Microsoft Surface Dock Review
Streamline your Surface device with the Microsoft Surface Dock. Enjoy a plethora of ports and transform your setup into a desktop-like haven with ease and flair.
The Microsoft Surface Dock (PD9-00003) connects to your Surface through the magnetic Surface Connect cable. Not USB-C. Not Thunderbolt. The proprietary Surface Connect port. This dock works exclusively with Surface devices that have the Surface Connect port: Surface Go, Surface Laptop (1st gen), Surface Laptop 2, Surface Pro 3, Surface Pro 4, Surface Pro 6, Surface Book, and Surface Book 2. If your Surface has USB-C as its primary connection (Surface Pro 7 and newer, Surface Laptop 3 and newer), this is not your dock.
That compatibility list is the first and most important thing about this product. It serves a specific generation of Surface devices. If your device is on the list, this dock transforms it into a desktop workstation with two external monitors via Mini DisplayPort, four USB 3.0 ports, Gigabit Ethernet, audio out, and power delivery through the Surface Connect cable. If your device is not on the list, stop here.

Amazon Data Error: Mini DisplayPort, Not HDMI
The Amazon structured data says “Total HDMI Ports: 2.” The actual product has zero HDMI ports. It has two Mini DisplayPort outputs. The bullets correctly state “2x Mini display ports.” If you need HDMI monitors, you need Mini DisplayPort to HDMI adapters or cables (sold separately). This is a common source of confusion for buyers who read the Amazon specs table without checking the bullets. The dock does not have HDMI. Plan your monitor cables accordingly.
Surface Connect: What It Means for Your Setup
The Surface Connect cable is a magnetic connector that snaps onto the side of compatible Surface devices. It carries video, data, and power through one connection. The magnetic attachment means the cable detaches cleanly if pulled, which protects the device from being dragged off a desk by an accidental cable tug. This is a feature USB-C docks do not provide.
The downside is that the Surface Connect port is proprietary to Microsoft. Only Surface devices have it. You cannot use this dock with any other brand of laptop. You cannot use it with newer Surface devices that have transitioned to USB-C as their primary dock connection. The dock exists for one purpose: to serve the specific Surface generation that uses Surface Connect.
If you own a Surface Pro 4 or Surface Book that you plan to use for another year or two, this dock makes that device significantly more productive by adding dual monitors, four USB ports, Ethernet, and audio. If you are planning to upgrade your Surface soon, the new device will likely use USB-C and this dock will not work with it. Factor the remaining lifespan of your current Surface into the purchase decision. For USB-C docking options that work with newer Surface devices and all other USB-C laptops, see our docking stations hub page.
Dual Monitor via Mini DisplayPort
Two Mini DisplayPort outputs drive two external monitors. Mini DisplayPort supports up to 4K resolution depending on the monitor and cable. For most users with this dock, the typical setup is two 1080p or two 1440p monitors running simultaneously alongside the Surface’s built-in display. Three screens total: the Surface plus two externals. That triple-screen configuration turns a Surface Pro 4 or Surface Book from a portable tablet into a genuine desk workstation.
Mini DisplayPort is an older standard that Apple and Microsoft adopted before the industry converged on USB-C and full-size DisplayPort. Modern monitors increasingly use HDMI, full-size DisplayPort, or USB-C inputs. If your monitors have only HDMI inputs, you need two Mini DisplayPort to HDMI adapter cables. If your monitors have full-size DisplayPort inputs, you need Mini DisplayPort to DisplayPort cables. These adapters typically cost under $10 each and are widely available, but they are not included in the box. Check your monitor inputs before purchasing so you can order the right adapters at the same time and avoid a second wait for delivery.
If you already own monitors with Mini DisplayPort inputs (common on older Dell and Apple displays), the dock connects directly without adapters. That is increasingly rare, but if you have the monitors, the connection is as clean as it gets.
