Dell WD22TB4 Dock Bundle review
Effortlessly tame tech clutter with the Dell WD22TB4 Dock. Enjoy dual/triple 4K displays, seamless upgrades, and robust power—all without lifting a finger.
The Dell WD22TB4 connects your Dell laptop to up to three 4K monitors, charges it through a 180W power adapter, and gives you 11 ports through a single Thunderbolt 4 cable. Plug in one cable at your desk. Your monitors light up, your keyboard and mouse connect, your network goes wired, and your laptop charges. Pull the cable out and walk away with just the laptop. Come back tomorrow, plug in one cable, and your entire workstation is exactly where you left it. That is what this dock does for your workday.
The WD22TB4 is Dell’s enterprise Thunderbolt 4 dock with a feature most docks do not have: a modular bay that accepts swappable upgrade modules. When connectivity standards change in three years, you swap the module instead of replacing the dock. Dell built this for professionals who keep their desk setup for years and want it to last. Compatible with macOS, Windows 10/11, and Ubuntu. 40 Gbps bandwidth. Two Thunderbolt 4 ports, two DisplayPort 1.4, one HDMI 2.0, USB-C 3.2 Gen 2, three USB-A ports (one with PowerShare), USB-C multifunction DisplayPort, and Gigabit Ethernet.

Dell WD22TB4 Thunderbolt 4 Dock Bundle - 40Gbps USB-C/USB-A, 1 Year Warranty with 180W Adapter, Anyhdd HMDI, DP, USB-C Cable & Cloth - Docking Station, Supports Dual/Triple Monitors & 4k Display
Triple 4K and What Your Desk Looks Like
Two DisplayPort 1.4 ports and one HDMI 2.0 port drive three 4K monitors simultaneously. The USB-C multifunction port adds a fourth video output if you need it. Connect your monitors to the dock, not to your laptop. Your laptop’s only physical connection is the Thunderbolt 4 cable to the dock. Everything else runs through the dock.
For a Dell Precision user running CAD software, that means a 4K design view on one screen, a 4K model tree on a second, and email plus Slack on a third. For an XPS user in finance, that means a 4K Bloomberg terminal, a 4K spreadsheet, and a 4K video call window. For a Latitude user in management, that means three screens of documents, dashboards, and communication tools. The workspace expands to match the work instead of the other way around.
11 Ports and What They Do for Your Desk
The two Thunderbolt 4 ports run at 40 Gbps each. One connects to your laptop. The other connects to high-speed peripherals or daisy-chains to another Thunderbolt device. The USB-C 3.2 Gen 2 port transfers files from external SSDs at 10 Gbps, which means a 10 GB project folder moves in about 8 seconds. Three USB-A ports handle your keyboard, mouse, and any USB-A device you still use. The USB-A port with PowerShare charges your phone even when the dock is powered off and the laptop is disconnected, so your phone charges overnight at your desk without leaving anything else turned on.
Gigabit Ethernet gives you a wired network connection for the stability that WiFi cannot guarantee during video calls and large file transfers. If you have ever had a Zoom call freeze mid-sentence or a cloud sync stall at 97%, the Ethernet port is your answer. All of this runs through one cable to the laptop. The desk stays clean. The workflow stays uninterrupted.
180W Power That Charges While You Work
The 180W adapter powers the dock and charges your laptop through the Thunderbolt 4 connection simultaneously. Dell Precision workstations draw up to 130-180W under load. The adapter handles that. XPS 15 models draw 65-130W. Latitude ultrabooks draw 45-65W. Whatever Dell laptop you own, this adapter keeps it charged while three monitors, Ethernet, and USB peripherals all run through the dock. Your laptop charger stays in your bag for travel. At the desk, the dock handles power.
The adapter accepts 120/230V AC at 50/60 Hz. If you travel internationally for work, the adapter works in any country with just a plug shape adapter. No voltage converter needed.
Modular Upgrade Bay
This is the feature that separates the WD22TB4 from consumer docks. The base unit has a swappable module bay. When Dell releases a new connectivity module (faster USB, newer display standard, updated Thunderbolt), you buy the module, pop it in, and the dock gains the new capability without replacing the entire unit. Consumer docks are sealed. When they become outdated, you throw them away and buy new. The WD22TB4 upgrades in place.
For an individual buyer, this means the dock you buy today can potentially serve you for 5+ years with module upgrades. For an IT department deploying hundreds of docks across an organization, modular upgrades cost a fraction of full replacements. Either way, the investment lasts longer than any sealed dock can. For USB-C and Thunderbolt connection details, see our USB-C portable monitor guide.
Ubuntu Support: The Linux Detail That Matters
Most docking stations exclude Linux. The Anker 778 does not support it. The Selore 16-in-1 does not mention it. The j5create JCD543P does not support it. The Dell WD22TB4 explicitly supports Ubuntu. If you run Ubuntu as your primary or secondary OS on a Dell laptop, this is one of the few Thunderbolt 4 docks that Dell confirms works with your system. For Linux users in development, data science, or system administration, this compatibility is not a nice-to-have. It is a requirement that most docks fail.
Important: This Listing Is an ANYHDD Bundle
The Amazon brand on this listing is ANYHDD, not Dell. The dock is genuine Dell WD22TB4 hardware. The cables and accessories are ANYHDD branded. The warranty is 1 year from ANYHDD.
Dell typically provides a 3-year warranty on the WD22TB4 when purchased directly or through authorized Dell resellers. This bundle’s 1-year ANYHDD warranty is shorter. If the dock develops a hardware issue after year one, ANYHDD’s warranty has expired. Whether Dell would honor their own warranty on a dock purchased through a third-party bundle depends on Dell’s policies and the dock’s serial number.
The trade-off: ANYHDD includes cables that Dell does not. The standard Dell package ships with just the dock and power adapter. The ANYHDD bundle adds a USB-C cable, HDMI cable, DisplayPort cable, and a microfiber cloth. If you would buy those cables separately anyway, the bundle saves that purchase. If warranty length matters more than included cables, buy directly from Dell.

