My A1200 looks great om my 37" Panasonic...it just sits to the left of the screen a bit, using SCART (but no big deal)
I use Super High Res Laced...and there is no noticeable flicker!
Haven't tried mode promotion yet (DblPAL and so on)
I was playing Turrican II the other day and it looked and sounded great
:-)
