Locking the Projector
The projector includes two lock settings to prevent the image from being accidentally 
changed once it’s adjusted, and to keep children from turning on the projector without adult 
supervision. 
To access the lock settings, follow these steps:
1. Press the 
Menu button on the remote control.
2. Use the menu navigation buttons to open the 
Settings 
menu, then open the Operation menu.
3. Choose from these options:
■Child Lock to disable the PPower button on the 
projector’s control panel unless it is pressed for 
about 3 seconds. (You can use the P
Power 
button to turn it off, however.) Since you can still 
use the remote control to turn on the projector, 
you may want to keep it away from children’s reach.
■Operation Lock to disable all the buttons on the projector’s control panel. A lock 
icon appears on the screen whenever you press a button with Operation Lock turned 
on. To operate the projector, you must use the remote control. To cancel Operation 
Lock, press and hold the
 Select button on the projector’s control panel for at least 
7 seconds.
4. Press 
Menu to exit the menu system. 
If you turned on the Operation Lock, the projector buttons are now locked.
If you turned on the Child Lock, turn off the projector and let it cool down. The Child 
Lock takes effect after the cool-down period.

Making Detailed Adjustments
You can use the projector’s on-screen menus to make detailed adjustments to the image 
quality—such as the brightness, contrast, sharpness, and color. You can also change the menu 
display, sleep mode settings, and other projector features. 
Using the Menu System
You can access the menu system either from the remote control or the buttons on the 
projector’s control panel. You can access the full menu or a line menu that lets you adjust the 
Picture and Memory settings while viewing their effects on your display. You can also change 
the menu language and control how the menus display (see page 34). 
1. To display the full menu, press the 
Menu button on the projector or remote control. You 
see a display like this one (the actual display depends on the connected equipment):
Note: If no equipment is connected to the projector, some options may not be available.
2. Press the u or d button to highlight an option, then press the Select button to select 
it.
3. Press the u, d, l, or r button to change settings as necessary. You may have to press the 
Select button to confirm your choice.
4. When you’re finished, press the 
Esc button to return to the previous menu or press the 
Menu button to exit the menu system.

Adjusting the Picture Quality
Before fine-tuning the image using these adjustments, make sure you have already selected the 
best Color Mode for your picture and viewing environment, as described on page 28. Then 
use the settings in this section to finish adjusting the picture to your liking. 
Most image quality settings are saved independently for each input source (Video, S-Video, 
HDMI, Input A, Input B) and color mode. After you finish adjusting the settings for one 
input source, switch to the other input sources you’ll be using and make any necessary 
adjustments.
Input Brightness Settings
If the signal from connected equipment is weak and images appear dark, you can adjust the 
White Level/Black Level or the Brightness/Contrast. You can adjust either one of these 
settings (but not both) for each image source and color mode. 
Adjust this setting first, then fine-tune the image with the remaining settings.
The Brightness setting controls how much light is produced by the projector, and the 
Contrast setting adjusts the difference between the bright and dark areas of the projected 
image. The other settings listed on the following page control how the projector interprets the 
light and dark areas of the picture.

■Brightness/Contrast
Note: If you cannot access the Brightness and Contrast settings, highlight Input Adjustment 
and press the Select button, then choose Brightness/Contrast in the sub-menu.
Adjust the brightness so it’s suitable for your viewing conditions. For example, if you’re 
projecting in a brightly lit room or onto an especially large screen, you may need to 
increase the brightness. Decrease the brightness for dark rooms or small screens; this also 
reduces power consumption and fan noise, and helps to prolong the life of the lamp. 
■White Level/Black Level
Note: If you cannot access the White Level and Black Level settings, highlight Input 
Adjustment and press the Select button, then choose White Level/Black Level in the 
sub-menu.
Adjust the White Level so that details in the brightest parts of the image are not washed 
out. Then adjust the Black Level so that shadow-level details are still visible in the darkest 
parts of the image.
■Auto Iris
When this setting is on, the amount of light produced by the lamp is automatically 
adjusted according to the brightness of the image. The setting is stored separately for each 
image source and color mode.
■Setup Level
This setting adjusts the threshold at which dark areas of the image are rendered black 
(0 IRE). For compatibility with most DVD and video equipment sold in the United 
States, leave this setting at 0%. Check your video equipment’s specifications to be sure of 
the correct setting. 
■EPSON Super White
Note: This setting can be used only when the Color Mode is set to Natural, Theatre, or Theatre 
Black 1 or 2 (see page 28).
If bright parts of the image are washed out or overexposed (when the input signal 
contains values over 100 IRE), turn this setting on to compensate. When this setting is 
turned on, the projector disregards the DVI-Video Level setting.

