Samsung 2233RZ - 120 hz on Mac?

[markushs]

Hi,
Has anyone managed to make the 2233RZ run at 120hz on a mac? I've tried everything (including DisplayConfigX and similar programs), but it doesn't run at more that 60hz (1680x1050 resolution).

And yes - I've got the dual-link DVI cable.

you must use the programm switchresx and there will be 120 hz.

you can change the sync from positv to negativ and back

Whenever I try to use the settings shown in the picture, after I reboot the custom resolution profile comes up as "Not Activated - Invalid?".

Has anyone figgured out how to get 120Hz out of a macbook?

I'm using a Macbook air with MiniDP>DLDVI adapter to samsung 2233RZ monitor.
