Adjusting and Changing the Image
Adjusting the Image Quality
Adjusting Computer Images and RGB Video Images
Automatic Setup
Automatic setup detects analog RGB signals coming from a connected
computer, and automatically adjusts these signals so that the optimum
images can be obtained.
Automatic setup involves adjustment of Tracking, Position, and Sync
(synchronization).
If "Auto Setup" in the "Signal" menu is set to "Off", automatic setup is not
carried out. In this case, press the [Auto] button on the remote control or the
[Enter] button on the projector's control panel to make the adjustment while
computer or RGB video images are being projected.
Adjusting the Tracking
If vertical stripes appear in the projected computer
or RGB video images, and this cannot be fixed using
automatic setup, you will need to adjust the Tracking
manually using the following procedure.
1Select "Signal" from the configuration
menu, and then select "Tracking".
Check the buttons you can use and the operations they perform in the
guide at the bottom of the screen.
Using the remote control Using the control panel
p• If you try to make the adjustment while other functions such as E-zoom or
Freeze are in use, these functions are canceled and then the adjustment is
made.
• Sometimes the signals may not be adjusted correctly depending on the type
of computer or RGB video signals being input. In such cases, use the
configuration menu commands to adjust the tracking and sync settings
manually. See page 33.

2Adjust the tracking until the vertical stripes disappear from the
image.
The tracking value increases or decreases each time a button is
pressed.
3Press the [Menu] button to exit the configuration menu.
Adjusting the Sync
If flickering, fuzziness or interference appear in
computer or RGB video images, and this cannot be
fixed using automatic setup, you will need to adjust
the Sync (synchronization) manually using the
following procedure.
1Select "Signal" from the configuration
menu, and then select "Sync.".
Check the buttons you can use and the operations they perform in the
guide at the bottom of the screen.
2Adjust the synchronization until the horizontal noise disappears
from the image.
pThe image will flash when continuous tracking adjustment is carried out,
but this is normal.

Adjusting the Image Quality
The sync value increases or decreases each time a button is pressed.
3Press the [Menu] button to exit the configuration menu.
Selecting the Projection Quality (Color Mode)
The following seven preset color modes are
available for use depending on the characteristics of
the images that are being projected. You can easily
obtain the optimum image quality simply by
selecting the color mode that corresponds to the
projected images. The brightness of the images will
vary depending on which color mode is selected.
p• If you adjust the sync without adjusting the tracking first, it will not be
possible to get the best adjustment results. Incorrect tracking adjustment
may not be noticeable with some types of images. However, images with
lots of lines and shading will tend to show incorrect tracking adjustments
more clearly, so check the tracking adjustment first.
• Flickering and fuzziness may also occur when the brightness, contrast,
sharpness, zoom, and keystone correction settings are adjusted.
Using the remote control Using the control panel
Mode Application
Photo (When computer and RGB video images are being input)
The images are vivid and contrast is increased. Ideal for projecting
still pictures, such as photos, in a bright room.
Sports (When component video, S-video, or composite video images are
being input)
The images are vivid and brought to life. Ideal for watching TV
programs and so on in a bright room.
Presentation Ideal for giving presentations in a bright room
Theatre Gives images a natural tone. Ideal for watching films in a dark
room.
Game Excels at emphasizing dark gradations. Ideal for playing video
games in a bright room.
sRGB Ideal for images that conform to the sRGB color standard
Blackboard Even if you are projecting onto a blackboard (green board), this
setting gives your images a natural tint, just like when projecting
onto a screen

15
Adjusting the Image Quality
Each time you press the button, the color modes change in the following
order.
The current setting appears in the top-right corner of the screen each time the
color mode is changed. While the color mode name is displayed on the
screen, it does not change to the next color mode setting unless you press the
button.
pThe color mode can also be set using the "Color Mode" command in the
"Image" menu. See page 32.

Functions for Enhancing Projection
Additional Projector Functions
This chapter explains functions used when giving presentations and for using
the projector’s security functions.
Functions for Enhancing Projection
Muting the Image and Sound (A/V Mute)
For example, this can be used if you want to pause the projection for a
moment and focus the audience’s attention on what you are saying. Or if you
are making a computer presentation and you do not want to show details,
such as selecting different files.
You can temporarily turn off the image and sound in two ways:
◗When you close the lens cover, projection and sound are turned off. Open
the lens cover to restore projection and sound.
◗When you press the A/V Mute button on the remote control, projection and
sound are turned off. If you saved a user’s logo (see page 28), you can set
it to display when you press the A/V Mute button (see page 35). Press the
A/V Mute button again to restore projection and sound.
Using the remote control
Pressing the [A/V Mute] button
stops projection and sound.
Closing the lens cover stops
projection and sound.
Using the projector
p• If you’re watching a moving picture, the video source continues to play
while the screen is dark. You should pause the video if you wish to resume
playback where you stopped it.
• The screen display in A/V mute can be chosen from black, blue, or a logo
by using "Extended" -"Display" - "A/V Mute" in the configuration menu.

20
Functions for Enhancing Projection
Freezing the Image
The source image continues to project even when the screen is frozen. You
can still perform operations such as changing files, without projecting any
images.
You can turn this function on or off by pressing the [Freeze] button.
Changing the Aspect Ratio
This function changes the aspect ratio of images from 4:3 to 16:9 when
component video, S-video, or composite video images are being projected.
Images which have been recorded in digital video or onto DVDs can be
viewed in 16:9 wide-screen format.
The display is changed whenever you press the button.
p• Sound does not stop.
• Even though the image on the screen is frozen, the image source
continues to project, and so it is not possible to resume projection from
the point where it was paused.
• Pressing the [Freeze] button also clears configuration menu displays
and help messages.
• The freeze function still works while the E-Zoom function is being used.
Remote control
pYou can also make this setting using the "Resize" command in the
"Signal" menu.
