A separate monitor makes sense at a regular desk when you need room for documents or multiple windows and can position the screen alongside a separate keyboard and mouse. A portable monitor suits a second screen that needs to travel, provided your computer supports its video connection. For occasional, short sessions, a laptop screen may be enough; an external monitor adds to your computer rather than replacing it.
The reason to add a display depends on where you work, how long you use the computer and whether the screen needs to move with you.
If documents, browser windows and calls compete for space on your laptop, a separate, positionable screen is worth considering. For prolonged laptop use, the Health and Safety Executive (HSE) advises a separate display, keyboard and mouse as part of the workstation setup.
A portable companion screen may suit someone who needs two displays at different desks. Check the computer’s video output before choosing a USB-C model: Lenovo UK, for example, specifies a compatible USB-C display mode for its ThinkVision M14.
A monitor is only one part of the arrangement. The HSE says UK display screen equipment requirements can apply to permanent or long-term home workers and people who routinely split work between home and the workplace, where they use a screen daily for continuous periods of an hour or more. The workstation assessment considers the setup as a whole.
Consider it when: A regular home desk needs a separate screen for documents and several windows.
Trade-off: It takes permanent desk space and needs power and a compatible connection to the computer or dock.
Consider it when: You need a companion screen at changing work locations rather than one that stays on a desk.
Trade-off: A compact travel screen offers less display area than a full-size desk monitor and still needs a compatible video connection.
Consider it when: Home computer use is occasional or brief and another screen would add little to the task.
Trade-off: For prolonged laptop work, the HSE advises a more considered arrangement with separate input devices so the display can be raised.
Once you know where the screen will be used, check the entire connection path and the space available for a comfortable workstation.
| Priority | What to check | Your needs |
|---|---|---|
| Screen position | Check desk depth, stand or mount adjustment, and room for a separate keyboard and mouse. The HSE advises a screen directly in front of you, with its top around eye level and the display about an arm’s length away. | I use my laptop at a desk for long sessions and want to position the screen without crowding my keyboard and mouse. |
| Video connection | Match the computer or dock’s supported video output, cable or adapter and monitor input. Microsoft Support notes that external-display capability depends on the device model and connection equipment; a USB-C connector alone does not establish video support. | My screen needs to connect to the computer or dock I already use, not merely have a connector that looks right. |
| Screen size | Measure usable desk width and depth, then consider the documents and windows you keep open. Samsung UK’s home-monitor guide discusses 24- to 27-inch displays for everyday tasks and 32- to 34-inch displays for a more expansive workspace. | I want enough room to read and arrange my work while keeping a comfortable viewing distance on my desk. |
| Portable setup | Check carrying size, the stand or mounting arrangement and the host’s required video mode. Lenovo UK specifies USB-C DP1.2 Alt Mode and PD2.0 compatibility for the 14-inch ThinkVision M14; other models have their own requirements. | A second screen would be useful when I change locations, but I still need it to work with my laptop. |
| USB-C charging | If you want one cable for video and laptop charging, check both the host’s display capability and the monitor’s stated power delivery against the laptop’s requirements. Confirm that the intended cable supports the setup. | I would like fewer cables at my desk, but charging the laptop through the monitor has to meet its needs. |
A connector that fits does not establish that the computer, dock, cable and monitor support the same display and charging functions. Microsoft Support notes that external-display capability depends on the device and connection equipment.
Check the exact computer or dock model’s video-output documentation, then compare it with the monitor input, cable requirements and stated power delivery.
Getting the connection wrong may mean changing the cable, adapter or dock to achieve the intended setup.
A larger panel still has to fit at a usable viewing distance, with space for input devices. The HSE advises placing the screen directly in front of you, with its top around eye level and the display about an arm’s length away.
Measure desk width and depth before ordering, and check whether the supplied stand or a suitable mount can put the screen where you need it.
If the stand cannot provide the required position, a compatible monitor arm or a different desk arrangement may be needed.
A separate display can help with screen placement, but the keyboard, mouse, chair and desk remain part of the workstation. The HSE’s guidance for prolonged laptop use addresses the display and separate input devices together.
Plan the whole arrangement. If you are an employee whose home workstation falls within UK display screen equipment requirements, use your employer’s assessment process rather than treating a monitor as the only change.
A compact companion display and a fixed monitor serve different space and carrying needs. Lenovo UK’s 14-inch ThinkVision M14, for example, is a smaller screen than the fixed 27-inch Dell P2725DE listed by Dell UK.
If the screen will usually stay at one desk, compare usable display area, positioning and connection requirements with a fixed monitor before prioritising portability.
These manufacturer examples illustrate different configurations; the specifications below belong to the named models, not every monitor in each brand’s range.
Dell UK lists the Pro 27 Plus P2725DE as a 27-inch QHD USB-C hub monitor for a fixed desk.
BenQ UK presents the 27-inch QHD GW2790QT as a USB-C home-monitor option with an adjustable stand.
LG UK lists the 31.5-inch 4K 32UN880K-B with a C-clamp stand for a fixed workstation where flexible placement matters.
Lenovo UK describes the 14-inch ThinkVision M14 as a mobile companion display for a compatible notebook.
These options include displays for a regular home desk and ZenScreen models to consider when a second screen needs to move between workspaces. Check the exact connection and physical setup for any model before ordering.

The product name identifies the P2425 as a 24-inch monitor. Confirm the exact input ports, refresh rate and included stand adjustments for this variant before relying on them in your setup.
No image available
This portable-screen option suits someone seeking a companion display for work across different locations rather than a permanent desk arrangement.
The product name specifies FHD. Before choosing it, check the laptop’s supported video output, the required cable and whether the screen’s size works for your tasks.
Not necessarily: a laptop screen may be enough for occasional, short sessions. For prolonged laptop work, the HSE advises a separate display, keyboard and mouse as part of a setup that lets you raise and position the screen; an external monitor is also worth considering if a regular desk needs more workspace.
No. USB-C describes the connector, not guaranteed video or charging capability. Microsoft Support says external-display support depends on the device model and cables or adapters, so check the laptop or dock’s video specification, the monitor input, cable capability and any intended power-delivery rating.
Check the video path from computer to dock to monitor, including the dock’s actual outputs, the monitor input and the cable or adapter. Microsoft Support advises checking connections throughout that chain; also select the corresponding input on the monitor.
Choose a size that fits both your desk and the windows you use. Samsung UK’s home-monitor guide describes 24- to 27-inch screens for everyday email, browsing and document work, and 32- to 34-inch screens for a more expansive workspace. Measure usable desk width and depth as well as considering the diagonal screen size.
