Obtaining A Preferred Projected Image Size - BenQ MX611 User Manual

Obtaining a preferred projected image size

The distance from the projector lens to the screen, the zoom setting (if available), and the video format
each factors in the projected image size.

For example, if you are using a 120-inch screen, the recommended projection distance is 5011 mm.
If your measured projection distance is 6600 mm, the closest match in the
column is 6681 mm. Looking across this row shows that a 160'' (about 4.1 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.
