System->Administration->Display is nothing more than a pretty 
RedHat/Fedora graphical tool for configuring your X-Windows setup. More 
specifically, it will write/overwrite your /etc/X11/xorg.conf file with 
one it generates for you. Any manual changes you make to the xorg.conf 
file will be destroyed by the System->Administration->Display tool 
(/usr/bin/system-config-display).

It is my understanding that System->Preferences->Screen Resolution is a 
VIRTUAL screen sizing tool and is limited by whatever maximum setting 
you have in your xorg.conf (System->Administration->Display). If you set 
your resolution to 1024x768 in System->Administration->Display then the 
System->Preferences->Screen Resolution will be limited to 1024x768 and 
below. If you set your resolution to 1280x1024 in 
System->Administration->Display then the System->Preferences->Screen 
Resolution will be limited to 1280x1024 and below.

It is virtual because X-windows is not really running at that resolution 
and does not require an X-windows restart to take affect. I don't know 
any details as to how it works but it seems to be some kind of software 
scaling with GNOME. How it differs from X-windows being software and how 
it interacts with the video card I haven't a clue.
