Desk / Decision guide
The one-cable desk is real, but it only works when wattage, display bandwidth and USB bandwidth are all right at once.
Specifications checked against manufacturer documentation at the time of writing. Sources are listed at the end.
Match the dock to your charger's wattage and your monitor count. Anything cheaper than that is a cable adapter with ambitions.
A dock earns its place when you plug and unplug a laptop every day and you run more than one external display. If you leave the laptop on the desk permanently with a single monitor, a USB-C to HDMI cable and your existing charger do the same job for a tenth of the money. The decision is about how many things need to wake up at once, not about port count.
The pitch is simple and it is true: one cable, and the laptop charges, the monitors light up, the webcam connects, the headset connects, and the network comes up. Carry the laptop to a meeting, come back, plug in one connector.
What breaks that promise is that three separate budgets have to balance at the same time, and a dock's marketing only ever foregrounds one of them.
The first is power. The second is display bandwidth. The third is USB bandwidth, which is the one that quietly ruins video calls, because a webcam is the most bandwidth-hungry thing on most home desks.
Before you buy anything, do a cheap test. Plug the webcam directly into the laptop and run a call, then plug it into whatever hub you already own and run another. If the second one is softer or chops during movement, the hub is the problem, not the camera.
Four routes, and the right one usually falls out of the monitor count.
| Route | Power to laptop | Data bandwidth | Displays | The compromise |
|---|---|---|---|---|
| Thunderbolt 4 dock (CalDigit TS4) | Up to 98W | 40Gb/s, with 10Gb/s USB ports | Dual 6K60 on capable hosts | Costs as much as a monitor |
| USB-C dock (Anker 575) | 85W | 10Gb/s | One 4K60, or two at 4K30 | Two monitors means 30Hz |
| DisplayLink dock (Plugable UD-6950PDZ) | 100W | USB 3 with software compression | Three 4K60, even on a one-display laptop | Needs a driver, and spends host CPU |
| Cheap USB-C hub (Anker 341) | 85W passthrough | Mixed, including USB 2.0 | One 4K30 over HDMI 1.4 | Not a desk solution |
Power first, because it is the easiest to get right. Look at the wattage printed on the charger your laptop shipped with, and buy a dock that meets or exceeds it. A 98W dock keeps a laptop topped up through a long call; a 60W dock on a laptop that wants 96W will slowly lose ground while the camera, the encoder and two displays are all running. CalDigit's own Element Hub is a good illustration of the distinction: it is four Thunderbolt 4 ports and four USB-A ports with 60W to the host, no Ethernet and no HDMI. That is a hub, and a very good one, but it is not the thing that replaces your charger.
Display bandwidth is where the spec sheets get evasive. A plain USB-C dock drives monitors over DisplayPort Alt Mode, which borrows lanes from the same connection the data uses. That is why Anker lists the 575 as a single 4K at 60Hz, two 4K at 30Hz, or three displays at 1080p. Two 4K monitors at 30Hz is a real configuration and it is genuinely unpleasant, because a 30Hz cursor looks broken to everyone watching your screen share.
Thunderbolt 4 sidesteps that by carrying much more total bandwidth. CalDigit rates the TS4 at 40Gb/s with dual 6K60 support on hosts that can drive two displays.
DisplayLink takes a third route. It compresses the display stream in software on your computer, sends it over ordinary USB, and decompresses it in the dock. Plugable's UD-6950PDZ uses it to drive three 4K60 displays over one USB-C cable, including from laptops that natively support only one external monitor. The cost is a driver install and host CPU time, continuously. On a video call that CPU is already running the video encoder and, if you use it, background blur. Our background guide covers how much of a problem that second job already is.
Find out how many external displays your laptop supports before you shop. This is the single most common disappointment, and it is not the dock's fault. CalDigit states plainly that base M1 and M2 Macs support only one external display, while Pro and Max chips and Intel Macs support two. No Thunderbolt dock changes that. A DisplayLink dock does, which is the main reason to choose one.
Then work out what your webcam needs. An uncompressed 1080p60 stream is roughly 2 Gb/s of raw data, which is about four times what a USB 2.0 connection can carry at 480Mb/s. That is why the budget hub matters here: the Anker 341's USB-C data port is explicitly USB 2.0, and its two USB-A ports are 5Gb/s. Plug a good webcam into the wrong port on a cheap hub and it falls back to a compressed mode or drops frame rate, and you will blame the camera.
