the monitor frequency you see in windows is "VertRefresh" from
xorg.conf. You don't have to specify a range, you can also give a
discrete value.

be careful just randomly changing these values - you can sometimes to
bad things to your monitor.
To stop this, X probes your monitor (if it supports EDID) to get the
refresh and sync values it can display, and it won't let you set the
value outside this.
I would troll through /var/log/Xorg.0.log and see if you can see
anything interesting about EDID or sync, etc.
HTH!
