Question [Q] HDMI/MHL possible in portrait mode?

Hello,

I need to use an MHL-Connector to present some business apps. The MHL works perfectly in landscape mode, but I don't find a solution for portrait mode. Ultimate Rotation ect. doesn't do what I need.
My Galaxy Note (N7000) works perfectly on both modes.

Is there a mod or some thing else to use the Galaxy Nexus in Portrait and Landscape mode on MHL?