■DVI-Video Level
Note: This setting can be used only when HDMI is selected as the image source (see page 22).
If your video equipment has a DVI port and you’ve connected it to the projector using an 
HDMI/DVI cable, set the level of the projector to match that of the video equipment. 
When this setting is turned on, the projector disregards the EPSON Super White setting.
Sharpness and Picture Quality Settings
If the image looks fuzzy, or if it contains noise or flickering, you can use these settings to 
correct it.
■Sharpness
Use this function to make lines and edges appear more distinct in the image. This setting 
is stored separately for each image source and color mode setting. You can select 
Standard to adjust the sharpness of the entire image, or select Advanced to access the 
following submenu:
Choose 
High-band Enhancement to sharpen details such as hair and clothing. Choose 
Low-band Enhancement to sharpen large contours and backgrounds. 
■Progressive
The projector uses 3D DigiScan HD Circuitry Processing for video-sourced images. For 
film-sourced images, the projector uses 3-2 pulldown detection and optimizes the image 
accordingly. 
Leave this setting on 
Video for most purposes. Set to Film when the input source is a 
film, and you want to project an image closer to its original source. 
Note: This setting applies only when viewing composite video, S-video, component video, or 
525i or 625i RGB video (see page 63).

Color Settings
If the image colors don’t look correct, you can adjust them using these settings. Use the first 
three settings described below to make the most visible changes. If you only need to make 
slight adjustments, you can fine-tune the picture with the remaining settings. Most color 
settings are stored separately for each image source and color mode.
■Color Saturation
Adjusts the color intensity of the image. 
■Tint
Shifts the color balance between magenta and green. 
■Abs. Color Temp.
Shifts the color balance between red and blue, making the image appear warmer or 
cooler. You can also access this setting by pressing the 
ColorTemp. button on the remote 
control. See page 29 for more information.
Note: You can display a test pattern to help adjust the color temperature. See page 34 for more 
information.
■Skin Tone
Makes fine adjustments to the tint. Controls the amount of magenta or green in the 
image. Also useful for correcting black-and-white images, if they look tinted. You can also 
access this setting by pressing the 
S. Tone button on the remote control. See page 29 for 
more information.

■RGB
Note: If you cannot access the RGB settings, highlight RGB/RGBCMY (the first item in the 
menu list) and press the Select button, then choose RGB in the sub-menu.
Use the RGB settings to fine-tune the color of the image. You can adjust the offset and 
gain for each signal color (red, green, and blue). Use 
Offset to adjust darker shades and 
Gain for the lightest shades. 
■RGBCMY
Note: If you cannot access the RGBCMY settings, highlight RGB/RGBCMY (the first item in 
the menu list) and press the Select button, then choose RGBCMY in the sub-menu.
Use the RGBCMY settings to adjust the hue and saturation of the six color components 
(red, green, blue, cyan, magenta, yellow). After adjusting each color, press 
Esc or select 
Return to move to another menu option. 
■Gamma
You can select from 5 gamma settings (2.0 to 2.4) or customize your own setting from 
your image or a displayed graph. Lower values will increase the contrast of dark areas, but 
tend to blur the bright areas. Higher values will darken the light areas.
You can also access this setting by pressing the 
Gamma button on the remote control. 
See page 30 for more information.

Adjustments Just for Computer Images
In addition to the settings described above, you can adjust the Tracking and Sync settings for 
analog RGB computer images. Normally, these settings are adjusted automatically by the 
projector. If you notice that the image is blurry or contains dark vertical bands, you may need 
to adjust the settings yourself.
■Auto Setup
Leave this setting on so that the projector automatically adjusts the tracking, sync, and 
position of the image.
■Tracking
Adjust the tracking to eliminate vertical bands. It is easiest to 
adjust the tracking when the image contains a lot of fine detail 
(such as black text on a white background).
■Sync.
Adjust the synchronization to eliminate blurriness. For best results, 
make sure the tracking is properly adjusted first.
