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 45.
■Make sure the Power light is green and not flashing and the lens 
cap is off. 
■If you’ve connected more than one computer and/or video source, 
you may need to press one of the

Adjusting the Image 
Once you see your image, you need to make certain adjustments:    
■If the image is too high or too low, you can reposition it. See 
below.
■If you have quick setup enabled on the projector, see page 25. 
■To focus or zoom your image, see page 25. 
■If the image isn’t square, see page 26.
■If a computer image displays incorrectly, see page 28. 
If you need to fine-tune the image and/or sound, see Chapter 4.
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 blue 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 the image by 
turning the projector’s rear feet. 
Raising the projector causes the image to distort or “keystone,” but 
you can manually correct the shape as described in the next section.

Using Quick Setup
You can use the Quick Setup button on the projector or the remote 
control to quickly and automatically set up the projector’s focus, 
zoom, and shape, as well as the Wall Shot setting. All you need to do is 
position your projector, then press 
Quick Setup. Make sure you 
enable Quick Setup for all of the settings you want to use as described 
on page 76.
Focusing and Zooming Your Image 
Use the Focus buttons on the projector or remote to sharpen the 
image. 
Use the 
Zoom buttons on the projector or remote to reduce or enlarge 
the image. Press the 
W button on the projector or the top zoom 
button on the remote to increase the size, and the 
T button on the 
projector or bottom zoom button on the remote to decrease it. 
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 38 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 40° up or 
down), the projector has an automatic keystone correction function 
that detects and corrects vertical keystone distortion.
It takes about one second after projection starts for the image to be 
corrected. During this time, a vertical keystone correction gauge 
appears on the screen. 
If your image is still distorted, you can correct it using either of these 
methods: 
■If the image has two parallel sides but is wider on one side (top, 
bottom, left, or right), you can correct it using the Keystone 
buttons on the projector’s control panel (see page 27) or the 
projector’s Keystone menu (see page 27).
■If the image has no parallel sides, you can adjust its shape using 
Quick Corner (see page 36). 
You cannot use both keystone correction and Quick Corner at the 
same time.

Using Keystone Correction
To adjust your image when it is wider on one side, do the following:
■Look at the shapes of the icons on the projector’s four keystone 
buttons. Press the button whose icon is the opposite of the shape 
of your screen image. Continue pressing the button until you are 
satisfied with the shape of the image.
■Or press the Menu button on the remote control, select the 
Setting menu, and press Enter. From the Setting menu, select 
Keystone and press Enter, select H/V Keystone and press Enter, 
then select 
Horiz./Vert./Height and press Enter. Select 
V-Keystone (for vertical keystone distortion) or H-Keystone 
(for horizontal keystone distortion) and press 
Enter. Use the 
pointer button on the remote control to adjust the keystone 
setting as needed. 
note
The image will be slightly 
smaller after adjusting. If 
it’s important to maintain 
the correct aspect ratio, use 
the menu system to perform 
keystone correction, then use 
the remote’s 
Resize button 
to adjust the aspect ratio. See 
page 65.

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. This automatically 
resets the projector’s tracking, sync, resolution, and position settings. 
If vertical bands appear in the projected image and the 
Auto button 
doesn’t correct the problem, hold down the 
Shift button on the 
projector’s control panel while pressing either the 
Tracking + or the 
Tracking - button.
If the image appears fuzzy or flickers and the 
Auto button doesn’t 
correct the problem, hold down the 
Shift button while pressing either 
the 
Sync + or Sync - button on the projector. 
note
You must be projecting an 
image for this button to have 
any effect. The 
Auto button 
works only with computer 
images.

Shutting Down the Projector
When you’ve finished using the projector, follow the recommended 
procedure to shut it down. This extends the life of the lamp and 
protects the projector from possible overheating. 
1. Turn off any equipment plugged into the projector. 
2. To turn off the projector, press the red P
Power button on the 
projector or remote control. 
You see a confirmation message. (If you don’t want to turn it off, 
press any other button.)
3. Press the P
Power button again. The projector beeps twice, the 
lamp is turned off, and the 
Power light flashes orange for about 
30 seconds as the projector cools down. After the projector has 
cooled, the orange light stays on and the exhaust fan shuts off.
If you want to turn the projector on again, wait until the orange 
light stops flashing. Then press the P
Power button.
4. If you extended the adjustable front foot, press up on the blue 
foot release lever to retract it.
5. Replace the lens cap and unplug the power cord.
6. If you’re using a remote control, set its 
ON/OFF switch to OFF.
note
You can set the projector to 
automatically turn off the 
projector lamp and enter 
“sleep mode” when it has not 
received any signals for 30 
minutes. This conserves 
electricity, cools the 
projector, and extends the 
life of the lamp. If you want 
to start projecting again, 
press the P Power button. 
If you are done using the 
projector, unplug the power 
cord. To turn off sleep 
(standby) mode, see page 75. 
Power button
caution
Turn the projector off when 
not in use. Continuous 
24-hour-a-day use may 
reduce the projector’s overall 
life.
