Features of the Projector
Image appearance can be selected to match the
projection environment (Color Mode)
The optimum images for the location can be projected simply by selecting the desired colour mode from the
following seven preset modes.
If "Natural", "Theatre", "Theatre Black 1", "Theatre Black 2" or "sRGB " is selected, the Epson Cinema
Filter effect is applied automatically to increase the contrast and to make skin tones appear with more natural
tints. p.18

Sophisticated colour adjustment
In addition to the "Color Mode", the absolute colour temperature and skin tones can be adjusted by simple
procedures to render the picture even more to your own liking. Further, you can adjust gamma, the offset and
gain for RGB colours, and the hue and saturation of RGBCMY colours, to create colours that match the image.
p.20
Equipped with a wideangle lens shift function
The lens shift function allows the position of the
projected images to be adjusted vertically and
horizontally without distorting the images.
This can allow the projector to be set up with greater
freedom, even if it is suspended from a ceiling or at
an angle to the screen. p.16
Features of the Projector
Equipped with 1.5x short
throw zoom lens
For zoom adjustment, 1.5x short throw zoom lens is provided.
Images can be projected onto an 100" screen (16:9 screen
only) even at a distance of approximately 3 m (10 ft.). p.10
Advanced image quality adjustment functions
Advanced image quality adjustment functions such as "Auto Iris" and "Sharpness (Advanced)" can be used to
enjoy even sharper images. With the Auto Iris function turned on, the amount of light can be automatically
adjusted to match the images being projected, to create images with depth and perspective. The Sharpness function
is used to adjust not only the entire image, but also to emphasize specific regions, such as hair and clothing.
p.23
A variety of image setting functions
Some of the other many functions that are available are as follows.
EPSON Super White is used to prevent overexposure that can result in images that are too bright. p.30
A progressive conversion that lets you obtain ideal results both for images with large amounts of movement
and for still images. p.30
An aspect function that allows images to be viewed in wide-screen format. p.18
Memory functions that allow adjustment results to be stored and later retrieved easily using the remote control.
p.24
Lock settings that can be used to lock the projector's control panel after adjustments have been made so that
they cannot be changed by mistake, or to prevent children from accidentally turning on the power and looking
into the lens. p.31

Lens shift adjustment
The lens shift dials can be used to position the image and is especially useful when using the projector in the
following locations. p.16
Hanging from the ceiling
A screen in a high location
Projector situated to the side so that the screen can be viewed sitting right in front of it
Projector situated on a shelf, etc.
When positioning an image using the lens shift dial, hardly any deterioration of the image occurs because the lens
shift correction is adjusted optically. However, for optimal image quality the lens shift function should not be used.

Avoid setting the projector up in a place which is very dusty or humid, or where there will
be cigarette or other smoke, especially oily smoke.
TIP
Clean the air filter at least once every 3 months.
Clean the air filter more frequently if using the projector in a dusty environment.
When installing against a wall, leave a space of 20 cm (7.9 in.) or more between the
projector and the wall.
A special method of installation is required in order to suspend the projector from the
ceiling. Please contact your dealer if you would like to use this installation method.

Connecting Image Sources
• Turn the power off for both the projector and the signal source before connecting them.
If the power for either device is on at the time of connection, damage may result.
• Check the shapes of the cable connectors and the device ports before making the
connections. If you try to force a connector to fit a device port with a different shape or
number of terminals, a malfunction or damage to the connector or port may result.

to "SCART". "Selecting the image source" p.15
*2 Some regions may not have the D4 SCART adapter included as an accessory.
• Some signal sources may have specially-shaped ports. In such cases, use the
accessory or optional cables that are supplied with the signal source to make the
TIP
connections.
• The cable that should be used to connect video equipment to the projector will depend
on the type of video signal that the equipment outputs. Some kinds of video equipment
output several different types of video signal. The image quality ranking of the video
signal types is generally held to be as follows, in descending order of quality:
Digital component video
S-Video
[S-Video] > Composite video [Video]
[HDMI ] > Analog component video [D4] [InputA] >
You should refer to the documentation provided with the video equipment being used to
check what types of video signal formats the equipment can output. The composite
video format is sometimes simply called "video output".
Preparing the Remote Control
Inserting batteries into the remote control
The remote control is not supplied with batteries already inserted. Insert the accessory batteries
before using the remote control.
Remove the battery cover.
While pressing the knob, lift up.
Insert the batteries.
Check the (+) and (-)
indications inside the
battery compartment and
insert the batteries so that
they face correctly.
If delays in the responsiveness of the remote control occur or if it does not operate
after it has been used for some time, it probably means that the batteries are
TIP
becoming flat. If this happens, replace the batteries with two new batteries. Use two
new AA batteries as replacement batteries.
Install the battery cover.
Insert the tab.
Press down until the battery
cover clicks into place.

Turning the power on and projecting
images
If there is a problem with projection even though the projector is set up and connected correctly,
refer to p.15, 35.
If you set the "Direct Power On" to "On", the power of the unit will turn ON when
the main power switch is turned ON, without having to press the power button of
TIP
the remote control or the projector's control panel.
The projector is equipped with a "Child Lock" function that prevents young
children from accidentally turning the power on and looking into the lens, and
also an "Operation Lock" function that prevents mis-operations. p.31
When using above an altitude of about 1500 m, make sure you set the "High
Altitude Mode" to "On". p.32
This projector is equipped with an automatic
adjustment function that automatically optimizes it
when a computer input signal is switched.
If a laptop computer or a computer with a LCD
screen has been connected to the projector, you
may need to use keyboard or function settings to
change the output destination. While holding down
the key, press (the key with a symbol such
as / on it). After the selection is made,
projection will soon start.

image to these vertical and horizontal limits
simultaneously.
Ex) When the image is shifted horizontally
by the full amount, it cannot be shifted
vertically.
And when the image is shifted
vertically by the full amount, it cannot
be shifted horizontally by more than
11% of its width.
