frequency out of range although set correctly

Every now & then I get the dreaded frequency out of range box up, although it's set at the correct frequency in system preferences. I have a mac mini 4.1 intel core duo 2.4ghz. although my monitor is a Fujitsu siemens 21" screen. didn't have any trouble till updated to last 2 O/S's. Is there a fix?
