The above numbers are approximate and may be slightly different from the actual measurements. Only the recommended screen sizes are listed. If the your screen size is not in the table above, please contact your BenQ dealer for assistance.
An examination of the table reveals that you can place the projector lens in the range from 1.82 to 12.57m distance from the screen, which will give you a projected image from 50" (1.02 x 0.76m) to 300" (6.1 x 4.57m).
Shifting the projection lens vertically
The vertical lens shift control provides flexibility for installing your projector. It allows the projector to be positioned slightly above or below
the top level of the projected images.
The lens shift (offset) is expressed as a percentage of the projected image height. It is measured as an offset from the projected image's vertical center.
The projector is equipped with + 100% vertical lens shift. You can shift the
projection lens upwards or downwards within the allowable range depending on your desired image position. When the LENS button on the remote control or LENS SHIFT buttons (c or d) on the projector is pressed, an adjustment bar displays on the screen.
To raise the projected image, press the Lens Shift c button on the projector or the c button on the remote control.
To lower the projected image, press the Lens Shift d button on the projector or the d button on the remote control.
