    Default DVI to SVideo

    Hi,

    Does anyone know of a solution to convert DVI to SVideo?

    I have a customer who has a PC with DVI-out and wants to connect it to a plasma that only has SVideo...

    Thanks

    Trevor

    HI Trevor,

    Dont know of any DVI to S-Video converters, and I would imagine that if you find one it would be very expensive.

    Does the Plasma not have a VGA input ? If so, you should be able to output VGA from the DVI socket using an adapter (unless it is purely digital DVI).

    I would suggest that the cheapest option would be a new Video Card for the PC that has an S-Video output.

    Regards

    Its designed for a mac tho so not sure if it will work

    It seems very cheap so I would guess it is an adaptor rather than converter. (By cheap I dont mean nasty, just inexpensive!)

    I suspect the MAC is already capable of PAL S-Video and Composite and that these are present on some of the pins of the DVI connector with this lead simply performing a change of physical presentation.

    The X-Box changes the signals presented on some its connector pins in response to conditions on other pins so different leads give different signal outputs.

    From the old MACs' that I used to work with, they all had Video outputs when it was almost unheard of on a PC so I suspect their chipsets are video ready.

    I guess the only way to be sure it to buy one and see if it works on a PC

    Be interesting to find out... you are hereby nominated as official AutomatedHome guinea pig

    I would volunteer but dont have a graphic card with DVI outputs.

    Just noticed this bit....

    Important:Requires Mac mini or Power Mac G5 with DVI port.

    ... so may not work on a PC as I suspected.

    Need a guinea pig with a MacMini and a PC so they will still be able to use it. Step forward Mr McCall

    I'd imagine (maybe wrongly) that DVI would be a "standard" so the converter for the Apple would work elsewhere too? My DVI LCD works on a Mac or a PC.

    If you'd like to send me one I'll test for you

    DVI is a standard and as you say, your DVI monitor works with MAC or PC.

    What I was trying to get across is that the "smarts" might be inside the MAC and that when the adapter cable is connected the MAC outputs a different type of signal through the physical DVI connector.

    From the Apple store webpage....

    "When connected to the DVI port of your Power Mac G5 or Mac mini and to the S-video or Composite connections of these video devices it automatically outputs the PAL video timing format. The Apple DVI to Video Adapter is designed to work with the DVI port on the Mac mini and Power Mac G5 systems only."

    ...which makes me think it wont work on a PC.

    As I mentioned about the X-Box. It has a single output connector and depending on the type of cable you connect it changes the signals that appear on the pins. The cable then takes those signals and presents them on the appropriate type of connectors.

    I think what you need, is a DVI-I (not DVI-D) to VGA adaptor as supplied by most graphics card, then a VGA to S-Video adaptor, which you can find cheap on eBay.

    Like this one:

    Converting DVI analogue to S-video is easy like this, but to convert DVI digital I have no idea...

    That doesnt convert anything !!!!

    Its just an "Adapter Cable"

    Read the description more closely.....

    "It will work with VGA cards that has TV-Out function capability through the VGA connector."

    That means the Graphics card already produces S-Video and Composite but delivers it via the VGA connector instead of Minidin and Phone. The cable merely changes the physical presentation NOT the electrical presentation.

    Okay sorry my mistake I thought every modern graphics card has S-video signal through VGA.

    At least my Matrox Parhelia, G400, and Sapphire 9200 have...
