Do the latest graphics drivers not support miracast? Reading articles online, it seems as if they should, yet with my Radeon RX580 and the latest amd drivers installed, I am getting a 'miracast not supported by your device' error in windows 10. Further research (dxdiag) shows that the radeon rx580 drivers don't support miracast.
Was this removed intentionally, or an oversight? Microsoft just recently (within the last year) released the ability to stream pc to xbox using miracast, so it's not like the technology is dead and not used or useful.
