Projection dimensions
Refer to 
 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.
