Problem Solving

■

If the function key doesn’t let you display simultaneously on both screens, you might 
need to use the Display utility in the Windows Control Panel to make sure that both the 
LCD screen and external monitor port are enabled. From the Windows Control Panel, 
open the 

Display

 utility. In the Display Properties dialog box, click the 

Settings

 tab, 

then click 

Advanced

. The method for adjusting the setting varies from computer to 

computer; you may need to click a 

Monitor

 tab, then make sure the external Monitor 

port is set as your primary display or enabled. See your computer manual or online help 
for details.

If you’re using Mac OS X:

1. Open the 

System Preferences

 utility and select 

Displays

.

2. Select the 

VGA Display

 or 

Color LCD

 option, if necessary. 

3. Click the 

Arrange

 or 

Arrangement

 tab. 

4. Check the 

Mirror Displays

 checkbox. (See your computer manual for details.)

If you’re viewing still images and you notice flickering or horizontal lines, turn on the 

Progressive

 setting (see page 42). 

■

Make sure your cables are securely connected at both ends.

If you’re using an extension cable, you may pick up interference if the cable is not 
adequately shielded. You may need to use a signal amplifier for longer cables.

If you’re displaying the same image on your computer and projector screen, try turning 
off your laptop’s LCD display (see page 72).
