Hello everyone,
I have a Sony Bravia KDL-42W828b, which is miracast certified. On the other hand, I have a Vaio fit 15 laptop equiped with an Intel Dual Band N 7260, which is miracast certified as well, and an Intel HD graphics 4000; the SO is Windows 8.1. I have all the recent drivers installed, I used the widi application to install all the drivers involved with the issue... I understand that everything is correct.
Well, when I try to duplicate screen I add the TV (no pin code is shown during the process in the TV), the TV prepares the conection and conection seems to success (even the transitions of frames show a small delay on the lapto's screen), but the TV is completely black. As much, sometimes it shows a first frozen frame.
Please, I need help. If everything involved is miracast certified (I consulted the official list of certified devices before buying), what is going wrong?
Looking forward for your assistance,
Kind regards.
PD: I tried disabling Windows firewall.
