Best Docking Stations for Multi-Monitor Setups
The difference between a laptop that feels like a laptop and one that feels like a desktop workstation is usually a single dock sitting under a monitor. Plug in one cable, and suddenly you’ve got two or three screens, a keyboard, a mouse, Ethernet and a charging laptop, all without touching a single port on the machine itself. We compared three Thunderbolt docks built for exactly that: the CalDigit TS4, the Dell Pro Thunderbolt 4 Dock WD25TB4, and the Belkin Thunderbolt 4 Dock Pro. All three do the core job well — the differences are in port count, power delivery and price.
Key Takeaways
- Most ports and power The CalDigit TS4 packs 18 ports and 98W of laptop charging into one dock, at £369.99 official UK pricing.
- Best value for a dual-monitor setup The Dell Pro Thunderbolt 4 Dock WD25TB4 covers the essentials at £266.52, noticeably cheaper than the other two.
- Simplest single-brand buy The Belkin Thunderbolt 4 Dock Pro is widely stocked and straightforward, at £399.99 official UK pricing — the most expensive of the three.
- Thunderbolt 4 is the spec that matters most All three support Thunderbolt 4, which guarantees dual 4K or single 8K display output and 40Gbps data — check any cheaper USB-C-only dock claims the same before buying.
- Power delivery wattage decides whether you need a laptop charger at all A dock rated for 90W+ charging can fully power most business laptops through the same cable that carries video and data.
Our Top Picks at a Glance
Best Overall: CalDigit TS4
The TS4 is the dock people recommend when someone asks for the best one without qualifiers, and the port count is the reason why — 18 ports in total, including three Thunderbolt 4 ports, five USB-A ports, dual DisplayPort, HDMI, Ethernet and a full-size SD card slot. For a desk that needs to accommodate two monitors, an external drive, a wired keyboard and mouse and a wired network connection simultaneously, it genuinely covers everything without an extra adapter in sight.
Official UK pricing is £369.99, confirmed directly on CalDigit's own UK store (currently a sale price, down from £399.99) — worth checking the live price before buying since CalDigit runs promotions on this model fairly often. Laptop charging goes up to 98W, enough for the vast majority of business laptops including higher-power workstation models that a lower-wattage dock would struggle to keep charged under load.
The trade-off for that breadth is price and desk footprint — it's a substantial unit compared to the more compact Dell option, and if you only need to drive two monitors and a couple of peripherals, you're paying for headroom you won't use. For a genuinely maxed-out desk setup, though, it's hard to find a competitor with the same combination of port count and power.
Best Value: Dell Pro Thunderbolt 4 Dock WD25TB4
Dell's current-generation Thunderbolt 4 dock is the pragmatic choice for a standard dual-monitor office setup — dual 4K output, USB-A and USB-C ports, Ethernet and audio, without the extra ports the CalDigit carries that most people never plug anything into.
Official UK pricing is £266.52, confirmed on Dell's own UK site, making it meaningfully cheaper than both alternatives here while still covering the core requirements most office workers actually have. Dell's docks are also validated specifically against Dell's own laptop range, which matters if your business already standardises on Dell hardware — driver support and firmware updates tend to be smoother within that ecosystem than with a third-party dock.
The port count is genuinely lower than the CalDigit, so if your setup includes an SD card reader, extra USB-A peripherals, or a third monitor, check the exact port list against your needs before buying — it's built for a solid, standard two-monitor desk rather than a maximalist one.
Most Available: Belkin Thunderbolt 4 Dock Pro
Belkin's dock sits between the other two on ports and features, but its real advantage is availability and brand simplicity — it's stocked widely across major UK retailers and Belkin's own site, which matters if you're equipping several desks at once and want predictable stock rather than chasing a sale-priced unit that might sell out.
Official UK pricing is £399.99, confirmed directly on Belkin's own UK site, making it the most expensive of the three despite sitting in the middle on raw specifications — dual Thunderbolt 4 ports, dual HDMI, 90W charging. You're paying a premium here for the Belkin name and consistent retail availability rather than for a longer port list than the competition.
If your priority is being able to order five identical docks for five desks without worrying about stock or a promotional price disappearing, that consistency has real value for an office rollout — it's a smaller factor if you're buying just one for yourself.

How to Choose a Docking Station
Frequently Asked Questions
Do I need Thunderbolt 4, or will USB-C work?
For reliably driving two or more external monitors plus data and charging simultaneously, Thunderbolt 4 is the safer bet — it guarantees a minimum bandwidth and feature set that plain USB-C docks don’t have to meet, even if they look similar on a spec sheet.
Can one dock really replace my laptop charger?
Yes, as long as the dock’s power delivery wattage meets or exceeds what your laptop’s own charger provides — check your laptop’s charger rating and match it against the dock’s stated PD wattage before assuming it’ll fully replace the charger.
Will a dock work with both Windows and Mac laptops?
All three docks here support both, since Thunderbolt 4 is a cross-platform standard. Port behaviour (like exact display resolutions supported) can vary slightly by OS and laptop model, so it’s worth checking the dock’s compatibility list for your specific machine.
Why is the Dell dock cheaper than the other two?
It has fewer total ports and a lower maximum charging wattage than the CalDigit, and doesn’t carry the same brand premium as Belkin. For a standard two-monitor office setup, that reduced feature set is often exactly enough.
Do docking stations need drivers installed?
Thunderbolt docks are largely plug-and-play on modern Windows and macOS, though checking for the latest firmware from the manufacturer’s site after first setup is worth doing — it occasionally resolves display flickering or charging inconsistencies.
Final Verdict
- Need maximum ports and charging power: CalDigit TS4
- Standard dual-monitor office setup on a budget: Dell Pro Thunderbolt 4 Dock WD25TB4
- Equipping multiple desks, want reliable stock: Belkin Thunderbolt 4 Dock Pro
The CalDigit TS4 is the strongest overall pick if your desk genuinely needs the port count and charging headroom it offers. The Dell Pro Thunderbolt 4 Dock WD25TB4 is the better buy for a standard dual-monitor office setup at a meaningfully lower price. The Belkin Thunderbolt 4 Dock Pro earns its place mainly through consistent retail availability, useful if you’re equipping several desks at once.
