How do you change the refresh rate for your monitor?
 

Red Hat 9

not sure exactly but it should be somewhere in the XF86Config or XF86Config-4 file located in /etc/X11/

if u play with those files i recommend changing your default runlevel to 3 in /etc/inittab and using startx incase u fudge sumthing up, and also make backup copies of those files.

a good way to regenerate XF86Config files also is to boot up a knoppix CD and let it generate one for u, save them to floppy, and put them in the X11 directory (i did this for my gentoo install).

In the monitor section of XF86Config-4 you can add:

VertRefresh 50-75
HorizSync 30-80

for example - check the real figures from your monitor handbook as you can destroy it using the wrong numbers.

These are just limits so your monitor doesn't get messed up. I think the real refresh rate is controled by the modeline for what ever mode your using.

you dont need to touch the modeline anymore its done automagically.

Hi everyone,
I'm using Mandrake 9.1 and I have the same problem of PDog. The limits in my XF86Config-4 are set to the right values, but I can't change refresh rate for my monitor; I actually run 1280x960@85Hz but I know I can set 1280x960@100Hz.
I tried to understand something on the modelines, but man pages say I have to know some specific rates that are not reported in the monitor manual nor on the manifacturer web site. Does someone know how I can determine that ?
My monitor is SONY CPD-G400

Thank you
