Start with your laptop’s video outputs, supported number of external displays and charging requirement, then choose a monitor connection that meets them. HDMI or DisplayPort can provide a direct display connection while you charge the laptop separately; a USB-C monitor can simplify a fixed desk only if the laptop supports video through that port and the monitor supplies suitable power. For two screens or an ultrawide, check the laptop’s display limits and the space available on your desk.
If you regularly connect your laptop at the same desk, a USB-C monitor may handle the display and charging through one cable. Check that your laptop sends video through its USB-C port and that the monitor’s power-delivery output suits your charging needs.
If you compare spreadsheets, documents and meeting windows, decide whether one larger screen, an ultrawide or two external displays fits your work. The desk must accommodate the arrangement, and the laptop must support its intended display output.
If the workspace needs clearing after work, consider the monitor’s footprint, stand, cables and charger alongside screen size. Which? includes kitchen-table use in its monitor guidance; the practical fit depends on the space you have.
Confirm the laptop connection before choosing screen size: a suitable panel will not deliver the intended workspace if the laptop, cable or display arrangement cannot support it.
Choose when: The laptop supports video through the chosen USB-C connection and the monitor’s power output suits your usual charging needs.
Bear in mind: A USB-C socket alone does not establish video support, and a low-power monitor may leave you using the laptop charger.
Choose when: The laptop has a compatible video output or verified adapter route and you are content to charge it separately.
Bear in mind: Display and charging normally need separate cables; confirm that the connection supports your intended display mode.
Choose when: You need a verified way to connect the planned monitor arrangement or additional desk peripherals.
Bear in mind: A dock cannot automatically increase the number of independent displays your laptop supports.
| Concern | What to check | Who this matters to |
|---|---|---|
| Laptop compatibility | Check the exact laptop model’s video-capable ports and supported external-display modes; match the monitor input and cable. | I want the screen to work with my laptop without relying on an unsuitable port or adapter. Around 31% of consumers put connection compatibility first. |
| Usable workspace | Compare screen size and resolution, then consider the text scaling you would use for documents and multiple windows. | When I move between spreadsheets, documents and calls, I need enough readable space to keep the relevant windows in view. For around 38% of consumers, that workspace is the primary concern. |
| Desk fit | Measure desk width and depth with the laptop in place; check stand dimensions and available adjustments. | My shared desk must still be usable when the monitor and its cables are in place. Desk fit comes first for around 23% of consumers. |
| Expanded displays | Check the laptop’s supported external-display count and output modes before planning two independent screens or an ultrawide. | I need a wider layout for several applications, but it has to work as intended through my laptop. Around 8% of consumers primarily prioritise that expanded arrangement. |
USB-C monitors differ substantially in charging output: LG specifies up to 15W for the 27U631A-B and 90W for the 27U730A-B. Neither the connector shape nor a monitor’s USB-C label establishes what your laptop can receive.
Check the laptop’s video-over-USB-C support and charging requirement against the exact monitor’s video, power-delivery and cable specifications.
If the charging output does not suit your laptop, you may need to keep its original charger connected.
Microsoft notes that a display adapter can limit the number of external monitors, while Apple directs users to their Mac model’s display-support specifications. A splitter that duplicates one signal does not provide two independent desktops.
Confirm the exact laptop’s supported number of independent displays and the intended connection method before choosing a second monitor or dock.
A wide screen and its stand need room alongside the laptop. Resolution also affects the pixel workspace, while the text scale you use affects how much of that space is practical for your documents.
Measure the available width and depth, including the stand and cable space, and assess the intended text size before settling on a screen format.
BenQ describes MST daisy-chaining for compatible DisplayPort or USB-C setups and specifies a Thunderbolt route for Mac devices. A monitor’s daisy-chain feature therefore does not establish compatibility with a particular computer.
Check the laptop’s port and display-support specifications, the monitor-chain requirements and the intended resolution before choosing this connection plan.
These examples show why the exact model matters more than the brand name when comparing connections, charging and screen space.
Dell’s UK range includes USB-C hub monitors for fixed desks, including standard-width and ultrawide models.
BenQ’s home-office range includes USB-C monitors with charging and adjustable stands.
LG has UK USB-C monitors with different resolutions and markedly different charging outputs.
Lenovo’s monitor catalogue includes QHD displays and models with USB connections or multi-monitor features.
These monitors cover compact desk screens, a wider single-screen layout and different laptop connection plans. Choose by the screen and desk arrangement you need, then check the exact laptop connection before purchasing.

Consider this USB-C model if you want a screen you can position between work areas. Confirm USB-C video support and suitable charging for your laptop, and check the supplied model’s weight if you plan to carry it frequently.

A choice for one external document-work screen while keeping laptop charging separate. The listed 1920 × 1080 IPS display has a 100Hz refresh rate, with HDMI and DisplayPort among the named connections. Check the exact USB-C functions before planning a one-cable setup.

Consider a single wide panel if you want to arrange several work windows on one screen. This model’s name specifies 3440 × 1440 resolution and 165Hz; measure the available desk space and confirm your laptop can output the intended resolution.
No image available
This 27-inch IPS screen is an option for a fixed work or study space. Its name specifies Full HD resolution and 100Hz; confirm the exact video inputs and the cable or adapter your laptop needs before choosing a connection.
No image available
Consider this larger desktop screen if the desk can accommodate it. The product name identifies an IPS display and built-in speakers; check its exact resolution, stand dimensions and adjustment options against your workspace and laptop output.
Check the exact model’s video ports, supported external-display count and modes, and charging requirement. Apple directs Mac users to their model’s Display Support or Video Support specifications, while Microsoft notes that a display adapter may limit the number of external monitors. Match those details to the monitor input and the cable or adapter you intend to use.
No: USB-C describes the connector, not a guarantee of video output. Check whether your laptop supports a suitable display connection through that port, then confirm the monitor’s video functions, power-delivery output and required cable if you also want charging.
It can reduce the number of connections when your laptop supports video over USB-C and the monitor provides suitable charging through a compatible cable. Charging output varies by model: LG specifies up to 15W for the 27U631A-B and 90W for the 27U730A-B, so compare the exact monitor with your laptop’s charging needs.
A splitter that duplicates one display signal will not create two independent desktops. Microsoft distinguishes duplicated output from support for multiple external monitors; for an extended setup, confirm that the laptop, any dock and the connection method support the two displays you intend to use.
