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".

For information on optional accessories, see s "Optional Accessories and Consumables" p.61.

Useful Functions

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

Changing the Projected Image		13

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.

Changing the Projected Image		14

Switch to the target image by Remote Control

You can change directly to the target image by pressing the following buttons on the Remote Control.

Remote Control

AChanges to images from the Computer input port.

BEach time the button is pressed, the image cycles through Video, S-Video, and HDMI input ports.

CChanges to the Slideshow image.

Functions for Enhancing Projection

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
