documentation for specific information.
■If you’re projecting a wide panel computer image, adjust the 
Resolution setting (see page 116).
■If you’re projecting an image from a computer with dual display 
activated, turn dual display off.
The image isn’t square, but keystone-shaped.
If the image isn’t square or rectangular, adjust its shape as described on 
page 58.
The image contains static or noise.
■Make sure the cables are securely connected. 
						

							154Solving Problems
■If you’re using a computer cable longer than 6 feet (1.8 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 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 118).
■If you’ve used the Quick Corner or Keystone adjustment, you 
may need to decrease the 
Sharpness setting in the Image menu 
(see page 115).
■If you’re projecting from a computer, make sure its signal is 
compatible with the projector. See page 174.
■If you’re using the Split Screen function, you may need to set the 
Resolution setting in the Signal menu to 
Auto (see page 117).
■Press the Auto button on the remote control or the Enter button 
on the projector to reset the projector’s Tracking, Sync, and

■If the projector is angled sharply toward the screen, it may not be 
possible to focus the entire image. Move the projector to position 
it more directly in front of the screen.
■Lower the projection angle to reduce the amount of keystone 
correction required.
note
You must be projecting an 
image for the 
Auto button 
to have any effect. It works 
only with computer images 
projected through the VGA 
port. 
						

							Solving Problems155
■Make sure the projector is within the proper range (projection 
distance) from the screen (see page 170).
■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.
■If you’re projecting from a computer, you may need to adjust the 
tracking and sync settings as described in the next section. 
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 or the 
Enter button on the 
projector to reset the projector’s Tracking, Sync, and Position 
settings.
■If further adjustment is needed, you can fine-tune the Tracking 
and 
Sync settings manually using the Signal menu, as described 
on page 117.
1. Fill the screen with an image containing fine detail, such as a 
pattern to appear as your desktop background, or try 
projecting black text on a white background.
2. Adjust the 
Tracking to eliminate vertical bands. 
3. Adjust the 
Sync setting to increase the image sharpness.

Volume setting in the Settings menu (see 
page 120).
■Make sure A/V Mute is not enabled. (The A/V Mute button may 
have been pressed.) 
■If your presentation includes computer audio, make sure the 
volume control on your computer is not turned all the way down 
or muted. In Windows, you may be able to check this by clicking 
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.
■If you’re using a DVD player or other video source, make sure the 
cables are connected correctly, as described on page 46.
note
Because of the different 
technologies used, your 
projected image may not 
exactly match the colors on 
your notebook or computer 
monitor. 
						

							Solving Problems157
■If you’re using a computer audio cable, make sure it is connected 
to your computer’s  headphone jack or   audio out jack. 
Connect the other end to the projector as described on page 46.
■If you’re using an HDMI cable and you hear no sound, set your 
equipment to PCM output.
■If your equipment is connected through the LAN port, or the 
HDMI port with the PowerLite G5550NL/G5650WNL/
G5950NL, make sure you’ve set the 
Audio Input setting 
correctly. See page page 119.
Nothing Appears on an External Monitor
■The only images that can be displayed on an external monitor are 
computer images connected through the 
Computer1, 
Computer2 (G5550NL/G5650WNL/G5950NL only) or BNC 
input ports. See page 45.
■If you are using the Split Screen function, the computer image 
must be on the left side if you want to display it on an external 
monitor. See page 62.
Solving Network Problems
The projector does not send e-mail alerts even though the 
e-mail notification function has been turned on.
■Make sure the mail notification function is set correctly in the 
configuration menu. See page 98.
■Set Standby Mode to Communication On in the Extended 
menu. Otherwise, the projector cannot send e-mails when it is in 
Standby mode (when the power is off).
■If a critical problem develops with a projector which causes it to 
suddenly stop working, it may not be possible for the projector to 
send a message. 
						

							158Solving Problems
■Make sure the projector is plugged in.
■Make sure the LAN cable is connected correctly. Reconnect it if it 
is not connected or it is not connected correctly (see page 76).

Solving Problems With the Remote 
Control
The projector doesn’t respond to remote control commands.
■Point the remote control towards the receiver.
■Make sure the projector and remote control IDs match. To 
operate all projectors by remote control regardless of ID settings, 
set the ID switch on the side of the remote control to 
Off.
■The remote control’s batteries may not be installed correctly or 
may be low on power. To change the batteries, see page 142. 
■Make sure you are within about 49 feet (15 meters) of the 
projector and within range of the projector’s front or back sensor.
■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. If necessary, use the 
Remote Receiver setting to disable the projector’s front or back 
sensor if it continues to pick up interference (see page 120).
■Make sure the Remote Receiver setting isn’t disabling both of 
the projector’s sensors (see page 120).
■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.
■When the optional remote control cable is connected, the remote 
control light-emitting area and the projector’s remote receiver are 
disabled. If you’re not using the cable, make sure it is 
disconnected from both the remote control and the projector.
■Make sure the Remote Control Type setting is correct. See 
page 126.
