Original KB number: 2890797
On a Windows 10 or Windows 8-based laptop computer, you do the following:
- Plug in an external monitor.
- Change the display configuration to Second screen only (using the Windows logo key +P keyboard shortcut).
- Change the display configuration to Duplicate (using the Windows logo key +P keyboard shortcut again).
- Close the lid on the laptop computer.
- Unplug the external monitor.
- Open the lid on the computer.
- Plug the external monitor back in.
In this scenario, the display configuration may revert to Second Screen only instead of remaining in Duplicate mode.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
To work around this problem, use the Windows logo key ) +P keyboard shortcut to change the display configuration back to Duplicate mode.
