On most systems, the   key lets you toggle between the LCD 
screen and the projector, or display on both at the same time.
■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

The message Not Supported is displayed.
■Make sure the correct Input Signal is selected in the Video menu 
(see page 77).
■Make sure your computer’s resolution doesn’t exceed UXGA 
(1600 
× 1200), and the frequency is supported by the projector 
(see page 122). If necessary, change your computer’s resolution 
setting as described on the following page. 
Only part of the computer image is displayed.
■Press the Auto button on the remote control.
■Make sure the image Position setting is correct on the Video 
menu. See page 76 for more information.
■Make sure your computer’s resolution setting is correct. Ideally, it 
should be 1024 
× 768 to match the projector’s native resolution. 
If this option isn’t available, select one of the other compatible 
video formats listed on page 122.
■Windows:
Right-click the desktop, select 
Properties, click the Settings 
tab, and select a different resolution. 
■Macintosh:
On the Apple menu, choose 
Control Panels, then click 
Monitors and Sound. Select a different resolution.

created them for a different resolution. See your software 
documentation for specific information.
The image isn’t square, but trapezoid-shaped.
■If you’ve tilted up the projector by extending the legs, the image 
will be broader at the top. Hold down the left or right side of the 
Keystone button on the projector until the image is square.
■If the projector is angled toward the screen from the left or right, 
the image will be broader on one side. Center the projector in 
front of the middle of the screen, facing the screen squarely. 
						

							108Solving Problems
The image contains static or noise.
■Make sure the correct Input Signal is selected in the Video menu 
(see page 77).
■If you’re using a computer cable longer than 6 feet (2 meters), or 
an extension cable, the image quality may be reduced.
■Keep your computer and video cables away from the power cord 
as much as possible to prevent interference.
■The video signal may be split between the computer and the 
projector. If you notice a decline in the projected image quality 
when the image is displayed simultaneously on your laptop 
computer and the projector, turn off the laptop’s LCD display.
The image is blurry.
■There may be dirt or smears on the lens. Clean the lens as 
described on page 94.
■Adjust the focus using the focus ring.
■Make sure the lens is not fogged by condensation. You may need 
to wait before using the projector after moving it from a cold 
environment to a warm environment.
■Adjust the Sharpness setting on the Video menu (see page 76). 
When you change video settings, you should be able to see the 
effect on the screen immediately. If you’re projecting from a 
computer, you may also need to adjust the tracking and sync as 
described in the next section. If you don’t like the new settings, 
you can always select 
Reset to return to the factory default 
settings. 
						

							Solving Problems109
You see vertical stripes or the image still looks blurry after 
trying the solutions in the previous section.
■If you’re projecting from a computer and displaying an image that 
contains a lot of fine detail, you may notice one or more vertical 
stripes or bands, or some of the characters may look heavy or 
blurred. Press the 
Auto button on the remote control. This resets 
the projector’s tracking and sync settings.
■If further adjustment is needed, you can fine-tune the Tracking 
and 
Sync settings manually using the Video menu as described 
on page 76.
1. Fill the screen with an image containing fine detail when 
making these adjustments. For example, in Windows you can 
select a pattern to appear as your desktop background. If this 
option isn’t available, try projecting black text on a white 
background.
2. Adjust the 
Tracking to eliminate vertical stripes. 
3. Adjust the 
Sync setting to increase the sharpness of the 
image.  
						

							110Solving Problems
The colors of the image are not right.
■If you’re displaying a computer image, use the Color Mode 
option in the projector’s Video menu to adjust the color. If you’re 
displaying video, adjust the 
Color, Tint, and Color Mode 
settings on the Video menu.
■Try changing the Color Adjustment setting on the Advanced 
menu.
■Check your computer display settings to correct the color balance.
There is no sound.
■Make sure the A/V Mute button is not enabled.
■Try adjusting the Volume setting in the Audio menu (see 
page 78).
■If you’re using a VCR or other video source, make sure the 
volume is not turned all the way down or muted. Also, make sure 
the cables are connected correctly, as described in Chapter 4.
■If your presentation includes computer audio, make sure the 
volume control on your computer is not turned all the way down 
or muted. If you’re using the audio cable, make sure it is securely 
connected to both the projector and your computer’s   
headphone jack or   audio out jack (see page 52).
■Make sure the Windows volume controls on your computer are 
not turned all the way down or set to Mute. You may be able to 
check this by clicking the volume control in your Windows 
System Tray (lower right corner of the screen).
note
Because of the different 
technologies used, your 
projected image may not 
exactly match the colors on 
your laptop or computer 
monitor.

Solving EasyMP Problems 
An image displayed with EasyMP appears distorted.
Because of their resolution, some JPEG images cannot be displayed 
correctly. Some JPEG files from digital cameras cannot be previewed. 
Files with a high compression ratio may appear blurry.
In EMP SlideMaker, some PowerPoint files don’t appear in 
the file window.
EMP SlideMaker does not support PowerPoint 95. Files created in 
this version of PowerPoint must be opened and resaved in PowerPoint 
97 or later.
In EMP SlideMaker, your PowerPoint files don’t display 
thumbnails and can’t be pasted into scenarios.
If you use PowerPoint 97, make sure the MS Office JPEG converter 
has been installed. Run the Office 97 installer, display the 
Converters 
and Filters
 option, and install the JPEG filter. 
You can’t edit scenario files in EMP SlideMaker after they 
have been transferred to the memory card.
When scenario files are transferred, they are converted to the .SIT 
format. You can only edit scenarios before they are transferred (in the 
.SIC format). Open the scenario file saved on your hard drive, make 
any desired changes, then transfer the scenario again to your memory 
card. 
You don’t hear any audio when playing your scenario.
The playing of .WAV files is not supported.

Solving Problems with the Remote 
Control
The projector doesn’t respond to remote control commands.
■If you’re using the remote control for the first time, be sure to 
remove the protective tape from the battery tray as shown on 
page 22.
■The remote control’s battery may not be installed correctly or may 
be low on power. To change the battery, see page 23. 
■Make sure you are within 20 feet (6.1 meters) of the projector, 
and within range of the projector’s front or back sensor 
(approximately 30° to left or right and 15° above or below).
■Dim the room lights and turn off any fluorescents. Make sure the 
projector is not in direct sunlight. Strong lighting, especially 
fluorescent lights, may affect the projector’s infrared receivers.
■Turn off any nearby equipment that emits infrared energy, such 
as a radiant room heater.
You’ve connected a computer and you can’t control the 
mouse pointer with the remote control.
Make sure the cable is securely connected to both your computer’s 
USB port and the projector’s USB port (see page 53).
