Ati 8500 OEM S-Video Pinouts?

A standard 4-pin S-Video cable does work on this card but my TV doesn't support S-Video. There are 3 extra pins on the 8500's connector. Does anyone know if any of those pins carry Composite Video?

Now, I could build a cheap breakout circuit like <A HREF="http://www.hut.fi/Misc/Electronics/circuits/svideo2cvideo.html" target="_new">this one</A> but it degrades the signal. If the signal is already available then I would use that instead.

  1. Should be since I do have a <A HREF="http://andrewt1.tripod.ca/svideo_rca_adapter.jpg" target="_new">Svideo to RCA adapter</A> that I got with my GeForce 2 GTS Deluxe card. Stores should carry it, or if nothing else then order one from Asus.

  2. forgot to say that the picture is a 7 pin not the regular 4 pin s-video, it's just damn bad quality because my camera doesn't like it when I'm too close to something.

    not doing edit because then you might never notice it :P

  3. If you would have bought the Retail card, you would have gotten two adapters with it, a DVI to VGA for the second monitor port, and an ATI S-Video to Composite adapter dongle. You would have also got an S-VIdeo cable and a Composit cable. I would guesse that the combined value of these parts is around $40. Anyway, you can order a replacement dongle from ATI.

    What's the frequency, Kenneth?
  4. Uses an S-Video to Composite dongle?

    I guess that means the extra pinouts don't carry Composite video.

    Does the dongle appear to have room for a circuit in it?

    I wonder if it just has a capacitor like the circuit in my link.

    Anyway, it doesn't really matter. I don't have a big need to connect my computer to the TV I have now. When I replace the TV it will have an S-Video connector.

    Never really thought about the added value of cables with the retail 8500. At least I got an extra long S-Video cable with the OEM 8500.

  6. The dongle is actually just a connection for those three pins, like you said. Having the dongle available is a lot easier than wiring your own.

    What's the frequency, Kenneth?
