Second monitor not working

[bill.galloway]

All I need are the UNIX comands to reset the monitor MHZ rate to one which is acceptable to OSX. I have done this in the past but can no longer find the relevent help files online.

Please help

Or you could reset the PRAM to get the settings back to a default config.
