F14 New Installation: Unknown Monitor

[Burkhard Plache]

Hello Fellow Users,

after installing F14, the monitor resolution defaults to 960x600,
whereas my BenQ FP 757 has 1280 x 1024. There must be some
interface (or driver?) problem, since Preferences->Monitor does not
allow me to change to the desired resolution. I did not find any hints
on how to proceed in the docs.fedoraproject.org F14 installation guide.

Any help to a linux learning user would be appreciated.
