If you see vertical or horizontal lines on your laptop or desktop screen, it’s not a good sign. This clearly means that there is a serious problem with your screen. If you see blue, red, green or black vertical lines on your laptop screen, then this article is for you. In this guide you will learn how to fix black vertical lines on laptop screen.
Why is There a Line on My Laptop Screen?
These vertical or horizontal lines are the result of different problems. Some causes of lines on a laptop screen include overheating, physical damage to the monitor or its connection cable, a conflict between the screen and the selected resolution, incorrect refresh rate settings, or outdated device drivers and operating systems.
They can also be caused by a faulty HDMI or DisplayPort monitor driver or a system error that causes the laptop monitor to malfunction.
How to Fix Vertical Black Lines on Laptop Screen?
In this article, we’ll look at possible solutions to help you fix vertical lines on your monitor.
Solution 1: Reconnect the Video Cable
Loose or damaged connections can cause graphics distortion such as vertical lines. Reconnecting the video cable may improve the connection between the monitor and the video card and solve the problem. If reconnecting the cable does not solve the problem, replace the cable with another HDMI or DisplayPort cable.
Solution 2: Replace the Cable (HDMI, Ribbon, Display Port)
The ribbon cable system is responsible for transferring data from the GPU to the monitor. If there is a problem with this cable, vertical lines may appear on the screen. A damaged ribbon cable may have an open or short circuit, preventing the ribbon cable from transmitting information to the monitor.
Replacing the faulty ribbon cable with a new, undamaged ribbon cable will restore normal communication between the motherboard and the monitor and the vertical lines on the laptop screen will likely disappear.
Solution 3: Use Display Quality Troubleshooter
Screen Quality Troubleshooter automatically detects problems related to video drivers, graphics cards or video settings. It has been designed to work with different operating systems, ensuring compatibility and accuracy in diagnosing problems.
To use Screen Quality Troubleshooter on your device, please follow these steps
Type “control” in the search menu. Then click Control in the list of results.
Next, set the Screen with the option to the Large icon in the right-hand corner of the screen.
Next, click on Troubleshooting.
In the left-hand pane, click Show All.
Then click Show Quality.
Enter your administrator password or grant the appropriate permissions when prompted.
Solution 4: Fix System File Corruption
If you are having problems with your Windows system files, System File Checker (SFC) and Deployment Image Service and Management (DISM) can help you repair corrupted system files.
First, try the SFC command on your computer, and if it does not work, use the DISM command to repair the corrupted system files.
Press the Windows key + R to open the Run dialog box.
In the Run dialog box, type cmd and press Enter.
In the command window that opens, type sfc/scannow and press Enter.
Be patient until the scanning is finished. This process takes about 15 minutes.
When the SFC scan is finished, check if the vertical lines disappear from the screen. If an error still occurs, run DISM from the command line.
Run the command line, type dism /online /cleanup-image /restorehealth and press Enter.
Wait for the check procedure to finish. This process takes about 30 minutes.
After restarting the computer, check that the problem has been solved.
Solution 5: Update your Graphics Driver
An outdated or incompatible driver can cause inconsistencies or errors in the display of images and graphics and cause vertical lag. In addition, updating your graphics driver will improve system performance and resolve compatibility issues such as vertical black lines on your laptop screen.
Follow the instructions below to update your graphics driver.
Press Windows + X and open the Device Manager menu.
Double-click on Drivers, check if any of your computer’s drivers need updating, and select them.
Then go to the manufacturer’s website and download the driver that fits your computer’s configuration.
Intel
AMD
NVIDIA
.exe files will be downloaded to your computer. To install the drivers, double-click on the files to run them.
Solution 6: Adjust the Screen Resolution
You can also adjust the resolution of your computer screen to check if the laptop’s display settings are causing problems.
Follow these instructions to adjust the screen resolution.
Open the desktop by pressing the Windows + D keys. Now right-click in the empty area and select Display Settings.
On the right tab, open the Screen Resolution section, drag down the drop-down menu and select the recommended resolution as shown in the image below.
Now check if the vertical lines on your computer have been corrected.
Solution 7: Gently Wipe the Screen with Cotton Balls
Another cause is the accumulation of dust and dirt on the screen and frame, which can be cleaned with cotton swabs. Swabs can also absorb moisture clinging to the frame, which can cause corrosion or electrical interference on these lines.
Finally, cotton swabs can be used to correct misaligned electrical connections on the frame, which can also cause vertical black lines. As you can see, simple measures can often solve display problems.
