If your laptop and monitor have matching HDMI ports and you need one extra screen, a direct cable avoids a dock’s additional compatibility checks. Consider a USB-C monitor for display and charging, an adapter for a different monitor input, or a dock for several desk connections—but first confirm the laptop’s video output, the required charging power and the connections each device provides.
A separate display can provide room for documents and applications alongside the laptop. For regular desk work, consider where both screens and the keyboard will sit; the Health and Safety Executive also advises home workers to arrange screens, desk space and lighting to manage reflections and glare.
Reading course material while writing or joining an online class may call for more visible workspace. If the desk is limited, check the monitor’s dimensions and stand footprint rather than choosing by screen diagonal alone.
A USB-C socket does not, by itself, tell you whether the laptop can send video to a monitor. Check the exact laptop model’s display-output specification before choosing a USB-C monitor, video adapter or dock.
Start with the display connection the laptop can actually use, then decide whether the desk also needs charging or peripheral connections.
Choose when: The laptop has HDMI output, the monitor has HDMI input and one additional screen is enough.
Bear in mind: The display cable does not add laptop charging or desk-peripheral connections.
Choose when: The laptop supports video over its USB-C port and you want the monitor to handle display and, if specified, charging.
Bear in mind: The monitor’s power-delivery rating must meet the laptop’s charging requirement; USB-C does not establish either capability on its own.
Choose when: The laptop has documented USB-C video output but the chosen monitor needs a different input, such as HDMI or DisplayPort.
Bear in mind: An adapter cannot add video output to a data-only laptop port.
Choose when: The desk also needs several peripherals, Ethernet, charging or more than one external display.
Bear in mind: Display layouts, host compatibility and charging limits depend on the exact dock and laptop.
| Priority | What to check | Your needs |
|---|---|---|
| Screen and desk fit | Measure the usable desk area and monitor footprint. Compare screen dimensions and resolution for the documents you use. | I want room for course material, calls or documents without crowding the laptop and keyboard. Which? distinguishes smaller screens for limited spaces from larger monitors suited to home offices. |
| Video connection | Match the laptop output to the monitor input. For USB-C, confirm a documented video mode on the exact laptop; check the supported external-display mode too. | A cable or adapter needs to work with my laptop’s actual port, not just have a connector that fits. Which? notes that USB-C carries DisplayPort video only where the connection supports it. |
| Charging | Compare the laptop’s stated charging requirement with the monitor or dock’s power-delivery rating. Check whether that rating changes with the connected laptop. | If I want fewer cables on the desk, the display or dock must supply suitable power. Dell UK, for example, specifies different delivery figures for Dell and non-Dell systems on its Pro Dock WD25Z. |
| Desk connections | List the USB devices, Ethernet connection and external displays you intend to use. Check the dock’s host compatibility and stated display-output arrangement. | For one extra screen, I may only need a direct cable; a dock matters if I also connect several devices at the desk. |
| Screen positioning | Check height, tilt, swivel or pivot adjustment where needed. Consider the stand footprint, lighting and likely reflections. | I need to position the screen within my desk layout rather than rely on diagonal size alone. The Health and Safety Executive highlights screen adjustment and lighting when arranging a workstation. |
USB-C describes the connector, not a guaranteed display-output mode. A data-only laptop port will not become a video output because an adapter or monitor is attached.
Look up the exact laptop model’s documented USB-C video capability before selecting a USB-C display cable, adapter or dock.
Power delivery varies by product and can depend on the connected system. Dell UK lists 130W for Dell systems and 96W for non-Dell systems on its Pro Dock WD25Z.
Compare the applicable host power figure with the laptop maker’s charging requirement.
If the available power does not meet that requirement, you may need to keep using the laptop’s original charger.
A monitor also needs to fit alongside the laptop and leave room to position the screen and manage reflections.
Measure the desk, then check the monitor’s dimensions, stand footprint and relevant adjustment options.
A dock introduces its own laptop-compatibility, charging and display-layout checks. A matching direct video connection may cover a single-screen setup without those additional functions.
Count the displays and peripherals you will connect before deciding whether the dock’s other ports serve a desk-use need.
These brand ranges illustrate features to compare; the ports, adjustment and charging figures belong to particular models, not every product carrying the brand.
Dell UK lists conventional monitors, USB-C monitor options and laptop docks for desk setups.
Lenovo’s ThinkVision docking-monitor and dock ranges address setups that combine a display with other desk connections.
HP’s UK USB-C monitor range includes office displays with different combinations of display and hub connections.
Samsung’s UK business-monitor range includes USB-C or Thunderbolt and adjustable-screen categories.
LG’s Ergo monitor designs are relevant when screen placement matters on a home desk.
These options include external monitors for adding screen space and a dock for connecting displays and desk peripherals. Choose the connection route only after checking your laptop’s outputs and, where relevant, charging needs.

An external display option for work or study at a laptop desk. Check the laptop’s video output against the connection you plan to use; if you intend to charge through the monitor, compare the laptop’s requirement with the applicable power-delivery specification. Confirm which display cable is supplied for this variant.
No image available
A USB-C display option when the laptop has documented video output through the port you intend to use. Check that output, the charging requirement if you want power through the display, and how the screen will fit on your desk. Confirm whether the power adapter is included for this variant.
No image available
A QHD external-display option for a laptop desk. If you plan to use USB-C for video or charging, confirm the exact laptop’s display-output capability and charging requirement against this model’s specifications. Check which cable is supplied for this variant.

The 22-inch screen is an option to measure against a smaller desk area. Before choosing a direct display cable, confirm the laptop’s output, the monitor input you intend to use and the laptop’s supported external-display mode. Do not plan on charging the laptop through this monitor without confirming that function.
No image available
A dock route to consider when a desk setup calls for HDMI display connections alongside other devices. Confirm the exact laptop’s USB-C video mode, operating-system and display compatibility, and charging requirement. This dock requires an external adapter rated at 100W or higher; check whether one is included.
No: the laptop’s USB-C connection must support video output. Which? notes that DisplayPort video support depends on the connection, so check the exact laptop model for DisplayPort Alt Mode, Thunderbolt or another explicitly documented display-output mode before buying.
It can if the chosen product supplies power delivery suitable for that laptop. Compare the laptop maker’s charging requirement with the product’s applicable host-power figure; Dell UK, for example, specifies 130W for Dell systems and 96W for non-Dell systems on its Pro Dock WD25Z.
Not necessarily. If the laptop output and monitor input match and one extra screen is all you need, a direct cable covers that connection; consider a dock when you also need supported peripheral, Ethernet, charging or additional display connections.
Check its physical fit and connection to the laptop first, then consider the screen adjustment your desk arrangement needs. Which? distinguishes smaller screens for limited spaces from larger home-office displays, while the Health and Safety Executive advises arranging screens and lighting to manage reflections and glare.
