Troubleshooting:

To check if there is a problem with all ports connected to the hub or is it that a single interface is receiving limitations.

Please check following below：
 1. Tried other USB C devices on the hub.
 2. If HDMI won't work, but other port can. Check if the HDMI to HDMI cable works in good conditions, try a different HDMI cable and output display.
 3. Try to reverse the two USB C ends of the USB C connected cable and reconnect.
 4. Mac User: Try to reset the System Management Controller (SMC) 
     Windows User: Try these solutions.
 5. Please don't swap the detachable cable that came from the hub.

  *Note:
  · The USB C port on the other side is a Power delivery Port, it only can be used to supply power.
  · The detachable USB C to C cable that came with the hub, can’t be replaced by our USB C to C 2.0 charging cable.
