Interesting. My brother has a desktop video card (an Nvidia one, but I
didn't ask what exact card it is) with S-Video output, and he plugged
it into the same TV via the same cable as the laptop had been using.
According to xrandr, resolutions went up to (I think) 1024x768, but he
saw some oddities, which could have been caused by a stretching down.
I never thought to check the definition of S-Video, as I thought
(naively) that Windows was being honest when it told me it was running
it at 1024x768.

Thanks for the response. The silence was a little worrying - I was
afraid nobody here had ever used S-Video with old hardware, and that
I'd be completely on my own.
