Displaying and Adjusting 
the Image
Whether you’re presenting from a computer or video equipment,
or with the optional EasyMP.net, you need to follow some basic steps 
to display your image on the screen. 
Follow the guidelines in this chapter to: 
■Turn on the projector and select the image source
■Adjust the image
■Shut down the projector

Projecting the Image
Make sure your projector and other equipment are set up as described 
in Chapter 1. Then follow the instructions below to start the projector 
and display an image. 
Turning on the Projector
If you turn on your connected computer or video equipment before 
starting the projector, the projector automatically detects and displays 
the image source. If you turn on the projector first, or have multiple 
pieces of connected equipment, you may have to select the image 
source manually (see page 34).
Follow these steps to turn on the projector:
1. Remove the lens cap. 
2. Plug in the projector, as shown below. 
The Ppower light stops flashing and remains orange. 
note
To shut down the projector, 
see page 43. Shutting down 
the projector correctly 
prevents premature lamp 
failure and possible damage 
from overheating.

3. Press the red PPower button on top of the projector—or press 
the P
Power button on the remote control.
(If this is your first time using the remote control, make sure the 
batteries are installed and the power switch on the side of the 
remote is turned on; see page 46.) 
The Ppower light flashes green as the projector warms up, and an 
image begins to appear after about 30 seconds. When the 
Ppower light stops flashing and remains green (in about a 
minute) the projector is ready for use. 
4. If you’ve connected a Windows-based computer to the projector, 
you may see a New Hardware Wizard saying your computer has 
found a plug-and-play monitor; if so, click 
Cancel.

Never look into the lens 
when the lamp is on. This 
can damage your eyes, and is 
especially dangerous for 
children.

Selecting the Image Source
Selecting the image source lets you switch between images input from 
different pieces of equipment connected to the projector (such as a 
computer or DVD player), or turn on EasyMP.net if that option has 
been installed. 
If you don’t see the image you want, select it using the 
Source 
buttons either on the projector or the remote control. 
The 
Source buttons work as follows:
■The projector has two Source buttons. Use the Computer/DVI 
button to switch between equipment connected to the 
Computer 1, Computer 2, and DVI ports (or to select 
EasyMP.net, if that option has been installed). 
Use the 
Video/BNC button to switch between equipment 
connected to the Video, S-Video, and BNC ports. 
■The remote control has seven Source buttons. Use them to 
switch between equipment connected to the port identified on 
each button. 
Note that the Computer 1, Computer 2, and BNC ports can be set up 
to use different input signals (for example, Analog RGB or RGB 
Video)—so if you have equipment connected to one of these ports, it’s 
important to make sure the correct signal is selected to match the 
equipment you’re using. You can select the input signal settings using 
the projector’s menu system; see page 70. 
note
To focus and adjust the 
image, see page 38. If a 
projected image fails to 
appear, see page 35 for help.
note
You can also preview all 
sources on one screen to help 
you select the desired source 
(see page 52).

Troubleshooting Display Problems
Follow these guidelines if you’re having trouble displaying an image.
You Can’t Project an Image
If you see a blank screen or a blue screen with the No Signal message, 
try the following:
■Make sure the cables are connected correctly, as described in 
Chapter 1.

cover is off. 
■If you’ve connected more than one computer and/or video source, 
you may need to press one of the 
Source buttons on the 
projector’s control panel or the remote control to select the 
correct source. (Allow a few seconds for the projector to sync up 
after pressing the button.)
■If you’re using a PC laptop, press the function key on your 
keyboard that lets you display on an external monitor. It may be

Adjusting the Image
Once you see your image, you need to make certain adjustments:    
■To focus or zoom your image, see below. 
■If the image is too high or too low, you can reposition it. See 
page 39.
■If the image isn’t square, see page 40.
■If a computer image displays incorrectly, see page 42. 
If you want to fine-tune the image and/or sound, see Chapter 4.
Focusing and Zooming Your Image
Use the Focus buttons on the remote control (or on the projector) to 
sharpen the image. 
Use the 
Zoom buttons 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 53 for instructions. 
note
The Focus and Zoom 
buttons won’t work when 
the wide-angle rear 
projection lens is installed.

Adjusting the Height of Your Image
If the image is too low on the screen, you can raise it using the Lens 
Shift. This is the best method for adjusting the height of the image. If 
you need to raise the image further, you can tilt the projector upward 
by extending the feet. 
Using the Lens Shift 
To raise or lower the image, use the Lens Shift buttons on the remote 
control (or on the projector). 
Raising the Projector’s Feet
If you need to raise the image further, you can incline the projector:
1. Stand behind the projector. Press the foot release buttons on each 
side and lift the front of the projector. 
note
The Lens Shift buttons 
won’t work when the 
wide-angle rear projection 
lens is installed.

							40Displaying and Adjusting the Image2. Once the image is positioned where you want it, release the 
buttons to lock the feet in position.
3. If necessary, you can level the picture or fine-tune the height by 
turning the projector feet. 
Raising the projector causes the image to distort or “keystone,” but 
you can manually correct the shape as described in the next section.
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 and 
using the Lens Shift (instead of tilting the projector upward) to adjust 
the image height. 
If this isn’t possible, use one of these methods to correct the image 
shape: 
■If the image tapers inward on the right and left sides only, use 
Keystone correction as described below. 
■If the image looks uneven on all sides, you can adjust its shape 
using Quick Corner (see page 41). 
You cannot use both Keystone correction and Quick Corner at the 
same time. 
Using Keystone Correction
To adjust your image when the right and left sides are uneven, do one 
of the following:
■Use the Keystone buttons on the projector’s control panel to 
adjust the image shape. 
Projector foot
note
The image will be slightly 
shorter after adjusting. If it’s 
important to maintain the 
correct aspect ratio, use the 
menu system to perform 
Keystone correction, then 
adjust the Height setting as 
needed (see page 41).
