Laptop screen weird colors and lines – 6 Proven Solutions!

After using your laptop for a while, you may sometimes begin to notice distorted colors and strange lines on the screen. It can also happen to new laptops. Today, we explain why these vexing screen issues arise and what you can do about them. Let’s see some good fixes for these laptop screen issues.

What are the reasons for these colors and lines?

You must first identify the issues before attempting to resolve them. You should determine which component of your machine is the source of the issue. Hardware or software problems may both be the problem. In this case, the two explanations would be:

  • The monitor/screen could be causing this complication. It’s usually easy to spot by lightly pressing on the panel and noting the changes.
  • Another issue could be with the driver for your graphics card or any other driver. You must update and correct them.

This article is going to help fix any problem you may have. Let’s see what you may do to correct the distorted lines or strange colors on your laptop screen. If you don’t know a thing about this, we recommend taking your laptop to a professional.

How To Fix The Hardware Problem?

If your laptop screen has distorted lines or colors, you should take it to a local laptop repair and maintenance business. If your product is covered by a warranty, you should take it to one of the manufacturer’s approved repair shops. It will help you save money. 

However, if you have knowledge and want to fix the problem yourself, follow our instructions. The techniques for repairing your laptop screen on your own are outlined here.

1. Restarting Your Laptop

The first thing to do is restart your laptop to look for distorted lines or strange colors on your screen. Turn off your computer and wait for five minutes.

Unfinished programs, RAM overload, spyware, viruses, and other factors might cause strange colors and lines to appear on your laptop screen. In this scenario, a simple restart might solve the problem! If that doesn’t work, there are a few additional options.

2. Fixing The Problem Using An External Monitor

If a restart hasn’t resolved your screen issue, you’ll need to determine whether or not your laptop’s screen is malfunctioning. As a result, you can utilize a monitor to check the screen on your laptop. However, it is possible not to access an external monitor at home. So, how do you go about it?

It would be best if you don’t buy a new laptop monitor only to examine the screen on your current one. Test your laptop with the assistance of a repairman. Here’s a guide i wrote on how often you should buy a new laptop, you can give it a read.

You can quickly test your laptop if you have access to an external monitor. To test, you’ll need a VGA/DVI cable, S-Video cable, or HDMI cable. If your monitor isn’t capable of doing so, you’ll have to connect it manually.

If the display on both screens is strange, it’s most likely due to outdated graphics drivers, a broken LCD connection, or a faulty cable.

3. By Updating Graphic Card Drivers

It is a straightforward procedure. Look for the newest driver for your graphics card if you know the model (NVIDIA, AMD, Intel). Update your laptop’s video card drivers to the most recent version.

You can utilize an app if you don’t know your graphics card model or want a more direct experience. DriverFix is an app that we recommend.

It is very inexpensive. For roughly $20 per year, you can get a license for a single PC. The software will detect broken or obsolete drivers automatically. You can easily update them. Otherwise, do it by replacing the graphic card.

4. By Checking The LCD Cable Connection With The Motherboard

If your laptop screen is in good working order, but you still notice vertical lines, it could be due to a faulty connection between the LCD and the motherboard. Let’s have a look at how it works. Signals are sent from your laptop’s motherboard via a connection. The connection must be stable.

It is dangerous to continue using a broken cable or worn out. Vertical lines will be warped as a result of this. It’s something you should change.

Check to see if the cable is correctly connected. If it’s not connected correctly, tighten it up. Under the keyboard lies the connection between the laptop’s LCD panel and the motherboard. It would be best if you first dislodged the keyboard. Look up how-to videos and guides online.

5. Replace the LCD cable

A faulty LCD cable will hamper your viewing experience. If the cable is worn out, you should replace it immediately. It is inexpensive. If the cable looks like it is in good condition, you might want to try wiggling it. If the computer screen flickers or shows distortion while wiggling, you should also update the cable.

6. Check the display screen.

If none of the above approaches worked for you, you should look at the screen itself. Before you replace the PC screen, make sure it needs replacement. 

Gently press the topmost portion of your laptop’s screen. If you notice any distortions or bright spots, it’s time to replace your display. You can trust us on this. It’ll only become worse if you don’t get it changed soon.


It’s inconvenient to have a flickering or distorted laptop display. You can take it to an expert if you’re unsure or don’t want to take any chances. You don’t have to buy a laptop or repair the display every time you see a flickering screen. Next time you get strange colors and lines on your laptop, don’t crush it!
