If flickering, fuzziness or interference appear 
in images that are input from the computer, 
and this cannot be fixed using automatic setup, 
you will need to adjust the sync
 manually 
using the following procedure.
Procedure
1Press the [Menu] button on the 
remote control, and then select 
Sync. from the Video 
menu.
For details on this operation, refer to 
Using the Configuration Menus. 
(p.56)
2Press the [ ] and [ ] buttons 
to set the sync value.
The sync value increases or 
decreases each time a button is 
pressed.
3After making the adjustment, press the [Menu] button to exit 
the configuration menu.
Tip :
 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 picture. However, pictures with lots of lines and shading will tend to 
show incorrect tracking adjustments more clearly, so be sure to check the tracking 
adjustment first.
 It may also be possible to fix flickering and fuzziness by adjusting the brightness, 
contrast
 , sharpness and keystone correction settings.

Selecting the Colour Mode
The following six preset colour 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 colour mode that corresponds to 
the projected images. The brightness of the images will vary depending on 
which colour mode is selected.
Procedure
The colour mode changes as follows 
each time the [Color Mode] button on 
the remote control is pressed.
Normal → Meeting → Presentation → 
Theatre → Game → sRGB ...
The current setting appears in the top-right 
corner of the screen each time the colour mode 
is changed.
The default colour mode setting is Normal 
when computer image signals are being input, 
and Theatre when component video
 or 
video signals are being input.
Tip :
The colour mode can also be set using the Color Mode command in the Video menu. 
(p.47, 49)

Functions for Enhancing Projection
This section describes the various useful functions that can be used to enhance 
presentations.
A/V Mute
This function momentarily pauses the image and sound.
For example, it can be used when you do not want to show viewers details of 
operations such as selecting different files while computer images are being 
projected.
However, if you use this function when projecting moving images, the images 
and sound will still continue to be played back by the source, and you cannot 
return to the point where the mute function was activated.
Procedure
Press the [A/V Mute] button on the 
remote control.
The image and sound will then be paused.
Press the [A/V Mute] button on the remote 
control to continue normal projection.
When the images and sound have been momentarily paused, one of the 
following two types of display appears depending on the A/V Mute setting in 
the Setting menu. (p.51)MenuA/V Mute

Freeze
This function pauses only the projected images. The sound keeps playing 
without pausing.
The image source will still be playing back the images even while projection is 
paused, and so it will not be possible to resume projection from the point where 
it was paused.
Procedure
Press the [Freeze] button on the 
remote control.
The images will then be paused.
To continue projecting the images, either press 
the [Freeze] button again or press the [ESC] 
button.
Tip :
 Pressing the [Freeze] button also clears menu displays and help messages.
 The Freeze function still works while the E-Zoom function is being used. 
However, in this case the Freeze function can only be cancelled by pressing the 
[Freeze] button.

Wide-screen Projection of Component Video and Video 
Images (Changing the Aspect Ratio)

component video images (YCbCr and YPbPr) or video images (S-Video or 
composite video) are being projected. Images which have been recorded in 
digital video or onto DVDs can be viewed in 16:9 wide-screen format. 
Procedure
1Press the [Menu] button on the 
remote control, and then select 
Aspect Ratio from the 
Video menu.
For details on this operation, refer to 
Using the Configuration Menus. 
(p.56)
2Press the [ ] and [ ] buttons 
to set the aspect ratio to either 
4:3 or 16:9, and then press 
the [Enter] button.
3After making the adjustment, press the [Menu] button to exit 
the configuration menu.

Using the Configuration Menu Functions
The configuration menus can be used to carry out a variety of settings and 
adjustments.
The menus have a hierarchical structure, with a main menu that is divided into 
sub-menus, which are further divided into other sub-menus.
The remote control is used to operate the menus. Refer to Using the 
Configuration Menus (p.56) for details on using the menus.
List of Functions
 The functions in the Video menu apart from Input Signal, Auto Setup 
and Video Signal cannot be adjusted while no image signal is being input.

The functions which appear in the Video menu will change depending on the 
type of input source being used for the image signal. Functions which are not 
available in the Video menu for a particular input source cannot be adjusted.
