Understanding Video Connections
Your Micro Chip Display Projection TV has four types of standard video connections.
You should use the best connection available to get the best display. For example, if
your DVD player supports a component video connection, connect the DVD Player
to your Micro Chip Display Projection TV using component video instead of
composite video or S-Video.
Connection Cable and Description
Quality Connector
Base Coaxial (RF). The video and audio signals are
both carried in one cable (the other three
connection types only handle video, and
require separate connections for sound).
Coaxial is the only way to connect an antenna
to your RPTV.
Good Composite. The video signal is carried through
a single “pin.” This connection method is the
one that is most commonly found on devices.
Better S-Video. The video signal is split into two
signals, black-and-white and color. Text
displayed on-screen through this connection
will be noticeably sharper than composite or
coaxial (RF).
Best Component. The video signal is split into three
signals, two colors, and one black-and-white.
Use component video to take advantage of the
superior picture provided by signal such
sources as HDTV and progressive DVD.
