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 VGA1-IN/YPbPr or 
VGA2-IN/YPbPr signal input socket on the projector.
Important
„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 notebooks documentation to find your notebooks 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 VGA 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 18.
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 VGA OUT socket on the 
projector.
Important
„The VGA OUT output only works when VGA1-IN/YPbPr or VGA2-IN/
YPbPr is made to the projector.

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 avail-
ability of matching terminals on both the projector and the Video source
device as described below:
Note
„Not all models have HDMI input jack, please check your projector before connecting

Connecting an HDMI source device
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.
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) to HDTV (RCA) 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 cable (with a D-Sub type connector) to the 
VGA1-IN/YPbPr or VGA2-IN/YPbPr socket on the projector.
Important
„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.
