If you are using a Macintosh Laptop with OS 9.x or earlier:

1. From the Apple menu, select Control Panels, click Monitors and Sound.
2. Click the Arrange icon, and then drag one monitor on top of the other. Note: If the arrange icon isn't available, you may need to select one of the Simulscan resolution settings. Click the monitor icon and then select a Simulscan resolution from the ones in the Resolution box. (Allow a few seconds for the projector to sync up after making the selection.)

If you are using a Macintosh Laptop with OS X:

1. Select System Preferences from the Apple Menu and Click Displays.
2. Click Detect Displays.
3. To display the entire desktop on both your projector screen and LCD screen, click the Arrange Tab.
4. Click Mirror Displays in the lower corner of the screen. One of the monitor icons automatically moves on top of the other.
