aIn the course of using your PC or laptop, you may have encountered vertical lines running from the top to the bottom of your computer screen, either blue, white or multi-colored.

This may create a lot of anxiety especially when you fear that your machine may be crashing.

Well, you’d be relieved to know that the vertical lines can be a thing of the past, and no, your laptop isn’t crashing anytime soon – at least not because of the vertical lines.

Vertical lines seen on a computer screen may be a result of hardware failure, which requires a hard reset (or forced reset), or an issue with your video (graphics) card.

In most cases, these lines are caused by damage to the screen.

If the lines are different colors, or width changes when you add pressure from the panel, then the issue is probably your computer’s LCD screen, which would require a replacement.

Without further ado, let’s cut to the chase and fix the vertical lines problem already.

How to fix vertical lines on your PC monitor?

1. Check your Screen Resolution display settings

This involves adjusting your computer screen’s display settings in order to get the best display on your monitor.

Here’s how to do it:

  • Right click Start
  • Select Control Panel
  • Go to Appearance and Personalization

  • You’ll see the resolution marked Recommended. This is the one suitable for your laptop screen’s native resolution – the highest your monitor can support.

You can set brightness and contrast from monitor controls. For a laptop screen, these are adjusted within Windows under Power Options.

2. Update your video card or graphics driver

Here’s how to update drivers on Windows:

  • Right click Start button
  • Select Device Manager
  • Click on Universal Serial Bus Controllers to expand the list

  • See whether there are any devices with either a yellow exclamation mark, question mark, down-arrow mark, or an error notification or code.
  • If the driver has a yellow exclamation mark on it, double click on it then open Properties
  • Under Drivers tab, choose Update Driver

Windows will find the appropriate driver for your video card or graphics driver.

Note: You may need to know the name of your graphics or video card, for instance, if it is NVIDIA, AMD or Intel, because then you’d have to download directly from the website of either of these.

Update drivers automatically

In order to prevent PC damage by installing the wrong driver versions,  we suggest to do it automatically by using Tweakbit’s Driver Updater tool.

This tool is approved by Microsoft and Norton Antivirus and will update your correct drivers automatically. After several tests, our team concluded that this is the best automatized solution. Here’s a quick guide on how to do it.

    1. Download and install TweakBit Driver Updater
    2. driver updater starting windowOnce installed, the program will start scanning your PC for outdated drivers automatically.

To update one driver at a time, click the ‘Update driver’ link next to the driver name. Or simply click the ‘Update all’ button at the bottom to automatically install all recommended updates.

5. Check whether the vertical lines appear in the BIOS

Here’s how to do this:

  • Shut down your computer, but keep the power cable connected
  • Turn it on again
  • Press F10 repeatedly

If you get to the BIOS settings and the lines are still displaying, it may be a hardware failure. In this case, perform a hard or forced reset, then a BIOS update.

If you don’t get any vertical lines displayed in the BIOS, it is a software related issue such as outdated drivers, in which case you need to update the display drivers.

How to update display drivers

In order to do this, you need to start your computer on Safe Mode, then uninstall your current display adapter, and finally check for driver updates.

Safe mode starts up your computer with limited files and drivers but Windows will still run. To know whether you’re on Safe mode, you’ll see the words at the corners of your screen.

If the screen flickering issue persists, check whether it occurs while your computer is in Safe mode.

There are two versions:

  • Safe mode
  • Safe mode with Networking

The two are similar, though the latter includes network drivers and other services necessary to access the web and other computers in the same network.

Follow these steps to start your computer in Safe Mode:

  • Click on Start button
  • Select Settings – the Settings box will open up
  • Click Update & Security
  • Select Recovery from the left pane
  • Go to Advanced startup
  • Click Restart now

  • Select Troubleshoot from the choose an option screen, then click Advanced options
  • Go to Startup Settings and click Restart
  • Once your computer restarts, a list of options will come up.
  • Choose 4 or F4 to start your computer in Safe Mode

A quicker way to get into Safe Mode is to restart your computer then do the following:

  • From the Choose an option screen, select Troubleshoot>Advanced options>Startup Settings>Restart
  • Once your computer restarts, a list of options will come up.
  • Choose 4 or F4 to start your computer in Safe Mode

If the screen flickering problem isn’t there while in Safe mode, then your default settings and basic drivers are not contributing to the issue.

Once you start your computer in safe mode, do the following:

  • Right click Start
  • Select Device Manager
  • Expand Display adapters
  • Right click the listed adapter
  • Select Uninstall device
  • Choose the Delete the driver software for this device box
  • Select Uninstall
  • Reboot your computer

Once your computer reboots, click Start, choose Settings, then select Update & Security > Windows Update > Check for updates.

If you have many display adapters, you need to disable the added display adapter by doing the following:

  • Right click the added adapter from Device Manager
  • Select Disable
  • Click Yes
  • Turn off your computer
  • Disconnect installation or recovery media (if using it)
  • Turn on your computer

If this doesn’t fix the vertical lines on the computer screen, do the following:

  • Restart in Safe Mode
  • Re-enable the added display adapter
  • Disable the other adapter

Once you’re through and the screen flickering is sorted, exit safe mode so you can get your computer back to normal mode.

How to exit Safe Mode:

  • Right click Start button
  • Select Run
  • Type msconfig
  • A pop up will open
  • Go to the Boot tab
  • Deselect or uncheck Safe Boot option box
  • Restart your computer

6. Perform a Clean Boot

If Safe Mode didn’t work, try a clean boot.

Performing a clean boot for your computer reduces conflicts related to software that can bring up the root causes of the Startup Repair incompatibility with your operating system. These conflicts can be caused by applications and services that start up and run in the background whenever you start Windows normally.

In order to successfully perform a clean boot on Windows 10, you have to be logged on as the administrator, then follow these steps:

  • Go to the search box
  • Type msconfig
  • Select System Configuration
  • Find Services tab
  • Select Hide all Microsoft services box

fix vertical lines on screen

  • Click Disable all
  • Go to Startup tab
  • Click Open Task Manager
  • Close Task manager then click Ok
  • Reboot your computer

You will have a clean boot environment after all these steps are carefully followed, after which you can try booting your computer again.
