Solving Weird Laptop Screen Problem

To fix the screen of your laptop, first, you have to identify what is causing this difficulty. Be sure to find out what kind of problem it is you’re dealing with.

Troubleshooting the Problems

If you’re having trouble with your laptop’s image quality, you might be able to fix it yourself by getting help from someone who knows what they’re doing at a local laptop repair shop.

If that isn’t an option for you though or if you’d like to give it a try on your own, here’s how to diagnose and repair the problem yourself.

Restart the Laptop

Fixing distorted lines can be quite a challenge. However, there is a simple way to get the issue solved. First of all, turn off your laptop and wait for at least 5 minutes before turning it on again.

In this way, the screen will be able to cool down and you can start enjoying a distortion-free display. There might be some programs out there that malfunction when an external monitor is being used which could cause issues with your laptop’s display.

Therefore it is most recommended that one should restart their computer every once in a while in order to fix such problems.

Check the Laptop Screen

To ensure that your laptop’s display is good as new, try applying gentle pressure on the upper panel of the screen. It will tell you if there are any problems with it.

If you see colorful lines or dots under the pressure, it means that there is a problem with your display and you should replace it immediately.

If the display still looks and works fine even after applying light pressure, then you don’t really need to worry about replacing your laptop’s screen – although we still wouldn’t blame you for wanting to upgrade to a higher resolution model if available.

Updating the Graphics Card Drivers

Another option that you can try is updating the drivers of your laptop that deal with video. At times, we may have old versions of operating systems and software and this makes it difficult to access updates properly.

Go ahead and check out these updated drivers and reboot your computer as well for good measure if the issue continues to persist.

LCD Cable should be Replaced

Test the cable by plugging your laptop into another power source (like an outlet) and see if the issue persists. If it does, there’s a problem with the cord.

You can then test the connection per USB port with another device to make sure that the USB port isn’t loose. It’s also a good idea to try wiggling around cables inside while the machine is running to see if they cause any visual distortions on the screen.

If you have any of these issues, it’s time to get a new cable for about $10 from Amazon or any local electronics store.

Checking Cable Connection of LCD with Motherboard

Have you recently checked to see if your laptop’s monitor is working properly? Is it showing any lines or distortion, or are the colors off/unnatural in some way?

Well, if you have an issue with your screen but find no problems when checking other devices like your computer monitor, there could be something wrong with the connection between the display and the motherboard.

There are two parts of your laptop which you should be familiar with – the screen and the motherboard.

The screen is the part that displays what you’re working on while using your computer while the motherboard takes care of keeping everything in your laptop running smoothly.

Your motherboard will never work without a connection to the laptop’s LCD screen so it’s important to know how they interact together.

A cable called a display port connects the two main parts of your laptop together – making sure you have access to an image both vibrant and powerful anytime you switch on or plug in your computer.

Fix the Problem by using an External Monitor

Flickering or distorted line troubleshooting could be due to a few different things, but it’s hard to know for sure without doing some research and examining the problem in question.

A laptop and computer repair firm will be able to get you the help you need if your laptop is still under warranty or otherwise has been taken care of properly.

If you have an external monitor available you should be able to connect your laptop by using a VGA cable, DVI cable, S-Video cable, or HDMI cable in order to find out what’s going on.

Connective technology plays an important role in everyday life. The most common type of connection is the VGA connection for monitors, which allows you to extend the display on your laptop so that it can be seen on another monitor.

Some monitors can automatically detect what kind of connection they are given and redirect the image onto both screens without user intervention, while others require you to manually select between internal or external modes using function keys provided by the computer’s manufacturer.

Sometimes it may be necessary to display your laptop screen on your monitor manually. For this, take advantage of the function keys which can be used to activate the video switching between external and internal modes.

Within the specifications for laptops from Hp, Toshiba, Dell, and Lenovo as well as a number of other brands that use similar F-keys where F4 / Fn+F4 refers to seeing an image on a connected monitor using a wireless link, F5 / Fn+F5 is used for a wired connection where manual configuration is required via a passkey or a special code.

To regain access to a display attached via an external adapter you need the combination of Fn+4 followed by pressing either 4 or 5, depending on what brand you have.

FAQs Related to Laptop Screen Weird Colors and Lines

Why is my laptop screen showing colored lines?

View your screen for any issues when turning on your computer or opening Windows – the most common signs of video card issues are either static images on the screen or lines flickering in front of you.
Depending on where these images are appearing, you’ll need to check the video card, the connection cable (such as an HDMI or VGA cable), or the monitor itself to try and determine what might be causing this issue.
With Windows, however, one issue that can cause problems with your screen is related to refresh rates — which you can see in settings in Windows if you’re familiar with them.

Is it worth fixing a laptop screen?

Repairing a laptop by replacing its hardware will always come up more costly than you think. If you happened to purchase a high-end model that wasn’t cheap but you don’t have the money to repair it, then it’s not worth it because of how expensive it is to repair your laptop after all this time.
For example, if your laptop costs $1000 brand new and its screen cracks in year two of regular use, you shouldn’t pay more than $100 for its repair part.
Anything the shop charges over that price like if they needlessly replace “all-new hardware” or something outrageous like that is probably done out of greediness and is an apt opportunity for you to seek out another shop with better integrity.
