Choose a second screen by checking the computer’s video output before settling on a size: an HDMI or DisplayPort monitor needs a compatible output, while a USB-C monitor can combine display and charging only if the laptop supports video over USB-C and the monitor supplies enough power. For sustained desk work, check that the screen and its stand or mount fit the desk and can be positioned comfortably.
If documents, spreadsheets, email and browser windows compete for space on a laptop, an additional display gives you another place to arrange them. Which? identifies size, resolution, ports and adjustment as relevant checks when choosing a work monitor.
A USB-C monitor may suit a laptop desk where one connection for the display and charging matters. Check the laptop’s video-output capability and charging needs first: BenQ explains that USB-C monitor video requires a compatible display mode, not just a matching socket.
If the laptop and second screen would make you turn repeatedly or look at an awkward height, positioning matters as much as panel size. The Health and Safety Executive advises placing the screen directly in front of you, with its top around eye level and the screen roughly an arm’s length away.
Start with the space needed for your work, confirm how the computer will drive the display, then check whether the complete setup can be positioned on your desk.
| Concern | What to check | Who this matters to |
|---|---|---|
| Readable workspace | Compare panel size and native resolution with the available desk space; check the stand’s footprint. | When documents and spreadsheets need to stay visible together, I want more usable space without crowding my desk. Around 42% of consumers would put workspace first. |
| Connection and charging | Confirm the computer’s video-capable ports and external-display support; for USB-C, check video capability and power-delivery wattage against the laptop’s requirements. | I want an independent second desktop and, if possible, fewer cables at my laptop desk. For roughly 33% of consumers, a compatible connection is the primary concern. |
| Screen position and desk fit | Check the stand’s adjustment range or a mount’s compatibility with the desk, alongside the position of the keyboard and laptop. | During long work sessions, I need to see the screen without twisting or setting it at an awkward height. Comfortable positioning comes first for around 25% of consumers. |
A matching connector does not establish that the laptop can send a display signal. BenQ explains that USB-C monitor video uses DisplayPort Alt Mode.
Check the exact laptop model’s external-display specifications before relying on a USB-C connection for video.
A screen that cannot be placed appropriately may leave you looking up, down or sideways during work. The Health and Safety Executive advises a central position, with the top of the screen around eye level and the display roughly an arm’s length away.
Check the included stand’s adjustments against your desk and chair arrangement before ordering.
If the stand cannot reach the needed position, a compatible arm or riser may be needed.
Microsoft says a display splitter duplicates a signal rather than creating two independent displays.
If you need separate workspace on each screen, check the computer’s supported external-display count and the capabilities of any dock, then use Extend mode.
The positioning offered by a clamp or grommet stand depends on being able to install it on the desk. LG’s 27QN880, for example, uses this type of mounting arrangement.
Check the desk edge or grommet position, available clearance and the instructions for the exact stand.
Dell’s Pro and P-series ranges include conventional desk monitors. The Pro 24 Plus QHD P2425D is a 23.8-inch example for a workspace where a smaller panel and stand adjustment matter.
LG’s Ergo range is relevant where the screen needs to move around a constrained desk. The 27QN880 pairs a 27-inch QHD panel with a clamp or grommet stand.
BenQ’s home-office range includes USB-C monitors for laptop desks. The 27-inch GW2786TC is an example with connections for peripherals and an adjustable stand.
These displays offer different sizes and connection options for adding a screen to a home workspace. Choose against your computer’s outputs, desk space and positioning needs rather than panel size alone.

Consider this curved display if your desk can accommodate a screen in this size range for document and multi-window work.
The product name specifies 3840 × 2160 resolution, USB-C with 65W power delivery and a USB hub. Confirm that its USB-C connection supports video from your laptop and that 65W meets your charging needs.

Consider the MB249C if your home or hybrid workspace calls for a second screen that can be repositioned; check which mounting arrangement suits your desk.
It has an IPS panel and USB-C connectivity. Confirm the laptop’s USB-C video support, the monitor’s charging suitability and which accessories are included.

This 31.5-inch screen is worth considering when a larger physical panel fits the desk and your document layout.
The product name identifies an IPS panel and built-in speakers. Check the video input you intend to use and whether the supplied stand can position the screen comfortably.

A portable screen may suit a work area that needs to be moved or packed away.
This UPERFECT model is identified as an 18.4-inch, 3840 × 2160 QLED display with USB-C, Mini HDMI and VESA mounting. Confirm the required video connection and how the screen will be supported on your desk.

Consider this 49-inch screen only if your multi-window work calls for a very wide display and the desk can accommodate it.
The product name specifies a 32:9 panel, two HDMI 2.1 inputs, two DisplayPort 1.4 inputs and VESA 75 × 75 mounting. Confirm the supplied stand’s actual adjustment range, and check the desk or mount’s load suitability before ordering.
No: the connector alone does not confirm video output. BenQ explains that USB-C monitor video uses DisplayPort Alt Mode, so check the specifications for your exact laptop and the monitor connection you plan to use.
No: Microsoft says a splitter duplicates the same display signal rather than creating two independent signals. Check how many external displays the computer supports, then use Extend mode for separate workspace.
Position the screen you use most directly in front of you, with its top around eye level and the display roughly an arm’s length away, as advised by the Health and Safety Executive. For prolonged laptop use, a separate keyboard and mouse allow the laptop screen to be raised as part of the setup.
Only if the monitor’s power delivery meets the laptop’s charging needs during your intended use. Compare the ratings for the exact models: LG specifies up to 60W for the 27QN880, while BenQ specifies up to 65W for the GW2786TC.
