Allowing the driver to use DDC makes it work, so I suspect your "reduced
blank" hunch is right. How do I generate a modeline with "reduced blank"?

The reason we have to do this with a modeline is that we connect our
displays using VGA extenders and splitters that don't pass DDC to
connect multiple identical displays to one box.
