      Special Notes

      • • A 4K-capable display is required for obtaining the 3840 x 2160 resolution
      • • The dock can connect to a USB-C® port that doesn’t support Power Delivery but it will not pass power through the connected device
      • • If you are using a high-powered consumption equipment, it is recommended that you use a USB-C® power supply to the power delivery port to ensure maximum performance. Attach a USB-C® power adapter to the power delivery port to ensure maximum performance.
      • • Do not unplug the power supply during data transmission to avoid data transmission failure or data loss.
      • • We advise no more than one (1) bus-powered/portable external hard disk drive to be connected to the adapter at a time.
