W540 External DIsplay won't let me set Portrait with landscape on mobile display

I have a W540 with Nvidia Quadro K1200M with Windows7. The external monitor is connected to the display port on the dock. Advanced is configured for display in BIOS. When I go into Windows to set screen orientation, it only lets me select that for the mobile display - it is greyed out for the external display (HP E232). If I select Extend These Displays, then the mobile display goes into Portrait but external monitor is black. Othewise external display does not work at all. How can i make the external display work (Extend these displays) and have it set to Portrait?
