Microsoft Wireless Display Adapter

[bob3160]

Following your instructions but, I can NOT confirm your findings.
For me, once these changes described by you and GaryDaniels work.
As you can see from the photo I just took, my laptop is now projecting
to my TV using the Microsoft Wireless Display Adapter

Please make sure that your settings have actually taken. They certainly work for me.

Of course I appreciate everyone's effort to support me a lot and I also envy you for my settings are working for you  but unfortunately after double-checking all settings nothing has changed: Avast FW = ON means connect fails after a long time the MSWDA was showing "Connecting to <PC-name>", Avast FW = OFF means connect is successful and adapter shows the display like intended. Maybe you're using a different adapter FW version (mine is V.2.0.8381) or a different Win 10 Version (mine is 1909 Build 18363.778) or a different Avast version (mine is 20.2.2401 (Build 20.2.5130.570). Even switching FW back to ON after having conncted to the MSWDA successfully makes the connection break within 10 seconds or so.

Well, to be quite frank as I have to do a lot of beta testing in my professional life but getting payed for, I'm not much affected to do the same for something I'm paying for in private. Maybe compatibility to the current version of MSWDA should be put on the compatibility list for your next release tests and I'lll wait for that to solve my problem.

I'm on the beta version and after the latest update, the sharing again does not work.
I have checked and all the rules and settings are still as suggested but, the connection fails.
Guess for now, I have no choice but to switch back to the Windows Firewall.   
@hd.naujoks,
We are on the same version of MS and use the same version for the Wireless display adapter.

I've again reported this to Avast. Let's see if that helps.
