Choose a fixed monitor if you mainly work at one desk and need more room for documents, spreadsheets or side-by-side applications, with screen positioning that suits longer sessions. A portable screen makes more sense when the extra display needs to travel, but check your laptop’s video output, monitor input, cable type, charging needs and supported display count before buying.
For people who routinely work at one desk with spreadsheets, documents, browser windows or meetings open together and can benefit from a separate display positioned directly in front of them at an appropriate height. The Health and Safety Executive advises placing the top of the screen around eye level and roughly an arm’s length away.
For people who move between home, another workplace or a study location and need an additional display that can travel with the laptop. The Office for National Statistics reported that 28% of working adults in Great Britain hybrid worked between January and March 2025; a portable monitor is useful only when that extra mobility is needed.
For users whose laptop supports external video through USB-C and who want one compatible cable for display data and, where both devices allow it, charging power. Confirm the exact capability for the laptop, monitor and cable combination.
Choose it when: Your laptop normally stays at one desk and you regularly work across documents, spreadsheets, meetings or creative tools.
Trade-off: It needs permanent desk space and mains power, and one-cable charging works only with compatible laptop video output and sufficient monitor power delivery.
Choose it when: You work across several locations and mainly need a second view for a document, chat or reference window.
Trade-off: A portable 15.6-inch Full HD display is easier to carry but provides less physical workspace than a desktop monitor.
Choose it when: Your laptop and monitor use different video ports, or you need more connections than the laptop provides.
Trade-off: A dock or adapter adds another compatibility point, so its supported resolution, refresh rate and display count need to match the laptop.
| Priority | What to check | Your needs |
|---|---|---|
| Workspace for parallel tasks | Compare screen size and resolution; QHD is 2560 × 1440. Check whether desk depth and operating-system scaling suit the display. | I want room to keep a document, meeting or chat visible while working in another window. A portable 15.6-inch Full HD screen adds a second workspace, while a fixed QHD monitor suits a more permanent desk. |
| Connection and charging compatibility | Check the laptop’s video output, monitor input and cable type. Confirm USB-C video support, power delivery and the laptop’s supported external-display configuration. | I want the monitor connection to match my actual laptop ports without relying on the USB-C connector shape alone. A compatible dock or adapter can help where ports differ. |
| Ergonomic placement | Check height adjustment, tilt, swivel and pivot where relevant. Measure desk depth and allow space for a separate keyboard and mouse for prolonged laptop use. | I need the screen centred and positioned for my seating rather than forcing me to look down at the laptop display. The Health and Safety Executive advises keeping the screen directly in front, with its top around eye level. |
USB-C can carry different functions, and a laptop’s external-display capability is model-specific. DisplayPort Alt Mode is one video route used through USB-C, but the connector alone does not confirm that it is available.
Check the laptop manufacturer’s specifications for supported external displays, USB-C video capability, charging input and maximum display configuration before choosing a USB-C-only monitor or dock.
You may need a replacement cable, adapter or dock if the laptop’s USB-C port does not support the required video mode.
A larger display does not automatically create a comfortable setup. The Health and Safety Executive advises placing the screen directly in front, with the top around eye level and about an arm’s length away.
Measure desk depth and height first. Prioritise a height-adjustable stand or plan for a compatible VESA arm, then consider whether you also need an external keyboard, mouse or laptop riser.
An external keyboard, mouse, laptop riser or monitor arm may be needed for a workable prolonged-use setup.
Microsoft notes that adapters and docks can cause connection conflicts, while a laptop’s graphics adapter can limit the number of monitors it supports. A splitter duplicates a signal rather than extending it into an independent desktop.
Confirm the laptop’s supported display count, resolution and refresh rate, then choose a dock or adapter with matching documented capabilities.
A non-compatible dock or splitter can result in a duplicated display setup and require a replacement purchase.
A portable 15.6-inch Full HD monitor can be useful as a second screen, but it is not equivalent to a larger fixed QHD monitor with a fully adjustable stand.
Choose portable only when moving the display is a recurring need. For frequent spreadsheets, side-by-side documents or an all-day home desk, compare fixed QHD monitors with height adjustment first.
Dell’s UK business-oriented monitor range includes the P2425DE, a 23.8-inch QHD USB-C hub monitor with a fully adjustable stand.
BenQ’s UK GW2790QT is a 27-inch QHD USB-C ergonomic monitor for work-and-home use with an integrated USB hub.
Lenovo’s L15 is a portable 15.6-inch Full HD monitor for an extra display that can travel rather than a permanent desktop monitor.

A portable second-screen route for hybrid work, travel or changing study spaces.
15.6-inch Full HD IPS display; 780 g weight; 11.8 mm thickness; USB-C DisplayPort Alt Mode connection for power and video.
It provides less physical workspace than fixed QHD or 4K monitors and requires a USB-C source with DisplayPort Alt Mode for the stated one-cable setup.
No. Check the laptop manufacturer’s specifications for external-display support, including USB-C DisplayPort Alt Mode, USB4 or Thunderbolt capability where applicable. VESA identifies DisplayPort Alt Mode as a USB-C video transport, but monitor support and display limits remain device-specific.
It can when the laptop supports video over that USB-C connection, the monitor provides USB-C power delivery and the available power suits the laptop. BenQ lists up to 65W for the GW2790QT and Dell lists a 90W power-delivery option for the P2425DE; these are model-specific figures.
Choose a portable model when you need an extra screen across several locations and a 15.6-inch Full HD workspace is enough for a reference document, chat or second application. Choose a fixed monitor when the setup stays at one desk and ergonomic placement, larger screen area or QHD resolution matter more than portability.
No. Microsoft states that a display splitter duplicates the same signal rather than creating two independent signals. For separate external displays, check the laptop’s graphics and display-adapter specification, then use compatible independent video outputs or a suitable dock where supported.
The Health and Safety Executive states that the Display Screen Equipment Regulations apply to workers who use display screen equipment daily for continuous periods of an hour or more, including home workers, fixed-workstation users and mobile workers. Where the regulations apply, employers must assess workstations and reduce risks; this does not mean every consumer is legally required to buy an external monitor.
