do set second monitor portrait mode

I currently run 2x LG2010P monitors off an XFX 7900GTX. Normally, in XP, I have the second monitor setup in portrait mode. However, in Vista Beta 2, I have not found a way to set the monitor rotation. There does not appear to be any access to the normal nvidia settings menu, nor is rotation available, that I can see, in anything in the Control Panel. Any assistance in this matter would be greatly appreciated. Ron -- A8R-MVP Del X2 3800 XFX 7900GTX 2GB Corsair etc XP sp2/Vista Beta 2
