This means that the computer is "extending" the display not duplicating it . . . in other words it's treating the projector like a second monitor that is 'attached' at one edge to you main display. Rolling the mouse beyond either the left or the right edge of your computer's screen will make the mouse cursor show up on the projector. 
  1. Minimize your programs so you can see the desktop background on your system. 
  2. In an open space on the background (no icons) R-click, then select "Screen Resolution". 
  3. At "Multiple Displays:" click the dropdown and select "Duplicate these Displays". 
  4. Now what you seen on your computer should also be up on the big screen. 

    [Note: If you are a power user, you may prefer having the displays extended so you can work while your students watch an instructional video.]
