I have had my HTPC running happily for just over a year now and I havent had any problems with anything TV-Out related. Today, I decided to put a new graphics card in the machine. I replaced the Ti4600 that was in it with a FX5950 Ultra.
Having messed around with the TV-Out for a couple of hours, trying all sorts of combinations and all sorts of driver versions I found 2 scenorios:
1. I managed to get a really sharp picture on the TV, but only in black and white. This was using a composite connection.
2. When I tried using just a s-video cable, the picture on the TV was in colour, but the picture quality was very "grainy". Nothing I tried seemed to have any effect on this.
Any advice on this problem would be grately appreciated. If I can manage to get the sharp picture in colour, that would be great!
