column is 986 mm. L ooking across this row shows that a 90'' (about 2.2 m) screen is required.
• All measurements are approximate and may vary from the actual sizes.
B enQ 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.
• To optimize your projection quality, we suggest doing the projection by following the values in the non-gray cells.
• The values in the gray cells are for reference only.
