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 notebook's documentation to find your notebook's
key combination.
EN-19
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
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:

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 jac
k 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
VGA/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.
