Some early personal computers used TV sets as
monitors because they came without monitors.
The images displayed were simple and of low
quality. Now, with the large quantity of video
available on the Internet, as well as the
introduction of high-definition television, it is
possible to connect your PC to your TV and use
them together as a digital media center. Here's
what you need to know.
Determine which video output port(s) your
PC has. There are several possible types;
your computer may have more than one.
A VGA port is roughly rectangular with
15 pins in three rows of five. It's how
most dedicated computer monitors are
connected to PCs. It looks like something
that would fit this:
An S-video port is circular with either
four, seven, or nine pins. It looks like
something that would fit this:
A composite video port is a circular jack,
usually color-coded yellow. It looks like
something that would fit this:
A digital video interface (DVI) port is
rectangular, with 24 pins in 3 rows of 8.
It is designed for high-definition
connections. It looks like something that
would fit this:
A high-definition multimedia interface
(HDMI) port resembles a USB port but is
longer and thinner. Available in PCs since
2008, it is also designed for high-
definition connections. It looks like
something that would fit this:
See which video input ports your TV has.
This will largely depend on whether your
TV is a standard-definition or high-definition
TV. Newer, especially flat screen TVs, are
likely to be high-definition, while older TVs
are likely to be standard definition.
Standard-definition TVs usually have
composite video or S-video ports;
however, the display will not be as sharp
as through your PC's regular monitor.
High-definition TVs may have VGA, DVI
and/or HDMI ports. VGA connections
provide an analog signal, while DVI and
HDMI connections provide a digital
signal of higher quality.
Get the right video cable to connect your
PC to your TV.
If your PC's output port is the same kind
as your TV's input port, get a cable with
the same kind of connector on each end.
If your PC's output port and your TV's
input port are different, you'll need an
adapter cable. Adapters are available to
convert DVI to HDMI or VGA to
composite video.
You can also get an
adapter cable to connect your computer's
USB port to your TV's HDMI port if
your PC has no HDMI port.
