Screen size and projection distance
Adjust the distance from the lens to the screen to achieve your desired screen size.
You will need to have specified the Normal Throw (DILA1080MF1) or Short Throw
(DILA1080MF1S) version of this projector when ordering. The Normal Throw version uses
a 1.9x power zoom lens, while the Short Throw version has a 1.4x power zoom lens. As a
result, the Normal Throw version displays a given image size on a screen up to about 150%
as far away as the same-sized image displayed by the Short Throw version. In most cases,
especially when the projector is mounted in a projection room, the Normal Throw version
will be most appropriate. When the projector is used in a smaller room, however, the Short
Throw version will probably be more effective. The relationship of projection distance and
screen size for both versions is given by the table below.

The projection screen sizes (recommended) and projection distances in the table below are
provided only as a guide. Please use them as reference during installation. The projected
image size may vary depending on the manufacturing tolerance of the lens.
Use a projection image of 16:9 aspect ratio for setup adjustment.

Lens shift setting
This unit comes with a Lens shift feature that enables you to adjust the projection screen
position up or down. Adjust accordingly depending on the installation conditions.
The shift level is between 0% and 60%. The shift level is set to 50% as the default. The
following diagram shows the range of adjustment:
The position of the projection screen may be out of alignment due to the gear movement.
When lens shift setting (adjustment) is completed, mount the lens shift cover to this unit.
