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:
HDMI
Component Video
(through RGB input)

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 not designed for, nor
intended for stereo audio reproduction use as might be expected in 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.
• 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 smart devices

The projector can project the content directly from a smart device by using a wireless dongle.
HDMI wireless dongle (e.g. BenQ QCastMirror)
• Connect the dongle to HDMI 1 or HDMI 2 and USB TYPE-A ports on the projector and switch
the input signal to HDMI 1 or HDMI 2.
