Hi,
> I tried upgrading the driver yesterday to the 270.41.06 version but it didn't make any difference, still only 100 Hz. Are you using Windows or Linux? We're using the 64-bit Linux driver.
We had the same problem initially with the Asus VG236 until we went
into nvidia-settings and turned off Force Full GPU Scaling for the
monitor under the GPU settings. Usually this option is unchecked for
standard 60 - 75Hz LCDs but I found this was checked for some reason,
unchecked it and then the monitor went blank momentarily and came
back. Then the refresh rate increased from 99.99Hz to 119.98Hz. The
information menu in the monitor itself also showed 120Hz. This has to
be applied for every user or you can copy ~/.nvidia-settings.rc to
other users' directories. The system is currently using the 260.19.26
linux 64 bit driver running CentOS5. Here's the xorg.conf :
# nvidia-settings: X configuration file generated by nvidia-settings
# nvidia-settings: version 260.19.26

I don't know if the modelines are actually necessary. The nvidia
driver usually recognizes metamodes such as 1920x1080_120.
