Setting non-X Vertical Refresh rate

Heya; I've got SuSE 9.1 Personal with a flawlessly working X configuration. X is fine, but everything else runs with the wrong vertical refresh rate. I can still see everything, but I can't pan my old 15" Panasonic E15 monitor far enough over to see the entire screen, and the part that hangs off the left sorta folds underneath the rest. I've had this before, and it's solved by setting the vertical refresh rate to 75Hz. (As opposed to 60Hz, I believe.) How do I do this? I know how for X, but not... um... whatever you call everything else. Thanx, ES
