In this blog post, we’ll outline 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!

Top Reasons of Rainbow 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.

Solutions for Rainbows Screen

  • Connecting External Monitor
  • Uninstalling and Reinstalling
  • Replace or Bend the LCD Cable

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.
