If you’re using a PC notebook: 
■Hold down the Fn key on the keyboard and press the function 
key that lets you display on an external monitor. It may have an 
icon such as  , or it may be labelled 
CRT/LCD. Allow a few

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 
computer’s documentation or online help for details.
If you’re using Mac OS X: 
1. Open 
System Preferences. 
2. Click 
Display or Displays.
3. Click 
Detect Displays.
4. Make sure the 
VGA Display or Color LCD dialog box is selected.
5. Click the

Normal or Wide, depending on the size of your computer’s 
display panel.
■Make sure your computer is not set to display an extended 
desktop.
■Press the Esc button on the remote control to cancel the E-Zoom 
function.
■Make sure your computer’s resolution setting is correct. Ideally, it 
should be 1280 
× 800 to match the projector’s native resolution 
for the PowerLite 1730W, or 1024 
× 768 for the PowerLite 1720. 
If this option isn’t available, select one of the other compatible 
video formats listed on page 94.
■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 square, but keystone-shaped.
■If the top or bottom of the image is broader, press the   or   
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. 
■Enable the Auto Keystone feature to automatically fix the shape. 
See page 56. 
The image contains static or noise.
■If you’re using a computer cable longer than 6 feet, or an 
extension cable, the image quality may be reduced. Use a 
distribution amplifier for longer distances; you can purchase one 
from Epson (see page 12). 
						

							Solving Problems83
■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 notebook 
computer and the projector, turn off the notebook’s LCD display.
■Make sure the correct input signal is selected in the Signal menu 
(see page 55).
■If still images are jittery, turn on the Progressive setting in the 
Signal menu (see page 55).
The image is blurry.
■There may be dirt or smears on the lens. Clean the lens as 
described on page 68.
■Adjust the focus using the focus ring (see page 23).
■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.
■Make sure the projector is facing the screen squarely.
■Adjust the Sharpness setting on the Image menu (see page 53). 
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.
You see vertical bands 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 vertical bands or some 
of the characters may look heavy or blurred. Press the 
Auto 
button on the remote control to reset the projector’s tracking and 
sync settings. 
						

							84Solving Problems
■If further adjustment is needed, you can fine-tune the Tracking 
and 
Sync settings manually using the Signal menu, as described 
on page 55.
1. Fill the screen with an image containing fine detail, such as 
black text on a white background.
2. Adjust the 
Tracking to eliminate vertical bands. 
3. Adjust the 
Sync setting to increase the image sharpness. 
The image is too light or dark, or colors are incorrect.
■Press the Color Mode button to select a different color mode (see 
page 33). 
■Try adjusting the brightness and color settings in the Image menu 
(see page 52).
■Try changing the Brightness Control in the Settings menu (see 
page 56).
■For fine-art presentations, use the six-axis color adjustment as 
described on page 53 for precise control of the hue and saturation.
■Check your computer display settings to correct the color balance.
■The projector’s lamp may need to be replaced. See page 70 for 
instructions.
note
Because of the different 
technologies used, your 
projected image may not 
exactly match the colors on 
your notebook or computer 
monitor.

There is no sound, or the sound is not loud enough.
■Press the   button on the projector or remote control to increase 
the volume.
■Make sure A/V Mute is not enabled. (The A/V Mute button on 
the remote control may have been pressed.) 
■Make sure the A/V Mute slide is open.
■Try adjusting the Volume setting in the Setting menu (see 
page 56).
■If you’re using a DVD player or 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 on 
page 47.
■Make sure the audio cable is connected securely at both ends. For 
computer audio, connect the cable to your computer’s 
headphone jack or   audio out jack.
■Make sure the volume control on your computer is not turned all 
the way down or muted. In Windows, you may be able to use the 
volume control in your Windows system tray (lower right corner 
of the screen). On a Mac, you may be able to adjust the volume 
from your menu bar (top right corner of the screen) or via the 
volume control function keys. 
Solving Problems with the Remote 
Control
The projector doesn’t respond to remote control commands.
■The remote control’s batteries may not be installed correctly or 
may be low on power. To change the batteries, see page 28. 
■Make sure you are within about 20 feet (6 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). 
						

							86Solving Problems
■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. Also, turn off any nearby equipment that emits infrared 
energy, such as a radiant room heater. To avoid interference, you 
can also turn off the projector’s front or back sensor with the 
Remote Receiver setting (see page 57), but this may limit where 
you can use the remote control.
■Make sure the projector’s sensors have not been turned off with 
the 
Remote Receiver setting (see page 57).
■If the projector ID has been set, you may need to change the 
projector or remote control ID. See page 37.
■If any buttons are held for longer than 30 seconds, the remote 
enters sleep mode. Release any button that is held to wake the 
remote.

A
Projector Installation
This appendix provides guidelines on installing the projector in a 
permanent location, such as a theater or conference room.
The projector can be installed for four different viewing setups: front 
projection, ceiling projection, rear projection onto a semi-transparent 
screen, or rear/ceiling projection, as shown: 
To project from overhead, you’ll need the optional ceiling mounting 
hardware; see page 12 for ordering information. You’ll also need to 
select 
Front/Ceiling or Rear/Ceiling as the Projection option in the 
projector’s Extended menu to flip the image upside-down. To project 
from the rear, onto a semi-transparent screen, select 
Rear or 
Rear/Ceiling (see page 63).
Front projectionRear projection
Rear/ceiling projectionCeiling projection 
						

							90Projector InstallationIf you’re mounting the projector on the ceiling and you place it above 
screen level, you’ll have to tilt the projector down to position the 
image on the screen. This causes the image to lose its square shape. 
You can correct the distortion using the 
Keystone function in the 
projector’s menu system (see page 56).
If you place the projector so that the base of the lens is level with the 
bottom of the screen, the image should be square and you won’t have 
to adjust it. If you place the lens lower than the bottom of the screen, 
you’ll have to tilt the projector upward if you want to fill the whole 
screen with the image.
