16 Positioning your projector

For example, if you are using a 120-inch screen, the recommended projection distance is 4702 mm.

If your measured projection distance is 4000 mm, the closest match in the "Projection distance (mm)"

column is 3918 mm. Looking across this row shows that a 100'' (about 2.5 m) screen is required.

Mounting the projector

If you intend to mount your projector, we strongly recommend that you use a proper fitting BenQ

projector mounting kit and that you ensure it is securely and safely installed.

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.

Before mounting the projector

• Purchase a BenQ projector mounting kit from the place you purchased your BenQ projector.

• BenQ recommends that you also purchase a separate Kensington lock compatible security cable and

attach it securely to both the anti-theft lock slot on the projector and the base of the mounting

bracket. This will perform the secondary role of restraining the projector should its attachment to the

mounting bracket become loose.

• Ask your dealer to install the projector for you. Installing the projector on your own may cause it to

fall and result in injury.

• Take necessary procedures to prevent the projector from falling off such as during an earthquake.

• The warranty doesn’t cover any product damage caused by mounting the projector with a non-BenQ

brand projector mounting kit.

• 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.

17 Positioning your projector

• Consider the surrounding temperature where the projector is ceiling/wall mounted. If a heater is used,

the temperature around the ceiling may be higher than expected.

• Read the user manual for the mounting kit about the range of torque. Tightening with torque

exceeding the recommended range may cause damage to the projector and subsequently falling off.

• Make sure the power outlet is at an accessible height so that you can easily shut down the projector.

Adjusting the projector position

(LU930/LU930D/LH930/LH930D)

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.

To reach the highest or lowest projection position:

1. Turn (Up/Down).

2. When you feel it is reaching the limit, turn

(Left/Right) to the left or right and turn

again.

3. Repeat the step above until finding the suitable position you need.

• If you hear a “clicking sound” during the adjustment, it means that the knob is past its adjustment limit. Please

stop adjusting it, in order to avoid any unexpected damage, and turn the knob in the opposite direction, at least

to one step before the click.

• If you can’t turn it back, please press and turn the knob back at same time.

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.

To retract the feet, screw the adjuster feet in a

reverse direction.
