20 Displaying and Adjusting the Image
The Projector and Notebook Don’t Display the Same Image
If you’re projecting from a notebook, and you can’t see your image on
the projection screen and on your computer at the same time, follow
these guidelines.

If you’re using a PC notebook:

■On most systems, there’s a function key that lets you toggle
between the LCD screen and the projector, or display on both at
the same time. It may be labeled CRT/LCD or have a n icon su ch as
. You may have to hold down the Fn key while pressing it.
Allow a few seconds for the projector to sync up after changing
the setting.
■If the function key doesn’t permit you to display simultaneously
on both screens, you should check your monitor settings to make
sure both the LCD screen and the external monitor port are
enabled.
From the Control Panel, open the Display utility. In the Display
Properties dialog box, click the Settings tab, then click
Advanced. The method for adjusting the settings varies by
brand; you may need to click a Monitor tab, then make sure the
external Monitor port is set as your primary display and/or
enabled. See your computer’s documentation or online help for
details.

If you’re using Mac OS X:

You may need to set up your system to display on the projector screen
as well as the LCD screen. Make sure your projector is connected and
follow these steps:
1. From the Apple® menu, select System Preferences, then select
Displays.
2. Click Detect Displays.
3. Make sure the VGA Display or Color LCD dialog box is selected.
