Connect your computer to a TV
To
connect your computer to a TV, your computer needs to have an output port that matches one of the input ports on
your TV.
What you'll need if you have an HDTV
Because almost every computer has an output port, you can use a
cable to connect your computer to your high-definition television (HDTV). Most computers
have a VGA output port (so using VGA cables is very common). Others have
Digital Visual Interface (DVI), high-definition multimedia interface (HDMI), or
component video output ports, which all require different kinds of cables.
The following scenarios show you how you can connect a computer

What you'll need if you have a standard-definition TV
Most standard-definition TVs support only composite video or
S-Video connections. If your computer supports one of these, you might be able
to connect it to your TV. However, both of these connection types will result
in displays that are not as sharp as the results you get with an HDTV or with a
standard computer monitor.

Connect your computer to your TV
After you have the right cable, follow these
steps to connect your computer to your TV:
1. Turn
off your computer and position it within easy reach of your TV. Disconnect the
monitor, but leave the mouse and keyboard connected.
2. Connect
the appropriate video cable from your computer's output to your TV.
3. Turn
on your TV and set it to the input that matches the output on your computer.
You might need to refer to the user's guide included with your TV for
instructions on how to do this.
4. Turn
on your computer.
You should see Windows displayed on your
TV. If the screen looks stretched, or part of the screen seems cut off, you
probably need to adjust the screen resolution in Windows.
For more information, see Getting the
best display on your monitor.
If you can't see Windows on your TV, you
might need to reconnect the computer to your monitor and adjust the screen
resolution before you connect to your TV.
Notes
•
Cables
for VGA, DVI, and component video don't support audio signals. However, HDMI
cables do support audio signals, but not all HDMI-enabled video
cards support audio.
If your HDTV has an audio input, you might be able to connect a separate audio
cable from your computer sound
card directly to the
TV. Otherwise, you'll need to connect the audio signal to a different device,
such as external computer speakers or your home stereo system. For more
information about sound cards, see Sound cards: frequently asked
questions.

If
your computer doesn't support the type of video connection you need, then you
might be able to install a new video
card that has the
right connection.
