Default 3D vision, panel refresh rate and locked brightness

Hi all,

I've got a Quadro FX 4800 and Samsung Syncmaster 2233 RZ (3D vision ready) running under Linux.
I currently have the 260.19.26 driver.

My problem is this one: as soon as it receives a 120Hz signal, the Samsung panel locks the brightness and contrast to the maximum value (cannot be changed). This is not comfortable at all except for viewing in 3D with the glasses.

In early versions of the nvidia-settings, I could dynamically switch the refresh rate to 60Hz. Is it possible to have this feature back in the driver ? Better: automatically switch to 120 Hz only when stereo flipping is on, would be great...

Does anyone know a workaround for that ?

Interesting, I had the same problem with an AW2310, but it was fixed in 256 and newer drivers (the controls are not locked when its at 120hz anymore). When I first got the display, with the available drivers I wore sunglasses, this thing is so bright. I leave mine set at 120hz all the time in Xorg.conf.
