How to Fix Vertical Lines on Monitor? Fixed in 7 ways!
If you have annoying vertical lines on your monitor, it not only affects the viewing experience, but may also signal a hardware or software problem. This article will detail how to troubleshoot and fix the vertical line problem on your monitor to help you restore the normal display.
1. Check Monitor Connection
First, make sure that the connection between the monitor and computer is normal:
Make sure the video cables (such as HDMI, DisplayPort, DVI or VGA) are firmly connected to the corresponding ports of the monitor and computer. Loose or damaged cables may cause display problems. Try re-plugging the video cable to ensure a tight connection. If you have a spare video cable, try replacing it to troubleshoot cable problems.
Make sure the video port is not damaged or dirty. If the port is dirty, gently clean it with compressed air or a clean, soft cloth.
2. Updating Graphics Card Drivers
Graphics card driver problem is one of the common causes of abnormal display on the monitor. Driver Sentry is recommended for automatic driver detection and updates, saving time and avoiding errors during installation.
Click the download button to get the latest version of Driver Sentry. After installation, open the software and click "Scan".
After the scan, identify the display driver in the results list and click "Upgrade".
Restart your computer after updating the drivers to ensure the changes take effect.
3. Adjust the Monitor Settings
Certain display settings may cause problems with vertical lines on your monitor:
Enter the display settings (right-click on the desktop and select "Display Settings") to make sure the resolution and refresh rate settings match the optimal settings of your monitor. Try adjusting the resolution and refresh rate to see if the vertical lines are resolved.
Some monitors come with the option to restore default settings in the menu, try resetting the monitor settings to see if the problem can be solved.
4. Check the Graphics Card Hardware
Faulty graphics card hardware may also cause vertical lines on the monitor:
Disconnect the power, open the case and make sure the graphics card is properly inserted into the PCIe slot on the motherboard. If the graphics card is loose or not fully inserted, it may cause display problems. Reinsert the graphics card tightly and make sure the connection is secure.
If you have a spare graphics card, try replacing the card to see if that solves the problem. If the problem disappears after replacing the graphics card, the original graphics card may have a hardware failure.
5. Check Monitor Hardware
Hardware failure of the monitor itself may also cause vertical line problems:
Connect the monitor to other computers or devices to see if the same problem occurs. If the display is normal on other devices, the problem may be on the original computer.
If there is also a vertical line problem on other devices, the monitor itself may be faulty. It is recommended to contact the after-sales service or manufacturer of the monitor for overhaul or replacement.
6. Use the Built-in Diagnostic Tool
Some monitors come with built-in diagnostic tools that can help detect and fix display problems:
Check the monitor user's manual to find out how to access and run the monitor's built-in diagnostic tool. Follow the prompts to diagnose and see if you can find and fix the problem.
7. Check Operating System Settings
Problems with operating system settings may also cause the monitor to display abnormally:
Go to Display Settings and check that the monitors are correctly recognized and arranged. If you are using multiple monitors, make sure the primary monitor is set correctly.
Ensure that the operating system has the latest updates installed. Press "Win + I" to enter the "Settings" page, select "Update and Security", and click "Check for Updates". The system will automatically download and install the latest updates.
The above is the way to fix the vertical lines on your monitor, hope it will help you.
