While you are in runlevel 3 use yum to upgrade your installed packages
to the latest versions. You will definitely get updates to Xorg. Once
the updates have completed use "system-config-display" to specify your
graphics adapter and monitor. Perhaps your monitor problem got fixed.
If not choose generic monitor and see if that is workable/acceptable
to you.
