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.
