Choose a monitor around the work you need to see, then compare its full screen-and-stand dimensions with your desk. Before choosing a one-cable monitor, adapter or dock, check your exact laptop’s video output, external-display limit and charging needs; a larger screen or extra connector cannot overcome an unsupported setup.
If you need documents, reference material or a call visible alongside your main task, start with what you want on screen and check the laptop’s display output against the monitor’s inputs. Which? covers monitor choices for work and home offices, including screen size and connections.
If your desk also needs to accommodate a laptop and input devices, check the screen and stand footprint as well as the diagonal size. Which? discusses smaller displays for limited spaces, while Samsung’s home-office guidance highlights available desk space as a factor in choosing screen size.
If you regularly connect peripherals or plan to use more than one external screen, check the ports, charging arrangement and supported display count for your exact laptop. Apple Support notes that external-display support depends on the device’s specifications.
Start with the material you need visible, then check the full desk footprint and the laptop’s supported connection before choosing an adapter or dock.
| Concern | What to check when buying | Who this matters to |
|---|---|---|
| Usable workspace | Compare resolution, preferred text scaling and the windows you want visible. | When I need documents or reference material open alongside my main task, usable workspace comes first; around 33% of consumers prioritise that need. |
| Desk fit | Measure the available width and depth, then compare them with the monitor and stand dimensions. | If my desk must also fit a laptop and keyboard, I need to account for the complete footprint; around 25% of consumers put desk fit first. |
| Connection and charging | Check the exact laptop’s video-capable output, display limit and power needs against the monitor and any cable, adapter or dock. | I want a video connection that works with my laptop and, if needed, can charge it too; around 25% of consumers prioritise connection and charging. |
| Screen positioning | Check the supplied stand’s adjustments; for an arm, confirm monitor mounting, supported weight and desk attachment. | If I need to position the screen to suit my workstation, I’ll check the stand or a compatible arm; around 17% of consumers put positioning first. |
The screen’s diagonal does not tell you whether its stand will fit alongside your laptop and input devices or let you place the panel where you need it.
Measure the desk and compare its usable space with the complete monitor-and-stand dimensions before ordering.
If the supplied stand takes up needed working area, you may need a compatible arm or a different display.
The laptop, monitor and cable must all support the functions you intend to use; a matching connector shape alone does not establish that.
Check the exact laptop model’s video output and power needs against the monitor and the complete connection path.
A different compatible cable, adapter or charging arrangement may be needed.
The number of sockets on a dock does not establish how many external displays your laptop supports.
Check the laptop’s supported display count and the dock’s documented compatibility before buying.
If a dock cannot provide the intended arrangement, it may need replacing.
The 27E1N1600AE/00 is an example to consider if you are looking at a QHD screen with USB-C power delivery for a laptop connection.
The P2425HE illustrates a 23.8-inch Full HD USB-C hub monitor with other video inputs.
The ThinkVision T24m-29 is a 23.8-inch Full HD example for a desk where video, data and power through USB-C are being considered.
HP’s Series 5 Pro listings include 23.8-inch Full HD and 27-inch QHD USB-C monitor variants, offering different screen-size options to assess.
The GW2490 is an option to investigate for a straightforward additional display for home working.
These Joybuy listings are monitors and portable screens to consider for adding display space to a laptop-based home-working setup. Check each screen’s dimensions and the laptop’s supported connection before choosing.

A 26.5-inch screen option to assess against your available desk space and laptop’s supported video output.
The listing names a QD-OLED panel and 2560 × 1440 resolution.

A portable-screen option to assess if a separate screen that can be moved between work areas suits your setup.
The listing specifies a 15.3-inch IPS display, 1920 × 1200 resolution, 60 Hz and a weight of 1.2 kg.

A portable display to consider if a second screen for a laptop needs to fit a smaller working area.
The listing specifies a 15.6-inch FHD 1080p IPS display, USB-C and HDMI connections, a smart-cover stand and VESA mounting.

A very wide-screen option to consider for side-by-side work only if its full dimensions suit your desk.
The listing specifies a 5120 × 1440 DQHD display, 32:9 aspect ratio, 165 Hz, HDMI and DisplayPort inputs, and a 75 × 75 VESA mount.
Do not assume it will. Check your exact laptop’s video-output specification, the monitor’s USB-C video input, the cable and the available power against your laptop’s charging requirement. Microsoft Support notes that USB-C cables do not all support the same features.
Not necessarily; it depends on the laptop model and dock. Apple specifies one native external display for the 2020 M1 MacBook Air, while its M5 MacBook Air specifications describe support for up to two. Check the specifications for your exact laptop and the dock’s supported arrangement rather than counting its display sockets.
The Health and Safety Executive advises placing the screen directly ahead, with its top around eye level and approximately an arm’s length away. Its guidance also suggests a separate keyboard and mouse for prolonged laptop use so the screen can be raised; adjust the arrangement to your workstation.
No particular monitor model is specified in the cited Health and Safety Executive guidance. It says employers must assess workstations when workers use display-screen equipment daily as normal work, continuously for an hour or more; its home-working guidance says the assessment informs whether additional equipment is needed.
For applicable UK online purchases, GOV.UK says consumers must be told they can cancel up to 14 days after delivery without giving a reason. Check the seller’s cancellation instructions, and distinguish a change-of-mind cancellation from a claim about a faulty or misdescribed monitor.
