I am working on Android 4.4.2 and we are trying to use the HDMI output in portrait mode. We are using two displays: one is a touch display and the other is the HDMI output,.I am unable to get the HDMI display to work in portrait. If I flip the rotation, the screen works fine. Once I flip it back, I am left with a "snapshot" image of the screen and anything I do on the touch screen isn't replicated on the HDMI output screen. From what I've read, this seems to be a driver issue. The problem is solved in 4.4.3 but our development team is currently unable to upgrade to that. Does anyone have a patch for this? ANy help is greatly appreciated.
