Yoga 720 USB-C-Port (Tunderbolt) not working?

2017-08-27, 17:05 PM

Hi,

 

I want to connect my Yoga 720 to an external monitor with the USB-C to HDMI-Adapter from Lenovo . When I plug the adapter into the USB-C-Port (Thunderbolt) it doesn't work, I also don't get a message that something was plugged into the port ...

Charging the Yoga 720 with the other USB-C-Port does work, the USB-3-Port does also work.

 

I attached a screenshort of the device manager.

Is the USB-C-Port (Thunderbolt) listed here?

 

What can I do to make it work?

 

Thanks!

I have this question too. I bought a USBc to HDMI adapter. The LED lights up only when its either powered by a USB cable or the HDMI cable. Its not recognized by either the 720 (doesn't detect the monitor) or the monitor (no video signal). So either the adapter is dead, or there is a driver issue. Maybe.
