I've got it connected with the cable that came with the monitor, which
then says DVI-D.  The monitor won't let me change any picture settings, and
all the pixels are spot on. (A good test is a wide xterm window with a line
of 'm' chars in it.  When the clocks are out (as they always are for analogue)
the vertical lines (every other pixel) vary in width.)

The analogue output (on the other connector) isn't as good as on my old
AIW-128.

The default for the driver is to output to the VGA be default.  If the DVI
is connected the VGA contains a 'TV-out' resolution (640x480@50Hz) panning
image of the main screen.  I've found out how to get both output to
display the same image - at different refresh rates.
