That said, based on your description of the behavior it would appear that the Lenovo Thunderbolt 3 dock has what is known as a DisplayPort multi-stream hub inside of it (also known as DisplayPort MST) to drive both of the video outputs. DisplayPort MST hubs are not supported on macOS. When a DisplayPort MST hub is connected to a macOS system, all of the connected displays will be 'mirrored' and seen as one physical display as you describe. In short, the behavior you are seeing is the result of a limitation within macOS and unfortunately there is no workaround. |
