Changing the Projected Image

Use the following methods to switch images for projection.

•Switching by source search

The projector automatically detects signals being input from connected equipment, and the image being input from the equipment is projected.

•Direct switching

Switch by pressing the button for the target input port on the remote control.

Switching by Automatic Detection of Input Signal (Source Search)

You can project the target image quickly because the [Source Search] button skips input ports where no image is being input.

Computer

S-Video

Video

Slideshow*		USB Display		HDMI*

13

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.

Changing the Projected Image	14

The following screen showing the status of image signals is q 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 connected equipment you want to use is projecting. If no operation is performed after about 10 seconds, the screen closes.

Direct Switching by Remote Control

You can switch directly to the targeted source by pressing a button on the remote control.

Refer to the following for button operation. s p.9

Functions for Enhancing Projection	15

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. This is the brightest
	mode and reproduces shadow tones well.
Game	Ideal for making presentations using color materials
	in a bright room.
Living Room	Ideal for making presentations using black-and-
	white materials in a bright room.
Theater	Ideal for watching films in a dark room. This gives
	images a natural tone.
Photo*1	Ideal for projecting still pictures, such as photos, in a
	bright room. This makes images vivid and brings
	them into contrast.
Sports*2	Ideal for watching TV programmes in a bright room.
	This makes images vivid and brings them to life.
sRGBg	Ideal for images that conform to the sRGB color
	standard.
Dark Wall	Even if you are projecting onto a blackboard
	(greenboard), this setting gives your images a natural
	tint, just like when projecting onto a screen.

Hiding the Image and Sound Temporarily (A/V Mute)

You can use this when you want to focus the audience's attention on what you are saying, or if you do not want to show details such as when you are changing between files during presentations from a computer.

Procedure

Remote control

Projector

Each time you press the button, or the A/V mute slide is opened or closed, A/V Mute turns on or off.

Functions for Enhancing Projection

• If you use this function when projecting moving images, q 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.

•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 in the configuration menu. s p.35

•When the A/V mute slide is closed and A/V Mute begins, the power supply can be set to automatically turn off after about 30 minutes by setting "Extended" - "Operation" - "Lens Cover Timer" in the configuration menu. s p.36

18

Freezing the Image (Freeze)

When the moving image on the screen is frozen, the image continues to project, 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.

Functions for Enhancing Projection

q	• Audio does not stop.
	• The image source continues to play back the moving
	images even while the screen is frozen, 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.
	• Freeze still works while E-Zoom is being used.

19

Changing the Aspect Ratio

When you connect video equipment and project images that have been recorded in digital video or onto DVDs in 16:9 wide-screen format, change the aspect ratiog. Changing the aspect ratio is also required when you want to project computer images at full size.

Switching methods and types of aspect ratio are as follows.

f Switching methods

Procedure

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 This can also be set using "Aspect" from the "Signal" menu in the configuration menu. s p.32

fChanging the aspect of computer image/HDMI image

When projecting input images from the Computer input port or HDMI input port, the aspect ratio can be changed as follows. The projection size is 1280 x 800 dots (aspect ratio 16:10) due to WXGA panel resolution. When projecting on to 16:9 screens, set the aspect to "16:9".

Security Functions

The projector has the following enhanced security functions.

•Password protect

You can limit who can use the projector.

•Control Panel Lock

You can prevent people from changing the settings on the projector without permission.

•Anti-Theft Lock

The projector is equipped with various types of anti-theft security devices.

Managing Users (Password Protect)

When the Password Protect function is activated, people who do not know the password cannot use the projector to project images even if the projector power is on. Furthermore, the user's logo that is displayed when you turn on the projector cannot be changed. This acts as an anti-theft device as the projector cannot be used even if it is stolen. At the time of purchase the Password Protect function is not activated.

fType of Password Protect

The following two kinds of password protect settings can be made according to how the projector is being used.

1."Power On Protect"

When "Power On Protect" is "On", the password must be entered whenever the projector is turned on after it has been disconnected from the power supply to which it was connected the last time the password was entered. If the correct password is not entered, projection does not

start.

2."User's Logo Protect"

Even if someone tries to change the user's logo set by the owner of the projector, it cannot be changed. When "User's Logo Protect" is set to "On" the following setting changes are prohibited.

•Capturing a user's logo

•Changing settings of "Display Background", "Startup Screen", and "A/V Mute" in the "Display" setting in the configuration menu.

A commercially available theft-prevention wire lock can be passed through the installation point to secure the projector to a desk or pillar.
