Try 60-72 for your range,  if the monitor scrambles (it might be fixed freq
for vertical (rare)). then try 72-72, or 70 72 for the vert sync range..

Common vert sync values are:
56, 60,70,72,75,85,100,120 .  Some people are sensitive to lower vert refresh
rates
and the monitor looks like a strobe light to them (usually 60 hz or less). 
Running
at 70-75 hertz stops the strobe effect (for those that can see it) and reduce 
eye-strain/headaches.
