Best Thunderbolt 4 Docks of 2026

Four 4K monitors at 60Hz from one laptop is a trick almost nothing in this group can do, and this StarTech does it on Windows machines with Intel's 12th-generation chips or newer and DisplayPort 1.4 with compression. Drop to a Mac and the ceiling is two extended 4K screens on M3, M4, or M5 hardware, and with an M3 the manufacturer's notes call for the laptop closed.

Two HDMI ports on the back are what we like most about it. Most of us have HDMI cables in a drawer, and this is one of the few docks here that doesn't send you shopping for DisplayPort cables to get a second screen up. It's driverless on Intel, AMD, Snapdragon, and Apple Silicon, and 98W of power delivery keeps a 14-inch laptop at charge through a working day.

Three years of coverage is the other reason it stays on the list. Docks fail, usually at the least convenient moment, and a long warranty is what separates an annoying week from a wasted purchase. Only the SD25TB4 matches that term.

The four-screen figure is specific, though: it needs that recent Intel Windows machine, and other Windows hardware steps down to three or two screens. Check your processor before you count on four, and check how many Thunderbolt devices you plan to chain, because there's one downstream port to share.

A workstation laptop plugged into a dock that tops out at 90W doesn't charge — it drains, just more slowly than usual. Dell's WD22TB4 is the answer to that specific problem: 130W over the Thunderbolt cable, fed by a 180W adapter, which is the largest charging figure in this roundup.

The display side is aimed at the same buyer. Two DisplayPort 1.4 outputs and an HDMI 2.1 get you up to four 4K screens at 60Hz on Windows, and two further Thunderbolt 4 ports at 15W each take care of drives and a second docked machine. Five USB ports, gigabit Ethernet, and a 3.5mm jack round out the back. Nothing here needs a dongle to reach a second or third screen, which is more than several of these picks can say.

For a 16-inch machine with a discrete GPU, that combination is worth paying for: you get the screens and you stop carrying a separate charger between the office and the kitchen table. For everyone else the case is thinner, because a 14-inch ultraportable never asks for 130W and the surplus is just a bigger brick under the desk.

Two things to weigh. The Mac story is narrower than the Windows one — four 4K screens are spelled out for Windows and macOS gets a shorter sentence — so confirm your machine's external-display limit before planning two screens. Coverage runs one year, matching the UGREEN and falling short of the StarTech and the SD25TB4, which is thin for the box your entire desk hangs off.

Surface owners have the shortest decision on this page. Microsoft's dock is shaped around that laptop: one cable, 2.5 gigabit Ethernet on the back, three USB-C and three USB-A ports, a headphone jack, and a security lock slot for a desk in a shared office.

The detail we didn't expect to care about is the raised tactile marker on every port. Reaching around the back of a dock under a monitor to plug in a flash drive is normally a two-hand, flashlight job; ridges you can feel solve it without a light.

The catch is video. There is no HDMI and no DisplayPort on this one at all, so both 4K screens run over USB-C — tidy if you own USB-C monitors, an extra purchase if you don't. Dual 4K also requires a Thunderbolt 4 host, which means a plain USB-C laptop gets one external screen rather than two. It's the right dock for a Surface and the wrong one for a mixed office, where the missing video ports cost more than the neat design gives back.

Charging is quoted as a full charge in about two and a half hours rather than a wattage, so compare that with your laptop's own adapter before you commit.

Two HDMI and two DisplayPort outputs is a combination nothing else in this group offers, and it's the reason this Plugable stays on our list. Whichever cables came with your monitors, one of them fits without an adapter. Add 2.5 gigabit Ethernet, seven USB ports, and SD plus microSD readers, and the back of the box covers a whole desk.

It's a serious piece of hardware: 646 grams, a 135W adapter feeding 100W to the laptop, and enough weight that it stays where you put it when a cable gets yanked. The power supply is a full brick rather than a GaN puck, which is the price of the 100W ceiling.

Setup is driverless, and dual 4K at 60Hz is stated for M4 and M5 Macs, Windows, and USB4 laptops. On a base M3 the manufacturer asks for clamshell mode, which is worth knowing before you build a two-screen desk around a MacBook Air. Power delivery is claimed to be lab-tested to UL standards, which is the sort of detail we like to see on the part of a dock that sits under a monitor all day.

That leaves a specific buyer: one HDMI monitor, one DisplayPort monitor, and a wired network, all served from a single cable. If your two screens take the same connector, the UGREEN and the StarTech both do this job with fewer moving parts, and we rank them ahead of it for a matching-monitor desk.

A dock you upgrade instead of replace is the idea here: the rear module comes off, so a future connector standard can be swapped in without buying a new box. That modular design and three years of coverage are why it stayed in the roundup, and why it's easy to justify across a row of desks that all have to match.

The hardware underneath is conventional and sensible: two Thunderbolt 4 ports, two DisplayPort 1.4 outputs and an HDMI 2.0, four USB ports, and a 180W adapter. It picks up a Dell laptop and two screens immediately, which is the whole job, and the stated 8K ceiling means the video side won't date quickly.

Two things to weigh before standardizing on it. Four USB ports is the lightest loadout among our picks, so a desk with a keyboard, mouse, drive, and phone charger is already full. And the 180W adapter figure doesn't tell you how much of it reaches the laptop — check that against your machine's own charger first.

This is the least expensive dock in the group, and it buys three Thunderbolt 4 ports and a 140W GaN charger. If your monitors take USB-C, or you already own the right cables, that covers most of what a dock is for.

We like the power arrangement more than anything else here: a single GaN unit at the wall socket rather than a two-cord brick under the desk, delivering 85W to the laptop with the remainder spread across the ports. Three USB-A ports at 10Gbps are quick for external drives, and gigabit Ethernet is there when you want a wire.

Video is where it gives ground. There's no HDMI and no DisplayPort, so both 4K screens run over Thunderbolt or USB-C, and 85W is the lowest charge in this roundup — a large laptop will hold its level rather than gain on it. Check the dual-display notes for your Mac's chip, too, before you plan the desk around it.
