That's right, but mod 2 boundaries would be close enough to make hires
colour look pretty nice. I'm concerned that having multiples of 560 is
not even enough for full artifacts as it will look too sharp. Bring on
300dpi displays! :-)

Well, it gives you 3 digital pixels per hires pixel, so it's enough to
half-dot shift. I don't think it's possible to generate a dot more less
that two raster pixels wide in hires mode.

Just looking at the fact that rather impossible to generate a decent
result on a 'regular' 15" digital panel. I think in my case I'll not
try, and let the VGA output + the scan convertors built into such
displays handle it, and concentrate on an output compatible with
slightly larger panels
