Troubleshooting Display Problems
Follow these guidelines if you’re having trouble displaying an image. 
You Can’t Project an Image
If you don’t see the image you are trying to project, try the following: 
■Make sure the cables are connected correctly, as described 
beginning on page 39.
■Make sure the  Ppower light is green and not flashing and the 
A/V Mute slide is open.
■If you’ve connected more than one computer and/or video source, 
you may need to press the 
Source Search button on the 
projector’s control panel or 
Search button on the remote control 
to select the correct source. (Allow a few seconds for the projector 
to sync up after pressing the button.)

The Projector and Notebook Don’t Display the 
Same Image
If you’re projecting from a noteb ook, and you can’t see your image on 
the projection screen and on your  computer at the same time, follow 
these guidelines.
If you’re using  a PC notebook:
■On most systems, there’s a function key that lets you toggle 
between the LCD screen and the projector, or display on both at 
the same time. It may be labeled 
CRT/LCD or have an icon such as 
. You may have to hold down the 
Fn key while pressing it. 
Allow a few seconds for the projector to sync up after changing 
the setting. 
■If the function key doesn’t permit you to display simultaneously 
on both screens, you should check your monitor settings to make 
sure both the LCD screen and the external monitor port are 
enabled. 
From the Control Panel, open the 
Display utility. In the Display 
Properties dialog box, click the 
Settings tab, then click 
Advanced. The method for adjusting the settings varies by 
brand; you may need to click a 
Monitor tab, then make sure the 
external Monitor port is set as  your primary display and/or 
enabled. See your computer’s do cumentation or online help for 
details.
If you’re using Mac OS X:
You may need to set up your system  to display on the projector screen 
as well as the LCD screen. Make su re your projector is connected and

page 24.
■To focus or zoom your image, see page 24.
■If the image isn’t square, see page 25.

Adjusting the Height of Your Image
If the image is too low on the screen, you can use the front adjustable 
foot to raise it. 
1. Stand behind the projector. Press the foot release lever up and lift the front of the projector.
2. Once the image is positioned where you want it, release the lever  to lock the foot in position.
3. If necessary, you can fine-tune the height or level of the image by  turning the projector’s adjustable rear feet. 
Raising the projector causes the im age to distort or “keystone,” but 
you can correct the shape as described on page 25. 
Focusing and Zooming Your Image
Turn the focus ring on the projector to sharpen the image. 
Turn the zoom ring on the projecto r to reduce or enlarge the image. 
Focus Zoom  
						

							
Displaying and Adjusting the Image25
If the image still isn’t large enough, you may need to move the 
projector farther away from the screen. You can also use the 
E-Zoom 
buttons on the remote control to zoom in on a portion of the image. 
See page 33 for instructions.
Adjusting the Image Shape
In most cases, you can maintain a square or rectangular image by 
placing the projector directly in front of the center of the screen with 
the base of the lens level with the bottom of the screen. 
Even if the projector is slightly tilted (within a range of 30° up or 
down), the projector has an automatic keystone correction function 
that detects and corrects vert ical keystone distortion.
It takes about one second after projection starts for the image to be 
corrected. During this time, a ve rtical keystone correction gauge 
appears on the screen.
If your image is still distorted, you can correct it using the Keystone 
buttons on the projector’s control panel or the projector’s Setting 
menu.

Using Keystone Correction
To adjust your image when it is wider on the top or bottom, do the 
following:
■Press one of the two keystone correction buttons on the 
projector’s control panel, as shown below. Continue pressing the 
button until you are satisfied with the shape of the image.
■Or press the Menu button on the remote control or projector, 
select the 
Settings menu, and press Enter. 
From the Settings menu, select 
Keystone and press Enter. Use 
the  pointer buttons on the remote control to adjust the 
keystone setting as needed. 
If the image quality declines (for  example, lines or edges look 
jagged), reduce the sharpness setting. See page 65.
tip
You can display a test 
pattern to help align the 
image (see page 68).

Correcting Computer Images
If you’re connected to a computer and the image doesn’t look right, 
press the 
Auto button on the remote control or the Enter button on 
the projector. This automatically resets the projector’s tracking, sync, 
resolution, and position settings. 
If the 
Auto button doesn’t correct the problem, you may need to 
adjust the tracking or sync using the projector’s Signal menu. See 
page 66 for more information.
note
The Auto button works only 
with computer images 
projected through the VGA 
port.

Using the Remote Control
The projector includes a number of tools to enhance your 
presentation. All of them can be accessed using the remote control, 
which lets you operate the projecto r from anywhere in the room—up 
to 20 feet away. 
You can use the remote control to adjust the picture and sound 
(page 31) or to adjust the color mode for various environments 
(page 35). You can also use it as a wireless mouse when projecting 
from a computer (page 36) or as a pointer to highlight your 
presentation (page 37). 
This chapter covers:
■Using the remote control
■Controlling the picture and sound
■Operating your computer with the remote control
■Highlighting your presentation
