Re: Modeline problem
I'm afraid my initial euphoria was a bit premature. Having locked the frame I could see only the top half of the picture. Looking back at the waveform I realised that the vsync pulses, although now of the correct polarity, still had a 40mS interval. The modeline had not retained the interlace parameter. i.e. it has resorted to a progressive 405 line scan. So it's back to trying some more drivers in the hope that I can find one that supports interlace (I tried 307.45 that you found for me, Peter, but it does that same thing). I'm still confused as to how you got the correct output, Graham, using the same hardware, driver and OS!
