You are probably trying too hard.  Fedora has had for several years a 
couple of fundamental problems with divining proper display settings.  
Many have beenn fixed, but many yet remain.

Here are some suggestions.

Disable Red Hat Graphical Boot (rggb).
    Edit /etc/grub.conf (/boot/grub/grub.conf) and remove all 
occurrences of rhgb

Remove /etc/X11/xorg.conf and let it be generated on the next boot.  The 
first time it is generated it can be confused by rhgb.  The firstboot 
startup script will recognize that your mionitor is not configured

Now then.  Still troubles?  (check with xdpyinfo | grep dimensions:)

Your monitor did not respond correctly to the EDID request.
Check /var/log/Xorg.0.log and look for EDID.  The three or four lines 
above the EDID line are the responses.  Are they correct?  If not, then 
you get to calculate a Modeline for your monitor.  The Modeline goes 
into /etc/X11/xorg.conf.

For example, the Dell 2405FPW responds with a frequency that is .5 too 
low to allow an automatic calculation of 1920x1200.

So I had to force it not to check:

        Option      "ModeValidation" "NoMaxPClkCheck"

Your mileage may vary, but almost all of the current X11R7 video drivers 
can read a EDID and do the right thing, if the monitor responds correctly.

Good luck!
