Positioning your projector
19
MW855UST
The screen aspect ratio is 16:10 and the projected picture is 16:10.
MH856UST
The screen aspect ratio is 16:9 and the projected picture is 16:9.
There is 5% tolerance among these numbers 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 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.
It is recommended to adjust focus 15 minutes after powering on due to the slight shifting of the
lens from temperature changing.
