I've been searching around trying to find a solution to this. With Avast firewall enabled, I am able to connect to my PC using Smart View, however it just shows up as a blank screen. When disabling my firewall it works. I'm sure there's some setting that is being blocked but cant figure out what is messing up. I don't need a link on how to create an exception, I need to figure out what setting is blocking the mirrored screen from actually showing up with Airserver.
