Positioning your projector 17
Projection dimensions
Refer to "Dimensions" on page 60 for the center of lens dimensions of this projector
before calculating the appropriate position.
There is 3% tolerance among these numbers due to optical component variations.
BenQ recommends that if you intend to permanently install the projector, you should
physically test the projection size and distance using the actual projector in situ before you
permanently install it, so as to make allowance for this projector's optical characteristics.
This will help you determine the exact mounting position so that it best suits your installation
location.
