Connecting a computer
1. Take a VGA/HDMI/USB-C cable and connect one end to the computer.
2. Connect the other end of the cable to the COMPUTER IN/HDMI 1/HDMI 2/USB-
C 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 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:
Best video quality
The best available video connection method is HDMI. If your source device is equipped
with an HDMI socket, you can enjoy uncompressed digital video quality.
See "Connecting an HDMI device" on page 16 for how to connect the projector to an 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 17 for how to connect the
projector to a component 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 17 for how to connect the
projector to a composite Video device.
Connecting audio
You can make use of the projector speaker in your presentations, and also connect separate
amplified speakers to the Audio Out socket of the projector. The audio output is controlled
by the projector Volume and Mute settings.
Connecting an HDMI device
You should use an HDMI cable when making connection between the projector and HDMI
devices.
