Virtually all monitors produced in the last 5 years have integrated
protection in the chipset somewhere... if you try to run it outside it's
frequency range it will usually drop into DPMS power management OFF state
(usually the front panel LED will flash/change colour)

Errr, no, not really. If there's a picture on the screen then generally the
monitor is happy & healthy. In the back of the monitors handbook somewhere
there might be a list of supported resolutions/horizontal/vertical
frequencies.

Sorry to be such a sod on this one but quality control on
prototype/production monitors used to be my job.
