Special Notes

  • • A 4K-capable display and cable are required for obtaining the 3840 x 2160 resolution
  • • If connected to a USB™ 2.0 host port, or if using a USB™ 2.0 host cable, performance may be limited
  • • 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 USB™ device, attach a USB-C® power adapter to the power delivery port for optimal performance
  • • To ensure files copy completely, do not remove the USB-C® power adapter while copying files. For maximum performance, use a computer and USB-C® power adapter equipped with PD 3.0
  • • We advise no more than one (1) bus-powered/portable external hard disk drive to be connected to the USB™ hub at a time
