29
TVs (and VCRs) have a Composite video input, in
which case you can use an S-Video-to-Composite
adapter. If your TV has cable input only, you can
connect your card to your TV through your VCR or
an RF modulator (available in most electronics
stores).
Connecting Your S-Video Out to a TV or VCR
1 Turn off your PC and your TV (or VCR).
2 Ensure your card was installed correctly as per
the Getting Started Guide.
3 Determine if your TV (or VCR) has an S-Video
or Composite video connection.
4 Looking at the back of your PC, locate your S-
Video Out. Using an S-Video cable (or S-Video-
to-Composite adapter), attach one end of the
cable to your graphics card and the other to your
TV (or VCR). Refer to the illustration for further
help.

TV display only, make sure that you have the TV
display feature enabled.
You can set your display resolution as high as
1024x768. However, higher resolutions will result in
a virtual desktop. If a TV is your only display device
34
and a higher mode is selected, the display on your
TV will disappear.
Using Games and Applications
Some older games and applications may program
your RADEON™ card directly, to run under a
specific display mode. This may cause your TV
display to turn off automatically or become
scrambled (the PC monitor will not be affected).
Your TV display will be restored once you exit the
game or if you restart your PC.
