Monitor Primary monitor layout switches upon second monitor power off

Hi alts63,

One of the possible reasons why your primary monitor layout switches is that the rotation lock option is turned on. In order to turn that off and fix the issue, please follow these steps:

1. Press Windows key + A on your keyboard to open Action Center.
2. Click the Expand button.
3. Click the Rotation lock to turn it off.
