HACK
To determine your optimal refresh rate, visit http://xtiming.sourceforge.net/
cgi-bin/xtiming.pl, and enter your monitor specifications in the Basic Config-

more than four years old, you should double-check whether it is noninter-
laced by Googling for specifications. There is seldom a reason to check Dou-
blescan. Once you have filled out the information, click the Calculate

a modeline to use in your
XF86Config-4 file. Copy this so that you can use it
later.

file (usually
XF86Config-4, but if you are using Xorg, the file is xorg.conf).
Before you change anything in your X configuration, though, you should

foo@bar:~$ cp /etc/X11/XF86Config-4 /etc/X11/XF86Config-4.backup
Now you need to modify the configuration file. Within the XF86Config-4 is a
section called
Monitor where you can configure general monitor settings.
Adjust the section using the information ...
