Hmm. It should be 50Hz, but modeline was:
ModeLine "720x576" 16.25 720 780 900 1040 576 600 615 6
25 -hsync -vsync interlace
Since then, I ended up just saying "Sod it" and leaving it to the nvidia auto
select, which chose a 1024x768 resolution (with no interlace), and it
delivers a much better picture! So I turned off interlacing, and all is still
well (actually, it's a *really* nice picture!). That's what I get for
assuming that I'm smarter than the GPU.
However, when I (eventually) need to go to HDTV, I suspect that this creature
will rear its head again.
Cheers,
Neil
