I think the two options are System -> Preferences -> Screen Resolution
 and System -> Administration -> Display.  The ViewSonic VG2030WM is  
 not included in the Display -> Hardware -> Monitor Type so I've been
  using the generic "LCD Panel 1680X1050".  Is there some other way I
 can tell FC6 and X exactly what monitor I have or at least get a
 higher resolution?

Doing a search for the monitor in question 

http://www.viewsonic.com/products/desktopdisplays/lcddisplays/graphicseries/vg2030wm/

Frequency
		
		
		
			
			
			
			
			
			Fh: 24~92kHz, Fv: 50~85Hz
This goes in 

HorizSync 24.0 - 92.0
VertRefresh 50.0 - 85.0 

as follows in the /etc/X11/xorg.conf.  Edit this file as root user su or su -.  Both should do the job.  Logout and/or reboot to see if it works and report back if there are problems.  

In your /etc/X11/xorg.conf

Edit "Monitor" Section 

Section "Monitor"
        Identifier "ViewSonic"   <----  Here put ViewSonic 
        VendorName "ViewSonic"  <----- put ViewSonic 
        ModelName "VG2030VM"  <----- put VG2030VM 
        HorizSync 24.0 - 92.0  <----  Got this from product guide 
        VertRefresh 50.0 - 85.0  <---- see above 
        Option "DPMS"
EndSection

and 
Section Screen 
put ViewSonic in Monitor Section and in the Modes from SubSection Display 
add 1680 X 1050 in where ----> below in your own /etc/X11/xorg.conf 

Section "Screen"
        Identifier "Screen0"
        Device     "Card0"
        Monitor    "Insignia"   <---- put ViewSonic here or what you put as Identifier in Section "Monitor"

Hope this fixes this issue.  I had a similar problem with an Insignia monitor that I fixed by myself because it did not want to display at 1280x1024 so I fixed the issue by adding the Modes Line with the resolutions there.  

       Modes "1280x1024" "1152x864" "1024x768" "832x624" "800x600" "720x400" "640x480"
