Connecting a computer or monitor
Connecting a computer
The projector provides two VGA input sockets that allow you to connect them to both
IBM® compatibles and Macintosh® computers. A Mac adapter is needed if you are
connecting legacy version Macintosh computers.
To connect the projector to a notebook or desktop computer:
1. Take the supplied VGA cable and connect one end to the D-Sub output socket of the
computer.
2. Connect the other end of the VGA cable to the COMPUTER IN1 or COMPUTER
IN2 signal input socket on the projector.
Many notebooks do not turn on their external video ports when connected to a projector.
Usually a key combo like FN + F3 or CRT/LCD key turns the external display on/off. Locate a
function key labeled CRT/LCD or a function key with a monitor symbol on the notebook. Press
FN and the labeled function key simultaneously. Refer to your notebook's documentation to
find your notebook's key combination.
Connecting a monitor
If you want to view your presentation close-up on a monitor as well as on the screen, you
can connect the MONITOR OUT signal output socket on the projector to an external
monitor with a VGA cable following the instructions below:
To connect the projector to a monitor:
1. Connect the projector to a computer as described in "Connecting a computer" on page
13.
2. Take a suitable VGA cable (only one supplied) and connect one end of the cable to the
D-Sub input socket of the video monitor.
Or if your monitor is equipped with a DVI input socket, take a VGA to DVI-A cable
and connect the DVI end of the cable to the DVI input socket of the video monitor.
3. Connect the other end of the cable to the MONITOR OUT socket on the projector.
The MONITOR OUT output only works when COMPUTER IN1 connection is made to the
projector.
13
Connecting Video source devices
You can connect your projector to various Video source devices that provide any one of the
following output sockets:
• HDMI
• 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 HDMI. If your source device is equipped
with a HDMI socket, you can enjoy uncompressed digital video quality.
See "Connecting an HDMI device" on page 15 for how to connect the projector to a HDMI
source device and other details.
If no HDMI source is available, the next best video signal is Component video (not to be
confused with composite video). Digital TV tuner and DVD players output Component
video natively, so if available on your devices, this should be your connection method of
choice in preference to (composite) video.
See "Connecting a Component Video source device" on page 15 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 16 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 16 for how to connect the
projector to a composite Video device.
Connecting audio
The projector has one 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 theater or
home cinema applications. Any stereo audio input (if provided), is mixed into a common
mono audio output through the projector speaker.
If you wish, you can make use of the projector (mixed mono) speaker in your presentations,
and also connect separate amplified speakers to the Audio Out socket of the projector. The
audio output is a mixed mono signal and controlled by the projector Volume and Mute
settings.
14
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 output only works when a signal source is connected to the projector.
• When an audio cable is connected to the AUDIO OUT port, the projector’s speaker will be
muted.
Connecting an HDMI device
You should use an HDMI cable when making connection between the projector and HDMI
devices.
To connect the projector to an HDMI device:
1. Take an HDMI cable and connect one end to the HDMI output port of the video
device.
2. Connect the other end of the cable to the HDMI input port on the projector.
The projector is only capable of playing mixed mono audio, even if a stereo audio input is
connected. See "Connecting audio" on page 14 for details.
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 VGA (D-Sub)-Component 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 VGA (D-Sub)-Component adaptor cable (with a D-Sub
type connector) to the COMPUTER IN1 or COMPUTER IN2 socket on the
projector.
• The projector is only capable of playing mixed mono audio, even if a stereo audio input is
connected. See "Connecting audio" on page 14 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.
15
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 an 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.
• The projector is only capable of playing mixed mono audio, even if a stereo audio input is
connected. See "Connecting audio" on page 14 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 14 for details.
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 socket on the projector.
• The projector is only capable of playing mixed mono audio, even if a stereo audio input is
connected. See "Connecting audio" on page 14 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.
• You need only connect to this device using a composite Video connection if Component
Video and S-Video inputs are unavailable for use. See "Connecting Video source devices"
on page 14 for details.
