It is always recommended to use the updated drivers. 

Many of us don’t update windows or drivers because it takes high-speed internet and lots of data to update. 

Using outdated drivers and windows can also crash the system and may be the reason for this issue.

5. Check For Viruses.

SAFETY IS A GOOD BUSINESS.

I always prefer to use a good antivirus for my system. As our system will expose daily to lots of viruses and malware. 

So it is quite important to protect our system from viruses and keep our data secure.

If you are using Windows 10, then you can use Windows Defender. But make sure that windows defender is updated and after that, you can perform a full scan to check the viruses.

There are lots of viruses and malware that corrupt the system files that may cause issues with your second screen display.

6. Reinstall/Update Windows

If the above troubleshoots didn’t work for you, then the chances are there is some issue within the hardware.

But, to give it a last try to check the software issue, you can reinstall the windows, Or, if there is an updated version of windows available then you can install it to make sure that there is no issue from the software end.

Reinstalling windows may lose your data. So make sure that you take a backup first.

Also, while reinstalling the windows, take help from professionals. So that you can install the windows correctly.
