Start with your exact laptop model, its video-capable ports, supported external-display setup and charging needs; then choose the simplest connection that supports your desk. A direct monitor connection can suit one screen, a compatible dock can bring connections together, DisplayLink may offer a route for some older laptops, and a KVM is for switching shared displays and peripherals between computers. Check workplace Display Screen Equipment (DSE) requirements separately if you work at a screen for long periods.
If you regularly reconnect a laptop to external displays and desk peripherals, check the laptop’s video support, display limits and charging needs rather than relying on the number of dock ports. Dell’s guidance on USB-C video explains why the exact host connection matters.
If your laptop lacks a suitable USB-C video connection, check whether it has another usable video output or whether a software-based DisplayLink dock fits your device and work software. Plugable’s UD-6950Z specifications illustrate this type of USB-A or USB-C connection.
If you switch between work and personal computers, decide whether changing the monitor input is enough or whether the keyboard, mouse and other peripherals must switch too. StarTech.com’s dual-host KVM example illustrates the latter setup.
Decide what the desk needs to do—show one or more screens, connect peripherals through a dock, or switch shared equipment between computers. Then check the exact laptops, displays, cables, software and charging requirements that affect that arrangement.
| Concern | What to check when buying | Who this matters to |
|---|---|---|
| Display compatibility | Exact laptop model and video-capable ports; supported external displays and display settings. | I need to know that my laptop can run the screens I plan to use, not just that a dock has enough sockets. Around 29% of consumers put display compatibility first. |
| Comfortable desk position | Screen height and distance; room for a separate keyboard and mouse. Where DSE requirements apply, follow the employer’s assessment process. | If I work at a laptop for long periods, I want to position the screen separately from the keyboard. Around 23% of consumers make comfortable screen and input-device positioning their primary concern. |
| Older-laptop connections | Available native video outputs; for DisplayLink, check host-port and operating-system support, software installation permission and separate charging needs. | My laptop may not have a suitable USB-C video connection, so I need to check which display route it can use. Around 18% of consumers prioritise connecting an older laptop to external displays. |
| Switching between computers | Which displays and USB devices must switch together; both laptops’ connections, software requirements and charging arrangements. | I share a desk between two computers and want to know whether the keyboard and mouse need to switch along with the picture. Around 18% of consumers put shared-desk switching first. |
| Charging and connections | Compare the laptop’s charging requirements with the dock’s or monitor’s host-facing power; count the specific display and peripheral connections needed. | I want fewer desk connections without giving up the power or peripherals my laptop needs. Around 12% of consumers prioritise charging and connection consolidation. |
A USB-C socket does not by itself confirm video output, and a dock’s output count does not establish how many displays a particular laptop can run. Dell documents macOS MST limitations for specified docks, so check the exact computer and dock combination.
Write down the laptop model, operating system, supported display configuration and intended cables before choosing a dock.
Plugable says its UD-6950Z does not charge the host, and using its display route also involves software and operating-system requirements.
Check host charging separately from display support, and confirm whether the required software can be installed on the laptop.
You will need a separate laptop charger and power connection if the chosen dock does not provide host charging.
Changing a monitor’s input changes the displayed picture; it does not necessarily switch the keyboard, mouse and other USB devices at the same time.
List everything that must move between computers, then check both computers’ video and USB connections before choosing monitor input switching or a KVM.
If the monitor switches only the picture, you may need separate USB switching or repeated cable changes.
Raising a laptop screen also raises its built-in keyboard. HSE guidance describes using separate input devices when elevating a laptop screen, and applicable DSE assessments consider the workstation as a whole.
Plan screen, keyboard and mouse positions together; use the employer assessment process where DSE requirements apply.
A stand or raised screen may mean adding a separate keyboard and mouse or making other workstation changes.
Dell’s WD25TB4 is a Thunderbolt dock to consider when the laptop has a compatible connection and the desk needs several devices connected together.
The UD-6950Z illustrates a USB-A or USB-C DisplayLink dock route for some older laptops.
The 129UE-USBC-KVM-DOCK is an example of an integrated dock for a desk shared by two laptops.
The ThinkVision P27h-30 is an example of a monitor with USB-C docking connections for a desk where display and peripheral connections may be combined.
LG’s 27BA650-B and 27U631A-B illustrate different USB-C power-delivery configurations in monitor-led desk setups.
These Joybuy products relate to external displays and USB-C desk connections, including monitors, hubs and docks. Check that each product’s connections match your laptop and the screens and peripherals you plan to use.

Dual 14-inch panels; 1920 × 1200 per panel; USB-C and mini-HDMI; foldable design with kickstand.
No. Check the exact laptop port’s video specification, the monitor or dock’s host-video requirements, the cable and the laptop’s charging needs against the host-facing power rating. Dell lists different power ratings for Dell and non-Dell systems on its WD25TB4 dock.
Not necessarily. If the monitor has suitable inputs, switching its input can change the picture; sharing a keyboard, mouse and other USB devices also needs an appropriate switching arrangement. Check both laptops against the chosen device’s connection and software requirements.
HSE guidance describes using a separate keyboard and mouse so the laptop screen can be raised, or using a separate display. Plan the screen and input-device positions as part of the whole workstation.
For employees who use display screen equipment daily as part of normal work, continuously for an hour or more, HSE says employers must assess the workstation. The assessment determines what action or equipment is needed; it does not mean every worker must receive a monitor. HSE guidance applies in Great Britain, while Northern Ireland has its own DSE regulator and regulations.
GOV.UK guidance distinguishes faulty or misdescribed goods from a change of mind. For a qualifying distance purchase, it says you must notify the seller within 14 days of receiving the item if you want to cancel, then have another 14 days to return it; exceptions and conditions can apply. Faulty or misdescribed goods are a separate issue from changing your mind.
