By the end of this blog, you will be able to resolve the vertical lines issue on your PC as we discuss multiple ways to fix the same. Without further ado, let’s begin!

Why Are There Verticals on Computer Screens?

There are multiple reasons why your PC may be experiencing display-related issues. These errors include –

The connection between your computer screen and the CPU is not proper.
You are using a faulty screen or monitor
There’s an error with the graphics card you are using.
The application you are using is giving it false information.

In all cases, you may experience vertical lines on your monitor screen. If your monitor is under warranty and you doubt there’s an internal error in the hardware, feel free to contact the service center.

However, if your service advisor says there’s nothing wrong with the panel, move on to the next section to find the fixes you can apply.

Effective Ways to Fix Vertical Lines on Laptop Screens

Before jumping to the major fixes, ensure you have performed the basic checks to see if the issue is resolved. The basic fixes include –

Restart Your PC as soon as the vertical lines appear. Notice if the startup screen has vertical lines or not.
Detach and reattach the connection cables of your display device to check if that resolves the issue.
Try using a different cable to ensure that the cable is not causing the issue.
Get rid of dirt or dust from your monitor to allow it to function properly.

Once you finish the basic checks, it’s time to move to the advanced methods.

Method 1 – Update Graphics Drivers on your PC

The first thing that comes to mind whenever there’s an issue with the display is your PC’s GPU or graphics. In case you are using an older device, there are chances that the graphics driver is causing the issue. To resolve this problem, you can update the graphics driver on your PC.

If you know how to update drivers on your Windows PC, you already know how typical it is to go through the Device Manager and fetch updates manually. Hence, we recommend you use Advanced Driver Updater. A tool that knows how to update drivers better than any other.

All you have to do is –

Step 1 – Download Advanced Driver Updater on your PC using the button below

Step 2 – Install the tool on your PC and run it.
Step 3 – Click the Start Scan Now button on the home screen to begin scanning.

Step 4 – This scan will go through all the installed drivers to find the outdated ones.
Step 5 – After the scan, you will have a list of outdated drivers.

Step 6 – Click on Update All to update these drivers.

The application allows you to find, fetch and install the updates for all your PC drivers in just a few clicks, including your graphics drivers.

Method 2 – Adjust the Screen Resolution Settings

Sometimes the lines appear due to issues with the screen resolution settings on Windows. Try playing around with the settings to check if the lines are consistent in all the modes, or is it just the current configuration causing the issue,

Here’s how you do it –

Step 1 – Go to your Desktop and right-click to find Display Settings in the quick-access menu.

Step 2 – You may find Display Resolution settings when you click the drop-down menu in the opened settings.

Step 3 – Click on the drop-down menu and try the configurations individually to see where the lines disappear.
Step 4 – Save the configuration where you no longer see the vertical lines on your screen.

Method 3 – Perform a Clean Boot

If the vertical lines flickering issue on the screen are caused due to a running application or a program, performing a clean boot is the best way to handle them. It will clean all the running services and give your PC a fresh start.

Here’s how you do it –

Step 1 – Use the Run search box (Win+R) and use the command msconfig in the search box.

Step 2 – In the top bar, find the services tab and click on it.
Step 3 – First mark the box that says Hide all Microsoft services and then click on Disable all option on the right side.

Step 4 – Once you are done with that, change the tab to startup where you may find an option to open the task manager.

Step 5 – Now, similarly as you did in the previous method, disable the startup application from Chrome or any other app you believe is creating an issue.
Step 6 – Once you are done with all the steps, simply save the changes and reboot the PC.

This way, you can remove the vertical lines that appear on your PC. Remember that these advanced fixes will only work if you have already gone through the basics. Hence always ensure you have tried everything before making any changes to the system settings.
