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

sRGB

Theatre Black1

Theatre Black2

Dynamic

Living Room

Mode

Theatre

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

Features of the Projector

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

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.

Lock settings that can be used to lock the projector's control panel after adjustments have been made so that

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

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.

*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

connections.

TIP • 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".

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.

Install the battery cover.

Insert the tab.

Press down until the battery cover clicks into place.

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.

If there is a problem with projection even though the projector is set up and connected correctly, refer to p.15, 35.

TIP

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 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.
