For one compatible external monitor, start with a direct video cable; consider a USB-C hub monitor if you want the screen and suitable laptop charging through one connection, or a dock if your desk also needs multiple displays or several peripherals. Check your exact laptop model’s video-capable ports, external-display limits and charging requirement before choosing: a USB-C socket alone does not establish what the setup can do.
If you use one laptop at a fixed desk and want fewer separate connections, a USB-C monitor or dock may combine display, charging and peripherals. The laptop must support the required video connection, and the available charging power must suit it.
If you connect two displays or regularly use wired networking and several peripherals, a dock may simplify connecting your laptop at the desk. Check the laptop’s supported display configuration as well as the dock’s ports.
For sustained home-office or study work, screen position and the space taken by a stand can matter as much as screen size. The Health and Safety Executive advises achieving a comfortable, sustainable posture for applicable home display-screen work.
Choose it when: One screen is enough and the laptop has a compatible video output.
Bear in mind: Charging and desk peripherals remain separate unless the monitor offers those connections.
Choose it when: You want a fixed-desk screen that can also handle compatible USB-C video and suitable laptop charging.
Bear in mind: Charging power varies by model and may not meet your laptop’s requirement.
Choose it when: One laptop connection needs to serve multiple displays or several fixed desk peripherals.
Bear in mind: A dock cannot exceed the laptop’s own supported display outputs.
| Concern | What to check | Who this matters to |
|---|---|---|
| Video and charging compatibility | Check the exact laptop’s video-capable ports and display support. If charging through a monitor or dock, compare its Power Delivery rating with the laptop’s requirement. | I need the screen to connect to my existing laptop, and I do not want to rely on one-cable charging unless it meets my needs. Around 42% of consumers put this compatibility concern first. |
| Displays and peripherals | Count the required screens and desk connections, then compare the laptop’s display limit with the dock’s supported configurations. | With more than one screen or several devices on my desk, I want to reconnect the laptop without handling each cable separately; around 33% of consumers prioritise expansion. |
| Screen position and desk fit | Measure usable desk space and check stand adjustment or, for an arm, mounting and clamp suitability. | I need to position a second screen comfortably without crowding my desk. Desk fit and positioning come first for around 25% of consumers. |
A USB-C socket does not, by itself, establish that it can send a picture to a monitor. Which? notes that DisplayPort support depends on the connection, while Lenovo specifies a compatible USB-C video mode or Thunderbolt for its relevant docks.
Look up the exact laptop model and the capabilities of the port you intend to use before choosing a cable, adapter or dock.
Lenovo says actual dock video output depends on the connected system. A dock’s stated display modes therefore do not establish how many screens your laptop can drive at the resolution and refresh rate you want.
Check the laptop manufacturer’s supported external-display configuration against the dock’s host requirements.
Charging ratings differ between models: BenQ lists 60W for the BL2785TC, LG lists up to 60W for the 32UN880K-B, and Dell lists 90W for the U2424HE. None of those ratings establishes what your laptop requires.
Compare the specific monitor’s Power Delivery rating with the laptop manufacturer’s charging guidance before planning to put its usual charger away.
A screen that fits across the desk may still leave too little depth or too little adjustment for a comfortable position. An arm also needs a suitable mount and desk attachment.
Measure the desk and check the monitor’s stand adjustments or the arm’s mounting and clamp requirements before buying.
Relevant when comparing a USB-C hub monitor with a separate dock for a fixed desk.
Relevant when a compact dock or a dual-display desk connection is under consideration.
Relevant when comparing adjustable USB-C monitors for a one-cable desk.
Relevant when screen position and the desk footprint of a larger monitor are priorities.
These monitors offer different ways to add a laptop screen, while the dock is for a desk that needs additional display and device connections. Choose the connection route against your laptop’s capabilities before comparing individual models.

Consider this adjustable external screen for a fixed laptop desk, particularly if you are planning a USB-C connection.
The product name specifies a Nano Glossy IPS panel, HDR P3 and a height-adjustable stand. Check the exact laptop’s video compatibility, charging requirement and available desk space before relying on a one-cable arrangement.
No image available
This external monitor is an option when you want a separate screen for desk work or creative tasks.
Its product name identifies an IPS WQHD model. Confirm the video connection your laptop can provide; if you intend to charge through the monitor, check its Power Delivery rating against the laptop’s requirement.

Consider this dock if a fixed laptop desk needs two HDMI display connections rather than just one monitor cable.
The product name specifies dual HDMI 4K and 100W Power Delivery pass-through in retail packaging. Check the laptop’s supported external displays and USB-C video capability, whether its charging needs are met, and whether the external adapter required for your setup is included.

This larger external monitor may suit a fixed desk if its curved screen and physical size fit the space.
The product name specifies 3840 × 2160 resolution, 165Hz, 0.03ms GTG, HDR400, DCI-P3 99%, Type-C 65W and a USB hub. Check the laptop’s video connection separately: the Type-C power rating alone does not establish that the port carries video or supplies enough power for your laptop.

Consider this additional laptop screen if you need a display that can move between work locations rather than stay on a fixed desk.
Its product name identifies the MB166CR FHD variant. Check that the laptop has a compatible USB-C video output before choosing it for your setup.
Check the specification for the exact laptop model and port for USB-C video support, such as DisplayPort Alt Mode or Thunderbolt. Which? explains that DisplayPort capability depends on the USB-C connection, so the shape of the socket is not enough to confirm it.
A dock is worth considering when you need to reconnect multiple displays or desk peripherals alongside the laptop, rather than connect only one screen. Check the laptop’s external-display limit first: Lenovo states that actual video output through its docks depends on the connected system.
It can be a charging connection if its Power Delivery rating meets the needs of your laptop and workload. BenQ specifies 60W for the BL2785TC, LG specifies up to 60W for the 32UN880K-B, and Dell specifies 90W for the U2424HE; compare the rating of the model you choose with your laptop manufacturer’s guidance.
Check that the monitor can be positioned comfortably on your available desk, including its stand adjustments or any arm mounting. For applicable employees working at home permanently, long term or routinely as part of a home-and-workplace pattern, the Health and Safety Executive advises employers to assess display-screen workstation risks and help workers achieve a comfortable, sustainable posture; that guidance is not a requirement for every private purchase.
