For a laptop that usually stays at one home desk, start with an adjustable external monitor; choose a portable display when the second screen needs to travel. A dock or monitor arm can solve a separate connection or positioning problem, but neither replaces a check of your laptop’s video output, charging requirements and available desk space.
If documents, browser windows and calls share the same home desk, an external screen gives you another way to arrange that workspace. Check its stand and laptop connection alongside screen size. The Health and Safety Executive’s display-screen guidance also addresses people who routinely split their work between home and a workplace.
At a compact desk or multi-use table, consider where the screen and keyboard will sit when work starts—and what must move afterwards. Which? distinguishes smaller displays for limited spaces from larger monitors suited to home offices.
If the extra screen must travel, a portable monitor is worth considering instead of a permanent desk display. Check how it connects and stands up at each location: ASUS says USB-A hybrid-signal use on its ZenScreen MB16ACE requires a DisplayLink driver.
Decide where the screen will be used most often, then check its position and the complete connection from laptop to display—not just the shape of the socket.
| Priority | What to check | Your needs |
|---|---|---|
| Screen position | Check height and tilt adjustment, desk depth and room for a separate keyboard and mouse. The Health and Safety Executive advises positioning the screen around arm’s length away, with its top approximately at eye level. | I work at the same desk regularly and want to place the screen and input devices without hunching over my laptop. |
| Laptop connection | For USB-C video, confirm the laptop’s supported display output, such as DisplayPort Alt Mode. If the monitor or dock will charge it, compare the stated USB Power Delivery output with the laptop’s charging requirement. VESA and the USB Implementers Forum describe video and power delivery as capabilities to check, not guarantees of every USB-C socket. | One desk cable would be useful, but I need to know that it will provide the video and charging functions my laptop requires. |
| Desk space and ports | Measure the space for the screen and stand, then list the display inputs and peripheral ports you will use. If the monitor cannot provide those connections, check a compatible adapter or dock separately. | I want space for documents and calls without letting the display or its cables take over a compact work surface. |
| Moving the screen | Check the portable monitor’s dimensions, weight, stand and required connection method. For USB-A hybrid-signal use, check whether its driver can be installed on your work laptop; ASUS specifies a driver requirement for that connection on the ZenScreen MB16ACE. | My second screen needs to move between locations, so packing it and setting it up matter more to me than a permanent desk stand. |
A USB-C connector alone does not establish that the laptop can send display video or that the monitor or dock supplies enough power to charge it.
Check the laptop’s display-output specification and charging requirement against the monitor or dock. Confirm the cable and any adapter needed for the intended connection.
A separate charger, compatible cable or adapter may be needed if the planned connection cannot provide every function.
A display can fit the desk yet still be difficult to position alongside the keyboard and mouse. The Health and Safety Executive advises a workable screen position for prolonged laptop use.
Measure the desk and check the stand’s height and tilt range. If you plan to use an arm, confirm the monitor mount and the arm’s desk and weight limits.
Changing the screen position may also call for a separate keyboard and mouse, riser or compatible arm.
A portable display’s temporary stand may offer a different range of positioning from an adjustable desktop stand. Its connection method may also require a driver.
For regular work at one desk, compare screen positioning with a fixed monitor before choosing portability. For work across locations, check the portable model’s stand and connection at each planned setup.
Dell P2425H and P2425HE have different complete model identifiers. Do not assume a specification for one—including its hub or charging functions—applies to the other.
Match the full model number before comparing ports, charging output and stand features on a product listing.
These model examples illustrate different setup questions; the stated features should not be assumed for every monitor from the same brand.
Dell’s P2425HE is a fixed-desk USB-C hub monitor to consider when a compatible laptop needs display and desk connections.
LG’s 27BA650 is a 27-inch fixed-desk option for someone with room for a larger display and an adjustable stand.
ASUS’s ZenScreen MB16ACE illustrates the portable-display route for a screen that moves between work locations.
BenQ’s GW2490T is a compact fixed-desk reference when screen adjustment matters.
These monitors cover fixed-desk and movable second-screen setups. Choose the workspace first, then check the connection and positioning details of the particular model.

A fixed-desk option for laptop work where screen positioning and connections matter. Check your laptop’s USB-C video support and charging requirement before planning a one-cable setup.
No image available
Consider this fixed-desk monitor if a larger workspace suits your desk and viewing distance. Before relying on USB-C for laptop charging, confirm its stated power output against your laptop’s requirement.

This movable-screen option is worth considering where the display needs flexible positioning between workspaces. If you will carry it regularly, confirm its actual weight: the product description gives two different figures. Check laptop video support and charging needs for the intended USB-C connection.

This fixed-desk model is aimed at a workspace with room for a 27-inch screen. Its listed Mac-focused features are not a compatibility guarantee for another laptop; confirm the required USB-C video and charging functions for your device.
No image available
A portable second-screen option when the display needs to travel. Confirm that your laptop supports the required USB-C video connection, and check how you will position the screen for prolonged work at a fixed desk.
No: the connector shape alone does not establish video output or adequate charging. Check the laptop for compatible display output, such as DisplayPort Alt Mode, and compare the monitor or dock’s USB Power Delivery output with the laptop’s charging requirement. VESA and the USB Implementers Forum describe these as distinct connection capabilities.
The Health and Safety Executive advises putting the screen approximately an arm’s length away, with its top around eye level and the screen and keyboard in front of you. For prolonged laptop use, a separate keyboard and mouse allow the laptop screen to be raised; a separate display is another option.
Discuss the equipment needed for your work with your employer. Acas advises employers and staff to agree who will provide or pay for equipment and repairs, as well as what technical support is needed; that discussion can establish the practical arrangement for a monitor or dock.
No. Check the monitor’s mounting specification and the arm’s supported weight and size, then confirm desk thickness and clamp clearance. VESA’s mounting-interface standard does not establish that every particular monitor, arm and desk combination fits.
