Choose an external monitor if regular work or study at a fixed desk calls for a separate screen; if the laptop screen is sufficient but needs raising, use a stand with a separate keyboard and mouse. Add a dock, hub or video adaptor only after checking the laptop’s display output and the connections you need. For UK employees covered by display screen equipment (DSE) requirements, the Health and Safety Executive says additional equipment should be decided through an individual workstation assessment.
The useful starting point is how the laptop is used at the desk, not an assumption that everyone needs another screen.
If you work at a home desk for sustained periods, decide whether you need a separate display, a different position for the laptop screen, or both. The Health and Safety Executive advises a separate keyboard and mouse when a laptop is raised for prolonged use and identifies a separate display as another option.
For research, reading and writing at a fixed desk, compare the space available for a monitor with the option of raising the screen you already have. Which? includes home office and study use in its UK monitor buying guidance; those tasks do not, by themselves, establish a need for gaming features.
If two computers use one desk, check how each will connect to the screen. To share a keyboard and mouse as well, look for KVM functionality on the specific monitor model and follow its connection instructions; BenQ describes KVM as a way to switch those peripherals between two connected computers.
Choose when: You need a display separate from the laptop for regular work or study at a fixed desk.
Bear in mind: A monitor does not reposition the laptop’s built-in keyboard or resolve an incompatible video connection.
Choose when: The laptop screen is large enough for your tasks, but you want to position it higher without adding another display.
Bear in mind: A raised laptop needs a separate keyboard and mouse for prolonged use, as advised by the Health and Safety Executive, and does not add screen space.
Once you have chosen the screen arrangement, check connections and desk layout before deciding whether a dock or hub would be useful.
| Priority | What to check | Your needs |
|---|---|---|
| Screen arrangement | Decide whether you need a separate display or to raise the existing laptop screen. Consider where the screen, keyboard and mouse will sit together. | My laptop screen handles the work, but its position at the desk needs changing; or I need a separate screen for the tasks I do regularly. |
| Desk position | Check desk depth and available space. For a monitor, check its adjustment or suitable mounting options; for a raised laptop, allow room for separate input devices. | I need the screen and input devices to fit the desk I actually use, rather than choosing a screen size in isolation. |
| Video connection | Match the laptop’s supported video output to the monitor input and cable or adaptor. Check the laptop’s supported external-display count, resolution and refresh configuration. | A new display needs to work at the setting I intend to use with my particular laptop. |
| Charging and ports | For USB-C video or a dock, confirm the laptop supports the required display mode. Compare any stated USB-C power-delivery rating with the laptop’s charging requirement, then check which peripheral ports you need. | I would like fewer desk connections, but I need to know whether one cable can provide the video, peripherals and charging I expect. |
| Two-computer use | Check inputs for both computers. If one keyboard and mouse must serve both, confirm explicit KVM support and the USB connections specified for that model. | At a shared desk, I want to switch computers without repeatedly moving my keyboard and mouse cables. |
USB-C identifies the connector, not every function behind it. HP’s USB-C dock specifications require host support for DisplayPort Alt Mode for the relevant dock functionality; Microsoft Support also notes that external-display connections depend on the device model and cable or adaptor.
Check the exact laptop model’s video-output standard, supported display settings and the cable needed before choosing a USB-C monitor or dock.
A different adaptor, dock or cable may be needed if the planned connection is not supported.
A second screen and a raised laptop solve different layout problems. The Health and Safety Executive identifies both a separate display and a raised-laptop arrangement with separate input devices for prolonged laptop use.
Map out the screen, keyboard and mouse positions first. Choose a monitor if you need a separate display; consider a stand with separate input devices if keeping the laptop screen meets your needs.
USB-C monitors have model-specific power-delivery ratings: BenQ lists 65W for the GW2790QT, while Dell lists up to 90W for the P2425E. Neither figure establishes what a particular laptop requires.
Compare the monitor or dock rating with the laptop manufacturer’s charging requirements, including any conditions attached to that rating.
If the available power does not meet the laptop’s requirements, you may still need to use its own charger.
Video inputs let a monitor receive signals from different computers, but do not establish that it can switch a shared keyboard and mouse. BenQ describes KVM support and its required connections as model-dependent.
For a shared desk, check both the video inputs and explicit KVM instructions for the monitor you are considering.
Without suitable switching, sharing peripherals may require a separate KVM device or reconnecting them.
These model examples illustrate features to compare; a brand name alone does not establish the ports or adjustments on another model.
Dell’s UK P2425E specification is an example to examine when desk space and USB-C hub functions both matter.
The UK GW2790QT specification gives a concrete QHD USB-C option for a fixed desk.
LG’s UK 27U730A-B specification is a reference for comparing a 27-inch 4K IPS display with USB-C laptop charging.
These monitor options are for the separate-screen route at a home laptop desk. A laptop stand and a compatible dock or adaptor remain different choices, depending on whether you need to raise the existing screen or connect additional equipment.

Consider this separate screen for a fixed desk where a WQHD IPS display fits the work you do. Check the laptop’s supported video output and intended display settings, and confirm charging requirements separately if you plan to use a USB-C connection.

This is a separate QHD IPS screen to consider for regular desk work or study. Match its intended connection and display setting to the laptop, and confirm the supplied configuration if USB hub connections are part of your desk plan.

If you want a separate screen connected over USB-C, check that the laptop supports video through the port and that its charging needs suit the planned setup. Confirm the monitor’s actual weight and mounting requirements if you expect to move or mount it.

This larger curved screen calls for a check of available desk space before it becomes part of a regular work setup. Its name specifies 3840×2160 resolution, a 165Hz refresh rate, Type-C 65W and a USB hub; confirm the laptop’s supported display mode, Type-C video output and charging requirement rather than assuming it can use every stated feature.

Consider the 31.5-inch screen if a larger separate display fits your desk; the product name also specifies built-in speakers. Check the laptop’s video connection and the screen-positioning options before choosing cables or a mounting arrangement.
No. The Health and Safety Executive says that, where DSE requirements apply, the employer should assess the individual home workstation, check whether the worker’s own equipment is suitable and decide on additional equipment through that assessment. A raised laptop with separate input devices may meet a different need from a separate monitor.
The Health and Safety Executive says UK DSE requirements can apply to permanent, long-term and hybrid home workers. It identifies DSE users as workers who use display screen equipment daily as part of normal work for continuous periods of an hour or more; where the requirements apply, the employer must assess the workstation, including home use.
No. A USB-C connector alone does not establish video-output capability. HP specifies host support for DisplayPort Alt Mode for the relevant USB-C dock functionality, while Microsoft Support says external-display compatibility depends on the device model and the cables or adaptors used. Check your laptop’s exact specifications before buying.
Compare the monitor’s stated USB-C power delivery with the laptop manufacturer’s charging requirement, then confirm that the planned connection also supports the intended display setting. BenQ lists 65W for its GW2790QT and Dell lists up to 90W for its P2425E; those model-specific figures do not establish what your laptop needs.
A stand can be the appropriate choice when the laptop screen provides enough space and the main need is to raise it; it does not add a second display. For prolonged laptop use, the Health and Safety Executive advises using a separate keyboard and mouse with a raised laptop and also identifies a separate display as an option.
