In grub 2.00 I believe that what is used is the highest resolution
supported by VBE (or GOP,UGA, or whatever interface is available) that
is *also* supported by your monitor, as reported in the monitor's EDID
information.

Does your monitor support this resolution?

Well clearly that is what should already happen when gfxmode=auto, so
we need to figure out why that apparently isn't happening for you,
then go from there.
What version of grub are you using?
Could you post the full output of "videoinfo" from the grub shell,
either via a picture from a camera, serial log, or (if you're really
ambitious) typing it out manually?
