Special Notes

  • • A 4K-capable display is 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 adapter 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 high-powered USB™ devices, attach a USB-C® power adapter to the power delivery port to ensure maximum performance. Do not remove the power adapter while copying files to avoid disruption.
  • • We advise no more than one (1) bus-powered/portable external hard disk drive to be connected to the adapter at a time
  • • Supports Automatic OTA (Over-the-air) Firmware Updates for Chrome OS™
