Positioning your projector

Obtaining a preferred projected image size

The distance from the projector lens to the screen, the zoom setting, and the video format
each factors in the projected image size.
The projector should always be placed horizontally level (like flat on a table), and positioned
directly perpendicular (90° right-angle square) to the horizontal center of the screen. This

prevents image distortion caused by angled projections (or projecting onto angled surfaces).

If the projector is mounted on a ceiling, it must be mounted upside-down.
This projector is equipped with a movable lens. See

"Shifting the projection lens vertically"

below for details. You can see the diagrams on pages

13

and

14

for the vertical offset values

in the dimension tables that are measured when the lens is shifted fully up or down.
If the projector is positioned further away from the screen, the projected image size
increases, and the vertical offset also increases proportionately.
When determining the position of the screen and projector, you will need to account for both
the projected image size and the vertical offset dimension, which are directly proportional to

the projection distance.
We have provided separate tables of dimensions for both 16:9 and 4:3 screen ratios to assist

you in determining the ideal location for your projector. There are two dimensions to

consider, the perpendicular horizontal distance from the center of the screen (projection
distance), and the vertical offset height of the projector from the horizontal edge of the

screen (offset).

Shifting the projection lens vertically

The vertical lens shift control provides flexibility for installing your projector. It allows the

projector to be positioned slightly above or below the top level of the projected images.
The lens shift (offset) is expressed as a percentage of the projected image height. It is

measured as an offset from the projected image's vertical center. The projector is equipped

with + 60% and - 40% vertical lens shift. You can shift the projection lens upwards or
downwards within the allowable range depending on your desired image position.
To adjust the vertical position of the projection lens:
1.

Press LENS or / (when the OSD menu is not activated)

on the remote control to display the adjustment page.

(Pressing ENTER in the Color > Lens Shift menu performs the
same function.)

2.

To raise the projected image, press on the remote

control.
To lower the projected image, press on the remote

control.
