Fix horizontal lines on your laptop screen

It doesn’t matter if you call it a glitch, or a technical problem. The horizontal lines that appear on your laptop screen are annoying and should be fixed as soon as possible.

Let’s look at the main reasons for these lines appearing on your laptop and learn how to remove them.

Horizontal lines on laptop screens: What causes them?

Understanding why horizontal lines appear on your laptop screen can be extremely helpful in resolving the problem.

Hardware Issues

Overheating

Overheating is not a common problem, but it can result in horizontal lines on your computer. If you’ve been working on your laptop for a few days and it hasn’t been shut down, the chances are high that you will have display issues.

Overheating can cause a variety of problems, including horizontal lines.

LCD Panel Damage

If your LCD panel has been damaged or is defective, you will see horizontal lines and other glitches. If you find that your LCD panel is damaged or defective, it will be necessary to replace it.

Graphic Card

The graphics card improves the appearance of your laptop. If it is damaged or faulty in any way, you may experience visual glitches.

Why you should –

• The GPU (Graphics Processing Unit), if damaged or overheated, can cause horizontal lines to appear on your laptop’s screen.
• Even if your graphics card is physically damaged, visual glitches may appear.
• Horizontal lines on your screen can also be caused by loose internal cables.

Connecting your laptop to an outside monitor will allow you to check if your graphic card is causing the horizontal lines. If horizontal lines are visible on an external monitor, it means that your graphic card needs to be checked.

Software Issues

Set Screen Resolution

You can get horizontal lines if you change the resolution of your laptop without thinking.

Any display setting that is not in line with the screen resolution and size can cause image stretching, resulting in visual glitches. Always choose the settings compatible with your laptop’s screen.

Drivers not up-to-date

You will soon experience display problems if you do not update your graphics drivers. Some software may not work well with an old graphic driver. Therefore, software companies release drivers according to current market conditions.

You should update your system before it gets out of control.

How to Fix Horizontal Lines on Laptop Screen?

The phrase “the problem is the solution” may have been heard before. The same is true for horizontal lines. There are some easy things you can do to fix the problem.

Check for Physical Damage

You should always check your screen’s condition when you see a horizontal line. Your laptop may have been ‘patted’ while you carried it.

Even a small amount of force can damage the display screen. It is important to keep your laptop safe.

If you do find damage to your screen, it is worth replacing the entire thing with a brand new one. This will solve the problem of horizontal lines.

Test the issue using an external monitor

You can use an external monitor to determine if the problem is software or hardware.

Connect an external monitor to your laptop, and then turn on the operating systems. Examine carefully whether or not the display problem is present on the external monitor. If you don’t see the problem, it means that your device has some kind of physical damage. If you still see the horizontal lines on your external monitor, it means that there is an internal software problem.

Update your Graphic Driver

You may have already encountered several laptop problems if you are lazy and skip updates whenever they appear on your screen. Updates are good for your laptop and can fix any faults that may have existed. It’s no wonder that companies release them periodically.

If you see horizontal lines on the screen of your laptop, try updating it and check if that solves the problem.

How to change the display settings on your laptop

The wrong display settings may cause image compression or stretching, which will affect the visuals on your laptop.

Just follow the steps below – Settings > System Display

Choose the recommended settings for the display to achieve the best output. You can also adjust the refresh rate to see if it makes things smoother. Even that can sometimes help to make magic happen.

Use Display Quality Troubleshooter

This tool is built into Windows and is used to diagnose any display problems you may encounter on your laptop.

Display quality troubleshooter’s primary function is to identify any visual faults and determine whether they are due to a hardware or software glitch.

Follow the steps below to find the Windows display quality troubleshooter.

Press Windows Key + I to open the Windows Settings App. Select System > Troubleshoot, Other Troubleshooters, Display Troubleshooter and then click Run.

You can now run the troubleshooter, wait for it to detect the problem and its cause and then follow the steps that are provided.

If the problem is hardware-based (damage, etc. ), then you will need to contact a technician. For any of these queries, contact Laptop Repair Dubai as we provide the best laptop repairs in Dubai.

You can perform a clean boot to find the core of the problem

A clean boot is a way to help your system use the minimum amount of programs and drivers. If you clean boot your computer and no horizontal lines appear on the screen, it means that a third-party program is responsible for the problem.

Use the following method to clean your boot:

• Selective startup > Go to System Configuration > General tab > Uncheck the Load Startup Item box
• Then, click “Disable all” and then “Hide All Microsoft Services”.
• Now – Click on the Startup tab > Open Task manager > Disable all startup items in the Task Manager window > Click OK and Save Changes.

If the lines are not still visible, restart your laptop. And not, then it is likely that an application is the cause of the problem. If the problem persists, it may be due to a hardware problem such as a damaged graphic card or another issue mentioned in this article’s hardware section.

You should also remember that a “clean boot” will close down all startup items and services. Therefore, you’ll have to enable them again in the same settings.

Check for Malware

It is not something that happens very often, so we kept it at the end. You may have malware affecting the display drivers on your laptop, causing various visual problems including horizontal lines.

You can scan your computer for malware using any antivirus software and then see if the problem is resolved later.

Some of the most popular antiviruses are –

• Bitdefender Antivirus ‘Plus’
• Norton 360
• Malwarebytes Premium Security
• McAfee Antivirus Plus
• Avast ‘One’

You can choose any of these antiviruses to detect and remove any malicious malware activity on your system.
