Display refresh rate

I got Fedora Core1 as OS, Mitsubishi Diamond Pro 750 SB monitor, and i use KDE 3.1.4-4.
The system determined the monitor correctly during installing, but it set just 85Hz refresh rate for 1024x768 resolution although the monitor supports 100Hz for such resolution. In WinXP it was used with 100Hz refresh rate.

Please tell me how i can set the needed refresh rate manually?

Here is how monitor section looks like in XF86Config file

Section "Monitor"
Identifier "Monitor0"
VendorName "Monitor Vendor"
ModelName "DPRO750SB"
DisplaySize 330 240
HorizSync 30.0 - 96.0
VertRefresh 50.0 - 160.0
Option "dpms"
EndSection

... and Screen

Section "Screen"
      Identifier "Screen0"
      Device "Videocard0"
      Monitor "Monitor0"
      DefaultDepth 24
      SubSection "Display"
            Depth 24
            Modes "1152x864" "1024x768" "800x600" "640x480"
      EndSubSection
EndSection

Thank you!

you can change the resolution by pressing CTRL+ or CTRL-. Or change the line
Modes "1152x864" "1024x768" "800x600" "640x480"

with

Modes "1024x768" "800x600" "640x480"

restart X. Now you can use your monitor efficiently.
