Shutting Down the Projector
This projector incorporates Instant Off technology. To turn it off, you 
can press its Ppower button as described below, unplug it, or turn off 
a power switch that supplies power to the projector. You don’t have to 
wait for the projector to cool down first.
1. To turn off the projector, press the Ppower
 button on the remote 
control or projector.
You see a confirmation message. 
(If you don’t want to turn it off, 
press any other button.)
2. Press the Ppower button again. The projection lamp turns off 
and the projector beeps twice. You can then unplug the power 
cord. 
If you want to turn the projector on again, make sure the orange 
Ppower light is not flashing, then press the Ppower button.
note
Lamp life will vary 
depending upon mode 
selected, environmental 
conditions, and usage. 
Turn off this product when 
not in use to prolong the life 
of the projector. 
You can set the projector to 
automatically turn off the 
lamp and enter “sleep mode” 
when it has not received any 
signals for 1 to 30 minutes 
(see page 71). 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.

Displaying and Adjusting 
the Image
Follow the guidelines in this chapter for: 
■Selecting an image source
■Adjusting the image 
						

							46Displaying and Adjusting the Image
Selecting an Image Source
You may need to select the image source if you have multiple image 
sources connected to the projector (such as a computer or DVD 
player). Selecting the image source lets you switch between images 
input from different pieces of connected equipment. 
If you don’t see the image you want, press the 
Source Search button 
on the remote control or the projector until you see the image you 
want to project. Or, press one of the Source buttons on the remote 
control (
Computer, Video, or USB).
If you still can’t see an image or can’t project the same image that is on 
your notebook or computer screen, see page 93 for solutions.
Select 
USB to project from a USB device (EX51/EX71 only). See 
page 59 for instructions.
Adjusting the Image
Once you see your image, you may need to make certain adjustments:
■If the image is too high or too low, reposition it as described 
below.
■If the image isn’t square, see page 47.
■To focus or zoom your image, see page 49. 
■To quickly adjust the color, brightness, or contrast, see page 50.
■To change the image aspect ratio, see page 51.
■If you need to fine-tune the image and/or sound, see Chapter 5.

Adjusting the Position of the Image
If the image is too low on the screen, you can use the front adjustable 
foot to raise it. 
1. 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 the image is tilted or you need to fine-tune the height of the 
image, you can turn the projector’s adjustable rear feet.
Raising the projector may cause the image shape to distort or 
“keystone,” but you can correct the shape as described below. 
Adjusting the Image Shape
You can maintain a rectangular image by placing the projector directly 
in front of the screen and keeping it level. This also produces the best 
picture quality. If the projector is tilted up or down (up to 30°), or 
placed at an angle, the shape may “keystone” and you may need to 
correct the image shape. 
						

							48Displaying and Adjusting the ImageThe EX51 and EX71 projectors include an 
Auto Keystone function 
that detects and corrects vertical keystone distortion. It takes about 
one second after the projector starts for the image to be corrected.
If your image is still distorted, or you are using the EX31projector, do 
one of the following:
■Press the appropriate keystone correction button on the 
projector’s control panel until the shape is evenly rectangular.
■Select the Keystone setting in the projector’s Settings menu (see 
page 69). Then use the arrow buttons on the remote control to 
adjust the shape of 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 55 for instructions.
