Vista - Screen refresh rate configuration

I got a LCD Monitor DVI Asus VW222U. I have installed the correct driver from
ASUS.
I got a problem with a flickering screen. I have tried to adjust the screen
refresh rate, but I am only given two option: 59Hz and 60 Hz.
I tried the monitor menu as well, but no sucess.
The monitor guide advises to adjust the clock rate under the Focus menu, but
there is no such option in the menu.
It follows my setup:
OS: Vista 64bits
Monitor: ASUS VW222U
Screen Resolution: 1680 X 1605
Screen Refresh Rate: 60Hz
Graphic Card: Sapphire X1550


Any help is welcome,

Hi Andrew,

First things first. The native resolution of your monitor is 1680 X 1050, so
if you are actually trying to drive it with the resolution you state in your
post I am surprised that it actually works at all. Secondly, the vertical
refresh rate for this monitor ranges from 56Hz to 75Hz. Check all
connections, in particular the video lead. Also check that the graphics card
is seated in its socket correctly and that all supplementary power
connections are secure (if any). Make sure that your graphics card is not
overclocked but running at factory default settings. If your graphics card
has 2 monitor ports, try using the other one.

Hi Andrew,

You could try using the analogue connection to see if that solves your
problem. Another option would be to download the latest driver for your
graphics card. These drivers are being developed all the time, and a newer
driver may solve your problem.
