HDMI output for 4.4.2 doesn't work in portrait mode

[rustychemist]

Hello,

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.

Thank you,

Russell

Hello Rusell,

Please take a look at the following thread and the explanation to the rotation:

Thanks, SergioS! I didn't see that the library updates worked for both versions of Android. I will apply the patch and let you know if I have any other issues.