Who This Dock Is For
Dell laptop owners who want one cable to power a full triple-4K desk workstation with future-proof modular upgrades: The WD22TB4 is Dell’s top Thunderbolt 4 dock. Triple 4K monitors, 180W charging, 40 Gbps, 11 ports, Ubuntu support, and modular upgradability. The ANYHDD bundle adds cables Dell does not include. If you own a Dell Precision, Latitude, or XPS with Thunderbolt 4, this dock turns any desk into a complete workstation. For a Dell dock at a lower power tier, see the Dell WD19S USB-C Dock review.
Buyers who need Dell’s full warranty or use non-Dell laptops: The 1-year ANYHDD warranty is shorter than Dell’s direct coverage. Non-Dell laptops are not confirmed compatible. For broader options, see our docking stations hub page.
Final Verdict
The Dell WD22TB4 does for your desk what the best docking stations should: it makes the laptop the only thing you carry. Plug in one Thunderbolt 4 cable and three 4K monitors wake up, your peripherals connect, your network goes wired, and your laptop charges at 180W. Pull the cable and you are mobile. The modular bay means the dock can grow with you as standards change. Ubuntu support means Linux users are not left out. Dell designed this for their own hardware, and it works with the confidence that brings.
This listing is an ANYHDD third-party bundle. The dock is genuine Dell. The cables are ANYHDD. The warranty is 1 year instead of Dell’s typical 3 years. The included cables save a separate purchase. For Dell laptop owners who accept those terms, this bundle delivers Dell’s best dock with everything needed to connect immediately. For buyers who need the full Dell warranty, buy direct from Dell. Either way, the WD22TB4 itself is an enterprise dock that earns its place on any professional desk.
Frequently Asked Questions
Is this sold by Dell?
No. The brand is ANYHDD. The dock hardware is genuine Dell WD22TB4. The cables and cloth are ANYHDD products. The 1-year warranty is from ANYHDD, not Dell. Dell’s direct warranty is typically 3 years.
Will it work with my non-Dell laptop?
The listing names only Dell Precision 7510. The WD22TB4 is designed for Dell Thunderbolt 4 laptops broadly. Non-Dell laptops with Thunderbolt 4 may work but are not guaranteed. Check Dell’s compatibility documentation before purchasing.
Why does this support Ubuntu when other docks do not?
Dell builds the WD22TB4 for enterprise environments where Linux is common. Dell provides firmware and driver support for Ubuntu. Most consumer dock manufacturers target Windows and macOS only.
What does the modular bay actually do?
When Dell releases a new connectivity module with updated standards, you swap the module into the dock’s bay instead of replacing the entire dock. This extends the dock’s useful life by years. Consumer docks without modular bays become obsolete when standards change.
Should I buy this bundle or buy from Dell directly?
The ANYHDD bundle includes cables Dell does not (USB-C, HDMI, DisplayPort, cloth) but has a 1-year warranty. Dell’s direct purchase includes just the dock and adapter but typically carries a 3-year warranty. If warranty matters more than included cables, buy from Dell. If you want everything in one box and accept the shorter warranty, the bundle works.

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.
