This eSTUFF USB4 Dual dock features the latest VL830 high speed docking technology that turns your laptop into a powerhouse workstation combining PD power up to 100W and productivity in a compact size.

It has no less than 7 USB ports for workstation essentials like a mouse and keyboard including four 10 Gbps connections for external SSD’s.

You can connect up to 2 external monitors to the dock as long as your laptop support MST 2 monitors with resolutions up to 8K30Hz.

USB4 is a significant improvement to the USB architecture, allowing for the coexistence of several data and display protocols on a single high-speed link with a aggregate bandwidth of up to 40Gbps.

The VL830 chipset from Via Labs supports both USB and DisplayPort and is fully compatible with Thunderbolt 4 and USB4 systems. It is also backward compatible with previous-generation devices such as laptops, tablets, and smartphones that enable DisplayPort Alternate Mode over USB-C.

VL830 offers up to double the video bandwidth compared to DisplayPort Alternate Mode over USB Type-C and can simultaneously support a single display up to 8K 60 Hz high-dynamic-range display and several USB 3.2 Gen2 devices, depending on the host device capabilities.

When the host device supports DisplayPort Multi-Stream Transport (MST), multiple displays can be supported while still enjoying fast SuperSpeed USB data transfers.

Please note:
MacOS does not support MST technology.
MacOS only support Single Stream Transport (SST) mirror mode via USB.
