I've seen the same problem running s-video out to s-video in. I fixed it by
putting an A/V switching receiver in between the computer and the TV. I
think the problem has something to do with what the card senses is connected
to it. If it thinks it's composite but it's connected to s-video or vice
versa, then you end up with a monochrome picture.

Hello,

I've tried S-video output on Asus GF 5900.
I used the cable "S-video - Composite" which came with video card.

While loading winXP I can see XP logo in color but
when login window appeared there is already no color picture
(possibly nvidia driver is loaded). Only black and white picture
afterwards.

Any help will be really appreciated.

Thanks a lot,
Sergej
