							Positioning your projector 14
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 55 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 
4755 mm and the vertical offset is 183 mm.
If your measured projection distance is 6.0 m (6000 mm), the closest match in the 
Projection distance (mm) column is 5943 mm. Looking across this row shows that a 150 
(about 3.8 m) screen is required.

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 
4400 mm and the vertical offset is 91 mm.
If your measured projection distance is 6.0 m (6000 mm), the closest match in the 
Projection distance (mm) column is 5500 mm. Looking across this row shows that a 150 
(about 3.8 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.

Monitor Out function is turned on in the SYSTEM SETUP: Advanced  menu. See Standby Settings 
on page 44  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 presentation s for business purposes only. They are not 
designed for, nor intended for stereo audio reproduction use as might be expected in 
home theater or home cinema applications. An y 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 capa ble of playing mixed mono audio, even if a stereo audio input is connected. See 
Connecting audio on page 17  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.
