Note: To ensure full adapter functionality, your laptop's USB-C™ port must support USB Power Delivery and DP Alt Mode.
For a dual-monitor configuration the host laptop must support MST.
Not all USB-C™ ports support the full functionality of the USB Type-C™ standard. Ensure that your host USB-C™ port supports USB Power Delivery 2.0 or 3.0 and DP alt mode.
The adapter can connect to a host laptop's USB-C port that doesn't support USB Power Delivery 2.0 or 3.0. However, in this configuration if a power adapter is connected to the multifunction adapter, it will not pass power through to your host laptop.
The multiport adapter provides limited Chrome support (no MST support; Ethernet only when using bus power).
The multiport adapter provides limited Android support (no MST support).
A 4K-capable display is required to achieve 3840 x 2160p resolution (4K is also known as 4K x 2K).
Video output capabilities are dependent on the video card and hardware specification of your connected laptop.
