There is 3% tolerance among these numbers in Table A, Table B1, and Table B2 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.
If you place the projector in a different position (to that recommended), you will have to tilt it down or up, or even turn it slightly left or right to center the picture on the screen. In these situations, some picture distortion will occur. To correct the distortion, see "Correcting picture distortion" on page 37 for details.
