There is 3% tolerance among these numbers in the above two tables 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.
