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 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 44). If you notice 
lines or edges looking jagged after adjusting the shape, decrease 
the Sharpness setting (see page 70). 
■Position (in the Video menu)
If the image is slightly cut off on one or more sides, it may not be 
centered exactly. You can use this setting 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, you should try 
adjusting the Resolution 
setting first (see page 70). 
						

							72Fine-tuning the Projector
Adjusting the Color
The projector provides several ways for you to adjust the color:
■Color Mode button (also in the Video menu) 
Lets you quickly adjust the color and brightness for various 
environments. Use either the remote control or the 
Color Mode 
setting in the Video menu; you can save a different setting for 
each computer and/or video source. Select from these settings:
sRGB: To use the sRGB standard for computer displays (the 
default when projecting from a computer with analog video)
Dynamic: For presentations in bright rooms 
Presentation: For presentations in dark rooms
Theatre: For optimizing movie images with natural color (the 
default for video display)
Living Room: For optimizing video games
■Color (in the Video menu)
Adjusts the color intensity, from black-and-white to full color 
(not available for adjusting computer images).
■Tint (in the Video menu)
Adjusts the balance of magenta to green (not available for 
adjusting computer images or RGB video images).
■Color Adjustment (in the Advanced1 menu)
Adjusts the color temperature. Select Color Temp. to set a 
temperature between 5000 and 10000 °K. Or select 
RGB to 
adjust individual red, green, and blue values, as shown. (Not 
available if 
sRGB is selected as the Color Mode setting.)

Customizing Projector Features
You can use the menu system to change the video signal input at 
certain ports, turn sleep mode on or off, adjust the network settings, 
change the language, and customize several other features.
Image Setup Options
Use these settings to change how the projector processes incoming 
video signals. Several of these settings should normally be left at the 
factory default setting (except for the 
Computer and BNC Input 
settings). 
■Computer Input (in the Setting menu)
Select the setting for the type of equipment you’ve connected to 
the 
Computer port:
Auto: To have the projector automatically detect the signal
RGB: For a video player that outputs an RGB video signal 
Component Video: For a video player that outputs a component 
video signal.
■BNC Input (in the Setting menu)
Select the setting for the type of equipment you’ve connected to 
the BNC ports: 
Auto: To have the projector automatically detect the signal
RGB: For a video player that outputs an RGB video signal
Component Video: For a video player that outputs a component 
video signal
■Video Signal (in the Video menu)
Leave this setting at Auto unless you are using a 60-hertz PAL 
system (select 
PAL60). You can change this setting only if you’re 
displaying an image through the 
Video or S-Video port.  
						

							Fine-tuning the Projector75
■Progressive (in the Advanced1 menu)
This setting should normally be left at its default setting (Video 
or 
Film/Auto). Converts interlaced signals to progressive signals. 
When set to 
OFF, interlaced signals are processed without 
conversion (available for video signals only). 
■BNC Sync Termination (in the Advanced2 menu)
This setting should normally be left Off (for TTL input). If an 
analog (75-ohm) terminator is required, as for a switcher, change 
the setting to 
ON. 
Communication Setup Options
These options let you set up the projector so it can be monitored and 
controlled from a remote computer (see Chapter 5). 
■Standby Mode (in the Advanced1 menu)
Select Network ON to enable the projector to be monitored over 
a network when it’s in standby mode; this setting also lets you 
view images on an external monitor during standby, if the 
monitor has been connected to the projector’s 
Monitor Out port. 
■Network (in the Advanced2 menu)
Used for managing the projector over a network (see Chapter 5). 
If the network assigns addresses automatically, turn on 
DHCP. 
Otherwise, turn off 
DHCP and enter the projector’s IP Address, 
Subnet Mask, and Gateway Address, if applicable. 
If you want to monitor the projector using a network 
management utility, select 
SNMP and enter at least one trap IP 
address. 
■COM Port (in the Advanced2 menu)
Used for communicating with a computer running the EMP 
Link21L utility software. (You can download this utility free of 
charge from http://support.epson.com.) Select 
RS-232C or USB, 
depending on the port that’s being used for communication with 
the computer. Turn off the projector and then turn it back on for 
the new setting to take effect.

Miscellaneous Setup Options
■No-Signal Msg. (in the Setting menu) 
Selects a screen color or image to display when the projector is 
not receiving a signal. The logo setting displays an image that 
you previously transferred to the projector (see page 78).
■Sleep mode (in the Setting menu)
When sleep mode is on, the projector turns off the lamp if it 
has not received any input signals for 30 minutes. Turn sleep 
mode off if you want the lamp to remain on all the time (this 
is the default setting).
■Message (in the Setting menu)
Selects whether the image source or the color mode is 
displayed on the screen.
■Rear Proj. (in the Advanced1 menu)
Turn on to project from behind onto a transparent screen.
■Ceiling (in the Advanced1 menu)
Turn on when the projector is mounted upside-down from 
the ceiling.
■Language (in the Advanced1 menu)
Select from nine languages to be used for the projector 
menus.
■Direct Power ON (in the Advanced2 menu)
When this option is enabled, projection starts as soon as you 
plug in the power cord. You don’t need to press the 
P
Power button.
note
When Direct Power ON 
is enabled, turn off your 
projector as you normally 
would; see page 49 for 
details. 
						

							Fine-tuning the Projector77
Using the Projector’s Security Features
To prevent unauthorized use of the projector, you can do the 
following:
■Create an identifying user logo that is displayed at startup and/or 
when the 
A/V Mute button is pressed
■Assign a password; this can be disabled for a set period if you want 
to loan the projector to someone
■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
If you create a user’s logo for the projector, you can lock the logo on 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. 
If you assign the projector a password, a screen appears requesting the 
password whenever the projector is turned on. If you enter the 
password incorrectly three times in succession, the projector’s 
operation is locked and you’ll need to disconnect the power cord, then 
reconnect it to redisplay the password screen. If you enter the 
incorrect password 30 times in succession, the projector is locked and 
you’ll need to contact Epson to unlock it. See “Where To Get Help” 
on page 121.
If someone else will be using the projector for awhile but you want to 
make sure that person returns it by a certain time, you can temporarily 
disable the password for a set period. When that time has elapsed, the 
password is reactivated and must be entered before the projector can 
be used.
When you enable the Operation Lock feature, all of the projector’s 
buttons are disabled except the P
 Power button.
note
If you enable the password 
before you set one and you 
see the prompt to enter the 
password, enter the default 
password 0000 to proceed.

Creating Your Own Screen Logo
You can transfer any image on your computer to the projector, and 
then use it as the startup screen and/or the screen that is displayed 
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. The 
projector considers this image the “User’s Logo.”
