Start with your exact laptop’s video-capable port, operating system and supported number of external displays, then match the hub or dock to your screens, peripherals and charging needs. A USB-C hub may suit one display and a shorter port list; a powered dock can make sense for a fixed desk with several connections, while DisplayLink is an option only if its software requirements and viewing limitations work for you. Plugable’s compatibility guidance makes clear that two video sockets alone do not guarantee two independent displays.
If you need separate external workspaces, check your exact laptop’s display limit, video connection, operating system and supported resolution before choosing a dock. Plugable’s compatibility guidance explains why the operating system and video technology matter, not just the number of sockets.
If you regularly take your laptop away from a fixed desk, consider whether the dock can reconnect your peripherals and supply the charging power your laptop needs. Check the host power output and whether a separate charger is included.
If your work laptop restricts software installation, check that policy before considering a DisplayLink dock. DisplayLink Manager on macOS also requires Screen Recording permission.
For a fixed desk built around one laptop, confirm that the laptop can run the intended displays before choosing a hub or dock for charging and other connections.
| Concern | What to check when buying | Who this matters to |
|---|---|---|
| Independent displays | Check the exact laptop’s video-capable port, operating system and simultaneous display limit against the dock’s supported screen modes. Plugable says macOS does not use MST for multiple independent extended displays. | If I need separate external workspaces, I want to know the laptop can drive them at the resolution and refresh rate I plan to use. Around 36% of consumers put independent displays first. |
| Laptop charging | Compare the dock’s power delivered to the host with the laptop’s charging requirement; check whether a suitable charger is included. Anker’s 555 hub, for example, specifies up to 85 W laptop pass-through from a suitable separate charger. | If I reconnect at my desk and want the laptop powered through the same connection, I need the delivered power to suit my computer. Around 29% of consumers prioritise one-cable charging. |
| Peripheral and network connections | Count the USB data ports and other connections you need, distinguishing them from power input; check whether Ethernet is built in or needs an adapter. | If my keyboard, storage and wired network all stay at the desk, I want enough usable connections without buying ports I will not use. Around 21% of consumers put peripherals and Ethernet first. |
| Operating-system and software fit | Check the laptop’s operating system and whether you can install the required software and grant permissions. DisplayLink Manager requires Screen Recording permission on macOS. | If my work laptop is managed, I need a display route that its software rules allow. Around 14% of consumers prioritise software-compatible displays. |
The laptop’s graphics capability and operating system affect whether the dock can extend to the display arrangement you want.
Write down your laptop model, operating system and intended screen modes, then check the laptop and dock documentation for simultaneous display support.
A USB-C-shaped port may not support the video mode you need, and a hub’s power input is not necessarily the amount delivered to the laptop. The Anker 555’s charger is separate.
Check the host port’s documented functions, the dock’s output to the laptop and what is included. A suitable separate charger may be needed.
A separate charger may also mean another item to connect at the desk.
DisplayLink Manager needs Screen Recording permission on macOS, and DisplayLink warns that some protected video may not play while its screens are connected.
Check software installation rules and permissions before buying. If protected playback matters to you, see whether a compatible native-display connection meets your needs.
The Anker 555 USB-C Hub is an example of a compact hub for a desk setup with one HDMI display and other connections.
The Dell Pro Thunderbolt 4 Smart Dock SD25TB4 is a powered desk-dock option for a compatible Thunderbolt host and connected devices.
The DOCK116GLZ is a DisplayLink-based option with specified dual-display modes, provided its software requirements suit the laptop.
The TS4 illustrates a port-rich Thunderbolt 4 workstation dock for a compatible host and desk setup.
Plugable’s compatibility guidance is useful when comparing native MST display connections with software-based display options.
These options cover USB-C hubs and docking stations for connecting displays and desk peripherals, with charging or Ethernet features where stated in the product name.

For a desk setup that needs two displays and several peripheral connections.
The product name specifies dual HDMI 4K and 100W Power Delivery pass-through. The stated setup requires an external 100W+ adapter connected to the dock.

For a laptop desk that needs an external display and several USB connections in an adapter format.
The product name lists HDMI, two USB-A 3.2 connections, two USB-C 3.2 connections and PD power.
No image available
For a desk setup needing one external display, USB-A peripherals and pass-through power.
The product name specifies 4K HDMI, 100W PD and three USB-A data ports.
Not necessarily. Check the laptop’s external-display limit, video-capable port, operating system and the dock’s simultaneous-screen modes. Plugable says macOS does not support MST for multiple independent extended displays; Apple’s native display support also depends on the exact Mac model.
No; check the exact dock’s host-power specification and your laptop’s charging method. DisplayLink says USB Standard A–B docks are not designed to charge a computer, and USB-C charging capability needs to be confirmed for the specific model and setup.
Check that the software is compatible and that you can install it and grant the required permission. DisplayLink says macOS users must grant DisplayLink Manager Screen Recording permission; its support guidance also warns that some protected video may not play while DisplayLink screens are connected.
The applicable guidance differs by destination. UK government guidance addresses equipment supplied in Great Britain separately from equipment supplied in Northern Ireland under the Windsor Framework. For a mains-powered dock or included power supply, check the actual product and seller documentation for the destination rather than assuming one marking rule applies to every USB-powered hub.
Keep the seller’s details and check the applicable rights for your purchase. GOV.UK guidance says online buyers generally have 14 days after receiving an item to notify the seller of cancellation and a further 14 days to return it; separate remedies apply to faulty goods. A manufacturer’s warranty is not the whole of your rights.
