							Displaying and Adjusting the Image21
Focusing and Zooming Your Image
Turn the focus ring on the projector to sharpen the image. 
Turn the zoom ring on the projector to reduce or enlarge the image. 
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 29 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 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 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 triangular 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 
Setting menu, and press Enter. 
From the Setting menu, select 
Keystone and press Enter. Use 
the  pointer button on the remote control to adjust the 
keystone setting as needed. 
If the image becomes uneven, decrease the sharpness setting. (See 
page 47.)
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 30.

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,

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 49 for more information.
Using the A/V Mute Slide
You can use the A/V Mute slide to temporarily turn off the image and 
sound when you want to redirect your audience’s attention. 
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 
remote control or projector. 
note
You must be projecting an

any effect. The 
Auto button 
works only with computer 
images projected through the 
VGA port.
note
Lamp life results will vary 
depending on mode selected, 
environmental conditions, 
and usage.
Turn off this product when 
not in use to prolong the life 
of the projector.

Using the Direct Power On Function
The Direct Power On function enables faster setup. The projector will 
start up automatically when you plug it in; you won’t have to press the 
P
Power button. 
Follow these steps to enable Direct Power On: 
1. Press the 
Menu button on the remote control and select the 
Extended menu. 
2. Choose 
Operation and press Enter. 
3. Choose 
Direct Power On and press Enter.
4. Highlight 
On and press Enter. 
5. Press 
Esc or Menu to exit. The setting will take effect the next 
time you plug in the projector.
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 enable sleep mode, 
see page 57. 
note
If a power outage occurs 
when Direct Power On is 
enabled and the projector is 
plugged in, the projector will 
start when the power is 
restored.

							Using the Remote Control27
Controlling the Picture and Sound
You can use the remote control to preview and select your picture 
sources, temporarily turn off the picture and sound, freeze the action, 
zoom in on the picture, and adjust the volume. 
Switching Between Picture Sources
If your projector is connected to more than one computer and/or 
video source, you can switch between the different sources: 
■The easiest way to select your source is to press the Search button 
on the remote control (or the 
Source Search button on the 
projector) repeatedly until you see the image you want on the 
screen. 
■On the remote control, there are four Source buttons. Use them 
to switch between equipment connected to the port identified on 
each button.
After you select a source, the screen goes dark for a moment before the 
image appears.

							28Using the Remote Control
Turning Off the Picture and Sound
You can use the A/V Mute button on the remote control to turn off

■To turn off the picture and sound, press the A/V Mute button. 
The screen turns black. 
■To turn the image and sound back on, press the button again.
You can have the screen turn blue when you press the

■To stop the action and keep the current image on the screen, press 
the 
Freeze button. The sound continues. 
■To restart it, press the Freeze button again. 
note
This function pauses the 
image, but not the sound. 
Also, because the source 
continues to transmit 
signals, you won’t resume 
the action from the point 
you stopped it.

							30Using the Remote Control
Resizing Video Images
You can use the Resize button on the remote control to adjust how 
an image fits into the display area. 
For video images, press 
Resize to switch the aspect ratio between 4:3 
and 16:9, (and Normal for computer images). This lets you play 
certain digital video images or movies recorded on certain DVDs in 
16:9 widescreen format. 
For computer images, resizing is normally unnecessary, since the 
projector automatically resizes the image to make the best use of the 
display area. If you press the 
Resize button on the projector or remote 
control, the projector displays the image at the output resolution of 
the computer (which makes the image larger or smaller, depending on 
its resolution). If the resolution of the image is the same as the 
projector’s (1024 
× 768), pressing Resize has no effect. 
Adjusting the Color Mode
You can use the Color Mode button on the remote control to adjust 
the color, brightness, and other aspects of your image. 
Press the button repeatedly to select from the following settings:
Photo: For vivid, high-contrast still images in a bright room. 
Sports (video, S-video, or composite video only): For vivid TV 
images projected in a bright room. 
Presentation: For computer presentations (the default when 
projecting from a computer with analog video). 
Theatre: For optimizing movie images with increased contrast. 
Game: For increased brightness when playing video games or 
watching TV in a bright room. Emphasizes dark gradations.
sRGB: For matching the color palette of standard sRGB computer 
displays. 
Blackboard: For projecting accurate colors on a green chalkboard 
(adjusts the white point).
Customized: For manual color adjustment. (See page 46).
