Start with what your workstation needs and what your exact laptop model can connect to. A compatible monitor connected directly may be enough for one extra screen; consider a dock when you also need to connect several desk devices, and check the laptop’s display and charging support before choosing one. In the UK, the Health and Safety Executive says workers cannot be charged for equipment their employer provides when a display screen equipment (DSE) assessment indicates that action is needed.
If you use display screen equipment daily for continuous periods of an hour or more, your home workstation may need an individual assessment. The UK Health and Safety Executive says DSE requirements can apply to permanent, long-term and hybrid home workers.
If you want one or two more screens, check your laptop model’s display support, ports and required cables before choosing a monitor or dock. Apple Support notes that a Mac’s supported display count also depends on the displays’ resolution and refresh rate.
If an employer’s DSE assessment identifies a need for equipment, establish how it will be provided before buying it yourself. The Health and Safety Executive says workers cannot be charged for equipment the employer provides when the assessment indicates action is needed.
Decide what needs to change at the desk, then check the laptop connection and any DSE assessment outcome before selecting equipment.
| Priority | What to check | Your needs |
|---|---|---|
| Workstation fit | Consider the screen and input devices alongside the desk arrangement and work conditions. For UK workers covered by DSE requirements, use the individual workstation assessment to identify needed changes, as advised by the Health and Safety Executive. | I use my laptop at home for sustained work and want to address what is unsuitable in my actual setup, rather than buy the same accessories as everyone else. |
| Screen connection | Check the exact laptop model’s external-display count, video-capable ports, supported resolution and refresh rate, and the cable or adapter. Apple Support says Mac display limits vary by model and display settings; a USB-C connector alone does not establish video capability. | One more screen would give me room for several windows, but I need to know whether my laptop can drive the monitor I choose. |
| Position and inputs | If the laptop remains your only display, consider whether its position and built-in keyboard and trackpad suit the workstation. Check whether a stand and separate keyboard and mouse address the assessed need; they do not add screen space. | I may only need to reposition my existing screen and use separate input devices, rather than add another display. |
| Docking | Compare the connections you will use, then check the dock’s host protocol, display limits, cable path, charging arrangement and system requirements. The USB Implementers Forum says USB4 connections operate at the devices’ best mutual capability. | Connecting displays and several desk devices together would simplify how I move my laptop, provided the dock works with its ports and display limits. |
| Who provides it | Ask whether a UK employer’s DSE assessment identifies equipment as necessary. The Health and Safety Executive says workers cannot be charged when the assessment indicates action such as employer provision of DSE equipment. | Before paying for work equipment myself, I want to distinguish an optional upgrade from something my employer’s assessment says is needed. |
The connector shape does not establish the laptop’s video capability or supported number of external screens. Apple Support ties display support to the Mac model and connected displays, while the USB Implementers Forum describes USB4 capability as dependent on both ends of a connection.
Look up the exact laptop model’s display specification and check the monitor or dock, cable and adapter against it before ordering.
An incompatible cable or adapter may need replacing.
For a UK worker, the funding decision changes if an employer’s DSE workstation assessment indicates action is needed. The Health and Safety Executive says the worker cannot be charged for equipment the employer provides in that situation.
Ask whether an assessment has identified the proposed equipment as necessary before treating it as a personal upgrade.
A dock’s available display modes depend on the host connection as well as the connected screens. Lenovo’s compatibility information for its ThinkPad Universal Thunderbolt 4 Dock, for example, specifies requirements for the laptop’s Type-C connection.
Check the intended laptop, dock and displays together for the required display count, resolution, refresh rate and connection standard.
Dell advises updating the system BIOS, graphics drivers and dock drivers before using its WD22TB4 because older versions can affect recognition or operation.
Read the support instructions for the exact dock and laptop, and allow time to complete required updates during setup.
Updates and troubleshooting can take time if the dock is not recognised.
These manufacturers’ documentation helps illustrate what to verify for a particular laptop and connection; a brand name alone does not establish compatibility.
Relevant when considering the ThinkPad Universal Thunderbolt 4 Dock for a laptop workstation.
Relevant when evaluating the WD22TB4 dock for external displays and desk peripherals.
Relevant to Mac users selecting a monitor, cable, adapter or dock.
Relevant to Surface users choosing an external-display connection or dock.
These options cover external monitors and a USB-C dock for laptop-based desk setups. Choose by the screen or connections you need, then confirm compatibility with your own laptop.

For a fixed desk where a larger external display is wanted, this monitor’s title specifies 3840 × 2160 resolution and Type-C 65 W. Check the laptop’s supported display mode and whether 65 W meets its charging requirements.

An IPS WQHD external-display option for a desk-based laptop setup. If you plan to connect or charge through USB-C, confirm the laptop’s video capability and charging requirements against the monitor’s connections.

Consider this dock when two HDMI connections and a shared desk connection suit your setup. Its title specifies 100 W power-delivery pass-through, not a guarantee of charging for every laptop; check the host’s video support, intended display modes and power requirements.

A second-display option to consider when moving between home and another work location. Confirm that the laptop supports the video connection required for this model before choosing it.

For a larger fixed desk display, the product title identifies a 31.5-inch IPS screen and built-in speakers. Check the intended resolution and refresh rate through your laptop’s chosen video connection, as well as whether the stand suits your desk position.
Not solely because you work from home. The Health and Safety Executive says the requirements can apply to permanent, long-term and hybrid home workers who use DSE daily for continuous periods of an hour or more; it distinguishes occasional or short periods of home DSE use.
Ask about your DSE workstation assessment if the equipment may be needed for your work setup. For UK workers, the Health and Safety Executive says an employer cannot charge a worker for equipment it provides when the assessment indicates action is needed. An optional personal upgrade is a separate decision.
No: check the exact laptop model’s supported display count, video-capable port, dock requirements, displays and cable path. Apple Support describes model- and display-dependent limits, and the USB Implementers Forum says USB4 connections use the best mutual capability of connected devices.
Match its display modes, host connection and charging arrangement to your laptop and screens, then check its setup requirements. Dell, for example, advises BIOS, graphics-driver and dock-driver updates before using the WD22TB4.
Use Windows display settings to identify and arrange the screens to match their positions on your desk. If a connected display does not appear, Microsoft Support directs users to Settings > System > Display > Multiple displays > Detect.
