To ensure full adapter functionality, your laptop’s USB-C port must support USB Power Delivery and DP Alt Mode.

USB-C is a type of USB connector that is capable of supporting the following:
Data transfer speeds up to 10Gbps, if you use USB 3.1.
Bi-directional power delivery up to 100W, if both the USB host connection and the device support it.
Alternate modes, which deliver different types of data at different speeds. For example, DisplayPort Alternate Mode (DP Alt Mode).
If using Thunderbolt 3 over USB-C, the connection is capable of additional features. For example, Thunderbolt 3 is capable of 40Gbps of total bandwidth.
Not all USB-C ports or devices are capable of supporting all of the features listed above, or all of the features at the maximum capabilities. If you require a specific USB-C feature, your USB host connection, cables, and device must all support the feature that you require.
