- Depending on your computer’s video card, you might need to use the Display utility in the Control Panel to make sure that both the LCD screen and external monitor port are enabled. See your computer’s documentation or online help for details.
- Make sure the projector is connected to your Macintosh.
- Select System Preferences from the Apple menu and click Display or Displays.
- Click Detect Displays.
- Make sure the VGA Display or Color LCD dialog box is selected.
- Click the Arrangement or Arrange tab. (If you don’t see this tab, make sure it isn’t hidden by another window.)

Some LCD monitors may not be able to display the image correctly. If you have trouble displaying the image, connect a multiscan monitor. If you’re projecting computer images, make sure the computer’s refresh rate is set to 60 Hz or greater.
