This is gonna sound kind of weird, how do I go about setting my monitor fresh rate to only 60hz?

the reason being that my screen shakes quite a bit when it's set to any refresh rate higher than 60hz and lower than 85hz. I think it's a problem with the power being supplied in my house/neighbourhood. Cause when I moved it else where, it was fine.

Anyways, all the information I found online so far are how to set the refresh rate to the highest possible, not never one to set it to a lower desired refreshrate.

I have RH9 installed with 2.14.20-13.9 kernel

monitor is HP D2838 M700 17-inch
Horizonal refresh rate 30.0 - 86.0 kHz
Vertical refresh rate 50.0 - 160.0 Hz

Graphic card is Nvidia Geforce 2 gts 32mb with latest nvidia driver.

current resolution is 1280x1024
current refresh rate is 80hz, but the screen is still a bit shaky ( not to
mention flickering ) at 60hz in winxp, the screen is at least stable.

thanks in advance

you should be able to either edit this in your xf86config file where you see this:

Section "Monitor"
Identifier "Monitor0"
VendorName "Monitor Vendor"
ModelName "Monitor Model"
HorizSync 30.0-96.0
VertRefresh 50.0-150.0
Option "dpms"

so you can edit it there or in the control centre - under look n feel I think (I don't use red hat 9, I use 7.3 so mine is different). Either way should work. I would normally warn you about doing this cuz if done incorrectly, you can damage your monitor, but if you have done it before, then that's up to you.

you should rerun your xf86cfg program, whichever
you want to use, and select the monitor type you wish.
if you want 1280x1024 at 60hz, then select a monitor
that says 1280x1024 at 60hz vertical refresh.

gm.. 60Hz on crt.... i'm getting a headache by
only thinking of it..

yea, 60hz feels like it vibrates my whole skull.
my last monitor would whine horribly above 75hz, and
of course 60 or 58 looks like crap. i always had to have
it set specifically to keep from feeling like i was being
attacked.

well, i don't have much choice here

it's either to go crazy from mad flickering or
go crazy from mad flickering PLUS trembling screen

so...
