Check to see if both the HDMI end and the USB end of the adapter are connected correctly.

  • Make sure the HDMI end of the adapter is connected to the HDMI on your second display. Use the included HDMI extension cable if needed.

  • Make sure the USB end of the adapter is plugged into a USB power source. If the second display doesn't have a USB charging port, use the charging port on a device power supply or another USB charger.

  • For the most reliable connection, use a USB charging port that's directly connected to a wall outlet. Use a USB extension cord if you need more length for your USB connection.

  • Make sure the electrical outlet you're using is working properly. Test it by connecting something else.
