■Make sure your computer’s resolution setting is correct and dual 
display is not activated. Ideally, the resolution should be 
1024 × 768 (for the PowerLite 77c) or 800 × 600 (for the 
PowerLite S5 Series) to match the projector’s native resolution. If 
this option isn’t available, select one of the other compatible video 
formats listed on page 98. 
■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 correction as described on 
page 61 (PowerLite 77c only) or hold down the   or   
buttons on top of the projector until the image is rectangular.
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.
■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. 
						

							Solving Problems89
■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 60 for details.
■Make sure the cables are securely connected at both ends.
■Select the correct resolution; see “Compatible Video Formats” on 
page 98.
■If you’re projecting from a computer, press the 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 59.
The image is blurry.
■Adjust the focus using the focus ring.
■There may be dirt or smears on the lens. Clean the lens as 
described on page 74.
■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 57). 
You should be able to see the effect on the screen immediately. 
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. 
						

							90Solving Problems
■If further adjustment is needed, you can fine-tune the Tracking 
and 
Sync settings manually using the Signal menu as described 
on page 59. 
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. Or try 
projecting black text on a white background.
2. Adjust the 
Tracking to eliminate vertical stripes. 
3. Adjust the 
Sync to increase the sharpness of the image.
The colors of the image are not right.
■Try selecting a different Color Mode. See page 56 for 
instructions.
■If you’re displaying video, adjust the Color Saturation and Tint 
settings on the Image menu. See page 56 for instructions.
■Adjust the Brightness and Contrast settings on the Image 
menu. See page 56.
■Try adjusting the Color Adjustment setting on the Image menu. 
See page 57.
■Make sure the input signal setting on the Signal menu matches 
the signal from the connected device. If the image is too purple 
and you’ve connected a computer or RGB video device to the 
Computer (Component Video) 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, make sure the correct 
Video Signal is selected on the Signal message. See page 58 for 
details.
■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 65 and 
replace it, if necessary, as described on page 76.
note
Because of the different 
technologies used, your 
projected image may not 
exactly match the colors on 
your laptop or computer 
monitor.