Four USB 3.0 Ports
USB 3.0 transfers data at up to 5 Gbps. Four ports handle keyboard, mouse, external drives, webcams, printers, and phone charging simultaneously. USB 3.0 is the previous generation standard (USB 3.1 Gen 1 and USB 3.2 Gen 1 are the current labels for the same speed). For everyday peripherals and standard external drives, 5 Gbps is sufficient. For NVMe external SSDs that can exceed 5 Gbps, USB 3.0 is the bottleneck.
None of the USB ports specify PowerShare or always-on charging, so phone charging likely requires the dock to be powered and connected to the Surface.
Gigabit Ethernet and Audio
Gigabit Ethernet provides a wired network connection at up to 1000 Mbps. For Surface devices that rely on WiFi, the wired connection improves stability during video calls, large file transfers, and cloud sync. The audio out port connects headphones or desktop speakers. Between the Ethernet and audio ports, the dock adds two connectivity options that Surface devices do not have built in.
External Power Supply
The dock includes an external power supply that powers the dock and charges the Surface through the Surface Connect cable. No charging wattage is specified in the Amazon data. The Surface Pro 4 typically charges at 31-44W depending on the adapter. The dock likely provides sufficient power for the compatible Surface models since Microsoft designed it specifically for those devices. Under heavy load with multiple peripherals, power delivery priorities may shift, but for normal desk use the power supply handles the full setup. For how power delivery works across different connection types, see our USB-C portable monitor guide.

Who This Dock Is For
Surface Go, Surface Laptop 1/2, Surface Pro 3/4/6, or Surface Book 1/2 owners who want a desk workstation: This is the dock Microsoft built for your specific device. The magnetic Surface Connect cable provides a clean, secure connection that USB-C cannot match. Dual Mini DisplayPort drives two external monitors. Four USB 3.0 ports, Gigabit Ethernet, and audio out round out the desk setup. If your Surface is on the compatibility list and you plan to use it for at least another year, this dock makes it significantly more productive. For a different approach to Surface docking, see the Docking Station for MacBook Pro Air review for comparison with USB-C alternatives.
Surface Pro 7 or newer, Surface Laptop 3 or newer, or any non-Surface laptop: This dock does not work with your device. It uses Surface Connect, not USB-C. For USB-C docking stations that work with newer Surface devices and all other brands, see our docking stations hub page.
Final Verdict
The Microsoft Surface Dock (PD9-00003) exists for one specific audience: owners of the Surface Connect generation of Surface devices who want a desk workstation. For that audience, it is the dock Microsoft designed, tested, and certified. The magnetic connection, dual Mini DisplayPort monitors, four USB 3.0 ports, Gigabit Ethernet, audio out, and included power supply create a complete desk setup for the compatible Surface models.
For everyone else, it does not apply. The Surface Connect port is proprietary. Newer Surface devices use USB-C. Non-Surface laptops cannot connect. The Amazon listing incorrectly shows HDMI ports when the actual outputs are Mini DisplayPort. USB 3.0 is the previous generation standard. At 2.6 lbs it is heavy for its port count.
If your Surface is on the compatibility list and you need a desk dock, this is the one Microsoft built for you. If your Surface is not on the list, or if you own any other brand of laptop, USB-C docks serve your needs with broader compatibility and newer standards.
Frequently Asked Questions
Does this have HDMI ports?
No. The Amazon structured data incorrectly lists “2 HDMI ports.” The actual product has two Mini DisplayPort outputs. If your monitors use HDMI, you need Mini DisplayPort to HDMI adapter cables, which are sold separately.
Will this work with my Surface Pro 8?
No. The Surface Pro 8 uses USB-C for docking, not Surface Connect. This dock only works with Surface devices that have the Surface Connect port: Surface Go, Surface Laptop 1/2, Surface Pro 3/4/6, and Surface Book 1/2.
Is this worth buying if I plan to upgrade my Surface soon?
