RGB to 
adjust individual red, green, and blue values. (Not available if 
sRGB is selected as the Color Mode setting.)
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 changing the position of the projected 
image, you can correct tracking and sync for computer images, or 
change the aspect ratio to widescreen format for video images. 
1. Press the 
Menu button and select the Signal menu. 
You see a screen similar to one of those below. (The settings will 
be different depending on the source you are projecting from.)
note
The Brightness setting 
changes the opacity of the 
projector’s LCD panels. You 
can also change the lamp’s 
brightness. Select 
Brightness Control in the 
Setting menu, then choose 
High or Low (the default 
setting is High).
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 26 for 
details.

							112Fine-Tuning the Projector2. Use the  pointer button to highlight the desired option, then 
adjust it as needed:
■Auto Setup 
Leave this setting 
ON to automatically optimize the computer 
image. Turn it off if you want to save adjustments you have 
made to the video settings.
■Tracking 
Adjust this value to eliminate vertical stripes in the image.
■Sync
Adjust this value if the image appears blurry or flickers.
■Position
If the image is slightly cut off on one or more sides, it may not 
be centered exactly. Select this setting and use the  pointer 
button to center it.
■Computer Input
If the colors don’t look right on the Auto setting, select the 
setting for the type of equipment you’ve connected to the 
Computer/Component Video port:
RGB: For a computer connection.
Component Video: For a video player that outputs a 
component video signal. 
■Video Signal 
Leave this setting at 
Auto unless you are using a 60-Hz PAL 
system (then select 
PAL60).
tip
Before adjusting tracking or 
sync, fill the screen with an 
image containing fine 
detail. For example, in 
Windows you can select a 
pattern to appear as your 
desktop background. If this 
option isn’t available, try 
projecting black text on a 
white background.

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 
Squares up the shape of the image after the projector has been 
tilted upward. If you notice lines or edges looking jagged after 
adjusting the shape, decrease the Sharpness setting (see page 110). 
■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 (and enabled by default).
■Operation Lock
Lets you disable all of the buttons on the projector except the 
Power button. See page 119 for more information.
■Pointer Shape
Lets you choose from three alternative pointer shapes. See page 36 
for more information.
■Brightness Control
Lets you select from two levels of brightness. The Low setting 
reduces power consumption and noise, and extends the lamp’s 
operating life.

■Volume
Raises or lowers the volume of the projector’s speaker.
■EasyMP Audio Out
Lets you output sound from EasyMP scenarios (.wav files) or 
MPEG files to external speakers with built-in amplifiers. Connect 
the speakers as shown on page 48.
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. See page 117.
■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 119. 
If you create a user’s logo for the projector, you can set up the logo so 
it is displayed as the startup screen and/or AV/Mute screen. 
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. 
Enabling Password Protection
To prevent unauthorized use, you can assign the projector a password. 
If you do, a screen will appear requesting the password whenever the 
projector is plugged in and turned on. If an incorrect password is 
entered three times in succession, the projector’s operation is locked 
and the power cord must be disconnected and reinserted to redisplay 
the password screen. If an incorrect password is entered thirty times in 
succession, the user must contact Epson to unlock the projector. 
note
You can also adjust the 
volume using the remote 
control.
note
It’s a good idea to write 
down your password. 
If you leave the projector 
plugged in, the Password 
Protect Release screen will 
not appear. You only need a 
password if you unplug and 
reconnect the power cable.

setting is 0000.) 
7. When you see a confirmation message, reenter the password. 
Then press the 
Menu button to exit the screen.
8. Press the 
Num button on the remote control to deactivate the

numeric keypad to enter the number of hours (from 0 to 9999) 
that you want the password feature disabled. If you want the 
projector to request the password every time it is turned on, set 
the timer to 
0H. 
caution
If you lose the remote 
control, you will not be able 
to enter the password. Keep 
the remote control in a safe 
place at all times.

Logo as the Background Color 
in the Extended menu). None of the User’s Logo features in the 
Extended menu can be changed when the User’s Logo Protect 
function is enabled.
Starting the Projector with a Password
When the password function is enabled, you see this screen when you 
plug in and turn on the projector:
Hold down the 
Num button on the remote control and use the 
numeric keypad to enter the four digit password.
The password screen closes, the numeric keypad is automatically 
deactivated, and projection begins.
If the password is not correct, you see the message 
Wrong password. 
Please try again.
 If you enter an incorrect password three times in 
succession, you see the message 
The projector’s operation will be 
locked. Request code xxxxx
 and the projector switches to standby 
mode for approximately 5 minutes. Write down the request code. 
Then disconnect the projector’s power cord from the electrical outlet, 
reconnect it, and turn the projector back on.

							Fine-Tuning the Projector117
When you see the Password Protect Release screen again, you can try 
to enter the correct password.
If you enter an incorrect password 30 times in succession, the 
projector remains locked and you must contact Epson to unlock it. 
If you have forgotten the password, contact Epson with the request 
code number that appears in the Password Protect Release screen for 
assistance. See “Where To Get Help” on page 166.
Creating Your Own Startup Screen
You can transfer any image from your computer or video source to the 
projector and then use it as your startup screen. You can also use it as 
the screen displayed when the projector is not receiving a signal or 
when you press the 
A/V Mute button. The image can be a company 
logo, slogan, photograph, or any other image you want to use. 
Capturing the Image
Start by displaying the image you want to use from either a computer 
or video source, such as a DVD player or digital camera. Then follow 
these steps to capture the image and transfer it to the projector: 
1. Press the 
Menu button on the remote control, highlight the 
Extended menu, and press Enter.
2. Highlight 
User’s Logo and press Enter.
