Trying to connect an old Lenovo 0768 to a crt, there is an s video out and vga out on the laptop, however, there is no option to send the signal out the s video, it keeps telling me there is no projector connected. So presumably the only output is the VGA, so how I can tell if the S video is an input?

And do cables such as VGA to RCA/s video exist?

I did have a search and the results were more modern. Not quite as easy as my even older Toshiba laptop!
