Choose the connection before the screen: a one-cable USB-C setup makes sense only if your laptop can send video through that port and the display provides enough power for it. For a permanent desk, choose between one screen and two according to the windows you need visible and the space available; choose a portable screen when the display needs to travel, after checking its host-port and power requirements.
Who needs which setup?
How often the screen moves, and how many windows must stay visible, are useful starting points for choosing a home-working display.
Laptop users returning to the same desk
A USB-C display or compatible dock can reduce the connections made each time the laptop is set down. Check the exact laptop port for video output and compare its charging requirement with the display or dock’s stated power output.
Document-heavy workers with a permanent desk
One larger, higher-resolution screen may suit documents and spreadsheets; two screens are worth considering when a meeting or reference window needs to remain visible beside the main task. Desk space and supported display outputs still determine what is practical.
Hybrid workers carrying a second screen
A portable display is easier to move between work locations than a fixed desk monitor, but provides a smaller physical workspace. Check its specific video and power requirements against the laptop before relying on one-cable use.
What should you check before choosing?
Decide whether one fixed screen, two screens or a portable display fits the work pattern; then check the computer connections and physical setup before settling on a model.
One fixed screen
Choose it when: You want more room for documents and calls without arranging two external displays.
Trade-off: A single screen cannot keep as many separate full-size windows visible as a two-screen arrangement.
Two screens
Choose them when: A meeting, reference document or message window needs to stay visible beside the main application.
Trade-off: The arrangement needs more desk space and compatible outputs; a dock’s supported display configuration depends on the host computer.
Portable screen
Choose it when: The second display needs to move between work locations.
Trade-off: It offers less physical screen area than a fixed desk display and may require specific USB-C video and power support.

What to check |
Your needs |
| Video connection |
Match the computer’s output to the display input. For USB-C video, check the exact host port: VESA explains that DisplayPort over USB-C uses Alternate Mode. For two screens, confirm the supported display count and intended resolution with the laptop or dock maker. |
I want the screen to work with my computer’s actual ports, whether that means USB-C video or a separate HDMI or DisplayPort connection. |
| Laptop charging |
Compare the laptop maker’s charger requirement with the monitor or dock’s stated power delivery, including any host-specific conditions. Dell UK lists up to 90W for the P2425HE and lists 100W for Dell systems versus 96W for non-Dell systems on the WD25 dock. |
A single cable would make reconnecting easier, but I need to know whether the display or dock can provide enough power for my laptop. |
| Screen workspace |
Consider resolution, screen size, aspect ratio and how many windows must remain visible. Lenovo UK lists the fixed ThinkVision P27h-30 at 2560 × 1440; measure the usable desk area before planning a larger screen or a pair. |
Documents and meetings need room on screen, but the display arrangement also has to fit my desk. |
| Positioning |
Check the stand’s stated height, tilt, swivel or pivot adjustments against the available desk space. The Health and Safety Executive identifies daily display-screen use for continuous periods of an hour or more as a display-screen-equipment context. |
I need to place the screen sensibly within my whole workstation, rather than choosing by panel size alone. |
Common setup mistakes
-
Assuming every USB-C socket carries video
USB-C describes the connector, not every capability behind it. VESA describes DisplayPort over USB-C as an Alternate Mode; Lenovo UK specifies DP1.2 Alt Mode and PD2.0 support for one-plug use of its ThinkVision M14.
Check the manual for your exact laptop and port before choosing a display that depends on USB-C video.
-
Assuming a display can replace any laptop charger
Power output varies by device and can depend on the host. Dell UK states up to 90W for its P2425HE monitor; its WD25 dock lists different outputs for Dell and non-Dell systems.
Compare the laptop maker’s power requirement with the relevant monitor or dock specification, and check compatibility guidance for that laptop.
-
Buying a second monitor before planning the desk
Two displays take more physical space and require enough compatible video outputs. A dock’s multiple-display modes do not establish which arrangement a particular laptop can run.
Measure the usable desk width and confirm the host or dock supports both intended screens at the resolutions you plan to use.
-
Choosing by panel size without considering placement
A screen still needs a workable position within the whole home workstation; panel size alone does not tell you whether its stand will suit your desk.
Check the stand adjustments and assess the complete workstation. If you use display-screen equipment regularly for work, follow your employer’s assessment process where applicable.
Relevant brand references
These examples illustrate connection and format differences in specific product lines; brand inclusion does not establish availability or compatibility with your computer.
Dell
Dell UK’s P2425HE monitor and WD25 dock provide examples of a fixed USB-C display and a separate docking route.
- Dell UK lists up to 90W power delivery for the P2425HE and 100W for Dell systems or 96W for non-Dell systems on the WD25.
- Those output figures do not establish that either device meets a particular laptop’s video or charging requirements.
Lenovo ThinkVision
Lenovo UK lists both the fixed QHD P27h-30 and portable ThinkVision displays, serving different desk and travel needs.
- The P27h-30 specification lists a 2560 × 1440 panel, USB-C Gen 2, DisplayPort-out, Ethernet and a USB hub.
- For one-plug use of the separate ThinkVision M14 model, Lenovo specifies a notebook USB-C port supporting DP1.2 Alt Mode and PD2.0; a USB-C socket alone is not a compatibility check.
BenQ
BenQ UK presents the GW2790 as a fixed 27-inch Full HD, 100Hz home monitor and describes its own eye-care features.
- Its stated size and resolution give buyers a defined fixed-screen format to compare with their desk and workspace needs.
- The GW2790’s Full HD format may not fit a requirement for QHD workspace; check the exact inputs and laptop connection before choosing it for a one-cable desk.

Frequently asked questions
Is a USB-C socket enough to connect a monitor with one cable?
No: the laptop’s specific port must support the video mode the monitor requires. VESA describes DisplayPort over USB-C as using Alternate Mode, and Lenovo UK specifies DP1.2 Alt Mode and PD2.0 for one-plug use of its ThinkVision M14. Check the manual for your exact laptop port and display.
How can I tell whether a monitor will charge my laptop?
Compare the monitor or dock’s stated power-delivery output with your laptop maker’s charging requirement and compatibility guidance. Dell UK lists up to 90W for the P2425HE; its WD25 dock lists 100W for Dell systems and 96W for non-Dell systems. Neither figure confirms suitability for every laptop.
Can a portable monitor work from one USB-C cable?
It can when the laptop port supplies the video and power modes required by that monitor. For example, Lenovo UK specifies DP1.2 Alt Mode and PD2.0 support for one-plug use of the ThinkVision M14. Check the exact portable model and laptop port rather than relying on the connector shape.
What should I check about a monitor supplied in Great Britain?
Check the safety and conformity information for the exact model being supplied. The Office for Product Safety & Standards states that the Electrical Equipment (Safety) Regulations 2016 set requirements before electrical equipment is placed on the Great Britain market. Great Britain guidance should not automatically be applied to Northern Ireland, where provisions differ.
