During the kickstart installation of the CentOS 4.3 systems I recently built, anaconda probed for the video card (Intel 945) and monitor (NEC MultiSync 2070NX). The optimal setting for this monitor is 1600x1200 @ 60Hz. The X server is configured to use 1600x1200, but it is using a higher refresh rate, which causes the monitor to display an error message, and it also locks you out of the on-screen- menu. How do you translate a 60Hz refresh frequency into the appropriate horizontal sync and vertical refresh frequencies in the xorg.conf file? I can't find anything to change in system-config- display. Any suggestions?
Here is some information I have used as background.

The above seems thorough, but is murky in some ways - refs to apply the previous formula when there are more than one. I also seem to recall that Brian J. Smith had posted something on this. Maybe searching the archives? I hope my memory's not wrong, searches can *eat* time. He also has a blog and it would be referenced in archives too I think.
I seem to remember that there was a post of a very easy formula posted in the LinuxFromScratch archives long ago. Googling there with
site:linuxfromscratch.org
as one of the args might find that as well.
Thanks, Alfred
