Features of the Projector
Image appearance can be selected to match the
projection environment (Color Mode)
Sophisticated colour adjustment
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
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.

Features of the Projector
Equipped with a wide-
angle 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
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 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
Advanced image quality adjustment 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
Equipped with 1.5x short

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.
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
While referring to the table below, position the projector so that the images are projected onto the
screen at the optimum size.
The values should be used as a guide for setting up the projector.
Be sure to read the separate

Connecting Image Sources
*1 If a DVD has been connected using a D4 SCART adapter, change the "D4/SCART" setting in the "Input Signal"
to "SCART". "Selecting the image source" p.15
*2 Some regions may not have the D4 SCART adapter included as an accessory.
•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.
•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
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 [HDMI ] > Analog component video [D4] [InputA] >
S-Video [S-Video] > Composite video [Video]
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".
