Start with the laptop: check its host port, support for two independent external displays and charging needs before choosing a dock with compatible monitor outputs and a data port for the scanner. A native USB-C, USB4 or Thunderbolt route suits a laptop that already supports the intended display arrangement; DisplayLink can suit some mixed or display-limited setups, but brings software requirements and model-specific limitations.
Who needs this setup?
Scanner-heavy desk workers
If you scan regularly while working across two separate screens, check that the dock leaves an accessible USB data port for the scanner and any other desk peripherals. Match the scanner connector and both monitor inputs before choosing a model.
Laptop compatibility-first buyers
If you are buying for a particular Windows, macOS or ChromeOS laptop, identify its exact model and display support. As Laptops Direct advises, two video sockets on a dock do not, by themselves, establish that the laptop can run two independent screens.
Single-cable home-office upgraders
If you want one desk connection for monitors, scanner and laptop charging, compare the dock’s host-charging output with the laptop’s requirement. Check whether the power supply is included and which USB data ports remain available.
What to check before buying
Native USB-C, USB4 or Thunderbolt video
Choose when: The exact laptop supports two external displays through the intended connection and you want to avoid a DisplayLink software setup.
Trade-off: The laptop’s own display limits still apply; the driverless StarTech.com 196UE-USBC-DOCK example is specified for Windows, not macOS or ChromeOS.
DisplayLink
Choose when: A compatible dock needs to serve an older USB-A host or a laptop whose native display route cannot provide the required two screens.
Trade-off: Check the exact dock’s operating-system support and driver requirements. StarTech.com says DisplayLink devices on macOS 10.15 or later require DisplayLink Manager.

What to check |
Who this matters to |
| Two separate displays |
Check the exact laptop’s external-display support and the dock’s simultaneous resolution and refresh-rate specification. |
I need different work on each screen, so two video sockets alone are not enough. Around 36% of consumers put independent displays first. |
| Scanner and USB access |
Match the scanner connector to a downstream USB data port and check that enough ports remain for other peripherals. |
My scanner needs a usable data connection alongside my usual desk devices; for around 29% of consumers, peripheral access is the main concern. |
| Laptop charging |
Compare the dock’s host-charging output with the laptop’s requirement and check whether a power supply is included. |
I want to leave a separate laptop charger out of the desk setup. Charging is the first priority for around 21% of consumers. |
| Different laptops |
Check supported host connections and operating systems, including any DisplayLink software requirements. |
Our desk may be used with an older USB-A laptop or a Mac with native display limits; around 14% of consumers prioritise that flexibility. |
Common buying mistakes
-
Assuming two video sockets guarantee two extended screens
The laptop and connection route still matter. Apple says the number of external displays a Mac can use depends on its model, while Laptops Direct warns against treating a dock’s socket count as proof of two independent displays.
Identify the laptop model, then check the supported display count against the dock’s stated simultaneous resolution and refresh rate.
-
Choosing a compact dual-HDMI hub without checking Mac behaviour
Anker says its Nano A210B can show different content on external monitors with Windows but mirrors them with macOS. That makes this model unsuitable when a MacBook must show different content on both external screens.
For that Mac setup, choose a route and exact model that explicitly support the required extended-display arrangement; a compatible DisplayLink dock is one option to investigate.
-
Counting every USB socket as a scanner port
A scanner needs a compatible data connection. A socket intended for charging or power input should not be counted as an available scanner connection.
Check the scanner’s connector and the dock’s downstream USB data ports, allowing for any other peripherals you plan to keep connected.
-
Assuming a dock will charge the laptop
Host charging varies by model: Plugable states that its UD-6950Z does not charge the connected computer. A dock’s display and USB connections do not establish its charging capability.
Compare the dock’s host-charging specification and supplied power equipment with the laptop’s charging requirement.
If the chosen dock does not charge the host, you will need to keep using a separate laptop charger.
Relevant brands to consider
StarTech.com
Its cited docking models illustrate both native USB-C video and hybrid DisplayLink connections.
- StarTech.com specifies two 4K 60 Hz HDMI displays, four USB-A 5 Gbps ports and two USB-C ports for the 196UE-USBC-DOCK.
- That driverless model is specified for Windows, not macOS or ChromeOS; its hybrid DK30C2DPEPUE instead requires driver installation on Windows and macOS.
Plugable
Its cited UD-6950Z is a DisplayLink dock for USB-A or USB-C hosts and desks with several USB peripherals.
- Plugable specifies two 4K 60 Hz displays and six USB-A ports for the UD-6950Z.
- Plugable says this model does not charge the host and is intended for productivity rather than gaming or protected-content playback.
Anker
The cited models range from a compact dual-HDMI USB-C hub to a larger powered desktop dock.
- Anker lists two USB-A data ports and a USB-C data port for the compact Nano A210B; its Prime A83B6 lists four USB-C and five USB-A ports.
- Anker says the A210B mirrors external displays on macOS. Check the A83B6 against the exact laptop’s display and charging limits before relying on its stated capacities.

Frequently asked questions
Can any dock with two video sockets run two separate screens?
No. Check the exact laptop’s external-display support and the dock’s simultaneous display specification at your intended resolution and refresh rate. As Laptops Direct explains, physical video outputs alone do not guarantee two independent displays.
How do I set up separate desktops in Windows?
Once both displays are connected, Microsoft Support directs Windows users to Settings > System > Display to identify and arrange them. If a screen is missing, check its connection and use the display settings to detect it.
What does a DisplayLink dock need on a Mac?
For macOS 10.15 or later, StarTech.com says DisplayLink devices require DisplayLink Manager. Check the exact dock’s Mac support, install the required software and allow the permissions needed for it to run.
Will a docking station charge my laptop?
Not necessarily: Plugable says its UD-6950Z does not charge the host computer. For any dock, compare its stated host-charging output and power-supply arrangement with your laptop’s charging requirement.
