Using the Gateway 205 Projector
Cable Description
Composite video cable. Use this cable to
connect a video component, such as a DVD
player or VCR, to the projector.
The video signal is carried through a single
video (yellow) connection.
The two additional connectors carry the left
(white) and right (red) channel audio signals
to an audio receiver.
S-Video cable. Use this cable to connect a
video component, such as a DVD player or
VCR, to the projector.
The video signal is split into two signals,
black-and-white and color. This type of cable
produces a better picture than the
single-connector from the composite video
cable.
This cable provides no audio output.
10
Component video cable. Use this cable to
connect a video component, such as a
progressive-scan DVD player or satellite
dish, to the projector.
The video signal is split into three signals,
one black-and-white and two color. This type
cable provides the best possible picture.
This cable provides no audio output.
