Compare with mine:
(Also, should you not have a "Screen 1" and another section for "Screen 2"?)

You should be able to guess my preferred resolution!

And you could always use a dedicated ModeLine for what you think should 
work.

Another check: Are you looking in the correct .conf? Mine for xorg.conf 
is a link to XF86Config. (Note, no "-4".)

Good luck,
Martin
