Last Updated: Jan 26, 2024 by

Are you experiencing lines on your monitor screen? This can be a frustrating and distracting issue, but fortunately, there are steps you can take to troubleshoot and fix the problem. In this article, we’ll discuss the common causes of monitor screen lines and how to fix them.

Troubleshooting Monitor Screen Lines

Before we dive into potential solutions, it’s important to understand the possible causes of monitor screen lines. This will help you narrow down the issue and determine the best course of action.

Loose or Damaged Cables

One of the most common causes of monitor screen lines is loose or damaged cables. If the cables connecting your monitor to your computer are not securely plugged in, it can result in distorted or missing images on your screen. Additionally, if the cables are damaged, it can cause interference and result in lines on your screen.

Outdated Graphics Drivers

Another potential cause of monitor screen lines is outdated graphics drivers. These drivers are responsible for displaying images on your screen, and if they are not up to date, it can cause issues with the display.

Faulty Monitor

In some cases, the issue may be with the monitor itself. If the monitor is old or has been damaged, it may be the source of the lines on your screen.

How to Fix Monitor Screen Lines

Now that we’ve identified some potential causes, let’s discuss how to fix monitor screen lines.

Check and Secure Cables

The first step is to check all the cables connecting your monitor to your computer. Make sure they are securely plugged in and not damaged. If you notice any damage, replace the cables with new ones.

Update Graphics Drivers

If your graphics drivers are outdated, it’s important to update them. This can usually be done through your computer’s device manager or by downloading the latest drivers from the manufacturer’s website. Once updated, restart your computer and check if the lines on your monitor screen have disappeared.

Adjust Screen Resolution

Sometimes, the issue may be with the screen resolution. If the resolution is set too high, it can cause lines on your screen. To adjust the resolution, right-click on your desktop and select “Display Settings”. From there, you can adjust the resolution to a lower setting and see if the lines disappear.

Reset Monitor Settings

If the above steps do not resolve the issue, you can try resetting your monitor settings. This will revert the monitor back to its default settings and may fix any display issues. To reset your monitor, refer to the manufacturer’s instructions or consult the user manual.

Replace Monitor

If none of the above solutions work, it may be time to replace your monitor. If the monitor is old or damaged, it may not be fixable and will need to be replaced. Consider investing in a high-quality monitor to avoid similar issues in the future.

Preventing Monitor Screen Lines

While some causes of monitor screen lines may be out of your control, there are steps you can take to prevent this issue from occurring in the future.

Properly Secure Cables

To prevent loose or damaged cables from causing lines on your monitor screen, make sure to properly secure them. This includes regularly checking the cables and replacing them if they show signs of wear and tear.

Keep Graphics Drivers Up to Date

Make it a habit to regularly check for updates to your graphics drivers. This will ensure that your computer is always using the latest drivers and can help prevent display issues.

Handle Your Monitor with Care

To avoid damaging your monitor, handle it with care. Avoid placing heavy objects on top of it and be gentle when adjusting the screen or moving it.


Dealing with lines on your monitor screen can be frustrating, but with the right troubleshooting steps, you can fix the issue and prevent it from happening in the future. By checking and securing cables, updating graphics drivers, and properly handling your monitor, you can keep your screen free of lines and enjoy a clear and uninterrupted display.
