How can I change the refresh rate of my monitor?

Edit the
/etc/X11/XF86Config file, then under the "Monitor" section, use your own values instead:
Section "Monitor"

Identifier "Monitor0"

VendorName "Monitor Vendor"

ModelName "Monitor Model"

HorizSync 30-107

VertRefresh 48-120

EndSection

More Information: http://www.freebsd.org/doc/en/books/handbook/x-config.html

Thank you guys for the advice :)

Comment of Dwayne (bsd_usr):
Charles,
Just a quick correction.

The conf file for xorg is located in /etc/X11 and the file is XF86Config on PC-BSD.

WARNING!!!
You should note that the handbook refers to some "target monitor".
The values for HorizSync and VertRefresh are not the default, there are no defaults.
Search manuals/Google for the frequencies that YOUR monitor can handle.

Comment of CloudNine:
This is a prime candidate for a GUI tool I feel.

Comment of Mattias:
To find the right values check your /var/log/xorg.log

Some where in this file it shows the values your monitor can handle. These values are auto-detected by your videocard.

Comment of Anglerdk:
You can also do this (also for configure your monitor/graphiccard with resolution etc) - great if your monitor isnt detected correctly and you therefore cannot change max resolution and refreshrate..

start terminal =>
write:
SU
(then write your root/superUser password)
xorgcfg -textmode

Then after a moment - a textbased GUI starts.

Then set your monitors type (the ver/hor refreshrate can normally be found on the label on the back)

remember to write new conf. file - otherwise it will not save the settings.. to test the settings press ALTGR+CTRL+BACKSPACE

Comment of Kim:
With a recent graphics card and monitor (mine aren't even all that recent), the refresh rates are autodetected by X.
So I just deleted the "HorizSync ..." and "VertRefresh ..." lines, and X then used the optimum refresh rates and switched to 1280x1024 automatically.
