I have a Raspberry Pi 2 setup with OSMC media center running. It works great. I can use either HDMI or the 7" Raspberry Pi Touch Screen Display. With one display or the other it works great!
However, I'm trying to build a setup for in the car that has multiple screens. Is there a way to configure OSMC on the Raspberry Pi 2 to mirror the display to both the HDMI output and Raspberry Pi Touch Screen Display (using the DSI connector) at the same time?
