Go into Multiple displays settings
  1. Duplicate these displays
  2. Extend these displays
  3. Show only on 1 (main display)
  4. Show only on 2 (second display)
If I plug in a second display my main display goes blank with only the second display showing the desktop. No problem.

If I select option 1 the the desktop is shown on both displays.

If I select option 2 the left half of the desktop is shown on the main display while the right half is shown on the second display.
