15 Positioning your projector
LH710/LH710D/LH930/LH930D
• The screen aspect ratio is 16:9 and the projected picture is in a 16:9 aspect ratio
For example, if you are using a 120-inch screen, the recommended projection distance is 3440 mm.
If your measured projection distance is 4000 mm, the closest match in the "Projection distance (mm)"
column is 4014 mm. Looking across this row shows that a 140'' (about 3.6 m) screen is required.
• To optimize your projection quality, we suggest you do the projection within non-gray area.
• All measurements are approximate and may vary from the actual sizes.
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.
