Windows 10: Screen suddenly splitting

I have my HP laptop connected on a Dell monitor. It usually splits horizontally showing two complete screens one above the other. This happens on its own without any input or so. Closing the laptop returns it back to normal.

Split screen

When I go to a split screen view in Windows 10, one of the screens will stop working and/or not respond. For example, if I have a video playing and split screens, the video will stop running but the sound will continue. Another example is that I will
try to use a newly opened screen in split view and the page will not respond. Any suggestions or help?

Hi Gigi Louise,

We appreciate you for being a part of Windows 10.

Before proceeding, we need more information to help you better.

• 
  Have you made any changes to the computer prior to the issue?
  
• 
  When the screen starts splitting exactly? Is it when you try to access any app/it randomly splits?
  

You may try to disable third party applications/software (if any installed) in Windows 10 before performing below methods to check if it is the root cause to the issue.

Disclaimer: Using Third Party Software, including hardware drivers can cause serious problems that may prevent your computer from booting properly. Microsoft cannot guarantee
that any problems resulting from the use of Third Party Software can be solved. Using Third Party Software is at your own risk.

Kindly follow the below methods and check if it helps.

Method 1:

I suggest you to update the Display adapter drivers.
Refer to the following article and update all the drivers available in Windows 10.

Windows 10



Method 2:

I suggest you to check if the issue occurs in Safe Mode with Networking. Follow the below steps:

Step 1:

To start Windows 10 in safe mode:

• 
  Press Windows + I keys on the keyboard to access settings menu.
  
• 
  Select Update &
  security and click on Recovery.
  
• 
  Go to Advanced startup and select
  Restart now.
  
• 
  After your PC restarts to the Choose an option screen, select
  Troubleshoot > Advanced options
  > Startup Settings >Restart.
  
• 
  After your PC restarts, select a startup setting as Safe Mode with Networking by pressing the corresponding number.
  

If the issue does not persists in Safe Mode with Networking, then perform a Clean Boot to check if any third party application is causing the issue, as Clean Boot helps in eliminating software conflicts.

Step 2:

Put the computer in Clean Boot and check if it helps. By setting your system in Clean Boot state helps in identifying if any third party applications or startup items are causing the issue.
