at the limits of those accepted by your Monitor. Try to set up a more
conventional timing scheme in the XF86Config. This can also happen, if
you aren't close to the Monitor's physical limits: some multisync
don't accept all possible timing combinations, but just a limited
number of setups.
BTW it is the better case when the Monitor remains blank: older Monitors
can get destroyed, when trying to feed video signals outside the limits
(they might produce too high anode voltage).
