I don't understand why Microsoft couldn't make the power supply for the dock compatible with the travel charger? Or somehow allowed the dock to be more portable to be used in conjunction with the travel charger. Even if the travel charger was only capable of powering the dock and not recharge the battery, I'd be happy with that. Why is the cable going from the dock to the Surface so short? it's 50cm length I find is just not quite short enough. If it's intended to be a fixed dock, then why not stick with the SP3 dock design? I was under the impression that this dock would be more versatile and given hindsight, I would rather have bought a 2nd travel charger and a Targus dock or a wireless screen mirroring dongle. I'd also be able to use the Targus dock with my MacBook Pro and other devices too!

I agree with the other reviews here, DisplayPort is a fail, my new Dell screens will not work with the DisplayPort ports, if i use DisplayPort to HDMI adapters it works. But I shouldnt have to.. Ethernet works on and off aswell. I really expected no issues with my new Surface Pro and Dock considering we are up to Surface Pro 4 now and its still not right, my 2 had lots of issues aswell. Also considering the price points its pretty disappointing.

Completely overpriced for what it does, and I've have troubles with some monitors.

Compared to the old style "standing" dock that locks the surface pro in place, this style dock is unreliable at best. Workers consistently have connection issues to the network, external displays, mouse, keyboard, etc. You can unplug the dock from the surface and you have to plug the dock connector in 3-4 times to restore functionality to the peripherals in the dock. 6 times out of 10, functionality is more easily restored with a restart than unplugging the dock repeatedly.

As per everyone else paid so much and this device is definitely not on par. Only running one monitor which helps but I constantly need to reset it as the USB would stop responding or the monitor is not recognised. It`s a joke for the price.

Sorry to have to give such a negative review but although the dock looks neat, it suffers from terrible problems with running displays. An hour or so of trying many different 'procedures' finally gets my two monitors to work properly (at 30 Hz as per microsft's specs). However as soon as anything is altered (e.g. surface goes into standby, or one or both monitors are switched off and on for any reason, or the surface is shut down and restarted) everything has to be resetup again, again taking hours of 'fiddling'. Worse still, the 'procedure' needed to get it to work properly is not consistent, as though there is something marginal in the electronics that makes it behave in a non-repeatable way. Displays work fine individually when run from the internal surface display port. The dock really needs a total fix!

Purchased the Surface Dock only two weeks ago. After only ten days, the dock stopped recognising my 4K external monitor. Meanwhile, the monitor works fine, if I bypass the dock, and connect it directly to the Surface Pro 4. I'll be heading back to JB-HiFi to get this Dock replaced, but I'm really concerned about all the similar posts; referencing 'monitor not detected' when using the dock. The Surface Dock is an expensive port replicator, and I'd expect more from the Microsoft Hardware division.

For a device that costs a fortune, it is terrible. Using a recommended monitor does NOT work with DP at recommended resolutions and refresh rate (unnecessary purchase due to recommendations on the Surface support page - AUD 1300). Dual monitors do NOT work even when using ACTIVE adaptors (there goes another unnecessary AUD 100). USB NEVER works with this - have to plug in a separate hub to the Surface Book itself which defeats the purpose of the dock. In short avoid at all costs

The dock was working quite fine till I upgraded to 4k monitors. If I connect both of them I get only 30hz which is very jerky and unacceptable! If i connect just one picture is fine @60hz. This is using SP 2017 with i7 processor. I also own SP3 with i7 processor which can't do even output 4k @60hz to ONE monitor (max 30hz via dock or straight connection to SP3) .So disappointed.

Went to a more convenient Surface Book for working while traveling. However, I need a docking station at my destinations, but only want to use the charger portion when travelling (only pull out one black brick at the airport instead of two) but unfortunately, you can not use the docking station power supply without the docking station itself. So I find myself forced to carry three black bricks to accompany my Surface book, a massive design flaw in itself. And why is the docking station so heavy? I was annoyed with the docking station on my dell that had to be as wide as the computer, but it was light and had one transformer to power it or the computer. Also - performance of the docking station is a bit rubbish - Display rate when connecting via a serial port varies everytime I turn on the computer. Sometimes have to re-start the computer to have images display properly? Also, I have display port monitors - no display port to mini display port adaptors?
