out:

1. Chip heating. An inexpensive repair method, however, does not guarantee that the problem will not arise again.
2. Reballing. The option is more expensive, but it gives an almost 100% guarantee that the stripes will not appear after some time.
3. Chip replacement. An option with 100% success and a guarantee, but it is rarely used.

• Plume. It is quite difficult to repair it yourself; this requires good soldering skills, knowledge of electronics and all the necessary materials. Therefore, it is worth contacting a repair shop.

If none of the solution options helps, or the monitor or system one is already quite old, then it is more advisable to purchase a new device.
