Best answer: Yes, the Kensington SD7000 Surface Pro Docking Station can support dual 4K monitors. However, it won't work unless each monitor is running at a refresh rate of 30Hz, which isn't ideal.

Why get a Kensington SD7000 Docking Station?
The Kensington SD7000 Docking Station is an excellent dock that essentially transforms your Surface Pro 4, Surface Pro 5, or Surface Pro 6 into a desktop PC. Once you place your Surface device into the dock, a huge array of different ports found on it become usable, including:
- 1x USB Type-C (data only)
- 4x USB Type-A 3.0
- Gigabit Ethernet
- DisplayPort++ v1.2
- HDMI 2.0
- 3.5mm combo audio port
In addition, the dock itself is incredibly sturdy and well-built since it's made out of a combination of hard plastic and solid metal. It's also very adjustable, and this gives you the freedom to set it up on your desk at whatever angle is the most comfortable for you. For more details, check out our full review.
Is it worth using dual 4K monitors?
Thanks to the ports on the Kensington SD7000, it's possible to connect your Surface Pro to two different 4K monitors. However, there is a caveat: it won't work unless both monitors are being run at a 30Hz refresh rate.
Depending on what you're planning on using dual monitors for, this could either be a very big problem or not an issue at all. Watching movies will be fine since nearly all modern film runs at 24Hz and uses motion blur. Your experience with online video will vary based on whether or not the author recorded in 30 frames per second (FPS). When browsing the web or your desktop, the experience will feel clunky on a 30Hz monitor, but it's still alright. The area where being limited to 30Hz hurts the most is gaming, as it forces you to play at 30 FPS which is not great for most titles.
Overall, I think it's best to stick with just one monitor if you want to go 4K since using only one allows you to run it at 60Hz, which makes everything about the experience significantly more enjoyable and easy on the eyes.
