Start with the applications and documents you need visible, then check whether your laptop can drive the display arrangement you want. One external monitor is a simpler starting point; add a second only if your laptop, connections and desk can support it. A laptop stand with a separate keyboard and mouse is another option when an external screen will not suit your workspace.
If you want a document, reference material or communication window visible without continually rearranging your laptop screen, decide whether one external display alongside the laptop is enough or whether you need two screens.
If you regularly reconnect a laptop at home or share a desk with another laptop user, check video compatibility, charging needs and the peripherals you want to connect rather than assuming one cable will cover everything.
If your desk has limited usable space, compare a positionable external screen with raising the laptop and using a separate keyboard and mouse. The arrangement needs to leave room for your viewing position and input devices.
Decide how many screens you need for your work first; then check laptop display support and desk space before choosing a monitor, adapter or dock.
| Concern | What to check when buying | Who this matters to |
|---|---|---|
| Room for simultaneous work | Decide which windows must stay visible; compare screen count, resolution and available inputs. | If I need documents and communication visible together, I will weigh one external screen against the extra space and connections of a second; about 29% of consumers put simultaneous work first. |
| Laptop compatibility | Check the exact laptop model, video-capable ports and supported number of external displays. | If I am buying for a laptop I already own, I need the proposed screen count and connection route to work with its limits; about 23% of consumers prioritise compatibility. |
| Desk fit and screen position | Measure usable width and depth, and check the stand base, adjustment range and any mount requirements. | If my desk is compact, I need a screen position that leaves room for my viewing distance and input devices; about 18% of consumers put desk fit first. |
| Reconnecting a laptop | Check USB-C video support, the laptop’s charging requirement, power delivery and the ports or software your setup needs. | If I move my laptop on and off the desk, I want to avoid repeatedly reconnecting separate devices where a compatible setup can combine them; about 18% of consumers prioritise quick reconnection. |
| Keeping the setup simple | Check which cables and input devices you need, and whether a basic connection meets your requirements before adding a dock. | If I mainly want a more comfortable screen position without extra display area, I would rather avoid components I do not need; about 12% of consumers put simplicity and expense first. |
The USB-C connector shape alone does not confirm video support or enough charging power for your laptop.
Check the exact laptop port specification, the monitor’s video and power features, and your laptop’s charging requirement before choosing a hub monitor.
Depending on the equipment, you may need a separate adapter or charger as well.
The laptop’s display limit and the dock’s video method both affect the result. DisplayLink is a software-based approach, with drivers and, on macOS, permissions to consider.
Check the exact laptop model, operating system, complete connection path and any workplace rules on installing software.
A screen still needs to fit the desk at a workable viewing distance, with room for your keyboard, mouse and laptop.
Measure usable desk width and depth, then check the monitor’s base and adjustment range. The Health and Safety Executive advises positioning the screen top around eye level and the screen about an arm’s length away.
A stand, mount or different screen arrangement may be needed if the monitor base crowds the desk.
For example, BenQ specifies the GW2790 as Full HD and the distinct GW2790QT as QHD with USB-C power and DP-out MST; similar names do not establish matching specifications.
Compare the full model identifier and the manufacturer’s specifications before choosing a listing.
The P2725D and U2723QE illustrate different 27-inch monitor configurations.
The GW2790 and GW2790QT show different options in BenQ’s 27-inch monitor range.
The 27UP850K-W is an example of a 27-inch 4K monitor with USB-C display, data and charging functions.
The ThinkVision T24i-30 is a 23.8-inch Full HD example with HDMI and DisplayPort inputs.
The DK30C2DPEPUE is an example of a USB-C and USB-A dock for connecting displays and peripherals.
These options cover a single 27-inch external monitor and portable laptop screen extenders, including dual-screen arrangements. Check your laptop’s display support and connections, and consider whether a fixed desk or mobile workspace better suits the format.

A laptop-attached option if you want two additional screens rather than a single external display.
The product name specifies two FHD 1080p screens at 60Hz, USB-C connectivity and compatibility with 14–16-inch laptops.
No image available
A portable single-screen option if you want an external display that can be used with a laptop.
The product name lists USB-C and HDMI connections, a smart-cover stand and VESA mounting.
No. Check the exact laptop port’s video capability, the monitor’s USB-C video and power specifications, and your laptop’s charging requirement. DisplayPort Alt Mode is one method of sending video over USB-C. BenQ specifies 65 W for the GW2790QT; that figure does not apply to every USB-C monitor.
No; the laptop’s display limit and the dock’s video method both matter. Apple Support UK specifies one native external display for the M1 MacBook Air, while its instructions for using two displays with M3 MacBook Air models include model-specific conditions, including closing the lid. DisplayLink is a separate driver-dependent route, so check whether you can install the software and meet its requirements.
In Windows, open Settings, then System and Display to identify and arrange connected screens. Microsoft Support explains how to detect displays; match the on-screen layout to where the monitors sit on your desk and check the connections if a display is not detected.
Not automatically. Health and Safety Executive guidance says that where a display-screen equipment assessment indicates equipment is needed, workers cannot be charged for it. Whether equipment is needed depends on the assessment of the relevant workstation and circumstances.
For an eligible UK distance purchase, GOV.UK guidance says you can notify the seller of cancellation within 14 days of receiving the item and then have another 14 days to return it. Check the applicable exceptions and the seller’s return procedure. Faulty or misdescribed goods are subject to separate rights.
