I read once where a person had a monitor that had a great picture at 60Hz refresh. Even tho it would work at 75Hz, the picture wasn't as good. It seems that something didn't like that 75Hz setting. That person used the 60Hz setting. Some things are picky that way. Higher isn't always better.
How long ago was that? If it was in the VGA era, maybe the analog circuits weren’t good enough and produced a bad signal.
In Europe, I think many CRTs were 50Hz. Basically, you need at least 24Hz to fool the eye that it's a moving picture. And if I'm correct (I never really dug into that), it's clearly something to do with the frequency of the AC supplying the monitor.
I know that has a whole series of weird effects that are "oh THAT'S why" when it's pointed out.
