force a refresh rate

hi

i installed opensuse 11.2 on a 4200+
this computer have a nvidia video card and a crt monitor

with 11.1 i was able to use 1600x1200 at 100Hz
with 11.2 i’m only able to get 1600x1200 at 85Hz

how to force the 100Hz?

thanks

run:

sudo /usr/sbin/sax2

from a terminal to launch the SaX2 gui and configure your display per the ‘old’ method.

i tried sax from kde… but get the same result
