Same issue with BQ Aquaris M10 FHD with OTA 12 and this miracast dongle: http://www.emtec-international.com/nl-eu/mirror-dongle. Installed latest firmware on dongle (v8.0). It now connects, but also with black screen.
Also made the connection with an android device first as described here: https://wiki.ubuntu.com/Touch/DisplayCasting
"NOTE: To connect with the Microsoft WiFi Display dongle you have to connect it with an Android device currently first before Ubuntu is being able to stream properly to it. Otherwise you will just get a black screen."
There is no clear comment on why this would make a difference. Should the connection with the Android tablet be disconnected first or is it supposed to be 'hijacked'??
