Adjusting Signal Settings 
Although the projector normally detects and optimizes the input 
signal automatically, you can use the Signal menu to make manual 
adjustments. In addition to chan ging the position of the projected 
image, you can correct tracking and sync for computer images, or 
change the aspect ratio to wide screen format for video images. 
1. Press the 
Menu button, select the Signal menu, and press Enter. 
You see a screen similar to one of those below. (The settings will 
be different depending on the source you are projecting from.)
2. Use the  pointer buttons to highlight the desired option, then  adjust it as needed:
■Auto Setup 
Leave this setting on to automatically optimize the image 
when 
Computer is selected as the source. Turn it off if you 
want to save adjustments you have made to the video settings.
■Resolution
When set to Auto, the resolution (size) of a computer image 
is automatically detected so it can be scaled to fit in the 
projection area. If the image doesn’t display properly after 
you adjust the aspect ratio setting (see page 36), select 
Wide 
to project from a computer with a wide-panel display, or 
Normal for a computer with a 4:3 or 5:4 display.
■Tracking 
Adjust this value to eliminate vertical stripes in the image.
■Sync
Adjust this value if the image appears blurry or flickers.
note
You can also use the remote 
control’s Auto button to 
automatically reset the 
projector’s tracking, sync, 
resolution, and position 
settings. See page 30 for 
details.

Customizing Projector Features
You can use the Settings menu to lock the buttons on the projector, 
adjust audio volume, and customize several other features.
■Keystone

tilted upward. If you notice lines or edges looking jagged after 
adjusting the shape, decrease the Sharpness setting (see page 104). 
■Auto Keystone
Automatically compensates for keystone distortion when the 
projector is tilted upward. This feature is available only when the 
projector is set for front projection (it is enabled by default).
■Control Panel Lock
Lets you disable the buttons on the projector. See page 115 for 
more information.
■Pointer Shape
Lets you choose from three alternative pointer shapes. See page 42 
for more information.
■Power Consumption
Lets you select from two levels of brightness. The ECO setting 
reduces power consumption and  noise, and extends the lamp’s 
operating life.

Using the Projector Security Features
To prevent unauthorized use of the projector, you can do the 
following:
■Assign a password; this can be disabled for a set period if you want 
to loan the projector to someone. 
■Create an identifying user logo that is displayed at startup and/or 
when the 
A/V Mute button is pressed. Unauthorized users cannot 
turn it off or change it. This feature is intended to discourage theft 
and provides a way to identify the projector should it be stolen. 
See page 114.
■Disable the projector’s buttons; this is useful, for example, if 
you’re projecting in a classroom and you want to ensure that no 
one touches the projector’s buttons while you’re using the remote 
control. See page 115. 
■Lock the network configuration settings. See page 112.
