Start with the workstations you use and your laptop’s exact ports, charging requirement and external-display limit. A raised laptop with a separate keyboard and mouse may be enough if you do not need another screen; add a monitor for more display space, or consider a hub monitor or dock when you need to reconnect compatible displays and peripherals. If you are covered by a display screen equipment assessment at work, check its outcome before choosing equipment for home.
If you work for extended periods on a laptop, consider whether its screen position and built-in controls suit your desk. The Health and Safety Executive (HSE) advises using a separate keyboard and mouse when raising a laptop screen; a separate display is another arrangement to consider.
If you connect screens and wired accessories each time you sit down, a hub monitor or dock may reduce separate connections. Check the exact laptop’s video-capable ports and display limit before choosing either route; Apple says Mac display connections depend on the model’s ports.
In Great Britain, HSE says employers must assess workstations for employees who use display screen equipment (DSE) daily as part of normal work, continuously for an hour or more. Where they use DSE at home and in the office, the assessment should cover both settings.
Decide how the screen and input devices will sit on each desk, then check what your laptop can connect and power before choosing a monitor or dock.
| Priority | What to check | Your needs |
|---|---|---|
| Workstation arrangement | Check screen position, keyboard and mouse placement, and the arrangements at both work locations. For relevant Great Britain employees, HSE says the DSE assessment should cover home and office where both are used. | I use a laptop for sustained work and need the screen and controls positioned for each desk, rather than choosing an accessory in isolation. |
| Port compatibility | Identify the laptop’s video-capable ports and the monitor’s or dock’s required connection. Check the cable and protocol too: Microsoft notes that USB-C functions can vary with the PC, accessory, cable and software. | A matching USB-C connector is not enough for me if it cannot provide the video or other functions my setup needs. |
| External displays | Check the laptop model’s maximum external-display count at the intended resolution and refresh rate, then compare its outputs with the screen inputs or dock outputs. Apple says Mac display support depends on its ports and model specifications. | If I want two external screens, I need to confirm that my laptop supports that arrangement—not just that a dock has two outputs. |
| Charging and connections | Compare the laptop’s original charging requirement with power delivered through the proposed monitor or dock. List the USB devices and Ethernet connection you want to leave at the desk; Dell specifies different WD25Z charging levels for Dell and non-Dell systems. | I would like fewer connections to make each day, but the chosen device still has to meet my laptop’s charging and peripheral needs. |
| Desk space and mobility | Check the screen’s dimensions and adjustment options against the available desk space. If you carry a second screen between locations, consider its listed size, weight and required connection. | A fixed desk can accommodate a different screen arrangement from the one I am willing to carry between home and office. |
Two dock outputs do not establish that the laptop can run two external screens at the resolution and refresh rate you want. Apple says a hub or daisy chain does not increase a Mac’s maximum supported display count.
Check your exact laptop model’s display limits and video-capable ports against the dock’s requirements before buying.
A connector can fit while video, charging or other functions remain unavailable. Microsoft notes that the PC, dock, cable and software combination can affect USB-C functionality.
Confirm the required USB-C video protocol and cable specification for the exact laptop and accessory.
Moving the screen also moves the attached keyboard and trackpad. HSE advises a separate keyboard and mouse when a laptop is raised on a riser or similar support.
Plan space for those input devices and check how the whole arrangement fits the desk.
For employees covered by the Great Britain DSE assessment requirements, the assessment concerns the workstation, not just a proposed monitor. HSE says it should cover both home and office where both are used.
Ask your employer about the assessment and its outcome before choosing equipment for a long-term home-work setup.
Dell’s P2425E hub monitor and WD25Z dock illustrate two different approaches to connecting a regular laptop desk.
Lenovo’s USB-C Dual Display Travel Dock is a reference point for a compact dock when the desk already has displays.
For a Mac-based setup, the exact computer model matters when selecting an external screen or dock.
These options include external screens for a regular or portable desk and a dock for reconnecting displays and peripherals. Check each against your laptop and the space where you will use it.

An external-screen option for a regular laptop desk. Check the monitor’s USB-C video function and power-delivery wattage against your laptop before relying on it for a single-cable connection.

Consider the space a curved screen needs on a regular desk. The product name lists 4K resolution, 165Hz, a USB hub and Type-C 65W; confirm your laptop supports the intended video connection and that the stated charging output meets its requirement.
No image available
A dock to consider when you reconnect two HDMI displays at a desk. Check your laptop’s USB-C Alt Mode and external-display support; also confirm whether the external 100W+ adapter specified for the setup is included and whether delivered charging meets your laptop’s needs.
No image available
A separate-screen option for a desk where a 24-inch display fits. The product name lists HDMI, DisplayPort and VGA; confirm the connection you intend to use. Check the refresh rate before buying because the listed details conflict between 100Hz and 60Hz, and confirm any required USB-C video or charging function separately.
No image available
A second-screen option to consider when you move between work locations. Check that your laptop’s USB-C port supports DisplayPort Alt Mode for the intended connection; HDMI is listed as unsupported for this model.
In Great Britain, HSE says employers must carry out a workstation assessment where employees use DSE daily as part of normal work, continuously for an hour or more. If you use DSE at home and in the office, the assessment should cover both settings.
No. A USB-C connector alone does not establish video capability or support for two external displays. Microsoft notes that the PC, dock, cable and software combination can limit functions, while Lenovo specifies USB-C Alt Mode or Thunderbolt support for its Dual Display Travel Dock. Check your exact laptop’s port protocol and display limit.
No. Apple says a hub or daisy chain does not increase a Mac’s maximum external-display count. Check your exact Mac model’s display specifications at the resolution and refresh rate you intend to use.
HSE advises using a separate keyboard and mouse so the laptop screen can be raised on a riser or similar support. A separate display is another option for prolonged laptop use; check how the screen and controls will fit on your desk.
No. Northern Ireland has its own DSE regulations and Health and Safety Executive for Northern Ireland (HSENI) guidance. HSENI says its rules can apply to permanent, long-term and hybrid home workers who use DSE daily for an hour or more at a time; check the Northern Ireland guidance and your employer’s procedure.
