What I can do is:
- connect TV and laptop to internet wifi
I can see the TV to connect on my laptop as it appears in the following image link:
Add a Device (dialogue message)
But it displays "Couldn't connect" message
I have updated to the latest firmware on my smart tv and drivers (Wifi and network) on my windows 10 laptop.
Have check that my laptop supports miracast
Have Restarted both TV and Laptop
