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.
Refer to the picture on the top for
the center of lens dimensions
before calculating the appropriate
position.
