I’ve noticed some people posting about screen mirroring being blocked when connecting to a usb-c enabled monitor, or using AirPlay.
You can bypass this with a USB-c docking station that has an HDMI port. Since the connection is to the dock and not directly to the screen, it simply thinks you are plugging an accessory in and does not block any of the streaming options like it would with a direct connection. I have been watching Netflix shows using this method for the last month since I purchased an Anker docking station on Amazon for $20.
Hope that helps some people out.
A hub or dock?
