What is Thunderbolt 4?
Thunderbolt 4 technology uses the USB-C connector and offers bandwidth up to 40Gbps. that is capable to support for the following:
- USB 3.1 Gen 1 support up to 5 Gbps data transfer rate and USB 3.1 Gen 2 support up to 1 OGbps data transfer rate
- USB Power Delivery up to 1 DOW, if both the host and the device support it
- DP Alternate modes, the signal is based on the DisplayPort version to deliver different speeds.
- PCI Express 3.0
Thunderbolt 4 products must be used with Thunderbolt 4 cables. Ensure your
Thunderbolt 4 cable is 40G with 1 DOW version.
Not all USB-C ports are Thunderbolt 4. For more information, please refer to
the information provided by the manufacturers.
DP alt mode (DisplayPort alternative mode)
This docking station supports DP alt mode, which means a DisplayPort video
signal can be transferred over a Thunderbolt 4 cable.
Because the docking station supports DP alt mode, so the Thunderbolt 4 port
can output the video directly via DP alt mode without other driver installs.
USB Power Delivery
This docking station supports USB Power Delivery, which means it delivers up to 100 watts of power to your connected host laptop (your laptop’s TBT3 port must support power delivery). USB Power Delivery is a specification that allows power to be sent over a USB-C or Thunderbolt 4 cable that supports the specification. Ensure your Thunderbolt 4 cable can support PD 1 00W transfer or use the included Thunderbolt 4 cable.

Displaylink output still can work, so total three video output max.
