    Hello, If any one can help, that would be great..
    I want to hook my cpu up to my tv via s-video but on the back of my cpu, the s-video dosent match up to the cable. On my tv its a normal s-video plug. Do I need a plug/converter?? if so where can I find one. I went to Future Shop and they had no idea,, ty for your help..Much Appreciated

    Well it sounds like you're talking about the 15 pin analogue output.

    Well I wouldn't shop there again, as it seems their future is looking bleak if they can't direct you..............

    This cannot be connected directly to the s-video due to the configuration of how it is transmitted.......different signals.

    You will either need a Graphics card that has an s-video output/software to convert the analogue signal in order to transmit over s-video or indeed a VGA to S-video adapter.

    Something like the following http://www.svideo.com/vgatotv.html

    Have a look around, as prices do vary, the good thing about these converters is that they do not drain PC resources as all the conversion is taken place outside the PC, so if you have a low specification machine this would be the way to go.

    However a graphics card would be easiest way to go as there is minmum configuration and connections required.

    Hope this helps..............

    S-Video
    (Analog) All video signals are transmitted through two miniature 75-ohm coaxial cables that are usually joined into a single cable and terminated with 4-pin connectors. S-video improves video quality beyond composite video (above) because the separate brightness and color signals are kept separate rather than combined into the composite signal, and this reduces encoding and decoding and therefore signal loss. However, the color signal must be further decoded and demodulated into two other components to separate the RGB (red-green-blue) signals. S-video provides better video quality than composite video unless s-video is adapted to composite video.

    RGB Video
    (Analog) Often confused with component video (above). All video signals are transmitted on three, four or five 75-ohm coaxial cables with either RCA, BNC or 15-pin connectors. RGB video is often confused with component video (above). Within RGB cables, there are three sub types, depending on the number of connections:
    RGB or RGSB
    Includes three separate connections: Red, Blue, and Green+Synchronization. *Often confused with component video.*
    RGBS - Includes four separate connections: Red, Blue, Green, and Synchronization.
    RGBHV - Includes five separate connections: Red, Blue, Green, Horizontal Synchronization, and Vertical Synchronization.
    VGA/SVGA/XGA - Includes one 15-pin connector (some with three rows of pins and some with two rows of pins).

    Unless the adapter contains the components to carry out the modulation and demodulation I doubt it.

    Thats, if I am on the right track anyway, I am asuming that you are trying the following:

    Ah, got you now.......

    7 pin S-video from your Graphics card to 4 pin S-video on your TV.

    This is what you mean I think

    Found here http://www.svideo.com/7pinxclaim.html

    These are common, just put a search in google along the lines of 7 pin s-video to 4 pin s-video adapter and you should get plenty of hits.

    Tv shops and the like should sell these quite commonly.

    Hope this helps...............
