For regular laptop work, choose the display and its position around the tasks you do and the space on your desk, then check what your laptop can connect to. An external monitor with a separate keyboard and mouse can let you position the screen independently; choose a USB-C hub monitor only if the laptop supports the intended video connection and its charging requirement matches the monitor’s stated output. Add a dock or arm to solve a specific connection or positioning need, rather than assuming either is necessary.
The useful starting point is the part of your laptop workstation that needs to change: screen position, connections or space for your work.
If you work at a desk for sustained periods, consider whether you can position the screen without leaving the keyboard and trackpad awkward to use. The Health and Safety Executive’s laptop guidance describes using a separate display, keyboard and mouse to allow independent screen placement.
If you reconnect a laptop each time you work at home, a hub monitor or dock may simplify your desk connections. Check the exact laptop’s video output, supported display arrangement and charging requirement before planning around one cable.
If you regularly keep files or wide sheets open side by side, compare the screen area you need with the width and depth available on your desk. A wider display still has to connect to your laptop and sit at a usable height.
Decide where the screen and input devices will sit, confirm the laptop’s display limits, then choose any extra connections or screen area your work calls for.
| Priority | What to check | Your needs |
|---|---|---|
| Screen position | Check the stand’s height and other adjustments against your desk and seated position. If using an arm, check the monitor’s mounting pattern, weight and available fixing space. Plan where a separate keyboard and mouse will go. | I use my laptop for sustained work and need to place the screen independently of the keys and trackpad. The Health and Safety Executive advises separate input devices and a separate screen for prolonged laptop use. |
| Video compatibility | Match a documented laptop video output to the monitor input and cable or adapter. For USB-C, confirm video support; check the exact laptop’s supported display count, resolution and refresh rate for your planned arrangement. | A USB-C socket alone would not tell me whether my laptop can run the display I want. The Video Electronics Standards Association describes DisplayPort over USB-C as an Alternate Mode connection; Apple Support says Mac display limits depend on the model and connected displays. |
| Charging and ports | Compare the monitor or dock’s stated USB-C Power Delivery with the laptop’s charging requirement. Check whether you need its USB ports or Ethernet connection, as well as video output. | I would like fewer desk connections, but only if one cable handles the video, charging and peripherals my laptop and work require. |
| Screen area | Compare the screen size and resolution with your usual windows. Measure desk width and depth, including space for the stand, and confirm that the laptop supports the intended resolution. | I often work across documents or wide spreadsheets, so horizontal space matters to me. LG describes its 34BA75QE-B’s 21:9 screen as suitable for side-by-side files, but that use case does not establish a productivity gain for everyone. |
| Workstation arrangements | If an employer display screen equipment assessment applies, confirm its findings and the employer’s equipment process before paying personally. | I want to know what my workstation assessment calls for before choosing equipment. In Great Britain, the Health and Safety Executive says that, where the regulations apply and an assessment indicates the employer needs to provide DSE equipment, the worker cannot be charged for it. Northern Ireland has separate guidance from the Health and Safety Executive for Northern Ireland. |
A USB-C connection does not, by itself, establish video output, a particular display limit or sufficient laptop charging.
Check the laptop model’s video specifications, supported display arrangement and charging requirement alongside the monitor or dock and the intended cable. Apple Support notes that supported external displays on a Mac depend on the model and the displays’ resolution and refresh rate.
In Great Britain, the Health and Safety Executive says an individual assessment is required where the DSE regulations apply, and workers cannot be charged when that assessment indicates the employer needs to provide equipment.
Confirm the assessment findings and your employer’s provision or reimbursement arrangements before paying personally. For work in Northern Ireland, consult the employer’s arrangements and guidance from the Health and Safety Executive for Northern Ireland rather than treating Great Britain guidance as a UK-wide rule.
Moving the laptop screen higher also moves its keyboard and trackpad. The Health and Safety Executive’s laptop guidance calls for a separate keyboard and mouse so the screen can be elevated.
Plan space and connections for separate input devices when using a riser or positioning the laptop screen beside another display.
Extra horizontal screen area is useful only if the display and its stand fit where you work and can be positioned appropriately.
Measure desk width and depth, check the stand footprint and adjustment, and confirm the laptop can drive the intended display resolution.
These specific models illustrate different screen and connection choices; their features should not be assumed to apply to other monitors from the same brands.
Dell UK lists the Pro 27 Plus QHD USB-C Hub Monitor P2725DE as a 27-inch, 2560 × 1440 display with 90W USB-C Power Delivery, RJ45 Ethernet and up to 150 mm of height adjustment.
BenQ UK describes the GW2790QT as a 27-inch QHD USB-C monitor with an integrated hub, 65W laptop power delivery and height, tilt, pivot and swivel adjustment.
LG UK lists the 34BA75QE-B as a 34-inch, 21:9 WQHD curved display with 90W USB-C Power Delivery, RJ45 Ethernet and height, tilt and swivel adjustment.
These options cover three parts of a laptop workstation: a separate display, an adapter for monitor and desk connections, and separate input devices. Choose the part that addresses your setup rather than treating the accessories as substitutes for a monitor.

Consider this separate Full HD display when you need another screen for laptop work. Check the required laptop video connection and how you will position the screen at your desk.
No image available
Consider this adapter if an existing monitor setup needs its listed 4K HDMI or VGA connection, Gigabit Ethernet or dual USB 3.0 ports. Its name states 100W Power Delivery; check the laptop’s video capability and charging requirement rather than assuming the adapter changes either limit.

Separate keyboard and mouse input can help when your laptop screen is raised or you use an external monitor. Check the keyboard layout and connection compatibility for your laptop; this set does not add display space.
Check the exact model’s video outputs, supported number of external displays, and the resolution and refresh rate available in your intended arrangement. Match those details to the monitor input and cable or adapter; Apple Support notes that external-display limits vary by Mac model and display arrangement.
No. Video over USB-C requires the relevant display capability, such as DisplayPort Alternate Mode, while USB Power Delivery is a separate power capability. Confirm both in the laptop’s documentation, then compare the monitor or dock’s stated charging output with the laptop’s requirement.
Plan for separate input devices if you need to raise the laptop screen or position a separate display for prolonged laptop work. The Health and Safety Executive’s laptop guidance pairs a separate display with a separate keyboard and mouse so screen and input positions can be set independently.
Yes, if an employer DSE assessment may apply, confirm its findings and equipment arrangements before paying personally. For Great Britain, the Health and Safety Executive says workers cannot be charged when an assessment under the applicable regulations indicates that the employer needs to provide DSE equipment; Northern Ireland has separately administered guidance.
Neither size is preferable for every laptop desk. Consider an ultrawide when side-by-side documents are a recurring need and your desk has room for it; a 27-inch QHD screen is another option when that wider format is unnecessary. For either choice, check adjustment, desk fit and the laptop’s supported display resolution.
