it's very easy for config,
1- find your LCD or CRT specification, look for values named Horizontal Frequency and Vertical Frequency.

2- Open the file /etc/X11/xorg.conf
3- Locate the section "Monitor"
4- Write the values you found in step 2 in the "Monitor" Section like so :

HorizSync 31-81
VertRefresh 56-76

and do it,

for more information search about it, many of users and moderators that help to others don't reply any thing for these topics, because you can find the solution with search on the forum, or google and another search engines.
