Laptop users adding a second screen
If documents, calls and other windows compete for space on a laptop, consider an external display alongside the connection and desk space it requires.
Who is this setup for?
People seeking a one-cable desk
A USB-C monitor may combine video and laptop charging, but only when the laptop, monitor and cable support the required functions. Check the exact laptop model before relying on that arrangement.
Home workers adjusting screen position
If the current screen cannot be positioned comfortably, consider stand adjustment or a compatible arm as part of the whole workstation. The Health and Safety Executive advises considering equipment, furniture and working conditions together.
What should you check before buying?
Start with the laptop's video output, then compare the screen's footprint and adjustment options with the desk where you will use it.
| Priority | What to check | Your needs |
|---|---|---|
| Screen space | Compare screen size and resolution separately. Measure the available desk width and depth; consider how much document or application content needs to be visible. | I need room for documents and calls, but the screen also has to fit my desk. |
| Laptop connection | Identify the laptop's video output and the monitor's input. For USB-C, confirm the supported video mode, charging requirements and cable; for HDMI or DisplayPort, check the ports and any adapter. Microsoft and Apple both advise checking the connection components and port type. | One cable would simplify my desk if my laptop supports both display output and the charging arrangement. Otherwise, a matching video cable and separate laptop charger may suit me. |
| Screen position | Check the stand's stated height and angle adjustments. If considering an arm, confirm its compatibility with both monitor and desk. The Health and Safety Executive says a workstation assessment considers equipment, furniture and work conditions together. | My screen needs to sit comfortably at this desk; adjustment matters more to me than size alone. |
| Work equipment | Check the employer's display-screen-equipment assessment process before self-funding equipment for qualifying work use. The Health and Safety Executive says employers must assess workers who use display screen equipment daily for continuous periods of an hour or more as part of normal work; workers cannot be charged for equipment the assessment identifies as needed. | I use a screen for sustained work at home and want to establish whether my employer's assessment calls for a change to my setup. |
What can go wrong?
-
Assuming every USB-C port does the same job
A USB-C connection does not, by itself, establish that the laptop can send video through it or use the monitor's charging and hub functions. Microsoft notes that the PC, cable, dock or port can limit a USB-C display connection.
Check the exact laptop's external-display mode and charging requirements against the monitor and cable specifications.
-
Choosing screen size without planning its position
A display still needs to fit the desk and be positioned for the person using it. The Health and Safety Executive advises assessing the whole workstation rather than treating one screen feature as the answer.
Measure the desk and check the stand's adjustment range. For a separate arm, confirm the monitor mount and desk attachment requirements.
-
Buying work equipment before checking employer arrangements
For qualifying display-screen-equipment users, an employer assessment may identify changes to the home workstation. The Health and Safety Executive says workers cannot be charged for equipment that assessment identifies as needed.
Ask how your employer handles home-working assessments and equipment provision before paying for a monitor specifically for work.
-
Treating similar model numbers as identical
A model suffix can distinguish the connection and stand configuration relevant to your purchase. Dell's P2425HE USB-C hub specifications do not establish the features of a P2425H listing.
Match the complete manufacturer model number and check its stated ports, charging and stand details on the exact listing.
Relevant brand examples
These manufacturer examples illustrate features to compare on exact models, not features shared by every monitor from a brand.
Dell
Dell UK lists the P2425HE as a 23.8-inch Full HD USB-C hub monitor for a laptop desk.
- The P2425HE specification lists up to 90W power delivery and height, pivot, swivel and tilt adjustment, including up to 150 mm of height adjustment.
- Check the full model suffix and the laptop's connection and charging requirements; these P2425HE specifications do not apply to every Dell monitor.
AOC
AOC UK specifies a 27-inch, 3840 × 2160 display for the U27E4CV.
- For this model, AOC lists a height-adjustable stand and USB-C docking with DisplayPort Alternate Mode and 90W power delivery.
- Check that a 27-inch screen fits the desk and that the laptop supports the required USB-C video and charging arrangement.
BenQ
BenQ UK presents the GW2490TC as a home-office display with screen-comfort controls and workday reminders.
- BenQ lists Low Blue Light and Flicker-Free features, plus Eye-CareU break reminders, for this model.
- Those features do not replace breaks or appropriate workstation positioning; check the exact model's connections and adjustment options separately.

ASUS ProArt PA24ACRV IPS QHD
For a home desk needing a separate work screen, compare this QHD IPS model's dimensions with your available space. Confirm its inputs, stand adjustment and your laptop's video output before choosing a connection.

ASUS ProArt PA248CRV IPS WUXGA
If document space is a priority, compare this WUXGA IPS display's format and physical size with your current screen and desk. Check the exact model's inputs and stand, along with the laptop's supported display connection.

ASUS ProArt PA248CNV IPS WUXGA
This WUXGA IPS model is another option for a laptop desk where document layout matters. Compare its exact connection and stand specifications with your laptop and working position; do not assume it has the same configuration as the PA248CRV.

ASUS ProArt PA278CV IPS WQHD
For a desk where a larger work display is being considered, check this WQHD IPS model's actual dimensions before ordering. Verify the laptop connection and, if you plan to charge through the monitor, its power-delivery specification against the laptop's requirements.

ASUS ZenScreen MB166C 15.6-inch Full HD portable USB monitor
A portable second screen may suit a workspace that changes location. This model's name specifies a 15.6-inch Full HD IPS display and USB Type-C; confirm your laptop's video and power compatibility, plus the screen's actual weight and included power arrangement if you plan to move it regularly.
Common questions
Should I buy my own monitor for home working in the UK?
Check your employer's display-screen-equipment process first if you use a screen daily for continuous periods of an hour or more as part of normal work. The Health and Safety Executive says employers must assess those workstations and workers cannot be charged for equipment the assessment identifies as needed.
Will any USB-C monitor work with my laptop through one cable?
No: the laptop must support the required video output, and its charging needs must match the proposed setup. Microsoft warns that the PC, cable, dock or port can limit USB-C functionality, so check the exact laptop and monitor specifications before relying on one cable.
When should I use HDMI or DisplayPort instead?
Use an HDMI or DisplayPort connection when the laptop and monitor have compatible ports, or when a suitable adapter is confirmed for the exact devices. Apple advises identifying the computer port correctly before selecting a cable or adapter; plan separately for laptop charging if the video connection does not provide it.
Is an adjustable stand enough to fix an uncomfortable desk setup?
Not necessarily. An adjustable stand can help place the screen, but the Health and Safety Executive says a workstation assessment should consider equipment, furniture, working conditions and individual requirements together. Check whether the stand's range actually works at your desk.
Can I use a similar model number to check monitor features?
Check the complete model number instead. Dell UK specifies USB-C hub functions for the P2425HE, but that does not establish the same features for a P2425H listing. Match the exact suffix and verify the ports, stand and charging details that matter to your setup.
