Start with the laptop: confirm its video-capable ports, supported number of external displays, intended resolution and refresh rate, and charging needs. A direct connection can suit a one-monitor desk; a compatible dock can bring displays and peripherals onto one host connection, while a KVM is for sharing a screen and input devices between two laptops. DisplayLink-capable docks offer a driver-based route where native display support is unsuitable, but software requirements and the exact host remain part of the decision.
If you want two or more external screens, establish what your exact laptop can drive before choosing a dock. Apple Support notes that supported external-display counts depend on the Mac model; Kensington also lists host-specific display limits for its SD5760T dock.
If you move a laptop between home and work, a dock may reduce the connections needed for a monitor, everyday peripherals and charging. Check the host connection and power specifications: StarTech.com lists a hybrid USB-A/USB-C dock that does not charge the laptop.
If work and personal laptops use the same monitor, keyboard and mouse, a KVM may reduce cable swapping. Check both laptops and the number of screens you need: ATEN describes its US3310 as a single-monitor switch, while StarTech.com offers a dual-monitor KVM dock.
Choose it when: One external screen meets your needs and the laptop has a compatible video output.
Trade-off: A direct display cable does not also consolidate your other peripherals and charging.
Choose it when: Your laptop supports the intended displays and you want one host connection at a regular desk.
Trade-off: The dock’s video outputs cannot override the host’s display limits; charging and video modes also depend on the host and connection.
Choose it when: A compatible driver-based dock fits a laptop whose native display connections do not meet your plan.
Trade-off: DisplayLink requires suitable software and host resources; DisplayLink Support says performance depends on available processing power.
Choose it when: Two compatible laptops need to share a monitor, keyboard and mouse.
Trade-off: Both hosts must suit the switch, and models differ in monitor count, video mode and charging.
| Concern | What to check | Who this matters to |
|---|---|---|
| Display compatibility | Check the exact laptop’s video-capable ports and supported external-display count against your planned resolution and refresh rate. Apple Support says display limits depend on the Mac model. | I want two independent screens, so I need to know my laptop can drive both before choosing a dock. Around 33% of consumers put display compatibility first. |
| Desk connections and charging | Match the dock’s host connection and stated Power Delivery output to the laptop; check which peripherals it connects. StarTech.com notes that its hybrid USB-A/USB-C dock does not provide laptop Power Delivery. | When I return to my desk, I want to reconnect my screen, peripherals and laptop power with less cable handling. For around 27% of consumers, that consolidation is the main concern. |
| Sustained desk use | Consider screen placement, desk space, stand stability and separate input devices as parts of the workstation. The Health and Safety Executive advises considering the whole workstation where display screen equipment assessment applies. | I spend long periods at this desk, so screen and input-device positions matter alongside the connection itself. Around 20% of consumers make the workstation arrangement their primary concern. |
| Switching laptops | Check each host’s video connection, the switch’s monitor count and its supported video mode. ATEN’s US3310 shares one monitor; StarTech.com also lists a dual-monitor KVM dock. | I use work and personal laptops at the same desk and want them to share my keyboard, mouse and screen without reconnecting each device. Switching is the first priority for around 20% of consumers. |
The connector alone does not establish video support. Microsoft Support notes that USB-C-compatible cables do not all support the same features.
Check the exact laptop’s video-output specification and use a cable suited to the connection and functions you need.
A different cable or adapter may be needed if the chosen connection cannot carry video.
Two sockets on a dock do not mean every laptop can run two independent external screens. Apple Support says the supported number depends on the Mac model, and Kensington lists a one-external-display condition for certain hosts using its SD5760T.
Compare the exact laptop model’s display limit with the dock’s host-specific specifications and your planned resolution and refresh rate.
Charging varies by dock and power arrangement. StarTech.com states that one of its hybrid USB-A/USB-C docks does not provide laptop Power Delivery.
Check the stated charging output, the laptop’s requirements and whether the necessary power adapter is included.
You may need to keep using the laptop’s own charger or provide a compatible adapter.
A screen alone does not settle its position or the arrangement of your other equipment. The Health and Safety Executive advises assessing the whole workstation where display screen equipment rules apply, including relevant home and office arrangements.
Before choosing screen size or a stand, consider desk space, monitor placement, keyboard and mouse position, lighting and the rest of the workstation.
Kensington’s docking range includes USB-C, USB4 and Thunderbolt options for a fixed desk.
StarTech.com lists native USB-C docks, USB-A/USB-C DisplayLink docks and dual-host KVM docks.
ATEN’s US3310 is a KVM dock switch for sharing one HDMI monitor and USB peripherals between compatible USB-C devices.
These monitors, USB-C docks and adapters cover direct-display and peripheral-connection options. Match any chosen item to your laptop’s outputs and display limits; a two-laptop KVM is a separate route.

Consider this as a separate screen at a regular laptop desk. The product name specifies a 31.5-inch 2K IPS display and built-in speakers; check the laptop’s video output and the cable needed for your intended connection.

This is a separate 24-inch FHD screen for a laptop desk. Confirm that your laptop has a suitable video output and that the intended cable matches the monitor connection.
No image available
Consider this for a desk that needs two HDMI connections and laptop charging through a dock. Its stated 100W Power Delivery pass-through requires an external 100W or higher adapter; check whether a suitable adapter is included and whether your exact laptop supports two independent displays at the intended modes.
No image available
Consider this adapter when one external display, wired networking and USB connections meet your desk needs. Its product name lists HDMI, VGA, Gigabit Ethernet, dual USB 3.0 ports and 100W Power Delivery; the specified SST video operation is for a single display, not multiple independent screens. Check the laptop’s USB-C video and charging compatibility.
No image available
Consider this hub for an external display alongside USB devices and memory cards. Its product name specifies HDMI 4K at 60Hz, USB-C and USB-A data connections, SD/TF card slots and 3.5mm audio. Check that the laptop supports the required USB-C video mode; if charging through the hub matters, confirm laptop Power Delivery support separately.
Check your exact laptop model’s supported external-display count before matching the dock, monitors and cables to your intended resolution and refresh rate. Two video sockets do not establish that a particular laptop can run two independent screens; Apple Support says a hub or daisy chain does not increase a Mac model’s maximum supported display count.
No: a USB-C connection needs video-output support to drive a monitor. Check the laptop and cable specifications rather than relying on the connector shape; Microsoft Support notes that not all USB-C-compatible cables support every feature.
It may be possible with a compatible DisplayLink-capable dock, which uses software rather than native video output through USB-A. Confirm operating-system and driver support, the dock’s stated display modes and the laptop’s available resources; also check charging separately, as StarTech.com says its hybrid USB-A/USB-C DisplayLink dock does not provide laptop Power Delivery.
The Health and Safety Executive’s guidance does not prescribe that shopping list for every home worker. It says display screen equipment rules can apply to permanent, long-term and hybrid home workers who use it daily for continuous periods of an hour or more; where the rules apply, employers should assess the individual workstation, including home and office arrangements where relevant.
