Using TV as 2nd monitor

[sbga]

Hi, I am trying to use my TV to view AVI files on my laptop and I can't get
it to work. I am using a s-video cable that converts to 3 red, green, and
blue plugs.. and am using a standard RCA cable to connect from that to my
TV.. my TV does have the red, green and blue plugs in the back. However when
I hook it up I get nothing, and I have set in control panel to use the 2nd
monitor. The video card in my laptop is a ATI radeon xpress 200 series. Do I
need to get a program like ATI Catalyst? is this even possible?

BTW, the adapter cable I am using came with a nvidia video card that I got
for my desktop, but I am trying to use it with my laptop so I can view video
on my TV. Help appreciated

Did you set the Television to the proper input ( Channel ) ? Usually
you just channel tune below Channel 2 to move through the alternate
input(s).

Yes, I flipped through all the video input channels and nothing showed up

Your notebook has a Fn+Key press that toggles the Video output from
the Internal LCD to external. You may need to determine your key press
and try toggling the video output.

The "red, green and blue" plugs are component video. You said you went
through the video channels, but maybe there's something you have to
switch to get the TV to listen to the component video input?

I looked on the remote for the TV and couldnt find anything that sounded like
it was associated to that.. and also pressed a bunch of button just for the
heck of it

That worked. However the display on my TV is only in black and white
