Problems connecting Anycast with Miracast in Windows 10

Hello,

I am testing my AnyCast with both mobile and Windows 10 and while on Android cast works very well, the same does not happen with Windows 10.

I am using Miracast and the device is from EzMira and followed instructions at https://www.youtube.com/watch?v=CXLQYS29tMI

In one of the PCs, I can't connect (message couldn't connect), while on the other, I can connect but the TV shows a black screen without image or sound.

Can you help?
