How to make s-video --> cinch and/or s-video --> scart cable

Hi! Are you looking for s-video --> cinch or s-video --> scart cable? So you are right on this page.

What is s-video?

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.

What do you need?

  1. S-video connector (also called MiniDin 4-pin)
  2. Cinch connector or scart connector (it depens on your TV's input)
  3. Some shielted wires
  4. Small switch

There is how to connect the wires:

Installation step-by-step: (ATI mobility step-by-step with pictures click here)

Well. You have done yours cable and what else?

  1. Connect one side of the cable to the s-video out and...
  2. ...the second side to the TV or video. The chrominance swith must be off. Go to your graphic card setting (control panel). {ATI mobility: right click on your desktop and choose properties. Click on the settings card and then the third button (specify? - I don't know because I have Czech Windows :-)) and it opens graphic card control panel. Take screens and switch the TV on.}
  3. When you see b/w image on your TV, this is the right time to switch the chrominance switch on.
  4. If you were succesful you can see color image on your TV's screen. Wow.

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.

Need an audio cable?

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.

What do you need?

  1. MiniJack connector
  2. 2x Cinch connector or scart connector (only one for video and audio signal)
  3. Some double-line shielted audio cable

What else?

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.
