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"
