W10 is kinda messed up with Miracast not like w8.1 , I tried the process it found my blackberry phone and connected to the blackberry . but I had to first add a display in settings.. the blackberry was the display it found,, hmm. it also found my Printer as a display, my printer has an 4 inch LCD and Wifi .. crazy
explain all u have tried so far , so we can figure it out. I have my G751 display on my Blackberry , printer LCD and in on my PS3/TV
