I am trying to use Miracast with the Radion 7570m on a HP Elitebook 8470p. Unfortunaly its stated that miracast is not available on my device. Intel WIFI AC -7260 does support Miracast. On a simular setup, with intel GPU on board, it does work. Any idea on which driver to use for the Radion 7570m on Windows 10 to support miracast?