Audio is less hungry and more fragile. A USB microphone or interface needs very little bandwidth but hates sharing a controller with something that saturates it. If your audio crackles only when the camera is on, move one of them to a different port, or to the laptop directly. The symptom overlaps with the ones in our echo guide, so check the simpler causes there first.
Count the cables you still need. A dock does not usually include the display cables, and a dock with DisplayPort output and a monitor with only HDMI input is a part you have to buy. Budget for one cable per display plus a Thunderbolt or USB-C host cable if the dock does not ship one.
Finally, the cheap hub trap specifically. A sub-forty-dollar hub typically gives you HDMI 1.4, which tops out at 4K30, one USB 2.0 data port, and no power supply of its own, so everything it runs is drawing from the laptop. It is an excellent thing to keep in a bag. It is a poor thing to build a permanent desk on, and the first casualty when it is overloaded is the video stream.
Skip the dock if you run one external monitor and leave the laptop plugged in all week. A USB-C to HDMI or DisplayPort cable plus your existing charger is two cables, and two cables is not a problem worth two hundred dollars.
Skip it if you are about to buy a monitor anyway. A monitor with USB-C power delivery and a built-in hub does the dock's job with one fewer box, one fewer power brick and one fewer thing to fail. Weigh that against the second monitor decision before you buy both.
Skip Thunderbolt specifically if your laptop's USB-C port does not carry it. Many do not, and a Thunderbolt dock on a USB-C only host will either run in a reduced mode or not run at all.
Skip the whole category if your complaint is desk clutter rather than plugging in. A dock adds a box and a power brick. It reduces the cables you touch, not the cables that exist.
These four cover the realistic range: the dock you buy to stop thinking about it, the one that fits a single-monitor desk, the one for a bag, and the route that replaces a dock entirely.

18-port Thunderbolt 4 dock with 98W charging, 2.5 Gigabit Ethernet and 10Gb/s USB throughout.
Thunderbolt 4 at 40Gb/s, 98W to the laptop and 2.5 Gigabit Ethernet, which means the webcam, the audio interface and two monitors stop competing for the same narrow pipe. It is the dock you buy once and stop thinking about.
13-port USB-C dock with 85W host charging, 10Gb/s data, dual HDMI 2.0, DisplayPort and Gigabit Ethernet.
85W to the host and 10Gb/s of data is enough for a laptop plus a single 4K60 monitor and a webcam. Read the display line carefully: two monitors on this dock run at 4K30, which looks fine until you move a cursor while screen sharing.
Pocket 7-in-1 USB-C hub with 85W passthrough charging, two 5Gb/s USB-A ports, HDMI and card slots.
Seven ports for the price of a cable, and it passes 85W through to the laptop, so the charging half of the one-cable promise works. Its USB-C data port is USB 2.0 at 480Mbps and its HDMI is 1.4 at 4K30, so it is a travel part, not a desk.
27 inch 4K UHD monitor with 96W USB-C power delivery and a built-in USB 3.2 hub, so one cable charges the laptop and drives the display.
A 4K monitor with 96W power delivery and a USB hub built in does the same job with one fewer box on the desk. There is no Ethernet on it, so check whether your calls need a wired connection before you take this route.
The CalDigit TS4 is our pick because it removes every bandwidth argument at once. Three Thunderbolt 4 ports at 40Gb/s, three USB-C and five USB-A ports at 10Gb/s, 2.5 Gigabit Ethernet, DisplayPort 1.4, SD and microSD, and 98W to the laptop. The webcam and the audio interface are not competing with the displays. It is expensive, and that is the honest compromise.
The Anker 575 is the sensible middle. 85W to the host, 10Gb/s data, Gigabit Ethernet, two HDMI 2.0 and a DisplayPort, plus card slots. It is the right dock for a single 4K60 monitor and a webcam. It is the wrong dock if you want two 4K monitors at a sane refresh rate, and Anker's own specification says so.
The Anker 341 is the budget pick with its limits stated out loud. Seven ports, 85W passthrough charging to the laptop, two USB-A ports at 5Gb/s. Its HDMI is 1.4 at 4K30 and its USB-C data port runs at USB 2.0 speed. Use the USB-A ports for the webcam, treat the HDMI as a meeting-room part, and it is a genuinely useful forty dollars.
The ASUS ProArt PA279CRV is the alternative worth considering before you buy any of the above. It is a 4K monitor with 96W of power delivery over USB-C and a USB 3.2 hub built in, so one cable from the laptop gets you the display, charging and a couple of ports. There is no Ethernet, which rules it out if your company requires a wired connection, and the built-in hub is small. For a one-monitor desk it is still the tidiest answer on this page.
