If the SmartBoard is not showing what is on the computer screen you will need to "Mirror" the displays. 


To do this:

  1. Go to System Preferences
  2. Click on Displays
  3. If your computer is connected to the SmartBoard you should see a tab at the top called "Arrangement", select this tab
  4. towards the bottom of the window you should see an option to Mirror displays.

Once you have done this you should now see the same image on both your SmartBoard and your computer screen.
