Well, I should have said it is part of the spec.  It is true that not
all VGA monitors support it.

Of course, I'm not sure the term "VGA monitor" even makes sense any
more.

Understood... but the monitor has seperate horzontal and vertical sync,
and I would think it would support them.  Else why have them?

Or can those signals work in tandem with sync-on-green?

Not a problem.  Arguments are effective as long as "winning" isn't your
goal.

This is a Sony branded Sony Multiscan, model 400PS.

I assume it's not a GDM model.

Of course, they use the same chassis and guts in all kinds of different
models so its hard to really know.

I don't think it would make a difference.

I wish the manual would say if it requires sync-on-green, and exactly
what kinds of input signals.
