I suggest you use a TV. I used to have my Amiga connected to a TV but the composite output of the A1200 doesn't have good quality. One day I was reading on the net about the RGB connection that DVD's have, and how it provides the best picture possible on PAL TVs. It has the 3 signals for the colour components separated, and it's better than SVideo. I thougt damn, and I thougt SVideo was the best one. I happened to have an old but BIG TV around that doesn't support SVioeo in, but it has RGB in!!! So I ordered an Amiga RGB output to Scart (RGB) to give it a try and was completely amazed by the result. Every picture defect that exists specially on old TVs that don't have digital comb filter (signals interfere with each other) disappears. I couldn't recognize the TV!
Actually even my friends get amazed, how come such an old TV has such good quality.
I'm even gonna buy a DVD player for it.
All due to the excellent RGB connection.
Ok, I'll shut up... :-x :-D
[EDIT] Don't forget to insist that you want the Scart connection to be RGB. Most Scart connections are composite, and actually most TV equipment sellers sell the Scart cables as if it was all the same thing. (it may be if it has all the pins on it)
