Adjusting the Screen Image
You can adjust the screen image in order to obtain the best possible picture.
The size of the projected image is basically determined by the distance from the projector to the screen. 
(Refer to the Setup Guide.)
The following procedures explain how to adjust the screen image once the projector itself has been set up.
ProcedureTurn the zoom ring on the projector to 
adjust the image.
The image can be enlarged in this way to 1.35 
times the normal size.
If you would like to enlarge the image further, 
move the projector further away from the screen. 
(Refer to the Setup Guide.)
The projector should be as perpendicular to the screen as possible.
If the projector cannot be set up so that it is exactly perpendicular to the screen, it can be set up so that it is 
tilting slightly horizontally or vertically. To tilt the projector upward, adjust the front adjustable foot to tilt the 
projector at an angle of up to a maximum 12°.
ProcedureWhile pressing the foot adjust button, 
lift up the front of the projector so that 
the front adjustable foot can extend.
Extend the front adjustable foot until the desired 
angle is obtained, and then release the foot adjust 
button.
To retract the foot, press and hold the foot adjust 
button and gently lower the projector.

Adjusting the Image Angle
•
•• •When the foot is adjusted, it may cause the projected images to become distorted. Use the 
keystone correction function to adjust this distor tion. (p.11)

Basic Operations
If the projector is set up so that it is at an angle to the screen, a type of distortion known as keystone 
distortion may occur.
Keystone correction can be carried out if the angle of the projector is within a range of approximately 15° 
vertically from the perpendicular.
Procedure
Correcting Keystone Distortion
•
•• •When keystone correction is carried out, the projected image will become smaller.
•
•• •The keystone correction settings are memorized, so that if you change the position or angle of 
the projector, you may need to readjust the keystone correction settings.
•
•• •If the images become uneven in appearance after keystone correction is carried out, decrease 
the “Sharpness” setting. (p.25, 27)
•
•• •Keystone correction can also be carried out using the projector’s environment setting menu. 
(p.30)
•
•• •If the value displayed in the gauge on the screen stops changing when horizontal or vertical 
keystone correction is being carried out, it indicates that the limit for horizontal or vertical 
keystone correction has been exceeded. Check that the projector has not been set up at an 
angle which exceeds the proper limit.

When setting up the projector, you can project a test pattern onto the screen and use this test pattern to adjust 
the projected images before a video source has been connected. The following two types of test pattern are 
available.
•
•• •Crosshatch
•
•• •Grayscale pattern
The test pattern changes as shown below each time the [Pattern] button on either the remote control or the 
projectors control panel is pressed.
Crosshatch → Grayscale pattern → No pattern
Displaying a Test Pattern
The full environment setting menu cannot be displayed while a test pattern is being projected. If 
you need to change a setting, use the line menu or the [Keystone] buttons on the projectors 
control panel.
This can be used to adjust the focus and correct keystone distortion.
This can be used to adjust dark and light shades to the desired shade.
The adjustment can be carried out using the Color Temp
 or RGB 
setting in the Color Adjustment item of the projectors Video menu.

Basic Operations
Adjusting the Image Quality
The quality of the screen images can be adjusted as follows.
ProcedureTurn the focus ring to adjust the image 
focus.
The following five color modes have been preset for use with images with varying characteristics. You can 
use these color modes to obtain the optimum image quality easily, just by selecting whichever color mode 
best suits the images. The brightness of the projected images will vary depending on the mode.
ProcedureThe color mode changes as shown 
below each time the [Colortune] button 
on either the remote control or the 
projectors control panel is pressed.
Dynamic → Theatre → Natural → PC → sRGB
The current setting appears on the screen each 
time the color mode changes.
Focusing the Screen Image
•
•• •If the surface of the lens is dirty or misted 
over as a result of condensation, it may 
not be possible to adjust the focus 
correctly. If this happens, clean or de-mist 
the lens. (p.44)
•
•• •If the projector is positioned outside the 
normal projecting range of 0.9 - 13 m (2.9 
- 42.6 ft.), it may not be possible to obtain 
the correct focus. If you have trouble 
obtaining the correct focus, check the 
projection distance.

The aspect ratio for projected images can be selected from the following five types of setting. However, the 
aspect ratio settings that can be selected will vary depending on the input signal.
ProcedureThe aspect ratio changes as shown 
below each time the [Aspect] button on 
either the remote control or the 
projectors control panel is pressed.

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 images output in 4:3 format are 
projected using the projectors squeeze

horizontally and the image will appear 
elongated.

Images output in 4:3 format are truncate at 
top and bottom by a set amount and then 
projected in a 16:9 format.
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 best for 
sections of the image that are not resized.
The portions that are not vertically resized 
will appear with higher image quality.
If the input signal resolution is 1280 x 720

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.

This function lets you adjust computer images to the optimum settings.
Automatic adjustment involves adjustment of tracking
 display position and synchronization (sync).
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.
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 projectors environment setting menu. (p.27)

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’s environment setting 
menus.
There are two types of projector’s environment setting menus used:
•
•• •Full menus : These menus can be used to set all items in the environment setting menus.
•
•• •Line menus : These menus can be used to change the “Vi d e o” settings while viewing the images 
being projected. The “Vi d e o” menu is the most commonly used of the environment 
setting menus. (p.20)
Menus can be operated using the projectors control panel and also by using the remote control.
Procedure
1Press the [Menu] button on either the 
remote control or the projectors 
control panel.
The environment setting menu appears.
Full menus consist of a main menu and sub-
menus. The sub-menu that corresponds to the 
currently-selected item in the main menu 
(displayed in yellow) appears.
2Select the items to be changed in the 
main menu.
If using the projectors control panel, press the 
 and   buttons.
If using the remote control, tilt the [Select] button 
up and down.
