Attention
• Power off the equipment before connecting. Connecting while it is powered
on may cause malfunctions to occur.
• When connecting, check the cable's connector shape with the shape of the
port. Inserting a connector with a different orientation or shape by force
may cause malfunctions to occur or may damage the equipment.
q
•Use an HDMI cable that conforms to HDMI standard.
•Depending on the equipment you are connecting to, the
connecter shape may be specific to that equipment. In such a
case, use the cable that was supplied with the equipment or is
available as an optional accessory for that equipment.
•The cable used to connect to the projector will vary according to
the video signal output from the video equipment. Some video
equipment can output several different types of video signals. In
general, the following are video signals in the order of image
quality, from best quality to lesser quality.
Component video > S-video > Composite video
Check your video equipment's documentation to see which video
signals it can output. Composite video may also be simply called
"Video out".

Useful Functions
This chapter explains useful tips for projection, and the Security functions.

You can change the projected image in the following two ways.
•Changing by Source Search
The projector automatically detects signals being input from connected
equipment, and the image being input from the equipment is projected.
•Changing directly to the target image
You can use the Remote Control buttons to change to the target
input port.
Automatically Detect Input Signal and Change
the Projected Image (Source Search)
You can project the target image quickly as input ports with no image
signal being input are ignored when you change by pressing the [Source
Search] button.
AComputer
BS-Video
CVideo
DHDMI
EUSB
Procedure
When your video equipment is connected, start playback before
beginning this operation.
Using the Remote Control Using the Control panel
When two or more pieces of equipment are connected, press the
[Source Search] button until the target image is projected.
q
The following screen showing the status of image signals is
displayed when only the image that the projector is currently
displaying is available, or when no image signal can be found. You
can select the input port where the equipment you want to use is
connected. If no operation is performed after about 10 seconds, the
screen closes.

Selecting the Projection Quality (Selecting Color
Mode)
You can easily obtain the optimum image quality simply by selecting
the setting that best corresponds to your surroundings when projecting.
The brightness of the image varies depending on the mode selected.
Mode Application
Dynamic Ideal for use in a bright room.
Living Room Ideal for using the projector in a room with closed
curtains.
Theatre Ideal for watching films in a dark room. Gives images
a natural tone.
Game Ideal for playing games that involve speed in a bright
room.
Procedure
Remote Control
Each time you press the button, the Color Mode name is displayed on
the screen and the Color Mode changes.
If you press the button while the Color Mode name is displayed on the
screen, it changes to the next Color Mode.
q
The color mode can also be set using Color Mode in the Image
menu from the Configuration Menu.sp.31
Functions for Enhancing Projection

Setting the Auto Iris
By automatically setting the luminance according to the brightness of
the displayed image, it lets you enjoy deep and rich images.
Procedure
A
Press the [Menu] button and select Image - Auto Iris from
the Configuration Menu.s"Using the Configuration Menu"
p.30
Using the Remote Control Using the Control panel
B Select On.
The setting is stored for each Color Mode.
C
Press the [Menu] button to close the Configuration Menu.
Hiding the Image and Sound Temporarily (A/V
Mute)
Use this to temporarily turn off the screen image.
Procedure
Remote Control Body
Each time you press the button, or open/close the lens cover A/V Mute
turns on or off.
q
•If you use this function when projecting moving images, the
images and sound continue to be played back by the source, and
you cannot return to the point where A/V Mute was activated.
•When activated from the remote control, you can choose to
display Black, Blue, or Logo as the A/V Mute display using the
Extended - Display - A/V Mute setting from the Configuration
menu.sp.35
•When the A/V mute slide is closed for approximately 30
minutes, Lens Cover Timer activates and the power is
automatically turned off. If you do not want Lens Cover Timer
to activate, change the Lens Cover Timer setting to Off from
Operation in the Extended menu.sp.35

16

Freezing the Image (Freeze)
When Freeze is activated on moving images, the frozen image continues
to project on the screen, so you can project a moving image one frame
at a time like a still photo. Also, you can perform operations such as
changing between files during presentations from a computer without
projecting any images if the Freeze function is activated beforehand.
Procedure
Remote Control
Each time you press the button, Freeze turns on or off.
q
•Audio does not stop.
•The image source continues to play back the moving images
even while the screen is frozen, and so it is not possible to
resume projection from the point where it was paused.
•If the [Freeze] button is pressed while the Configuration Menu
or a Help screen is displayed, the menu or Help screen being
displayed is cleared.
Changing the Aspect Ratio
Change the Aspect Ratio g when video equipment is connected so that
images that have been recorded in digital video or onto DVDs can be
viewed in 16:9 wide-screen format. Change the Aspect Ratio when
projecting computer images at full size.
The changing methods and the types of Aspect ratio are as follows.
Changing methods
Procedure
Remote Control
Each time you press the button, the Aspect name is displayed on the
screen and the Aspect changes.
If you press the button while the Aspect name is displayed on the
screen, it changes to the next Aspect Mode.
q
The aspect ratio can also be set using Aspect in the Signal menu
from the Configuration Menu.sp.32

Changing the aspect for computer images
You can change the Aspect as follows. This projector offers WXGA 1280x800 resolution (Aspect Ratio 16:10). When projecting onto 16:9 screens, set the
Aspect to 16:9.
Set Values Operation Projection example
Normal Projects to the full projection size retaining the Aspect of
the input image.

Projects in an appropriate aspect based on information
from the input signal.
16:9 Projects to the full projection size at an Aspect of 16:9. When a 1024x768 signal is input
Full Project at full size. When a 1024x768 signal is input
Functions for Enhancing Projection
19

Set Values Operation Projection example
Zoom Projects the input image at the lateral direction aspect size
as it is. Parts that extend beyond the projection size are not
projected.
When a 1024x768 signal is input
Native Projects at the resolution of the input image size to the
center of the screen. This is ideal for projecting clear images.
If the image resolution exceeds 1280x800, the edges of the
image are not projected.
When an 800x600 signal is input When an 1400x1050 signal is input
q
If parts of the image are missing, set Wide or Normal in Resolution from the Configuration Menu depending on the size of the computer panel.
