How to Fix Rainbow Screen on Laptop or Computer 2022

Have you ever been using your laptop and suddenly the screen turned rainbow-colored? This can be really frustrating, especially if you’re in the middle of working on something important.

But don’t worry, you’re not the only one. This has happened to me and to a lot of people. In this blog post, I’m going to tell you how I fixed the Rainbow screen on a laptop.

I have outlined some possible solutions for how to fix rainbow screen on laptop so that you can get back to work as soon as possible. Let’s get started.

How to Fix Rainbow Screen on Laptop And Top Reasons For Rainbow Static Screen.

Top Reasons For Rainbow Static Screen.


One of the most common reasons for the rainbow screen is due to heating issues. When your laptop gets too hot, it can cause the screen to display a rainbow of colors.

Dusty vents or an overheating CPU usually cause this. To fix this issue, you’ll need to clean out your laptop’s vents and make sure that the CPU is properly cooled.

Buggy or unreliable display software.

Another possible reason for the rainbow screen is due to an issue with the display software. A corrupted graphics driver or a problem with the display settings can cause this. To fix this, you’ll need to update your graphics driver and make sure that the display settings are correct.

Cables that don’t work

Yet another reason for the rainbow screen is a problem with the cables connecting the display to the graphics card.

If these cables are loose or damaged, it can cause the screen to display a rainbow of colors. To fix this issue, you’ll need to check the cables and make sure that they’re properly connected.

Modifications to the display settings

If you’re seeing a rainbow screen, the first thing you should do is try restarting your computer. In many cases, this will be all that’s needed to fix the problem.

If that doesn’t work, try updating your drivers. You can usually do this by going to your manufacturer’s website and downloading the latest drivers. If that doesn’t work, you might need to get a new graphics card or display adapter.

Tampered Display Settings.

Pets and toddlers love to play with laptop computers. They are attracted to the colorful display and entertaining activities they can see on the screen.

Unfortunately, these same displays can be the source of static rainbow laptop screens. When pets or toddlers tamper with the display settings, they may inadvertently change the refresh rate or resolution.

This can cause images to appear distorted or reason to flicker on the screen. In addition, specific colors may become oversaturated, resulting in a static rainbow effect.

If you are experiencing this problem, you should check your display settings to ensure they are still set to your preferred levels.

Damaged Hardware and Display Drivers

Damaged Hardware and Display Drivers

A horizontal line on your laptop screen can be very frustrating. There are a few possible causes for this problem, but the most likely reasons are damaged hardware or a corrupt display driver.

If you’ve recently dropped your laptop or otherwise subject it to physical trauma, it’s possible that the screen was damaged in the process. In this case, you’ll need to have the screen replaced by a professional.

Alternatively, the problem may be caused by a corrupted display driver. This can often be fixed by reinstalling the driver or updating to the latest version. 

Solutions for how to fix horizontal lines on laptop screen

  • Restarting Laptop
  • Connecting External Monitor
  • Uninstalling and Reinstalling
  • Replace or Bend the LCD Cable
  • Settings in Windows

Restarting Laptop

Restarting Laptop

Please turn off the monitor for 15 seconds, and then turn it back on. There might be some minor problems with your computer’s connection. Your computer can start working again if you restart it.

If the problem disappears but reappears soon, especially color-related, consider turning off the screen for 30 minutes before turning it back on. If it doesn’t help, your monitor may be overheated.

Connecting External Monitor

Connecting External Monitor

Turn off the laptop (not sleep or hibernate, but off). Connect the laptop to an external display. Then switch on the laptop and the external display.

You may need to use an “external monitor” button. For the external monitor to operate, it might be the “f4” button or a button with two displays on it. If you can see fine on the external monitor, the problem is with your connected display or the ribbon connection that links it.

If you can’t see anything on the external display, or if the problem happens on the external monitor, the problem is most likely with the graphics card/GPU, which may need the replacement of the motherboard.

Uninstalling and Reinstalling

Well, suppose you are facing the problem of display malfunction after a bad or beta display update.

In that case, it is best to uninstall by ultimately getting rid of the display driver through either “device manager” utility for installing third-party software like “IOBIT,” which will eventually get rid of your problem so you can cleanly install an older and much more stable version of the display driver.

Moreover, if that is too complex for you, you can boot up in safe mode where a third party or additional software is disabled and check if your problems persist.

Replace or Bend the LCD Cable

You may try to bend the cable while the laptop is operating to see if it creates any screen flickering or distortion difficulties. And if it does provide strange results, therefore, it’s time to replace it.

Settings in Windows

You may go to your monitor display in Windows settings and look for any unexpected settings that have been enabled that you would not have switched on otherwise.

If you can’t seem to locate any, you may click on factory reset settings or a restore point option in Windows settings to reset your settings, but be aware that you may lose other settings that need changing again, so use this option as a last choice.

Contact a maintenance specialist

Vertical lines on laptop screen can be very frustrating, as they can make it difficult to read text or see images clearly. If you are experiencing this problem, the best course of action is to contact a maintenance specialist.

These experts will be able to diagnose the problem and determine whether it can be repaired. In many cases, the lines can be fixed by simply replacing a faulty component.

However, if the damage is more severe, it may be necessary to replace the entire screen. Either way, a qualified specialist will be able to help you get your laptop back up and running in no time.

Driver Updates for Graphics Cards

One common issue that can cause a static laptop screen is outdated display drivers. Display drivers are responsible for communicating between the computer and the display, so it’s important to keep them up to date in order to avoid any display issues.

Many times, display driver updates will be included in regular system updates, so it’s important to keep your system up to date as well.

However, if you’re still seeing a static display after updating your system, make sure your graphics card drivers are updated as well. Usually, you can download drivers from the manufacturer’s website for your graphics card.

If the problem persists after installing the new drivers, restart your computer and check whether the new drivers have solved it.
