S-video (4-pin) is used with some graphic cards as video output. But no all TVs and videos have s-video input. I was in many shops but they said me that it is impossible connect directly s-video out to cinch-in on the TV or that this cable does not exist. Some graphic cards have s-video --> cinch reduction. But this reduction does not work with some graphic cards (for example with ATI mobility in my Compaq Evo N1015v) because the graphic card can't recognize that the TV is connected and it is not allowed switch the TV on on the control panel. I was angry because I do not have a TV with s-video in. But there is a simple way how to override the TV detection and succesfully connect your graphic card with s-video directly to cinch-in or scart. In the s-video (4-pin) are separately two signals. Luminance and chrominance. This is better for quality as cinch where are this signals in one wire. Yes. You can connect directly luminance and chrominance. But this works only with some graphic cards but some of them cannot recognize the connection. How to solve this? There is a simple way. First - you must connect only luminance signal from the s-video to cinch. The graphic card recognizes that TV is connected and you can switch the TV on in the control panel. Hmm. You can see black&white screnn. This is the right time to connect the chrominance signal to cinch. And the image is color. You must do this every time you connect the graphic card to the TV. You can solve the connection/disconnection of chrominance signal with some small switch which is inbuilt in one of the connectors or which is on the wire. For experiments you can connect the chrominance signal wire by hand to the cinch connector which is without covering.
Well. You have done yours cable and what else?
So you can play films from your computer now. But (ATI mobility) when you'll play films from your notebook you must set the TV as primary screen! because the card is able show the movies only on the primary screen. On the second you can see only black screen on the place where is the player's window.
Well. You have video cable. But I think you will hear the sound on your TV
too. Here is how to connect the Minijack output from your soundcard to the
TV.
If your TV or video has cinch inputs, you need Minijack --> cinch stereo cable.
You can buy it or you can do this cable yourself. How to connect the wires
is on the picture.
If your TV or video has scart input, you must connect the Minijack out to
the pins in the scart connector.
That's all. Enjoy videos and pictures from your graphic card on your TV and
sound from your souncard on your TV too. I've tested this wiring on my Compaq EVO
N1015v notebook and it works fine. Don't forget send me
mail and write me if you were succesful.
