I have an app that works fine in both Landscape and Portrait mode, but it demos best in Portrait mode. I'd like to show this app on a phone with HDMI output (either from MHL, Slimport, or micro-hdmi) and screen mirroring to an external display.

Presently, I have a Samsung Galaxy Nexus. However, as has been pointed out by many, this phone forces the orientation to Landscape when an HDMI display is attached through the MHL adapter (see , , )

Does anyone have any suggestions on how I can do HDMI Output with mirroring and keep my phone in portrait mode?

I have the adapter from Monoprice () and a Samsung Nexus phone, but I can currently only get this to display in landscape mode, so I am looking for the same thing you are and the ability to display in portrait mode.

I don't think it is the adapter. I think it is a "feature" of the phone.
