Apple TV is only getting better with age, but that doesn't mean it's perfect.
I want to be able to move between screens on the laptop and have the secondary display on the TV freeze on that document so that I can read what else I need to search for. Choose Force Quit from the Apple menu or press Command+Option+Esc keys. The f4 key will turn the laptop screen back on ONLY if I was away from the computer for a short enough time that I don't have to log back in.
To get more reliability when you project your screen to your smart TV, it’s good to use HDMI adapter.
