Switching Main Display in Windows 10
Posted by Bart Chellis, Last modified by Bart Chellis on 25 September 2017 12:43 PM
One monitor is considered the primary monitor on a computer set up with dual monitors connected.  The primary monitor is the one that applications open on by default and the one that displays the notification area in the lower-right corner of the screen.  

Follow these steps to switch which monitor is the primary display:
  1. Right-click the desktop and select Display settings

  2. In the Display settings dialog, click on the Identify button to have a number presented on each monitor to help you identify which screen is #1 (primary) and which is #2 (secondary)

  3. Select icon representing the monitor that you want to set as primary (usually #2)

  4. Scroll to the bottom of the Display settings dialog and place a check in "Make this my main display".  The screen will flash briefly and your selected monitor should now be your primary display.

    Note: If "Make this my main display" already has a checkmark in it and is disabled (grayed out), then the monitor you have selected in step 3 is already set as the primary.

  5. Close the Display settings dialog
