Connecting Your Computer to a TV and Adjusting Display Settings
A DVI connector allows you to connect an external
DVI-compatible monitor, such as flat-panel
monitors or TVs. DVI connectors are available for
DVI-D (digital only), DVI-A (high-resolution
analog), and DVI-I (digital and analog).
DisplayPort allows you to connect a computer
and a home-theater system. For more
information see "DisplayPort™ - Features and
Benefits
" on page 56 and "DisplayPort™ " on
page 327 .
A HDMI connector allows you to connect an
external HDMI-compatible monitor or TV. HDMI
transfers uncompressed video and multi-channel
audio over a single cable.
NOTE:
DVI and HDMI are compatible and there are
converter cables available. If your computer does not
have an HDMI connector and your TV does not have
a DVI connector, use your computer’s DVI connector
with a DVI/HDMI converter cable to connector to the
HDMI port on the TV.
You will need to connect a separate cable for audio
because the DVI connector does not transmit the
audio signal.
A VGA connector allows you to connect an external
VGA-compatible monitor.
Connector Description/Function
NOTE:
DVI-A, DVI-D, and DVI-I connectors are non-
interchangeable. Cables for each are unique. Make
sure that you know which format your computer
supports.
