Positioning your projector20
When the screen aspect ratio is 4:3 and the projected picture is 16:10
Table B2: The screen aspect ratio is 4:3 and the projected picture is 16:10
There is 3% tolerance among these numbers in Table A1, Table A2, 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.
