In order to increase the productivity of work, an extra monitor is added on Windows 10. Sometimes, even to get an immersive gaming experience, an extra display is added to Windows 10 system. However, many Windows 10 users have had issues with this and it has not quite worked the way it should. Users have reported an error message which states that their second monitor cannot be detected, although the monitor works and the video output which is connected is working fine.
If you have also been through this problem, then don’t lose hope. This is not a very difficult problem, and it can be fixed. If you are wondering why Windows 10 can’t detect the second monitor, then here’s the reason behind it – This is usually a driver problem. When the video driver is out of date, or faulty/incorrect, then Windows 10 will not be able to extend the desktop to second display. Also, the problem can occur due to monitor driver.
So how to fix second monitor not detected on Windows 10 error?
We tell you 2 methods that you can try out.
