Hi there,
I cannot connect my sony vaio duo 11 with windows 8.1 pro and sony im10 wireless display using charms window in windows 8.1.
My vaio connects to sony im10 but only black screen appears on the TV. I am sure that the connection ok because the sony im10 led turns to blue.
When i used intel widi software older version the vaio connects ok and i can see my desktop on the TV.
But it does give only black screen when using windows 8.1 built-in miracast.
I have run intel widi update tool and updated intel centrino andvanced-n 6235 network card and my intel hd 4000 graphics card.
I have went through lots of post and found no answer related to this problem.
I have attached the log file of the miracast session. hope that helps!
Regards,
Ahmad
