I recently purchased the MS wireless display adapter and Initially I have been getting the black screen whenenver I am connected. I talked with the MS support and they updated everything that needed updating. And eventually they said that my sony TV is not compatible (we even talked with a sony tech). So I tried on another TV(an emerson LED TV from walmart). It worked. I was able to update the firmware of the MS wireless dongle as well. SO I thought, I might just be able to make it work with my sony TV. So I tried and still didn't work. I tried my note 4 which previously didn't work and that WORKED! Since the dongle definitely works, I was thinking to myself maybe its just a firmware screw up in my surface. So i tried ununstalling some display adapters even the miracast adapters and reinstalling them. but no dice. tried restarting my dongle by pressing the button, still black screen. My Intel HD graphics family is on version 220.127.116.1131 the firmware on my dongle is version 1.3.8305 So maybe someone can chime in here and help?
