What first grabs your attention is the fact that the SD7000 in effect turns your Surface Pro into a miniature Surface Studio. It has an articulating hinge that lets you interact with the Surface Pro's display in an upright position or at the perfect angle to meet your viewing or writing/drawing needs. It also allows you to magnetically attach a Surface Pen so that it is always at the ready.
Beyond the Surface Studio-esque looks, the SD7000 also delivers when it comes to connectivity. It allows you to connect two 4K display panels (DisplayPort 1.2, HDMI 2.0) and includes four USB 3.0 ports, a USB-C port (something that the official Surface Dock doesn't support) and Ethernet. As for the dual monitor support, you can run a single monitor at 3840 x 2160 @ 60Hz or two monitors at 3840 x 2160 @ 30Hz.
The SD7000 Dual 4K Surface Pro Docking Station supports both the Surface Pro and the previous generation Surface Pro 4. The added functionality and ports do come with a steep price, however. It will set you back $299, which of course is on top of the $799+ price tag of a Surface Pro. For comparison, the official Surface Dock is priced at $299, but doesn't include the Surface Studio tricks. Kensington’s solution is also available with an optional Lock Module for securing the dock to a deck for an additional $29.99.
