Connect with the monitor
If you want to play the display on the monitor and screen at the same time, you can use the
following instructions to use the VGA cable to connect the computer output socket on the
projector to the external monitor.
Connect the projector to the monitor
1) Connect the projector to the computer, as described in the previous chapter.
2) Use the appropriate VGA cable and connect one end of the cable to the D-sub input socket
of the video display. If the monitor is equipped with the DVI input port, connected the DVI end
of the VGADVI (A) cable to the DVI input socket of the video display.
3) Connect the other end of the cable to the computer output socket of the projector.
You can connect the projector to a variety of video source devices that provide one of the
following output sockets:
1) HDMI
2) S- Video
3) Video(composite video)
You only need to use one of the above connection methods to connect the projector to the
video signal source device but each method provides a different video quality. Which way to
choose depends on whether the projector has the following terminals on both the video
source device and the projector.
Best video quality
The S-Video method provides analog video that is better than standard composite video. You
can choose to use the S-Video option if both a composite video and an S-Video output source
are available on the video source device. For more information about how to connect a
projector to an S-Video source device, please refer to the "connecting S-Video device"
chapter below.
Minimum video quality
Composite video is analog video, although it is not the best quality on your projector, but it is
also the lowest video quality of all available methods described here. Please refer to the
"connecting Composite Video Source Settings" chapter below for more information about how
to connect projectors to composite video source devices and other details.
The projector has a mono loudspeaker designed to provide basic audio functionality. And it is
only for a demonstration for commercial. They are not designed for stereo audio reproduction

20/ 33
or for home theater. Any stereo audio input (if provided) is mixed through projector
loudspeakers to produce commonly used mono audio outputs.
The following table describes the sources of sound when connecting to different signal
sources:
Input signal source
Computer input
S-Video or Video input
This projector can play the
sound source bellow
Computer audio input
AV audio input
This projector also provides separate MIC input, external MIC input for computer input or
video input (including S- video). In the meantime, the corresponding audio input will not be
able to play the sound.
Connect HDMI equipment
Check the video source device to determine if it has an unused HDMI output socket available.
If so, you can continue this program. If not, you will need to reevaluate the methods available
to connect to the device.
Projector connected to HDMI signal source equipment
1) Use the HDMI cable (which is not in the projector's wrapper) to connect one end to the
HDMI output socket of the HDMI source
2) Connect the other end of the HDMI cable to the HDMI input port HDMI1 or HDMI 2 of the
projector. And through the remote control or button selection of the corresponding display
channel.
Check the video source device to determine if it has an unused S-Video output socket
available. If so, you can continue this program. If not, you will need to reevaluate the methods
available to connect to the setup.
Projector connected to S- Video Source equipment
1) Connect one end to the output socket of the S-visual frequency source using an S-Video
cable (which is not in the projector's packaging)
2) Connect the other end of the S-Video cable to the S-Video input port of the projector.
Connect composite video equipment
Check the video source device to determine if it has an unused composite video output jack
available. If so, you can continue this program. If not, you will need to reevaluate the methods
available to connect to the setup.