Consider the remaining lifespan of your current Surface. If you plan to use it for another year or more, the dock adds meaningful productivity. If you are upgrading within a few months, your new Surface will likely use USB-C and this dock will not work with it. A USB-C dock would serve both your current and future devices.
Why is it 2.6 lbs?
The dock includes an external power supply that adds weight. The Surface Connect cable and the internal circuitry for dual display output and four USB 3.0 ports contribute to the overall mass. Modern USB-C hubs are lighter because they draw power from the laptop rather than including their own power supply.
Can I use this with a Dell or HP laptop?
No. The Surface Connect port is proprietary to Microsoft Surface devices. No other brand uses it. For universal docking, USB-C hubs and Thunderbolt 4 docks work across brands.

Docking Station Intelligence
The standards are confusing by design. These three panels decode what manufacturers won’t explain clearly. Applicable to every docking station.
The USB-C Confusion Matrix
The USB-C connector is the single greatest source of buyer confusion in docking stations. The physical plug looks identical whether it carries USB 2.0 at 480 Mbps or Thunderbolt 5 at 120 Gbps — a 250x difference in capability hidden behind the same shape. Manufacturers exploit this by labeling everything "USB-C compatible" without specifying which protocol runs through it. Two docks can look identical on the outside and behave completely differently once you plug them in.
The hierarchy matters because it determines everything: how many monitors your dock can drive, how fast files transfer, whether your laptop charges while docked, and whether you need third-party drivers. Here is the real capability ladder, from slowest to fastest:
The practical takeaway: if your laptop has Thunderbolt 4, buy a Thunderbolt dock. If it only has generic USB-C, verify whether it supports DisplayPort Alt Mode before buying anything with multi-monitor claims. Our buying guide walks through verification steps for every major laptop brand.
Power Delivery: What the Watts Mean
Power Delivery (PD) determines whether your docking station can charge your laptop while you work, or whether you need a separate charger cluttering your desk. The math is simple but rarely explained: your laptop draws a specific wattage under load, and the dock must match or exceed it. If the dock delivers less than your laptop needs, the battery slowly drains even while plugged in — defeating the purpose of a docking station entirely.
Most ultrabooks need 45–65W. Standard business laptops need 65–100W. Gaming and workstation laptops can demand 100–140W or more. The dock’s advertised PD wattage is the maximum it can deliver to your laptop — but this drops if you charge other devices (phones, tablets) through the dock simultaneously. Always leave a 15–20W margin above your laptop’s requirement.
Check your laptop’s original charger wattage — that’s your baseline. Our FAQ covers how to find this for every major brand.
Native Display vs DisplayLink: The Hidden Factor
This is the decision most buyers don’t know they’re making. When a docking station outputs video to your monitors, it uses one of two fundamentally different methods: native (the dock passes your laptop’s GPU signal directly to the monitor) or DisplayLink (the dock compresses video over USB and a software driver renders it). The difference is invisible in marketing materials but profoundly affects your daily experience.
Native output through DisplayPort Alt Mode or Thunderbolt uses your laptop’s actual graphics hardware. There is zero added latency, full DRM support for streaming services, no CPU overhead, and no driver to install. DisplayLink, by contrast, adds 5–15ms of latency (noticeable in video calls and cursor movement), blocks DRM content on connected monitors (Netflix, Disney+ show black screens), consumes 3–8% of your CPU constantly, and requires a driver that Apple’s macOS security updates occasionally break.
DisplayLink exists for one reason: Apple Silicon base chips (M1, M2, M3) can only drive one external display natively. If you need two or more monitors on a base MacBook Air or 13” MacBook Pro, DisplayLink is your only option. For everyone else — Windows users, Mac Pro/Max chip users, Intel/AMD laptops — native is always the better choice.
Native (Alt Mode / Thunderbolt)
DisplayLink (USB compression)
The bottom line: if your laptop supports native multi-display output, always choose a native dock. DisplayLink is a workaround, not an upgrade. See our glossary for detailed definitions.
