Cast smartphone via CB-C71

Hi,I would like to cast my smartphone via the hub to the television via HDMI. When connecting both to the hub, the screen on the television remains black. The hub is on (green light). Is there any special action to perform to do this? Thanks and regards

Have you tried using the hub while its plugged into a power adapter?

Hi, thanks for answering . Yes I have tried to connect the hub to the power. So at the end the hub is connected to the power, smartphone and TV.

I only ask because my CB-C78 will output via HDMI but without power connected, the computer complains that it is drawing too much power. I have not yet tried to use the CB-C71, nor have I tried casting to a TV, only an external monitor. The setup should be fairly simple (I would think). I’ve got nothing else for you, sorry.
