When connected to a PC or Mac, the cursor doesn’t appear on the Cintiq when setting up the Cintiq Companion 2 as an extended display. What do I do?

Go to the Control Panel on your PC or Preferences on your Mac.  Select Display and change the Cintiq Companion to the primary display and the cursor will appear on the Cintiq. The Cintiq Companion 2 has to be the primary display.
