• 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.
If you use a non-BenQ brand projector mounting kit, there is a safety risk that the projector may fall down due to an improper attachment through the use of the wrong gauge or length screws.
Adjusting the projector position 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. You can turn the knobs on the projector to shift the projection lens in any direction within the allowable range depending on your desired image position.
Adjusting the projected image Adjusting the projection angle If the projector is not placed on a flat surface or the screen and the projector are not perpendicular to each other, the projected image becomes trapezoidal. You can screw the adjuster feet to fine-tune the horizontal angle.
Connection Before connecting, carefully read the operating instructions for connecting the external device. When connecting a signal source to the projector, be sure to: 1. Turn all equipment off before making any connections. 2. Use the correct signal cables for each source. 3.
