Hello,
I have the last version on Nvidea Natit driver, but I can;t find a way of display's rotation.
May I do it somehow?

If you go to System Preferences -> Displays, on the bottom right should be a pop-up menu for Rotation.

if in sysstem profiler you don't see rotation: supported it can't be done

i'm in the same situation, i guess we have to wait further natit development

Nothing there. Will wait for this option in new versions of the natit.
