Finding the right Targus docking station for your Microsoft Surface depends on the configuration of the workstation and the applications to be run on it. Luckily for you, almost any Targus dock can be used with any W10 Surface.
All Surface host devices featuring USB-C Alternate Mode ports work with any Targus docking station models DOCK1XX, DOCK3XX, DOCK4XX, and DOCK5XX. Performance is consistent with the specifications of the Surface and the Targus dock. They work very well together.
The newest Surfaces, including the Surface Pro and Pro X, Surface Laptop and Book, Surface Go and Laptop Go, and Surface Duo support Power Delivery over USB Type-C compatible with any Targus docking station with Power Delivery or Power Delivery Pass-Thru features.
Productivity improvements with older Surface hosts that do not have USB-C Alt. Mode ports are best realized by connecting their USB-STD-A ports with a Targus universal docking station — DOCK1XX, DOCK3XX, and DOCK5XX. For four monitor connectivity, consider the DOCK520.
The DOCK190 will always be a great solution for almost any Surface application but may be considered overkill with the Surface Go 2 or Surface Pro X where a DOCK180 may be a more economical solution. For more about the DOCK190, read this previous Tech Talk blog entitled "The Answer Isn’t 42, It’s DOCK190!". For those who want four 4K60P monitors with a Surface Laptop 3 or Book 3, SP7 or SP7+, the Targus DOCK570 is recommended.
Those intolerant of the universal but aggressive adaptive compression algorithm of Synaptics DisplayLink may prefer an USB-C Alt. Mode solution like the DOCK430. In fact, the Intel 11th Generation CPU-based graphics in the SP7+ support three external monitors without the need to disable the internal monitor. In many ways, the Surface Pro 7+ graphics rival those of more expensive Thunderbolt host solutions.
For those that know they will be traveling with their Surface, the DOCK419 is an excellent, single-monitor solution with Power Delivery Pass-Thru and fits nicely in luggage or a Targus bag. It is also recommended for those you want to connect their TV up to their Surface.
