Start with what your existing laptop can drive: connect monitors directly if it has enough suitable video outputs, or consider a USB-C or Thunderbolt dock if its port and the dock support your intended displays and charging needs. A DisplayLink dock offers another route for a compatible laptop, but requires software and has workload limitations. For UK workers covered by the DSE Regulations, the Health and Safety Executive says an individual assessment should determine whether additional home-working equipment is needed.
If you move between home and another workplace, extra screen space and connections that are easy to reconnect may matter. For workers covered by UK DSE rules, the Health and Safety Executive says an individual assessment should guide any additional equipment needed at home.
A USB-C socket does not by itself establish whether you can connect a monitor or charge through a dock. Dell advises checking the exact laptop documentation and port capabilities before choosing one.
If native video outputs do not meet your needs, a DisplayLink-capable USB dock may be worth considering for routine office work. Check operating-system support, permission to install its software and the exact dock’s display limits first, as described in Synaptics DisplayLink support guidance.
Decide how the laptop will send video to each screen, then check the complete display, peripheral and charging arrangement before choosing a dock or monitor.
| Priority | What to check | Your needs |
|---|---|---|
| Direct monitor connections | Check the laptop’s native video outputs, each monitor’s input and the cables or adapters between them. Confirm the number of separate displays and their intended resolution and refresh rate; Apple says these limits depend on the Mac model and display configuration. | I want more screen space and can use separate connections if my laptop supports all the displays I plan to attach. |
| USB-C or Thunderbolt dock | Confirm video capability on the laptop port and the exact laptop–dock display configuration. Dell notes that not every USB-C port carries video; Lenovo publishes model-specific dock output configurations for named ThinkPad systems. | One desk connection would make it easier to reconnect my screens and peripherals, provided it can run the display arrangement I need. |
| Laptop charging | Compare the laptop’s charging requirement with its supported input and the dock’s stated power delivery. Check the dock’s power-adapter requirements as well as its video connection. | I would like to leave the laptop charger off the desk, but only if the chosen dock and laptop support that charging arrangement. |
| DisplayLink over USB | Check that the dock explicitly uses DisplayLink, its operating-system software and its exact multi-display limits. Dell notes USB bandwidth limitations for its universal docks; DisplayLink support documents limitations for some protected video on macOS. | My laptop lacks suitable native outputs, and I can use the required software on my device for my usual work. |
| Separate hub and adapter | Check what the USB hub connects and identify a confirmed video route separately. A connector adapter cannot give a data-only port native video capability; Dell’s port guidance distinguishes data-only and video-capable USB-C ports. | I mainly need more peripheral sockets, while an existing laptop video output can serve the monitor. |
| Home workstation suitability | Where UK DSE Regulations apply, use the individual assessment to decide whether additional equipment is needed and how the workstation should be arranged, as the Health and Safety Executive advises. | I need the screen arrangement to suit my work and workstation, not just fit the available ports. |
A dock’s HDMI sockets cannot turn a data-only laptop port into a native display output. Dell distinguishes USB-C port capabilities in its laptop guidance.
Find the exact laptop model and check its port markings and documentation for video and charging support before buying.
Several display outputs do not establish which resolutions and refresh rates work together. Apple ties external-display support to the Mac model and display modes, while Lenovo provides configurations for specific ThinkPad and dock combinations.
Check the laptop, dock and monitors as a combination, including whether the screens can operate as separate extended displays.
DisplayLink uses software-driven USB graphics. Dell notes USB bandwidth limitations for its universal docks, and DisplayLink support warns that some protected video may not play on macOS while its screens are connected.
Confirm the dock’s DisplayLink support, operating-system requirements and permission to install software on a managed laptop. Check whether the documented video limitation affects your use.
For workers covered by UK DSE Regulations, a technically compatible dock does not establish which home-working equipment is needed. The Health and Safety Executive says that should be decided through an individual assessment.
Use the assessment to identify the workstation need, then check that any chosen equipment is technically compatible.
These manufacturers and technology providers publish guidance that can help with compatibility checks; their guidance does not make every product in a brand’s range suitable for your laptop.
Dell’s laptop and dock guidance distinguishes USB-C video capability from a data-only connection and covers its universal DisplayLink docks.
Lenovo provides video-output configurations for named ThinkPad systems and docks.
Synaptics DisplayLink provides the USB graphics technology used by some docks, along with software and display-mode support guidance.
Apple’s display guidance is relevant when the existing laptop is a Mac.
These options include USB-C desk-connectivity devices and individual monitors for adding screen space to an existing laptop. Check each one against your laptop’s display connections and the workstation arrangement you need.

For a desk where two HDMI monitor connections and USB-C docking are needed. Its name specifies dual HDMI 4K output and 100W Power Delivery pass-through; check the exact laptop’s video support, intended simultaneous display modes and the power adapter required for your charging setup.
No image available
A single desk monitor for adding screen space rather than a dual-monitor dock. The named configuration has a Nano Glossy IPS display and height-adjustable stand; confirm the laptop’s USB-C video and charging capabilities before planning a one-cable connection.
No image available
For combining monitor connections with additional laptop ports. Its name lists two HDMI outputs, individually labelled 4K120Hz and 4K60Hz, plus USB, RJ45, SD/TF and USB-C PD connections; those individual labels do not establish a simultaneous dual-display mode. Check the laptop’s USB-C video capability and the combined output configuration.

A movable second screen rather than a device for connecting desk peripherals. Its name specifies a 1080P IPS display, kickstand, USB-C and HDMI; check which connection your laptop can use and how the monitor will receive power.
No image available
A portable single-screen option for a laptop with a suitable USB-C monitor connection. The named model has an IPS panel and anti-glare surface; confirm video support on the laptop port and the monitor’s connection and power requirements.
No. USB-C describes the connector, not every function behind it. Dell documents both data-only and video-capable USB-C ports, so check the exact laptop manual and port markings for video and charging support.
Confirm that your exact laptop and dock support two separate displays at your intended resolution and refresh rate. Check the video-capable host port, cables, dock output configuration and charging requirements; Lenovo’s model-specific ThinkPad dock tables illustrate why socket counts alone are not enough.
It may be an option if the particular dock supports your laptop and operating system and you can install its required software. Check its display modes and your normal workload: Dell notes USB bandwidth limitations for its universal DisplayLink docks.
Check the DisplayLink limitation before choosing that route. DisplayLink support says some protected video may not play on macOS while DisplayLink screens are connected; a native display connection and a DisplayLink connection should not be assumed to behave alike.
No specific two-monitor or dock requirement follows from the Health and Safety Executive’s home-working guidance. Where the DSE Regulations apply, it says an individual assessment should determine whether additional equipment is needed; existing equipment may be suitable or may need changing according to the worker’s circumstances.
