    By trying "that" I am assuming you tried a S-Video to composite adapter?

    And what type of video card do you have in your laptop?

    AVGeek, SVideo != Composite. Without a converter, SVideo inserted directly into a composite input will show up black and white.

    Not if you wire it right.

    I work with composit, Y/C , RGB RGBS and RGB Hs Vs Alll day long.

    I have adapters that work color on one unit , and b/w on another, it all depends on the wiring of the component.

    In any case, you CAN get a color signal from S-video to composit. It just might take some tweaking.



    Your best bet is to short 3 & 4 tegether and connect to the center pole of the rca or tip. then short 1&2 and connect to ground.

    sometimes, I short 1 & 4, and then go 3 to tip and 2 to ground.

    Its low voltage, so playing around wont hurt. check here for full specs http://www.vjcentral.com/faq/show/1049

    gizmomkr, if I could kiss you, I would. I have a presentation coming up soon and I was going to use a TV that only had composite/coax in and I could only get it to show B&W. The RCA to SVideo adapter I was using didn't have pin 3 connected to anything.

    Glad you're on this board.

    Wow - glad to help, but please - no kisses.

    Pin 3 is lumenance, pin 4 is chrominance. Svideo is higher quality because it gives a seperate path for both chanels of video.

    Taking chroma or luma seperately will give b&w at best, and sometimes even less. Combining the two back into one chanel will give you a color image.

    You might need to insert a 470pF(that's "pico farad") ceramic capacitor on the signal line to pin 4 on the svideo connector. It depends on your card's chipset, but this usually works with every card.
