Yeah, okay, force me to clarify.  Grumble.

There are cases where we can't tell what monitor the user has.  They're
almost completely described by "either the card can't do DDC, or the
cable is broken".  The former is a vanishingly small class of hardware,
voodoo1 basically.  The latter happens depressingly often particularly
with projector setups.

In either case, asking for the windows CD won't tell you what you want
to know.  It will tell you sync ranges, when what you _want_ to know is
desired resolution and display type (as in, CRT, LCD, beamer, whatever).
Afterwards you can validate that against the sync ranges from the INF
file if you want, but really, either it'll work or it won't, and asking
for the CD won't make it work better.

It's a red herring, is my point.  It's a non-feature.  It's like going
to buy a Ferrari and the salesman keeps talking about how great the
cupholders are.  They might be great, truly exemplary, but they're not
really what you're interested in.
