Display configuration reverts to "Second screen only" after you resume from standby

Applies to: Windows 10, version 1809Windows 10Windows 8.1


On a Windows 10 or Windows 8-based laptop computer, you do the following:
  1. Plug in an external monitor.
  2. Change the display configuration to Second screen only (using the Windows logo key +P keyboard shortcut).
  3. Change the display configuration to Duplicate (using the Windows logo key +P keyboard shortcut again).
  4. Close the lid on the laptop computer.
  5. Unplug the external monitor.
  6. Open the lid on the computer.
  7. 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.
