Check your laptop’s external-display limit and video-capable ports before choosing a screen: Apple Support notes that a hub does not raise a Mac model’s maximum supported display count. A directly connected desktop monitor suits a regular desk, while a portable monitor suits changing locations if its video and power requirements match the laptop. Choose a dock when you also need to reconnect charging and desk peripherals through one cable; check mounting compatibility separately if you want an arm.
If you regularly work from one home desk, a desktop monitor gives documents and communication tools more room. Decide whether a direct connection is enough or whether a dock would also simplify your other desk connections; check the laptop’s supported display configuration either way.
If your workspace changes between locations, consider a portable monitor’s weight, stand and connection requirements. Lenovo UK, for example, specifies DisplayPort Alt Mode and Power Delivery support on the laptop’s USB-C port for its ThinkVision M14 one-plug setup; do not assume the same connection works with every laptop or monitor.
If displays, charging and USB accessories all need reconnecting, a dock can bring those connections together. Match its display modes, host connection, operating-system support and power output to the exact laptop before choosing one.
Start with what the laptop can drive, then choose the screen and connection that fit where you work.
| Priority | What to check | Your needs |
|---|---|---|
| Display support | Find the exact laptop model’s external-display limit. Check the intended screen count, resolution and refresh rate together; Apple Support says these affect supported configurations on Macs. | I want another screen for documents and calls without choosing a display arrangement my laptop cannot run. |
| Video connection | Match a video-capable laptop output to the monitor input. For native DisplayPort video over USB-C, check for DisplayPort Alt Mode; the Video Electronics Standards Association describes this as a specific USB-C capability, not a property of the connector’s shape. | A single direct cable may cover my extra-screen need; an adapter matters if the supported laptop output and monitor input differ. |
| Dock and charging | For a dock, check the host port, operating system, display modes and peripheral ports. Compare its stated Power Delivery output with the laptop’s charging requirement, including any adapter or cable requirements. | I would rather reconnect displays, charging and desk accessories through one cable than plug them in separately. |
| Where you work | Compare a fixed monitor’s desk footprint with a portable display’s weight, stand and power needs. Check each model’s connection requirements rather than assuming all portable screens work through one USB-C cable. | If I move between workspaces, I need a second screen I can take with me; at a regular desk, I can accommodate a fixed display. |
| Mounting | Match the monitor’s VESA hole pattern and weight to the arm’s supported range. Check the desk attachment, thickness and clearance for movement and cables; Ergotron identifies hole pattern and weight as primary mount-compatibility criteria. | I want to adjust the screen or free up desk space, but the arm must fit both my monitor and desk. |
A USB-C connector does not, by its shape alone, establish that the laptop can send video to a monitor. The Video Electronics Standards Association describes DisplayPort Alt Mode as a capability for carrying DisplayPort video over USB-C.
Check the exact laptop port specification against the monitor, adapter or dock’s required video connection.
A dock adds connection points, but Apple Support says a supported hub or daisy-chain does not increase a Mac model’s maximum number of external displays.
Check the laptop’s supported display count and configuration before matching it to a dock’s outputs and operating-system requirements.
Power Delivery output varies by product and connection. A stated output is useful only if the laptop and the complete connection can use it.
Compare the product’s stated output with the laptop’s charging requirement, and check the required power adapter and cable.
An arm also needs to match the monitor’s mounting holes and weight. Desk attachment and clearance determine whether it can be installed and moved as intended.
Compare the exact monitor and arm specifications, then measure the desk attachment area and space behind the screen.
Dell’s UK P2425HE is an example of a fixed-desk monitor with USB-C hub functionality.
Lenovo’s ThinkVision M14 illustrates the portable secondary-screen route.
Kensington offers docking options for connecting displays and desk peripherals through a laptop dock.
Ergotron’s mounting guidance is relevant when screen placement, rather than video connectivity, is the desk problem.
These options cover fixed and portable monitors, a dock and a display adapter for laptop-based work. Choose the connection route only after checking your laptop and intended screen arrangement.

A fixed-desk monitor option when you want more room for documents and applications; the product name specifies an IPS QHD display.
Check the exact laptop video connection and display limit. If you plan to charge through the monitor or use its hub, confirm the required output, connections and included cables for this variant.

A portable FHD monitor option for a secondary screen that moves between workspaces.
Check that your laptop supports the monitor’s required USB-C video mode and power connection, as well as another external display.
No image available
A fixed-desk monitor option with an IPS WQHD display, as specified in its product name.
Confirm the laptop’s video compatibility and intended display configuration. If monitor charging or an arm matters, check this variant’s Power Delivery output and mounting specifications before relying on either.

A dock option when two HDMI display connections and a single reconnection point suit your desk workflow. Its product name specifies 4K and 100W Power Delivery pass-through; those figures do not establish what your laptop can drive or receive.
Check the laptop’s display limit, host connection and charging requirement, and confirm the dock’s required external power adapter and what the package includes.
No image available
An adapter option when the laptop’s supported USB-C video output needs an HDMI or VGA connection. The product name also specifies Gigabit Ethernet, 100W Power Delivery pass-through and dual USB 3.0 ports.
This adapter’s stated video setup is for a single display, not multiple independent external displays. Check USB-C DisplayPort Alt Mode support and the laptop’s charging needs.
Check the exact laptop model’s supported external-display count, resolution and refresh-rate combinations, then identify which ports output video. A USB-C connector alone does not confirm DisplayPort Alt Mode, USB4 or Thunderbolt capability; use the laptop manufacturer’s port specification to match the screen or adapter.
Do not assume so: a dock provides outputs, but the laptop must support the intended display configuration. Apple Support explicitly says a supported hub or daisy-chain does not raise a Mac model’s maximum external-display count. Check both the exact laptop and dock before planning multiple screens.
A direct cable or suitable adapter is an option when you need one extra monitor and the laptop already supports its video connection. Consider a dock instead if displays, charging and other desk peripherals need to reconnect together, subject to the laptop’s host-port and display limits.
No. Compare the monitor’s stated Power Delivery output with the laptop’s charging requirement and check the host port and cable. The USB Implementers Forum describes a range of possible USB Power Delivery levels; a particular monitor and laptop must support the power used in their connection.
Match the monitor’s VESA hole pattern and weight to the arm’s supported pattern and weight range. Ergotron identifies those as primary compatibility criteria; also check the desk attachment, clearance behind the screen and room for cable movement.
