Ok this should be easy for some of you Linux gurus but not for me apparently, I have the newest Mandrake installed and I am trying to set my monitor refresh rates, my problem is that my Samsung Syncmaster 753FD isn't an available option under the change monitor option and all the generic values have a refresh rate too high or too low for my monitor. My question is how can I set the refresh rates manually? This was the same problem with the newest Redhat version too, I just installed this Mandrake over Redhat to try it.
