16 Positioning your projector
For example, if you are using a 100-inch screen, the recommended projection distance is 2933
mm.
If your measured projection distance is 2000 mm, the closest match in the "Projection distance
(mm)" column is 2053 mm. Looking across this row shows that a 70'' (about 1.8 m) screen is
required.
To optimize your projection quality, we suggest doing the projection by referring to the values listed in the
non-gray rows.
The values in the gray cells are for reference only.
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.

17Positioning your projector
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 Kensington 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.
• Consider the surrounding temperature where the projector is ceiling/wall mounted. If a heater
is used, the temperature around the ceiling/wall 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.

3. Ensure the cables are firmly inserted.
• In the connections above, some cables may not be included with the projector (see Shipping contents on
page 8). They are commercially available from electronics stores.
• The connection illustrations are for reference only. The rear connecting jacks available on the projector
vary with each projector model.
• Many notebooks do not turn on their external video ports when connected to a projector. Usually a key
combo like FN + function key with a monitor symbol turns the external display on/off. Press FN and the
labeled function key simultaneously. Refer to your notebook's documentation to find your notebook's key
combination.
• If the selected video image is not displayed after the projector is turned on and the correct video source
has been selected, check that the video source device is turned on and operating correctly. Also check
that the signal cables have been connected correctly.
