(Note: I also changed a few driver settings, compared to the automated one, in
order to use nVidia binary drivers.)

Can you run 'ddcprobe' as root and attach the output to this bug report?

Mark) Monitors are probed by DDC to be autodetected in XFree86 and the monitor's
built in rates are used unless overridden by the XFree86 config file.  If a
monitor is not in our monitor database, then it can't be overridden as we
don't have data to override it with.

If you would like us to add your monitor and other monitors by the same
manufacturer to our monitor database, please attach the Windows .INF file
for this monitor to the bugzilla report as a file attachment using the
link below.  If you do not have the floppy disk or CDROM that came with
your monitor, and are unable to locate the INF file on your system, then
you might be able to find it on the manufacturer's website under their
"drivers" section.  All we need is the .INF file however, so if you
could extract that, and attach it, we can add it to our database.

Please attach this information as soon as possible to ensure it is included
in the next release.

Sorry for answering so late. I don't have access to the monitor myself. I
installed RH 9 for a friend living quite far away. He finally sent me these
ddcprobe results:

Please test the latest OS release, Fedora Core 1, and reopen this
bug report if the problem is still present and relevant.
