Choose a separate screen if you regularly need documents, meetings or reference material visible side by side and can position the display comfortably. A portable monitor may suit a workspace that changes location; if that need is occasional, keeping a laptop-only setup may be simpler. Before buying a monitor or dock, check your laptop’s video output, supported display count, cable requirements and charging needs.
If you regularly compare documents or keep a meeting visible while writing, a second display gives those windows separate places on your desk. Check that the screen and your input devices can be positioned comfortably.
A USB-C monitor may carry video and, on compatible equipment, provide laptop charging or access to peripherals. The laptop port, cable and monitor must support the functions you intend to use; a matching connector shape is not enough.
If you cannot leave a conventional monitor on the desk, a transportable display or a different mounting arrangement may be worth considering. Check where it will stand, how it will receive power and how often you will need to move it.
Start with how often you need two visible work areas, then check the space and connection your preferred setup requires. A desk monitor can remain in place, a portable display needs a workable support and power arrangement, and a dock or adapter cannot override the laptop’s display limits.
| Concern | What to check | Who this matters to |
|---|---|---|
| Side-by-side workspace | Identify the windows you need open together, then check display size and usable desk space. | If I compare documents while keeping a meeting or reference material in view, persistent screen space matters more than an occasional extra window. Around 27% of consumers put this need first. |
| Connection and cables | Check the exact laptop’s video output and supported display count against the monitor input; verify the cable, adapter and charging requirements separately. | I want to connect the screen without discovering that my USB-C port cannot provide the video or charging arrangement I planned. For around 33% of consumers, connection compatibility is the primary concern. |
| Space and movement | Measure the usable desk area and check whether the stand, kickstand or mount has secure support and a practical power arrangement. | When my workspace is shared or I move between rooms, I need a screen I can position without crowding the desk. This comes first for around 20% of consumers. |
| Whether to add a screen | Consider how often you need simultaneous windows and whether your current workstation meets your needs. | If I rarely need two windows visible at once, extra equipment may complicate a setup that already works for me. Around 20% of consumers primarily want to avoid an unnecessary addition. |
A USB-C socket alone does not establish that the laptop can send a display signal through the intended cable, adapter or dock. Apple Support advises checking a Mac’s video ports and supported display count; Microsoft Support notes that USB-C functionality can vary with the hardware and software combination.
Check the exact laptop model, its video-output standard and the monitor’s input before choosing the cable or adapter.
A compatible replacement cable, adapter or dock may be needed if the existing connection cannot perform the required function.
A monitor that leaves too little room for the laptop, keyboard or mouse may be difficult to position comfortably. Which? identifies size and ergonomic adjustment as monitor-buying considerations.
Measure the usable desk width and depth, including space for input devices, and check the supplied stand’s adjustments or a suitable mounting option.
A different stand or mounting arrangement may be necessary where the supplied stand crowds the working area.
USB-C power-delivery ratings differ between monitors. For example, LG lists 90 W for its 27U730A-B and Lenovo lists 75 W for its L27h-4A; neither rating establishes what a particular laptop needs.
Compare the monitor’s stated output with the laptop manufacturer’s charging requirements, and check whether the intended cable supports the complete setup.
You may still need to use the laptop’s own charger.
Another display can help with a task without resolving poor screen placement or a cramped workstation. The Health and Safety Executive advises assessing the individual home workstation for workers to whom its display screen equipment guidance applies.
If you work at home long-term or split your working time between home and another workplace, use your employer’s workstation assessment process where applicable. For study or occasional use, begin with the task and the space you actually have.
These examples illustrate different display and connection arrangements; the specifications belong to the named models, not to every monitor from each brand.
The Dell S2725DC is an example of a fixed-desk, 27-inch QHD USB-C monitor.
The LG 27U730A-B illustrates a 27-inch 4K desk-monitor arrangement with USB-C.
The Lenovo L27h-4A illustrates a desk monitor with connections for a laptop and USB peripherals.
The ASUS ZenScreen MB27ACF illustrates a transportable-screen approach rather than a conventional permanent desk setup.
These monitors cover fixed-desk screens and one transportable option for adding a display to a laptop workspace. Choose the connection and placement arrangement your laptop and working area can support.

Consider this fixed-desk monitor if you regularly need a separate area for documents or reference material.
The product name identifies an IPS WQHD display. If you intend to connect or charge a laptop through USB-C, confirm its video capability and charging requirements against the connection you plan to use.

This is another desk-monitor option for keeping work visible beside a laptop display.
The product name identifies an IPS WUXGA display. If USB peripherals or laptop charging are part of your plan, confirm the functions of this particular configuration and your laptop before buying.

Consider this model where a fixed 27-inch second screen fits the desk and the listed smart-monitor features are relevant to your use.
Its product name specifies a 4K UHD IPS display and USB-C 65 W. Check the laptop’s video-output and charging requirements before relying on a USB-C connection.

Consider this transportable model if your second screen must move or use a different placement arrangement from a conventional desk stand.
The product name identifies an IPS USB-C model. If carrying weight, a clamp or partition mounting, or USB-C charging matters to you, confirm those details for this configuration and your laptop before purchase.

This fixed-desk monitor is worth considering for document work if a 24-inch screen fits alongside your laptop and input devices.
Check the laptop’s video output against the monitor’s actual inputs before choosing a cable. Confirm the model’s ports if you specifically intend to connect through USB-C.
No: the port must support the video connection required by the monitor. Check the exact laptop model and cable; Apple Support also advises checking a Mac’s supported external-display count, while Microsoft Support notes that USB-C functionality can be limited by the hardware and software combination.
Yes, if the laptop, monitor and cable support both functions and the monitor’s power output meets the laptop’s needs. LG lists simultaneous display, data and 90 W charging for its 27U730A-B, but that model-specific specification does not establish compatibility with every laptop.
Not necessarily: a direct connection may work when the laptop’s video output matches the monitor input. Consider an adapter for differing connectors or a dock if you need additional peripheral connections, but check the laptop’s display limits and the complete port-and-cable combination first.
No: the right setup depends on the work and the individual workstation. The Health and Safety Executive advises workstation assessment for applicable permanent, long-term or hybrid home workers using display screen equipment; a second screen should address a particular need rather than substitute for appropriate positioning and setup.
