Recently I wanted to see how well TV output on my card is and watch a few movies on the big screen. Composite was working fine, but I had a spare S-Vid and figured I'd use that.

Anyway, I plugged in the S-Vid cable and I only got black and white on the screen. I checked settings and such and couldn't find anything to change. Unplugged the S-vid and plugged the composite in, worked fine. Tried the S-vid on a different s-vid input on my TV, same thing.

Any suggestions?

The s-video cable has two wires pushing data to the TV. One is the color information (chroma) and the other is the brightness (luma) information. Your cable is somehow dropping the color information and is only passing the luma. What card are you using? Does the video card have an s-vid and a composite output on it or are you using some sort of adapter to get the two signals?

It's a Gainward GeForce 4 Ti4600 Golden Sample (VIVO) card. It uses a breakout cable with a composite video out, S-Video out, composite video in, and S-Video in tethers.

I know it's not the TV, as my DVD player used to be hooked up to the S-Video of the TV.

It may be that the cable is not passing the chroma signal to your s-vid out connector or maybe the card is faulty. It would be kind of hard to see if it is the cable or the card so I would just exchange it if its under warranty. If not, then you are kind of screwed. Could you get ahold of another cable to test it?

Another thing is that maybe the "spare" s-vid cable has faulty connectivity. If you have a multimeter, you can test the connectivity of the cable's leads or just hook it up with your dvd player to the TV (or is that where the cable is from).

You might want to check your output format and video output format.

IIRC, I had a similar problem, and tweaking the output formats was what was needed.

What drivers do oyu have installed?

Sorry I haven't tested it out yet... I haven't had issue to hook my computer up to the TV lately.

In any event, stokey - it is the same cable that was hooked up to the DVD player and was working fine. Sparkz, there are no settings to change.

Oops. I entered without typing... Anyway, where can I check this output format and video output format?

Thanks
