Problems changing resolution to 1920x1080 hz 60 on a radeon HD 5700

[zniff]

benq E220HD LCD
graphic card ati radeon HD 5700

and for some reason i have a strange problem setting the resolution from 1920x1080 hz 30
to 1920x1080 hz 60.
and i tried doing so several times, first atempt made my monitor go GREENSCREEN after a restart i tried doing it again bot nothing happens after i press OK it only returns to 30 hz

and the game i tried doing this resolutionchange on is named
Sword of the stars: Argos naval yard

i was able to do this change on games liek
supreme commander 2 and cs source
and i asume that this problem might affect these games too

are u sure ur monitor supports 60hz??

The BenQ E2200HD I'm pretty sure support 60 Hz. Try installing the latest drivers, Catalyst 10.6 and see if that fixes the problem.

just checked version and it is 10.6

Maybe its just that game?

 

[zniff]

maybe, but it does not make sense. when i have the option, only to be denied.

my pc also forbids the resolution as high as 1920 x 1080. it only allows to1280 x 1024. why is that so?

i also use radeon 5700 by the way.
