7 pin S-video to 4 pin S video Help!

[NotoriousTAT6]

SO I have this MSI geforce 4 ti4200, it has an s video tv-out with a 7 pin connector. The problem is that the industry standard is pretty much 4 pin all around the board... Does anyone know where I might be able to find some converter or connector to use my tv-out? Thanks in advance for your help.

A regular 4-pin S-Video cable should work fine... It should only use 4 pins for S-Video. The other (2) pins are for composite video (with the bundled adapter), can't remember what the 7th one is.

Anyways, just get a regular 4-pin cable if you want to use S-Video.



Here's a link with an explanation: http://www.hut.fi/Misc/Electronics/circuits/svideo2cvideo.html

Generally the four pins on those 7-pin connectors on the same places as the standard four pin S-video connector have practcly always the same fuctionality as those pins in S-video connector. The other three pins can have then some extra signals which are not part of S-video (usually some pins of those carry composite video and some control signals, but the use of those three extra pins vary quite much). So if you encounter 7 pin connector for S-video, then forget the three center pins... just use the four on the standard positions. The circuit shoudl work with those connectors as well.
