A:Answer The Surface Laptop 4 has a USB-C port. It can be used to charge the laptop if you’ve got a spare USB-C adapter that puts out at least 65 watts, and it also supports video output using an adapter or special cable. But there’s only one USB-C port, and it doesn’t support the Thunderbolt 4 interface.
The MS docking station adds a video port and hdmi for multi monitor support.
