    Adjusting the Image Quality
    You can use the Video menu to adjust the brightness, sharpness, color, 
    tint, and contrast. If you’re projecting from a computer, there are 
    additional adjustments you can make (see page 63).
    Adjusting the Image
    1. Press the Menu button on the remote control and select the 
    Image menu. You see the Image menu screen. 
    2. Use the  pointer button to highlight the desired option, then 
    adjust it as needed:
    ■Color Mode
    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.

    							Fine-Tuning the Projector63 sRGB:
     For standard sRGB computer displays (the default 
    when projecting from a computer with analog video).
    ■Brightness 
    Lightens or darkens the overall image.
    ■Contrast
    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.) 
    ■Computer 1 Input/Computer 2 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 port(s):
    RGB: For a computer connection.
    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).

    							66Fine-Tuning the Projector
    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)
    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. (Not available if 
    sRGB is selected as the Color Mode setting.)

    1. Press the 
    Menu button on the remote control and select the 
    Setting menu. 
    2. Choose

    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. 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.

    5. Press the Num button on the remote control. When it lights, the 
    numeric keypad is activated.
    6. Use the numeric keypad to enter a four digit password. (The 
    default 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.
    9. If you want to disable the password temporarily, select 
    Timer and 
    press 
    Enter. Then hold down the Num button while you use 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. 
    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.

    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:
    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

    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. 
    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.
