Source Search button on the 
projector or the remote control to select the correct source. Allow 
a few seconds for the projector to sync up after pressing the 
button.

Only part of the computer image is displayed.
■If you’re projecting from a computer or RGB video device, press 
the 
Enter/Auto button on the remote control. If this doesn’t 
work, you may need to adjust the 
Position setting in the Signal 
menu. See page 55 for more information.
■If you’ve enlarged part of the image using the E-Zoom button on 
the remote control, press the 
Esc button to cancel zooming and 
return to full display.
■Try pressing the Aspect button on the remote control to select a 
different aspect ratio (4:3, 16:9, or another available setting).
■Make sure your computer’s resolution setting is correct and dual 
display is not activated. Ideally, it should be 1024 × 768 to match 
the projector’s native resolution. If this option isn’t available, 
select another compatible video format. See page 105. 
■Windows:
Right-click the desktop, select 
Properties, click the Settings 
tab, and select a different resolution. 
■Macintosh OS X:
On the Apple menu, choose 
System Preferences, then 
click 
Display or Displays. Select a different resolution.
■You also may need to modify existing presentation files if you 
created them for a different resolution. See your software 
documentation for specific information.
The image isn’t rectangular, but trapezoid-shaped.
■Make sure the projector isn’t placed off to one side of the screen, 
at an angle, or the image won’t be rectangular. Place it directly in 
front of the center of the screen, facing the screen squarely.
■If you’ve tilted the projector upward, the image will be broader at 
the top. Turn on 
Auto Keystone as described on page 56 or hold 
down the   or   buttons on top of the projector until the 
image is rectangular. 
						

							Solving Problems83
The image contains static or noise.
■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 separated 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.
■If you’re projecting from a composite or S-Video source, check 
the 
Video Signal setting in the Signal menu. In most cases, leave 
it set at 
Auto. If you’re using a 60-Hz PAL video source, change 
this setting to 
PAL60. See page 56 for details.
■Make sure the cables are securely connected at both ends.
■Select the correct resolution; see “Compatible Video Formats” on 
page 104.
■If you’re projecting from a computer, press the Enter/Auto 
button on the remote control or the 
Enter button on the 
projector to adjust tracking and sync automatically. If that doesn’t 
work, try adjusting the 
Sync and Tracking settings in the Signal 
menu. See page 55.
The image is blurry.
■Adjust the focus using the focus ring. See page 38.
■Try cleaning the lens as described on page 70.
■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.
■Make sure the projection distance is within the range described on 
page 16.
■Adjust the Sharpness setting on the Image menu (see page 54). 
You should be able to see the effect on the screen immediately.  
						

							84Solving Problems
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 
Enter/Auto button on the remote control to 
automatically reset the projector’s tracking and sync settings.
■If necessary, you can manually adjust the Tracking and Sync 
settings on the Signal menu as described on page 55. 
To help you adjust these settings, fill the screen with a detailed 
image, such as a desktop background pattern or black text on a 
white background. Adjust the 
Tracking setting to eliminate 
vertical stripes; adjust the 
Sync setting to increase the sharpness.
The colors of the image are not right.
■Try selecting a different Color Mode. See page 53 for 
instructions.
■If you’re displaying video, adjust the Color Saturation and Tint 
settings on the Image menu. See page 53 for instructions.
■Adjust the Brightness, Contrast, and Color Adjustment 
settings on the Image menu. See page 53.
■Make sure the input signal setting on the Signal menu matches 
the signal from the connected device. See page 54 for details.
If the image is too purple and you’ve connected a computer or 
RGB video device to the 
Computer1 or Computer2 port, select 
Computer as the input source. If you’ve connected a component 
video device to one of these ports, select 
Component Video. 
If you’re projecting from a composite video or S-Video source, 
select the correct 
Video Signal is selected on the Signal menu. 
■Check your computer display settings to correct the color balance.
■If the image seems dark, the lamp may be nearing time for 
replacement. Check the lamp hours as described on page 60 and 
replace it, if necessary, as described on page 72.
note
Because of the different 
technologies used, your 
projected image may not 
exactly match the colors on 
your laptop or computer 
monitor.

volume is not turned all the way down or muted. Also, make sure 
the cables are connected correctly, as described in Chapter 1.
■Make sure the audio cable is connected to the correct audio port. 
See page 22 or page 29.

Solving Problems with the Remote 
Control
The projector doesn’t respond to remote control commands.
■Make sure you are within 20 feet 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).
■If a button on the remote control is held for more than 30 
seconds, the remote enter sleep mode. Press another button for 
normal operation.
■The remote control batteries may not be installed correctly or may 
be low on power. Replace the batteries as described on page 48.
■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. If you still have trouble using the remote control, disable 
one of the remote receivers using the Settings menu to block 
interference from bright light. See page 56 for details.
■Turn off any nearby equipment that emits infrared energy, such 
as a radiant room heater.
You have lost the remote control.
You need the remote control to access many projector features. If you 
have lost it, you can order another from Epson. See page 88 for 
details.
