I found the answer at last. Pressing auto adjust botton(the manual says it automatically adjust the horizontal position, vertical position, phase and clock settting) resolve my problem. Now my X can work well in both 75HZ and 60HZ.
The only trouble is when I go back to win2k, I have to let monitor adjust again because this adjust result bring flickering into win2k, and if go back to linux, another adjust is needed,.... Maybe there are difference ways between win2k and Xfree86 drawing pictures on my monitor.
