The above link shows the specs you're after. For guaranteed accuracy, the users manual that comes with the monitor should be consulted though.
For comparison, my SyncMaster 2243WM uses the following specs (same as the above link shows for yours):
HorizSync 30.0 - 81.0
VertRefresh 56.0 - 75.0
And generally, an LCD such as these operate at a vertical refresh rate of pretty near 60Hz.
Mara beat me to it!
