Did you find this page:

                                                  ^^
It shows all the actual specs for your monitor....

Was that a typo?  I know its just a text field.  FS = Flat Screen?
FP = Flat Panel?

Er, uh, I believe that you will be better of specifying ranges for the H
and V fields, not single numbers.  The more possible values available
there, the more modes will be available to you....

HorizSync	30 - 83
VertRefresh	50 - 76

(from the BenQ spec sheet)

Then again, maybe you only need to specify numbers that will get you
that magic 1280x1024 mode working....

I would think that if you leave out the "Screen" section, you will gain
all the modes possible based on the H & V calculations, and you can at
least select 1280x1024 from the list if it isn't the default mode....
Then again, I too have trouble pairing my xorg.confs of extraneous
information just because I've been adding modes to them for years just
so see how many I can get to work on my monitors.  That may have
something to do with my blowing so many CRTs back in the day by
overdriving them a little just to get some extra resolution on them that
they really couldn't handle.   B^)
