Positioning your projector
16
If your measured projection distance is 5.5 m (5500 mm), the closest match in the
"Distance from screen [mm]"
column is 5633 mm. Looking across this row shows that a
130'' (about 3.3 m) screen is required.
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.
Shifting the projection lens
The lens shift control provides flexibility for installing your projector. It allows the
projector to be positioned off the center of the screen.
The lens shift is expressed as a percentage of the projected image height or width. It is
measured as an offset from the projected image’s vertical or horizontal center. You can
shift the projection lens within the allowable range depending on your desired image
position.
To shift the projection lens, press to open the cover on the projector to expose the lens
shift knob. Rotate the knob clockwise or counterclockwise until the screen is positioned
where you want it.

To avoid causing damage to the lens shift device, rotate the screw driver slowly and gently.
