Choose a direct monitor connection when your laptop has a confirmed HDMI, DisplayPort, Thunderbolt or video-capable USB-C output and you only need one screen. A USB-C or Thunderbolt dock can suit a fixed desk with charging and peripherals, while a DisplayLink dock or adapter can help where native outputs are limited but needs software and may have macOS content limitations. Check the exact laptop model, display limit, port capability, charging requirement and monitor inputs before buying.
People moving between home and a workplace who need a repeatable connection for a laptop, monitor and peripherals. The Office for National Statistics reported that 28% of working adults in Great Britain hybrid worked between January and March 2025.
People who need more room for documents, browser windows, email and video calls, and may only need a direct monitor cable or a simple compatible adapter rather than a large dock. The route depends on the laptop’s confirmed video capability.
People with too few native video outputs, including some USB-A-only laptops and entry-level Macs. They need to distinguish native video output from USB graphics solutions and account for DisplayLink software and content limitations where relevant.
Start with the laptop rather than the dock or monitor: confirm its exact model, available ports and supported display arrangement, then match the connection route to the desk you want to build.
| Priority | What to check | Your needs |
|---|---|---|
| External display capacity | Check the exact laptop model’s supported external-display count. Assess the intended resolution and refresh rate as one setup, and confirm that extended displays are available rather than duplicate-only output. | I need separate spaces for work documents, calls and browser windows, not simply the same picture copied to another screen. |
| Video output and cables | Identify whether the laptop port supports video output. Match HDMI, DisplayPort or USB-C connections at both ends, and use a cable rated for the required function. | I want a monitor connection that works with the ports already on my laptop, without relying on the shape of a USB-C connector alone. |
| Dock connection and charging | Confirm the required host protocol, such as USB-C DisplayPort Alt Mode, Thunderbolt or DisplayLink. Compare the dock’s available host charging with the laptop’s supplied charger and count the peripherals you will connect. | I return to the same desk and want a monitor, keyboard, mouse, network connection and power with fewer reconnections. |
| macOS display behaviour | Check the exact Mac model’s display limit and the hub’s macOS display-mode notes. A DisplayLink route needs its software and Screen Recording permission on macOS. | I need two genuinely separate external desktops on a Mac, and I may need protected video playback to keep working normally. |
| Desk fit and monitor position | Measure the desk, monitor stand or arm position and confirm mounting compatibility. Check the monitor’s footprint, VESA pattern where relevant, and safe cable routing. | I want the larger screen positioned comfortably without making the desk unstable or cramped. |
USB-C ports and cables can support different functions. Microsoft Support notes that a USB-C adapter needs a PC port configured for video output, so a matching connector alone does not confirm that a monitor will work.
Look up the exact laptop model first. Confirm the port type, video-output capability, supported display count and target resolution and refresh rate before selecting a dock, adapter or cable.
An incompatible adapter, hub or dock can mean a delayed setup and an unnecessary return.
External-display behaviour depends on both the Mac model and the hub. Apple says simultaneous display capacity varies by model, resolution and refresh rate; Anker specifies that its A210B hub mirrors external monitors on macOS.
Check the Mac’s documented display limit and the selected hub’s macOS notes. If two separate external desktops are essential, choose a native or DisplayLink route that explicitly supports that arrangement.
A hub may show the same image on both external monitors instead of providing two independent workspaces.
DisplayLink can add display flexibility through compatible USB connections, but it relies on software. On macOS, DisplayLink requires Screen Recording permission, and protected video may show a black picture while audio continues.
Use DisplayLink when it solves a confirmed display-output limitation. Install the required software, test the work applications you rely on and retain a direct monitor connection if protected-video playback matters.
A dock’s charging output can vary between laptop systems, while a comfortable dual-screen desk also depends on the monitor stand, arm, desk and cable layout.
Compare the dock’s host-power rating with your laptop’s charger requirement, count connected peripherals and measure the proposed monitor position before purchase.
You may need to keep the original charger, add cables or change an unsuitable monitor-support arrangement.
A USB-C dock route for users whose laptop supports USB-C Alt Mode, DisplayLink or Thunderbolt and who want a multi-port fixed-desk connection.
A DisplayLink-based dual-monitor dock route for USB-A or USB-C laptops where native video outputs are insufficient.
A dock option to compare for a permanent desk where charging power, warranty terms and compatibility across different laptop systems matter.
A compact USB-C hub route for laptops with a confirmed full-function USB-C, USB4 or Thunderbolt connection.
Joybuy options for a home or hybrid laptop workspace, covering fixed-desk docks, direct external monitors, a compact hub and monitor positioning after display compatibility has been confirmed.

For a regular desk needing two external displays, peripherals and network connectivity through one connection.
Stated features include dual HDMI 2.0 outputs, Gigabit Ethernet, USB ports, SD/MicroSD readers and 100W Power Delivery pass-through. Confirm USB-C video support, the laptop’s display limit and whether the required 100W+ external adapter is included.

For a fixed desk where one large screen can add room for documents, browser windows and calls.
This 31.5-inch 2560 × 1440 IPS monitor has HDMI and DisplayPort inputs, built-in speakers and VESA 100 × 100 mounting. Confirm a compatible laptop output, cable, desk position and mounting arrangement before choosing an arm.
No image available
For a portable second screen used between home, office and travel locations.
The 15.6-inch display is stated at 780 g and 11.8 mm, with a Full HD IPS panel and USB-C DisplayPort Alt Mode connection. HDMI is not supported, and the laptop must have a USB-C port with DisplayPort Alt Mode.
No image available
For connecting one compatible external monitor and desk peripherals through a compact hub.
Stated connections include HDMI up to 4K at 60 Hz, two USB-A 3.0 ports, USB-C data and SD/TF readers. Check the laptop’s host-port protocol and charging requirements; only one HDMI output is stated.
No image available
For positioning two existing desk monitors after the laptop-to-monitor connection route is working.
It supports two 19–27-inch monitors of up to 6 kg each, with independent height, tilt, swivel and pivot adjustment plus cable management. Verify monitor mounting compatibility and that the desk can safely support the combined load.
No. A USB-C connector alone is not enough: Microsoft Support says a USB-C adapter requires a PC port configured for video output. Check the exact laptop specification for video capability such as DisplayPort Alt Mode, USB4 or Thunderbolt before buying an adapter or dock.
Check the support page or technical specification for the exact laptop model, then assess the proposed display combination rather than each screen in isolation. Apple Support states that simultaneous-display capacity depends on the Mac model and the resolution and refresh rate of each display; the same model-specific approach is useful for Windows laptops.
Potentially, with a compatible USB graphics solution such as a DisplayLink dock and supported drivers. StarTech.com specifies its DK30A2DH for USB-A and USB-C hosts with a DisplayLink chipset and up to two external displays; confirm operating-system compatibility and retain the laptop charger if needed, as this model does not provide USB-C Power Delivery.
Some hubs use an arrangement that macOS handles as mirrored output rather than two independent extended displays. Anker states that its A210B hub can extend different content on Windows while macOS mirrors the same content across external monitors, so check both the exact hub and Mac model.
Yes. DisplayLink Support says macOS requires Screen Recording permission for DisplayLink Manager so the driver can render displays. It also warns that protected video may not play correctly while a DisplayLink screen is connected, so test any applications that are important to your work or viewing.
