Projection dimensions
Installation for a 16:9 ratio screen
The distance from the projector lens to the screen, the zoom setting, and the video format
each factors in the projected image size.

Vertical offset (A)*
*The vertical offset value is the vertical distance from the bottom edge of the image
(when the projector is placed on a table, diagram on the left), or top edge of the
image (when the projector is ceiling mounted, diagram on the right) to the centerline
of lens.
Due to the lens optical characteristics, every projector has its vertical offset ratio.
The vertical offset value normally gets larger while the projection distance increases.
The screen aspect ratio is 16:9 and the projected picture is in 16:9 aspect ratio

To optimize your projection quality, we suggest doing the projection by following the
values in the non-gray cells. The values in the gray cells are for reference only.
All measurements are approximate and may vary from the actual sizes.
If you want a permanent installation of the projector, we recommend that you
use the actual projector to physically test the projection size, distance, and the projector's
optical characteristics prior to the installation. This helps you
determine the exact mounting position which best suits your installation.
If your screen size is not in the table above, please contact your dealer for
assistance.
