Zoom -Subtitle- mode
Use this setting if the connected video 
source has a 16:9 output mode (Squeeze 
mode).
If images in squeeze mode are viewed on a 
4:3 TV screen, the images are compressed 
horizontally and elongated vertically. If 
Squeeze mode is selected on the projector, 
the images are projected correctly in their 
native wide-screen (16:9) format.

When 4:3 images with subtitles included 
are projected using the projectors Zoom 
Subtitle mode, the images are enlarged in 
the vertical and horizontal directions to 
resize them to 16:9 size.
Because the images are enlarged 
vertically, the subtitles may sometimes be 
displayed outside the actual projection 
area. If this happens, you can adjust the 
display position by choosing the Signal 
- Zoom Subtitle - V Size, V Position 
menu command (p.31)
•
•• •V Size
This adjusts the vertical enlargement 
ratio without changing the size in the 
horizontal direction.
•
•• •V Position
This moves the display position up.

Basic Operations
This adjusts computer images (INPUT A [RGB] and INPUT B [RGB] only) to the optimum condition.
Automatic adjustment involves adjustment of tracking
, display position and synchronization (Sync) for 
RGB signals.
ProcedureWhile an image is being projected from 
the computer, press the [AUTO] button 
on the remote control.
The screen will appear black while the 
adjustment is being made.
Through mode
Squeeze Through mode
Automatic Adjustment of Computer Images
Automatic adjustment may not work properly with some types of signals which are output by 
computers. In such cases, you may need to adjust the tracking and synchronization manually 
using the projector menu. (p.28)
If the input signal resolution is 1280 x 720 
dots or less, the images are projected onto 
the screen with the input signal resolution 
unchanged. Because of this, the size of the 
displayed images will change depending 
on the input resolution.
The picture quality will be the clearest for 
portions of the image that have not been 
resized horizontally or vertically.
If the input signal resolution is 1280 x 720 
dots or less, the input signal resolution is 
elongated horizontally and the images are 
projected at an aspect ratio of 16:9. 
Because of this, the size of the displayed 
images will change depending on the input 
resolution.
The portions that are not vertically resized 
will appear with higher image quality.

Functions for Enhancing Projection
This section describes the various useful functions that can be used to enhance projection.
The functions described here are used to set the adjustment values using the projector menus.
There are two types of projector menus used:
•
•• •Full menus : These menus can be used to set all items in the menus.
•
•• •Line menus : These menus can be used to change the “Image” settings while viewing the images 
being projected. The “Image” menu is the most commonly used of the menus. 
(p.22)
Menus can be operated using the projectors control panel and also by using the remote control.
Procedure
1
Press the [MENU] button on either the 
remote control or the projectors 
control panel.

(displayed in white) appears.
2Select the items to be changed in the 
main menu.
If using the projectors control panel, press the   
or  button.

This adjusts the hues of light shades to the desired hues.
Three modes are available, for adjusting Color Temperature
, flesh tones and each individual RGB color.
These adjustments are cumulative, so first carry out the basic Color Temp. and Flesh Tone adjustments 
while referring to the graph below, and then make fine adjustments using the Color Balance command. 
Use the Color Temp., Flesh Tone and Color Balance commands in the Image menu to adjust. 
(p.27, 29)
Color temperature and flesh tone adjustment modes
•
•• •The Color Temp. setting allows lighter colors to be 
adjusted so that they range from having a red tinge to 
having a blue tinge. When the color temperature is 
lower, the red content is greater and color tones appear 
softer. When the color temperature is higher, the blue 
content is greater and color tones appear fresher.
•
•• •The Flesh Tone setting adjusts the green component 
of image signals. If adjusted to the - side, the green 
component is reduced and colors appear purplish. If 
adjusted to the + side, the green component is increased. 
Adjust until the desired flesh tones are obtained.
Up to a maximum of six adjustment values in the Image and Signal menus can be memorize per input 
source, and settings for six different sources can be recorded, for a total of 36 possible settings. You can save 
the adjustment values for particular video scenes, and then use the memory button on the remote control to 
retrieve these settings at a single touch. (p.27, 29)
The following adjustment values can be stored in memory.

Using the Menu Functions
The menus are used to make various adjustments and settings. There are two types of projectors menus used: full menus 
and line menus. The following pages explain how to change the settings for the various menu commands, using full 
menus as illustrations.
Full menus consist of a main menu and sub-menus in a hierarchical structure.
Refer to Using the menus (p.20) for details on carrying out the various menu operations.
•
•• •If no signals are being input, settings other than “Color Temp.”, “Flesh Tone” and “Color Balance” in the 
“Image” menu cannot be adjusted.
•
•• •The items appearing in the “Image” menu will vary depending on the input signal that is being projected. 
Items in menus other than the menu for the signal currently being input cannot be adjusted.

Depending on the combination of the model of VCR and the type of video 
tape you are using, the VCR output signal level may be too high and the 
white level may become clipped. When playing back SECAM signals, 
clipped images will change and appear purplish. If this happens, reduce the 
white level slightly to cancel the clipping in order to remove the purplish 
tinge.0
