If you are getting B&W TV over a S-video connection it is because you have
let Vista automatically determine the connection interface insteead of
manually saying it is S-Video and in automatic mode it does not sense the
correct electircal impedence over S-Video from your display so it downgrades
the output to B&W.
Another possibility is that you have a faulty S-video cable or connector
which is only allowing the B&W signal to come through
I have the same problem as Rob, but I can't find the place to tell Windows
Vista to manually saying that the used output is S-Video. My videocard is an
nVidia and I use nVidia control panel to adjust the oputput, but still have
it in black and white.
Any suggestion?
I forgot to say that if I enter the BIOS, the image shows in colour, but when
Vista boots, it is in black and white, so it can't be becouse of the clable,
can it?
