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 6). They are commercially available 
from electronics stores.
Wireless connection (optional)
The Wireless module allows for simultaneous wireless connectivity to multiple computers 
which are wireless enabled. This saves you from having to swap data cables between the 
projector and different computers during a presentation. Wireless connectivity is most 
suitable for situations where multiple presenters with separate notebooks are required to 
seamlessly present individual presentations, like in meetings, conferences, lectures and, 
classrooms. 
Even though the Wireless module is not attached to the projector, everytime the projector is 
turned on, the status of wireless connection will display on the screen while the projector is 
searching for input signals during the start up procedure.
The Wireless module connects and attaches to the rear of the projector through the DVI-I 
socket.
While the Wireless module is attached to the projector, you cannot use the DVI-I socket for DVI 
cable connections.
Even though the projector may be using a wireless data connection, it still requires physical 
connection to a power outlet using its power cable.
You can purchase a BenQ wireless 
module from BenQ retailers. You 
should attach the wireless module 
to the projector before you connect 
any other cables. Refer to the user 
manual enclosed with the wireless 
module for connection and 
operation details.

Connecting Video source devices
This section describes how to connect the projector to Video source devices using video 
cables. Video cable connections are recommended for Video presentations. 
This projector also supports data (graphic) PC connection using wireless function. Wireless 
connection is not recommended for Video presentations. See Wireless connection 
(optional) on page 17.
You can connect your projector to various Video source devices that provide any one of the 
following output sockets:
•DVI
• Component Video
•S-Video
•Video (composite)
You need only connect the projector to a Video source device using just one of the above 
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:
Best video quality
The best available video connection method is DVI. If your source device is equipped with a 
DVI socket, based on the type of DVI connector you have, you can enjoy digital or high-end 
analog video quality.
See Connecting a Component Video source device on page 21 for how to connect the 
projector to a DVI source device and other details.
If no DVI source is available, the next best video signal is Component Video (not to be 
confused with composite Video). Digital TV tuners and DVD players output Component 
Video natively, so if available on your devices, they should be your connection method of 
choice in preference to S-Video or (composite) Video.
See Connecting a Component Video source device on page 21 for how to connect the 
projector to a component video device.
Better video quality
The S-Video method provides a better quality analog video than standard composite Video. 
If you have both composite Video and S-Video output terminals on your Video source 
device, you should elect to use the S-Video option.
See Connecting an S-Video source device on page 23 for how to connect the projector to 
an S-Video device.
Least video quality
Composite Video is an analog video and will result in a perfectly acceptable, but less than 
optimal result from your projector, being the least video quality of the available methods 
described here.
See Connecting a composite Video source device on page 24 for how to connect the 
projector to a composite Video device.
Connecting Audio
The projector has a built-in mono speaker which is designed to provide basic audio 
functionality accompanying data presentations for business purposes only. It is not designed 
for, nor intended for stereo audio reproduction use as might be expected in home theatre or 
home cinema applications. Any stereo audio input (if provided), is mixed into a common 
mono audio output through the projector speaker.  
						

							Connection 21 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. 
The audio connections illustrated in the following sections are provided for informational 
purposes only. You need not connect audio to the projector if there is an alternate sound 
system available, or if audio is not required.
Connecting a Component Video source device
Examine your Video source device to determine if it has a set of unused Component Video 
output sockets available: 
• If so, you can continue with this procedure.
• If not, you will need to reassess which method you can use to connect to the device.
To connect the projector to a Component Video source device through a 
Component Video to VGA (D-Sub) adaptor cable:
•With a  Component Video to VGA 
(D-Sub) adaptor cable:•With a DVI cable:
1. Take the (optional accessory) 
Component Video to VGA (D-Sub) 
adaptor cable and connect the end 
with 3 RCA type connectors to the 
Component Video output sockets of 
the Video source device. Match the 
color of the plugs to the color of the 
sockets; green to green, blue to blue; 
and red to red.
2. Connect the other end of the 
Component Video to VGA (D-Sub) 
adaptor cable (with a D-Sub type 
connector) to the D-SUB/COMP IN 
socket on the projector.1. Take a DVI cable and connect one 
end of the cable to the DVI output 
socket of the Video source device.
2. Connect the other end of the cable 
to the DVI-I socket on the projecto
r.
3. If you wish to make use of the projector (mixed mono) speaker, take a suitable 
audio cable and connect one end of the cable to the audio output socket of the 
computer, and the other end to the Audio socket of the projector. 
						

							Connection 22The final connection path should be like that shown in the following diagram:
• The projector is only capable of playing mixed mono audio, even if a stereo audio input 
is connected. See Connecting Audio on page 20 for details.
• Component Video is the only video output that delivers native 16:9 aspect ratio picture.
If you connect the projector to a High Definition TV (HDTV) tuner, the following standards 
are supported:
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.

Connecting an S-Video source device
Examine your Video source device to determine if it has an unused S-Video output socket 
available: 
• If so, you can continue with this procedure.
• If not, you will need to reassess which method you can use to connect to the device.
To connect the projector to an S-Video source device:
1. Take the (optional accessory) S-Video cable and connect one end to the S-Video 
output socket of the Video source device.
2. Connect the other end of the S-Video cable to the S-VIDEO socket on the projector.
3. If you wish to make use of the projector (mixed mono) speaker, take a suitable audio 
cable and connect one end of the cable to the audio output socket of the computer, 
and the other end to the Audio socket of the projector.
The final connection path should be like that shown in the following diagram:
• The projector is only capable of playing mixed mono audio, even if a stereo audio input 
is connected. See Connecting Audio on page 20 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.
• If you have already made a Component Video connection between the projector and this 
S-Video source device using Component Video connections, you need not connect to 
this device using an S-Video connection as this makes an unnecessary second 
connection of poorer picture quality. See Connecting Video source devices on page 20 
for details.
