Bests & Worsts Reviews from Amazon

== Initial impression == - The Surface Dock 2 worked great out of the box on a Surface Book 2 and Book 3. Packaging is the same as the older dock. The new dock is similar in shape and size but 10mm deeper. Like the old Dock, the power supply is the same size as the Dock itself - MS should really include photos of the power supply in the detail page so customers can understand just how large it is. - The new dock uses the same 40-pin SurfLink connector as the previous Dock that passes along power, DisplayPort, and USB signaling (no PCIE here). The dimensions of the connector are exactly the same but the cable is ~80cm long (~12cm longer than the old dock). The AC/Mains IEC7 power cable 1 meter - twice as long as on the old dock which should help with cable routing and positioning the huge 199W power brick (15.35V @ 12.96 amps!) == Displays == [IMPORTANT NOTE]: 2x 4K60 monitors are only supported on Pro 7/7+, Pro X, Laptop 3/4, and Book 3. Less advanced models will only be able to do 1x 4K60 + 1x 4K30 or 2x 1440p at best. Microsoft's website notes this, but for some reason this info is not on the Amazon detail page.] [NOTE #2]: For non USB-C monitors, you need name-brand USB-C -> DP1.4 or USB-C -> HDMI 2.0b adapters/cables. Cheaper adapters and cables may not work well. Search for "active usb-c hdmi2 dp1.4 adapters dancharblog" - Based on the Synaptics VMM5220 DisplayPort 1.4 with DSC 1.2 which is the same chipset used in many competing USB-C/Thunderbolt-3 based docks. Search for "microsoft dock 2 teardown dancharblog" for more info on that. - It would have been nice for MS to include an HDMI or DisplayPort output to save the hassle of having to purchases adapters separately. == Power == - It does not provide more than ~95 watts to the Surface Book 2 15" so some battery drain may still happen when playing certain games on that particular device. BUT this is so much more than the 60W that the old dock delivered so should be fine for 99% of users. It does provide ~120 watts to the Surface Book 3 15" model. - With 79 watts reserved for power delivery to port, and various internal components, I don't think there will be any power issues - Did I mention how large the power supply is? Its the same size as the Dock itself. == Book 1, Pro 4, Pro 3 == - Although not officially supported by Microsoft, it seems to work OK with the Book 1 and Pro 4 - A Pro 3 did not work at all (battery failed to charge and there were Code 43 errors in device manager) == Ports == - USB @ 5Gb/s worked OK. Did not test Gen 2 10Gb/s yet - The USB hub is based on the Genesys DL3590 chipset - I do miss having front-facing USB-A for thumb drives . Hopefully USB-C based thumb drives will become more widespread. Still, MS should has left one USB-A on the front so you don't need an adapter. - It would have been nice to have a UHS-II/UHS-III SD card reader built-in - something that seems standard from competing USB-C/Thunderbolt-3 docks at this price point == Audio == - Based on Realtek ALC4106 - nothing to get excited about - A front-facing audio jack would have been nice == Ethernet == - Based on Realtek RTL8153 1Gig - Would have been nice to include RTL8156 2.5Gig at this price point == Firmware == - You can download the update tools by searching for: "microsoft dock 2 firmware update" == More photos, CAD model, and teardown guide == - Photos: search for "microsoft surface dock 2 unboxing dancharblog " - Teardown: search for "microsoft surface dock 2 teardown dancharblog" - CAD model search for: "microsoft surface dock 2 CAD model prusaprinters"
