I got the new Samsung 2233RZ today. There is only one problem. When I switch the refreshrate above 60 with any resoltuion, the image becomes distorted

It seems like it is trying to make a 3D image even though I would prefer to just use it 120Hz.

I have updated the drivers and searched the internet for threads about the same problem but without success.

My graphics card is GeForce 8800 GT and I'm using the latest Nvidia drivers. My OS is WinXP SP3.

Any thoughts?

Thanks
