							Positioning your projector 15
Obtaining a preferred projected image size
The distance from the projector lens to the screen, the zoom setting, and the video format 
each factors in the projected image size.
Projection dimensions
Refer to Dimensions on page 61 for the center of lens dimensions of this projector 
before calculating the appropriate position.
The screen aspect ratio is 4:3 and the projected picture is 4:3
For example, if you are using an 120-inch screen, the recommended projection distance is 
4848 mm and the vertical offset is 137-229 mm.

							Positioning your projector 16If 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 projectors 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.

•  Lens shift adjustment will not result in a degraded picture quality. In the unlikely event that 
the image distortion is produced, see Adjusting the projected image on page 22 for details. 
						

							Connection 18
Connection
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. Ensure the cables are firmly inserted.
•  In the connections shown below, 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 below 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 + F3 or CRT/LCD key turns the external display on/off. Locate a function key labeled CRT/
LCD or a function key with a monitor symbol on the notebook. Press FN and the labeled function key 
simultaneously. Refer to your notebooks documentation to find your notebooks key combination.

•  The D-Sub output only works when an appropriate D-Sub input is made to the COMPUTER 1 jack.
•  If you wish to use this connection method when the projector is in standby mode, make sure the 
Monitor Out function is turned on in the SYSTEM SETUP: Advanced menu. See Standby Settings 
on page 50 for details.
Connecting video source devices
You need only connect the projector to a video source device using just one of the 
connecting methods; however, each provides a different level of video quality. The method 
you choose will most likely depend upon the availability of matching terminals on both the 
projector and the video source device as described below:
Connecting audio
The projector has built-in mono speaker(s) which are designed to provide basic audio 
functionality accompanying data presentations for business purposes only. They are neither 
designed nor intended for stereo audio reproduction use, as may be expected in other 
home theater or home cinema applications. Any stereo audio input (if provided), is mixed 
into a common mono audio output through the projector speaker(s).
The built-in speaker(s) will be muted when the AUDIO OUT jack is connected.
•  The projector is only capable of playing mixed mono audio, even if a stereo audio input is connected. See 
Connecting audio on page 19 for details.
•  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.
Playing sound through the projector
You can make use of the projector (mixed mono) speaker(s) in your presentations, and 
also connect separate amplified speakers to the AUDIO OUT socket of the projector.
If you have a separate sound system, you will most likely want to connect the audio output 
of your Video source device to that sound system, instead of to the mono audio projector.
You can also use a microphone to output the sound through the projector speaker(s).
Once connected, the audio can be controlled by the projector On-Screen Display (OSD) 
menus. See Audio Settings on page 49 for details.

							Connection 20The table below describes the connection methods for different devices, and where the 
sound is from.
The projector can play sound if the connected RJ45 cable or USB cable carries audio signal. There is no need 
to connect the audio cable when the USB Display or Network Display source is selected.
About the microphone input
•  If you wish to use a microphone, connect a 3.5 mini jack cable microphone to the 
projector.
•  You can use a wireless microphone as long as a wireless module is attached to the 
projector’s microphone input jack and it works well with the associated devices. To 
ensure a quality use of the wireless microphone, it is recommended that your 
microphone conforms to the specifications listed in the table below. 
•  To adjust microphone volumes
• Directly set microphone volume levels in the SYSTEM SETUP: Advanced 
> Audio Settings > Microphone Volume menu. 
•  To make the microphone input available when the projector is in standby mode, turn 
on the SYSTEM SETUP: Advanced > Standby Settings > Microphone menu.
•  If the microphone is not working, check the volume setting and cable connection.
• You might get feedback noise from the microphone when you are too close to the 
speaker(s) of the projector. Move the microphone away from the speaker(s) of the 
projector. The greater volume you require, the greater distance you need to be away 
from the speaker(s) to prevent the noise.
