What do I need to know before using this adapter?
Please confirm the USB-C port on your device supports DisplayPort Alternate Mode (DP Alt Mode). Some USB-C ports only work for charging or data transfer, no video output function.

What is DP Alt Mode?
At its most basic level, DP Alt Mode means that device manufacturers would no longer need to put dedicated display ports (whether DisplayPort, VGA, or HDMI) on their devices, and could instead fill out their devices entirely with USB port for all digital I/O.

What is Multi Stream Transport (MST)?
MST is a DisplayPort 1.2 standard. MST allows multiple displays to be connected to a single DP port or USB-C with DP Alt Mode. It does this by combining multiple video signals into a single stream (a process known as multiplexing) and sending it to a device (MST Hub) that unbundles the signal.

Does the USB-C female port on this hub support data transfer?
No, the USB-C female port is only for Power Delivery.

Does it support MacOS?
It works on MacOS, but MacOS doesn’t support MST, so only one extended mode can be supported by MacOS

My laptop support DP Alt Mode, but still no display from HDMI port?

First, make sure that the USB-C multiport adapter is connected to your laptop’s USB-C port with DP Alt Mode support (normally only one USB-C port on laptop support display output).

It is possible that the extended display is disabled on your computer. Try to click WIN + P keys (in Windows 10) and check what options of display you have.

If you do not see the second screen, go to "Settings -> System -> Display" and try to detect the second screen there.
