Connecting to Video source devices
You can connect the projector to any of the following video source device\
 with an output jack:• HDMI
•  Component video
•  S- video
•  Video (composite video)
Only 1 of the aforementioned connection methods is required to connect t\
he projector to 
the video source device. However, different connection methods would provide a different 
video quality. The connection method selected would be determined by the presence of 
matching jacks on the projector and Video source device:
Best	video	quality
HDMI is the best video connection method available. If the source device\
 comes with 
HDMI jacks, you will be able to acquire uncompressed digital video quali\
ty.
Please refer to “Connecting to HDMI devices”  for details on how to connect the projector to 
HDMI devices.
If you don’t have any usable HDMI source, the next best video signal \
would be Component 
Video (not to be confused with Composite Video). Digital TV tuners and DVD players are 
provided with Component Video output sockets. If your device includes Component Video, 
then this would be your primary choice of connection to the (composite)\
 video.
Please refer to “To connect the projector to a Component Video source device:”  for details 
on how to connect your projector to Component Video devices.
Better	video	quality
S-video method provides slightly better simulation video compared to sta\
ndard composite 
videos. If the video device is provided with both composite video and s-\
video output jacks, 
you should try to choose S-video connection first.
Please refer to “To connect the projector to a S-Video source device:”  for details on how to 
connect your projector to S-video devices.
Least video quality
Composite Video is an analog video and will result in a perfectly acceptable, but l\
ess than 
optimal result from your projector, being the least video quality of the available methods 
described here.
Please refer to “Connecting to composite video source devices”  for details on how to 
connect your projector to composite video devices.
Connecting audio
The projector includes built-in dual-channel speakers that is designed t\
o provide basic 
audio functionality accompanying data presentations for business purpose\
s. It is not 
designed for, nor intended for stereo audio reproduction use as might be expected in\
 home 
theater or home cinema applications.

Connecting to HDMI devices
Use an HDMI cable to establish a connection between the projector and HD\
MI device.
1. Connect one end of the HDMI cable to the HDMI output jack on the video d\
evice.
2.  Connect the other end of the cable to the HDMI signal input jack on the \
projector.
  In the unlikely event that the projector is connected to a DVD player vi\
a the projector’s HDMI 
input	and	the	projected	picture	displays	wrong	colors,	please	change	the	color	space	to	 YUV.	
See “Changing HDMI input settings”  for details.
To connect the projector to a Component Video source 
device:
Examine your Video source device to determine if a set of unused Component Video 
output sockets is available:
• If so, you can continue with this procedure.
•  If not, you will need to reassess which method to use to connect to the \
device.
1.  Take a VGA (D-Sub) Component adapter 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 end of the VGA (D-Sub) Component adapter cable (with the D-Sub type 
connector) to the COMPUTER IN1/IN2 jack on the projector.
  If the selected video image is not displayed after the projector is turn\
ed on and the correct 
video	source	has	been	selected,	check	that	the	Video	source	device	is	turned	on	and	operating	
correctly. You must also check that the signal cables have been connected correctly.
To connect the projector to a S-Video source device:
Examine your Video source device to determine if an unused S-Video output socket is 
available:
• If so, you can continue with this procedure.
•  If not, you will need to reassess which method to use to connect to the \
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.
  If the selected video image is not displayed after the projector is turn\
ed on and the correct 
video	source	has	been	selected,	check	that	the	Video	source	device	is	turned	on	and	operating	
correctly. You must 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,	an	S-Video	connection	will	not	be	
required as this is an unnecessary second connection of poorer picture q\
uality. See 
“Connecting to Video source devices” for details.

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 proj\
ector.
  If the selected video image is not displayed after the projector is turn\
ed on and the correct 
video	source	has	been	selected,	check	that	the	Video	source	device	is	turned	on	and	operating	
correctly. You must 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 to Video source devices” for 
details.
Audio playback with the projector
During demonstration, you may use the projector (mixed dual channel) s\
peakers or 
connect separate sound systems with sound amplification functions to the  AUDIO OUT 
sockets on the projector.
If you have a separate sound system, you should connect the audio output\
 of your Video 
source device to this sound system instead of the mono audio input on th\
e projector.
