The image isn’t square, but trapezoid-shaped.
If you’ve tilted the projector upward by extending the foot, the image 
will be broader at the top. If it is tilting downward, it will be broader 
at the base. To correct this, hold down the 
Shift button on the 
projector’s control panel and press the top or bottom 
Keystone 
button until the corners of the image are square.
The image contains static or noise.

If you are projecting from a 480i or 575i input source, turn on the 
Noise Reduction feature in the Advanced menu to reduce visual 
noise. See page 33.

Make sure the Video Signal, Input A, or Input B options in the 
Advanced menu are correct. See page 33.

If you’re using a computer cable longer than 6 feet (2 meters), or 
an extension cable, the image quality may be reduced. Also, 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 40.

Adjust the focus using the focus ring or display the test pattern by 
pressing the 
Pattern button.

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. 
						

							Solving Problems57

Adjust the Sharpness setting on the Video menu (see page 30). 
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.

Make sure the input signal matches the connected source. Check 
the settings for the 
Video Signal, Input A, and Input B options 
in the Advanced menu. (See page 33 for more information.)

If a computer is connected to the projector, make sure the correct 
resolution is selected. See your computer documentation. 
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 31.
The colors of the image are not right.

Select a different color mode by pressing the Colortune button 
on the projector or remote control or selecting the 
Color Mode 
option in the Video menu.

To increase or reduce contrast, try adjusting the Black Level and 
White Level in the Video menu.

If you’re displaying video, adjust the Color or Tint in the Video 
menu. 

Adjust the color contrast with the Color Adjustment option in 
the Video menu.
note
Because of the different 
technologies used, your 
projected image may not 
exactly match the colors on 
your laptop or computer 
monitor. 
						

							58Solving Problems

Make sure the input signal matches the connected source. Check 
the settings for the 
Video Signal, Input A, and Input B options 
in the Advanced menu. If the 
Input B option is set to RGB when 
the projector is receiving component video signals, the images 
may look too green. If the 
Input B option is set to YCbCr or 
YpbPr when a computer is connected, the images may look too 
purple. (See page 33 for more information.)

If the input source is a computer, check its display settings to 
correct the color balance.

If the lamp is running out, the image will become darker. You 
may need to replace the lamp.
Solving Problems with the Remote 
Control
The projector doesn’t respond to remote control commands.

Make sure you are within 30 feet (9 meters) of the projector, and 
within range of the projector’s front or back sensor 
(approximately 30° to the left or right and 15° above or below).

The remote control batteries may not be installed correctly or may 
be low on power. Try replacing the batteries.

Dim the room lights and turn off any fluorescent lights. 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.

Appendix A: Connecting the 
Projector to a Computer
This appendix explains how to connect a laptop or desktop PC or 
Macintosh to the projector’s VGA or DVI interface. Before you start, 
make sure you have the proper cables, identified on page 2.
Connecting to a VGA Computer Source
You can connect the projector to any computer that has a standard 
video output (monitor) port, including PC notebook and laptop 
computers, Macintosh PowerBooks, and hand-held devices. For this 
connection, you’ll need an optional VGA computer cable. (See 
page 2.)
1. Make sure your computer and the projector are turned off.
2. If you are connecting to a desktop computer, disconnect the 
monitor cable from the video port on the back of the computer.
3. Connect one end of the computer cable to the projector’s 
Input B 
port.

							62Appendix A: Connecting the Projector to a Computer4. Connect the other end of the computer cable to your computer’s 
video port.
If you’re using a Macintosh and the cable doesn’t fit, you may 
need to use the Macintosh desktop adapter. 
To use the adapter, remove its cover as 
shown and set its DIP switches according 
to the resolution you want to use, such as 
16-inch mode. See your Macintosh 
documentation for instructions.
Replace the cover and connect the 
adapter to the free end of the computer 
video cable. Then plug the cable (with 
the adapter) into the video port on your 
Macintosh.
5. Tighten the screws on the connectors.
Now you are ready to plug in your projector and turn it on. See page 8 
for instructions.
Be sure to check the setting for the 
Input B port in the Setting menu 
(as described on page 33) to make sure it is correct for your computer. 
note
You can purchase a desktop 
adapter from EPSON; see 
page 4. 
						

							Appendix A: Connecting the Projector to a Computer63
Connecting to a DVI Computer Source 
The projector’s DVI (Digital Visual Interface) port receives pictures 
directly from your computer in digital format. This lets the projector 
display images of greater clarity than can be achieved using a standard 
analog VGA connection. You’ll need one of the optional DVI cables 
described on page 4.
Follow these steps:
1. Make sure your computer and the projector are turned off.
2. If you are connecting to a desktop computer, disconnect the 
monitor cable from the video port on the back of the computer. 
3. Connect one end of the DVI cable to the projector’s 
DVI port.
4. Connect the other end of the cable to your computer’s video port.
5. Tighten the screws on the connectors.
Now you are ready to plug in your projector and turn it on. See page 8 
for instructions.
Be sure to check the setting for the 
Input A port in the Setting menu 
(as described on page 33) to make sure it is correct for your computer.

Appendix B: Notices
This chapter includes safety instructions and other important information 
about your EPSON PowerLite projector.
Important Safety Instructions
Follow these safety instructions when setting up and using the projector:

Do not place the projector on an unstable cart, stand, or table.

Do not use the projector near water or sources of heat.

Use the type of power source indicated on the projector. If you are not 
sure of the power available, consult your dealer or power company.

Place the projector near a wall outlet where the plug can be easily 
unplugged.
Placez l’appareil près d’une prise de courant où la fiche peut être débranchée 
facilement.

Insert the projector’s three-wire grounding-type plug into a properly 
grounded outlet. If you have a two-prong outlet, contact an electrician 
to replace it. Do not hold the plug with wet hands.

Take the following precautions for the plug. Failure to comply with 
these precautions could result in sparks or fire: Do not insert the plug 
into an outlet with dust present. Insert the plug firmly into the outlet.

Do not overload wall outlets, extension cords, or integral convenience 
receptacles. This can cause fire or electric shock.

Do not place the projector where the cord can be walked on. This may 
result in fraying or damage to the plug.

Unplug the projector from the wall outlet before cleaning. Use a damp 
cloth for cleaning. Do not use liquid or aerosol cleaners.

Do not block the slots and openings in the projector case. They provide 
ventilation and prevent the projector from overheating. Do not operate 
the projector on a sofa, rug, or other soft surface, or in a closed-in 
cabinet unless proper ventilation is provided.
