Why is my Merlyn overlay on the wrong screen?

Q: Why is my Merlyn overlay on the wrong screen?

A: Origin places the overlay on the secondary or extended display. 

Solutions:

• On Windows:
  • Right-click on the desktop and select “Display Properties”.  
  • Click on the monitor you wish to make primary, and check the “Make this my primary display” box for the display you don't want Merlyn to show on.
• On Mac:
  • Open “System Settings” and select “Displays”.  
  • Press “Arrange…” and move the menu bar to your desired primary display to choose the screen Merlyn will not show on.
