Adjusts the difference between light and dark areas. 
■Sharpness
Adjusts the sharpness of the image.
■Color Adjustment
Adjusts the tint of the image (not available for RGB video 
images). 
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 on the remote control and select the 
Signal menu. 
You see a screen similar to the one 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 28 for 
details.

							64Fine-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.
■Resolution
If your image is distorted (compressed, stretched, partially cut 
off, or doesn’t completely fill the display area), the projector’s 
resolution setting may not match that of your computer. 
Select 
Auto to let the projector adjust the resolution 
automatically, or 
Manual to adjust the setting yourself. (Press 
Enter after you make the selection.)
■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.
■Preset
Once you’ve fine-tuned the settings in the Signal menu for 
the computer you’re using, you can save them as a group 
using one of the ten 
Preset settings. The next time you use 
the same computer, simply press the 
Preset button on the 
remote control to recall your saved settings. (Press the 
Preset 
button repeatedly to select the number corresponding to the 
setting you want to use.)

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.

							Fine-Tuning the Projector65 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 (select 
PAL60).
Adjusting the Image Size, Shape, and 
Position
Whether you’re projecting from a computer or video player, you can 
use these settings to adjust the size, shape, and position of the image.
■Resize button
Adjusts how an image fits into the display area. 
For computer images, resizing is normally unnecessary, since the 
projector automatically resizes the image to make the best use of 
the display area. If you press the 
Resize button on the projector 
or remote control, the projector displays the image at the output 
resolution of the computer (which makes the image larger or 
smaller, depending on its resolution). If the resolution of the 
image is the same as the projector’s (1024 
× 768), pressing Resize 
has no effect. 
For video images, pressing 
Resize switches the aspect ratio 
between 4:3 and 16:9. This lets you play certain digital video 
images or movies recorded on certain DVDs in 16:9 widescreen 
format. 
■Keystone (in the Setting menu)
Squares up the shape of the image after the projector has been 
tilted upward or angled to one side (see page 26). If you notice 
lines or edges looking jagged after adjusting the shape, decrease 
the Sharpness setting (see page 62). 
■Position (in the Signal menu)
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 (not available for digital RGB or RGB video images). 
note
If your computer image is 
stretched, compressed, or 
doesn’t fit correctly on the 
screen, try adjusting the 
Resolution setting first (see 
page 64).

Adjusting the Color
The projector provides several ways for you to adjust the color:
■Color Mode button (also in the Image menu) 
Lets you quickly adjust the color and brightness for various 
environments. Use either the remote control or the 
Color Mode 
setting in the Image menu. You can save a different setting for 
each computer and/or video source. Select from these settings:
■Dynamic: For projecting movies or playing video games in 
vivid color in a bright room.
■Presentation: For presentations in dark rooms.
■Theatre: For optimizing movie images with natural color in a 
dark room (the default for video or S-Video display). 
■Living Room: For playing video games and watching TV in 
a bright room.
■sRGB: For standard sRGB computer displays (the default 
when projecting from a computer with analog video).
■Color Adjustment (in the Setting menu)

Color Temp. to set a 
temperature between 5000 and 10000 °K. Or select 
RGB to 
adjust individual red, green, and blue values. (Not available if 
sRGB is selected as the Color Mode setting.)

to loan the projector to someone. See page 68.
■Create an identifying user logo that is displayed at startup and/or 
when the 
A/V Mute button is pressed. See page 71.
■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 72. 
note
You can also adjust the 
volume using the remote 
control.

							68Fine-Tuning the ProjectorIf 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. 
The default setting for the Password Protect function is 
OFF. Follow 
these steps to turn password protection on:
1. Press the 
Freeze button on the remote control for about five 
seconds.
You see this screen:
2. Use the   pointer button to set Power ON Protect to 
ON. Then 
press 
Enter.
3. Select 
Password and press Enter.
4. When you see a message asking if you want to change the 
password, select 
Yes and press Enter.
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.
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.

0H. 
The countdown for the elapsed time begins as soon as you close 
the Password Protect menu. (You can check the elapsed time in 
this menu next to 
Time elapsed.)
10. To enable your screen logo, select 
User’s Logo Protect and press 
Enter. Select ON and press Enter. 
When this feature is on, the logo appears whenever you turn on 
the projector (if the 
Startup Screen is enabled in the Extended 
menu; see page 71). It also appears when you press the A/V Mute 
button (if you selected the 
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.

plug in and turn on the projector:
1. Press the 
Num button on the remote control to activate the 
numeric keypad.
2. 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

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. 
When you see the Password Protect Release screen again, you can try 
to enter the correct password.
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 112.
If you enter an incorrect password 30 times in succession, the 
projector remains locked and you must contact Epson to unlock it.
