  • 1 - Quick Installation Guide (QIG)
System Requirements
  • Available USB-C® port that supports DisplayPort™ Alt Mode and USB™ Power Delivery 2.0 or 3.0
  • DisplayPort™ v1.4 with DSC is required on graphics card or video source to support 4K @ 144 Hz. If your system only supports DisplayPort™ v1.4 (without DSC), the 4K resolution will be displayed at 60 Hz.
  • Available USB™ Power Delivery over USB-C® to support charging to a mobile device.
Special Notes
  • The adapter can connect to an 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 the USB-C® power adapter to the power delivery port to ensure maximum performance. When using your USB-C® power adapter, the multi-adapter powers both the adapter (with attached peripherals) and your laptop.
  • 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.
  • The device may become warm to moderately hot while transferring bulk data or while a USB-C® power supply is plugged in.
