Adjusting Signal Settings 
Although the projector normally detects and optimizes the input

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.

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 23 for 
details. 
						

							48Fine-Tuning the ProjectorYou see a screen similar to one of those below. (The settings will

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.
■Progressive
Turn this setting On to convert composite video signals into 
progressive signals (best for still images). Leave the setting 
Off 
for moving images.
■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:

component video signal.

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.

■Video Signal 
Leave this setting at 
Auto unless you are using a 60-Hz PAL 
system (then select 
PAL60).
■Resize
Choose an aspect ratio of either 4:3 or 16:9. Normal is the 
default setting for a computer connection. 
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 46). 
■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).
■Operation Lock
Lets you disable all of the buttons on the projector except the 
P
Power button. See page 55 for more information.
■Pointer Shape
Lets you choose from three alternative pointer shapes. See page 32 
for more information. 
						

							50Fine-Tuning the Projector
■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.
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 53.
■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 55. 
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.
Network Protect is not 
available for the 
1700c/1710c projector.
