Check what external display your computer or tablet supports before choosing the monitor and cable. At a fixed desk, screen space and positioning matter for documents and meetings; colour-sensitive work calls for model-specific colour specifications, while a USB-C connection needs a separate check of video support and charging power.
If documents, spreadsheets and calls need to stay visible together, compare usable screen space with the room available on your desk. Which? notes that smaller monitors can suit limited spaces, while larger displays may suit home-office work.
A USB-C display may simplify connecting at a desk, but the laptop must support video through the chosen port and the monitor must supply enough power if it is also expected to charge the laptop. Apple and Microsoft advise checking display support for the exact device model.
For photo, video or graphics work, match the exact monitor model’s stated colour-space coverage and calibration specifications to the work you produce. A general office display’s resolution alone does not establish colour accuracy.
For a fixed home desk, establish the computer’s display connection first, then weigh screen fit, charging and colour requirements against the work you do.
| Concern | What to check | Who this matters to |
|---|---|---|
| Usable workspace | Measure the desk and stand footprint; compare screen size, native resolution and available stand adjustment. | When documents and meeting windows need to stay open together, I want enough visible space without crowding my desk. Around 31% of consumers put workspace for multitasking first. |
| Connection and charging | Check the exact host model’s display support, the monitor input and, for USB-C charging, the power-delivery rating against the laptop’s requirement. | If I connect a laptop or tablet each day, I need the display connection to work with my device and do not want to rely on inadequate charging. Compatibility is the primary concern for around 31% of consumers. |
| Creative colour work | Match the exact model’s stated colour spaces and calibration specifications to the intended output. | When editing colour-sensitive work, I need specifications relevant to my output rather than assuming that a sharp screen is colour-accurate. Around 23% of consumers place colour requirements first. |
| Footprint and flexibility | Decide whether the screen will stay on the desk or move; check its footprint, stand and required connections. | If desk space is tight or the second screen must move between workspaces, I need a format I can accommodate or carry. Compactness or flexibility comes first for around 15% of consumers. |
The connector shape does not establish how many displays a device can drive or which video configuration it supports. Apple and Microsoft tie external-display support to the exact device and connection hardware.
Check the host model’s display specifications, the intended resolution and refresh rate, and every required port, cable or adapter before ordering.
LG specifies 90W USB-C power delivery for the 27U730A-B but up to 15W for the 27U631A-B. A working video connection therefore does not, by itself, establish that a monitor can replace a laptop charger.
Compare the exact monitor’s power-delivery rating with the laptop’s charging requirement and check which cable is needed.
You may need to keep a separate laptop charger at the desk.
A screen and its stand both need room. Which? distinguishes monitors for limited spaces from larger home-office displays and treats adjustment as a meaningful selection feature.
Measure desk width and depth, including the stand footprint, and check whether the screen can be positioned at a comfortable height and angle.
Declared colour-space coverage and calibration apply to the specified model, not every monitor from the same brand. The relevant colour space also depends on the work being delivered.
Check the exact model’s specifications against your output requirements instead of choosing by resolution or range name alone.
The UltraSharp U2725QE is a reference point for a fixed desk where a 27-inch 4K Thunderbolt hub monitor is being considered.
UltraFine models illustrate why laptop users should compare USB-C charging specifications model by model.
The Creative Pro PD3225U is relevant when a creative workflow calls for particular stated colour spaces.
The ProArt PA279CRV is a model to compare for colour-focused work that also calls for USB-C connectivity.
These monitors are options for a desk-based second screen, with different stated sizes and resolutions. Choose the connection around your computer’s supported output, then check desk fit and any positioning or charging requirements on the exact model.

Consider this 27-inch 4K model when you need a fixed screen for documents or creative work. Check the desk footprint and confirm the connection your computer supports; if you plan to charge a laptop through USB-C, check the monitor’s power-delivery rating against the laptop’s requirement.

For a desk used for creative work, compare this IPS WQHD model’s exact colour specifications with your output requirements. Confirm desk fit and the intended display connection, and check USB-C charging power separately if you need it.

This 4K UHD model is an option for a fixed desk used for documents and study. Check that your computer supports the intended connection and resolution, and confirm whether the stand’s positioning options meet your needs.

A 24-inch FHD screen may be worth considering when desk space matters more than choosing a larger display. Check its footprint, your computer’s display output and whether its stand allows the screen position you need.

Consider the 31.5-inch screen if you have room for a larger fixed display. Measure the desk and stand footprint, and check the stand’s adjustment options and your computer’s display connection before buying.
Check the exact laptop model’s display-support specifications, including its video ports and supported number of external displays. Apple directs Mac users to the model’s port and display-support information; Microsoft says Surface capability also depends on the cable or adapter used.
Only if the monitor supplies power through USB-C at a level suitable for that laptop. LG specifies 90W for the 27U730A-B but up to 15W for the 27U631A-B, so compare the exact monitor rating with the laptop’s charging requirement.
An iPad can connect with a cable or adapter supported by its exact model. Apple describes USB-C display connections for applicable iPads and adapter routes for Lightning models; check the model and the display behaviour you need before buying connection hardware.
Yes: choose a monitor and stand that you can position comfortably on your actual desk, rather than judging fit by screen size alone. The UK Health and Safety Executive’s display-screen-equipment guidance addresses workstation assessment and reducing risks; check the stand footprint and adjustment options as part of your setup.
