I have an older laptop with an s-video output which I needed to hook up to a large screen TV for karaoke. I was surprised to find the TV had every imaginable video input option except s-video. This little adapter is a perfect solution. I have only used it for karaoke lyrics so I'm not in a position to comment on picture quality etc., but it works perfectly for my needs. I plug the adapter into the laptop and run an RCA cable from it to the TV.
