Hi,

I have an S3 savage4 (I think that's right) graphics card, which has an s-video output on it. I've tried connecting this to the scart socket on the TV, but it's not right. I've tried it with two s-video leads, two s-video-scart adapters and two TV's!! On one TV the output was black and white, and on the other it was all over the place, flickering and everything in three places at once. The wikipedia article I read suggests that it's probably because both of the TV's are quite old.

I tried a couple of hardware hacks I found on the interweb, but neither of those made a difference. (one was connecting two pins on the s-video, and the other was connecting two pins on the scart. Probably both did the same thing...


Anyone got any more ideas, 'cause I'm fresh out, and my wife wants me to get the computer screen out of the living room:O
 
There are a few ways in which a tv can accept a signal.

  • RF (like from the roof aerial) Sound and Video
  • Composite/Composite SCART (the yellow lead or scart). This is video alone.
  • Component S-Video/S-video SCART. S-Video is video only which is split into Intensity and Colour
  • Component RBG/RBG SCART. Video only and split into Red, Green and Blue.
  • Component. YPbPr Video only and split into Luma, Blue and Luma and Red and Luma. HD and Digital form too.
  • DVI and HDMI. Digital and HDMI has sound too.
By the sounds of it you have a SCART adapter which is using the S-Video signal and your TV doesnt support S-Video. You can get adapters which turn the S-Video into a composite signal which will work on all TVs with SCART.
