AFter my windows updated to windows 10 1909, my client shows the windows 10 1909 host as a black screen when the laptop lid is cloased.
I have set the laptop to do nothing when the lid is closed, and this used to function correctly before this windows update. If I open the laptop lid, TV connects and displays fine. If I am using I close the lid, TV still shows as connected but the remote no longer resonds.
There is obvously a change to Windows that prevents TV from operating when the display id is closed.
