Connecting an HDMI source device
The projector provides a HDMI input jack that allows you to connect it to an HDMI 
source device like a Blu-Ray player, a DTV tuner or a display.
HDMI (High-Definition Multimedia Interface) supports uncompressed video data 
transmission between compatible devices like DTV tuners, Blu-Ray player and displays over 
a single cable. It provides pure digital viewing and listening experience.
Examine your Video source device to determine if it has a set of unused HDMI output 
jacks 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 HDMI source device:1. Take an HDMI cable and connect one end to the HDMI output jack of the HDMI 
source device.
2. Connect the other end of the HDMI cable to the HDMI jack on the projector.
• The HDMI cable (shown in this example) for connection your video output device is not 
supplied as standard.
• The Apple Digital AV Adapter can be purchased from www.apple.com
.

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:
1. Take a 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 jack of the multi-input cable.
3. Connect the other end of the multi-input cable to the PC/AV socket on the 
projector.
4. If you wish to make use of the projector speaker, take a suitable audio cable and 
connect one end of the cable to the audio output sockets of the Video source 
device, and the other end to the audio input sockets of the multi-input cable.
• When audio output jack is connected with the earphone or external speaker, the sound will 
not come out from the projector speaker.
• No sound will come out from the speaker or audio output jack if video signals are not input. 
Besides, the sound cannot be adjusted either.

Connecting a composite Video source device
Examine your Video source device to determine if it has a set of unused composite 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 composite Video source device:
1. Take a Video cable and connect one end to the composite Video output socket of 
the Video source device.
2. Connect the other end of the Video cable to the Video jack of the multi-input cable. 
3. Connect the other end of the multi-input cable to the PC/AV socket on the 
projector.
4. Connect the multi-input cable to the PC/AV socket on the projector.
5. If you wish to make use of the projector speaker, take a suitable audio cable and 
connect one end of the cable to the audio output sockets of the Video source 
device, and the other end to the audio input sockets of the multi-input cable.
You need only connect to this device using a composite Video connection if Component Video 
input is unavailable for use. See Connecting Video source devices on page 20 for details.

Connecting an iPhone/iPod device
To connect the projector to an iPhone/iPod device:
1. Dock your iPhone/iPod to fit the docking connector.
• See Playing files with iPhone/iPod on page 39 for details.
• Please note that if your iPhone is covered with a 
protective case, it may cause a bad connection 
between the iPhone and the projector. When you 
connect the iPhone to the projector and see the 
error message displayed on the iPhone screen, 
please remove the protective case and connect it 
again. (Because of poor connection and pin 
detection failure, it cause the command cannot be 
communicated successfully.)
The Universal Dock 
Adapter is not necessary 
for operation but does 
provide the best fit for 
your particular Apple 
product. You can 
purchase it from

• Do not turn off the product or pull a connected USB storage device out while the USB 
storage device is in use. Doing so may result in damage to the USB storage device or stored 
file. 
• Use a USB storage device which contains normal files. Abnormal files can cause a 
malfunction or the files may not play. 
• USB storages must be formatted in FAT16/FAT32/NTFS. FAT32 and NTFS are 
recommended for HDD (Hard Disk Drive).
• As the data in the USB storage device can be damaged, please back up important data to 
avoid loss. The user is responsible for data management. BenQ shall not be held liable for 
any data loss. 
• File tree in USB storage should be as simple as possible. Too many or too many layers of 
folders will result in lag of access time. 
• If an external memory device does not operate after you’ve connected it to the projector, 
try to connect it to a PC. If it still does not operate normally, contact the memory device’s 
manufacturer service center or related customer center.

Playing sound through the projector
You can make use of the projector speaker in your presentations, and also connect 
separate amplified speakers to the audio output jack of the projector.
The table below describes the connection methods for different devices, and where the 
sound is from.
• The selected input signal determines which sound will be played by the projector speaker, 
and which sound will be output from the projector when audio output jack is connected.
• There’s no need to connect to an audio input jack because the projector can play the sound 
from an HDMI, external memory and iPhone/iPod source device. However, you can connect 
to an external device to play the sound.
• USB display doesn’t support audio function.
