  • Verify the monitor input source is set correctly to HDMI.
  • Restart your host device.
• USB Devices Not Recognized:
  • Ensure the hub is securely connected to your host device.
  • Try connecting the USB device directly to your host device to confirm it's working.
  • If connecting a high-power USB device (e.g., external hard drive), ensure the hub is connected to a power adapter via its PD port.
  • Try a different USB port on the hub.
• No Power Delivery (PD) Charging:
  • Ensure your USB-C power adapter is functional and connected to the hub's PD port.
  • Verify your host device's USB-C port supports Power Delivery.
