How to change refresh rate in xorg.conf?

[schwim]

Hi there guys, I searched the forum, and found the general answer, but I'm missing the obvious I guess.

I have a new Dell E176FP monitor, and in the manual, it states that it supports 50-60hz as a refresh rate.

I've set my KDE to the correct monitor, but it will only allow me the choice of 75hz for a refresh rate.

Here's my xorg.conf:


### Comment all HorizSync and VertSync values to use DDC:
HorizSync 31.0 - 80.0
VertRefresh 56.0 - 75.0
Option "dpms"
EndSection

Section "Device"
Identifier "Videocard0"
Driver "vesa"
VendorName "Videocard vendor"
BoardName "Intel Corporation E7221 Integrated Graphics Controller"
EndSection

Section "Screen"
Identifier "Screen0"
Device "Videocard0"
Monitor "Monitor0"
DefaultDepth 24
SubSection "Display"
Viewport 0 0
Depth 16
Modes "800x600" "640x480"
EndSubSection
SubSection "Display"
Viewport 0 0
Depth 24
Modes "1280x1024"
EndSubSection
EndSection

Section "DRI"
Group 0
Mode 0666
EndSection



I see a range of refresh to be made available in that section, but I don't know what to do to change it.

Will running an LCD monitor at an incorrect rate hurt it?

Ok, I get it... tough love, right?

K, the penguin helps those who help themselves, so:


### Comment all HorizSync and VertSync values to use DDC:
HorizSync 31.0 - 80.0
VertRefresh 56.0 - 75.0


is that an allowed range under vertrefresh? If my instruction manual states that 50-60 hz is acceptable, am I to change vertrefresh to 50.0 - 60.0 ?
