For one extra work screen, start with a direct monitor connection if your laptop has a compatible video output. A USB-C or Thunderbolt dock or hub monitor makes more sense when you also need to reconnect peripherals regularly, but video and charging depend on the laptop; a DisplayLink dock is a separate, software-dependent option for some USB-A or mixed-device setups. On a small desk, check where the screen, stand, keyboard and mouse will fit before choosing a larger display.
If you need space for documents and calls rather than a full desk hub, check your laptop’s video output and choose a monitor with a matching input. In Windows, display settings let you arrange an external screen after connecting it, as Microsoft Support explains.
A USB-C or Thunderbolt dock or hub monitor is worth considering when you regularly connect a screen, keyboard, mouse and other peripherals. Confirm the laptop’s video and charging capabilities before relying on a single cable.
A hybrid DisplayLink dock may provide a route for a laptop without suitable native display connections. Check the operating system, required software, display configuration and separate laptop power arrangement first.
Start with the exact laptop model and the number of screens you need; then check how the finished workspace will fit on your desk.
Choose when: You need one extra screen and the laptop has a compatible video output.
Trade-off: A direct connection does not gather your other desk peripherals into one connection.
Choose when: You reconnect a laptop and several peripherals at the same desk and its video and charging capabilities match the equipment.
Trade-off: The dock or monitor’s ports and power rating cannot override the laptop’s own display or charging limits.
Choose when: A USB-A laptop or mixed set of laptops needs a compatible software-based display route.
Trade-off: DisplayLink requires operating-system and driver checks, and laptop charging needs a separate check.
| Priority | What to check | Your needs |
|---|---|---|
| Display compatibility | Check the exact laptop’s video outputs, supported external-display count, resolution and refresh rate. Dell Support explains that DisplayPort video over USB-C requires that capability on the host port. | I want the planned screen layout to work with my laptop, not merely to find a cable that fits its socket. |
| Desk fit and positioning | Measure usable width and depth, including the stand and keyboard space. The Health and Safety Executive advises placing the screen directly in front, about an arm’s length away, with its top around eye level. | There needs to be room to position the screen without crowding my keyboard and mouse. |
| Peripherals and power | Match the dock’s display and peripheral connections to your equipment; compare its stated power delivery with the laptop’s charging requirements. For Kensington’s SD4781P, a USB-A host needs an alternative power source, according to Kensington. | I reconnect several desk devices and would like fewer cables to handle, but still need a workable charging arrangement. |
| DisplayLink requirements | Check the intended dock’s operating-system support, drivers, host USB connection and display mode. DisplayLink Support says software performance depends on processing power and the operating system. | My laptop may need a USB-A-compatible display route, so I need to know whether the software-based setup will work on it. |
USB-C describes the connector, not every function the laptop provides through it. Dell Support’s DisplayPort-over-USB-C guidance concerns ports that support that video capability; an adapter cannot create native video output on an unsupported port.
Check the exact laptop specification and port markings before choosing a USB-C display cable, hub monitor or dock.
Charging depends on the dock and host connection. Kensington says USB-A hosts need another power source with its SD4781P; StarTech.com says its DK30A2DH does not provide USB-C Power Delivery to charge a laptop.
Check whether charging works through the host connection you intend to use and whether the stated output meets the laptop’s requirements.
You may still need to connect the laptop’s own charger or arrange another suitable power source.
A stand that takes too much desk space can make positioning difficult. The Health and Safety Executive advises a screen about an arm’s length away, with its top around eye level; Which? also considers smaller screens relevant to limited spaces.
Measure desk depth and stand footprint, then check the adjustment range or intended VESA mounting arrangement.
DisplayLink uses software. DisplayLink Support notes that performance depends on the computer and operating system, and its Windows compatibility guidance includes graphics and USB driver checks.
Confirm the dock’s supported system, drivers, intended screen configuration and laptop power arrangement before buying.
These examples illustrate different connection arrangements; their specifications apply to the named models, not every product from the brand.
Dell’s P2426E is an example of a USB-C hub monitor for a one-screen laptop desk.
Kensington’s SD4781P is a hybrid USB-C and USB-A docking example for desks using different laptop connections.
StarTech.com’s DK30A2DH is another USB-C and USB-A dock example for a DisplayLink-based setup.
These options include external monitors for adding a laptop screen and a USB-C dock for connecting displays and desk peripherals. Check each option against your laptop’s connections and intended desk layout.

A QHD monitor to consider for an additional work screen. If you plan to use USB-C for video or charging, check the laptop’s DisplayPort Alt Mode support and charging requirements against this model before relying on that connection.
No image available
Consider this USB-C monitor if flexible screen placement matters. Confirm laptop video and charging compatibility, the included mounting accessories and power adapter; also confirm its weight if you expect to move it regularly.
No image available
A separate work screen with Full HD (1920 × 1080) resolution and listed HDMI, DisplayPort and VGA connections. Match the intended input to your laptop’s output; do not rely on the listed USB-C port for video or charging without confirming its functions.
No image available
A docking option when you want to connect two HDMI displays and desk peripherals. Check the laptop’s USB-C video support and intended dual-display mode, then confirm the required external power adapter, package contents and charging arrangement.
No image available
Consider this additional screen for a workspace that moves between locations. Confirm that the laptop supports USB-C DisplayPort Alt Mode and check the included support arrangement so you can position the screen where you will use it.
Check the official specifications for the exact laptop model for DisplayPort over USB-C, DisplayPort Alt Mode, Thunderbolt or another documented video-output capability. Dell Support notes that a DisplayPort marking can help identify a supported port, but the laptop documentation should confirm its function.
No: a conventional video adapter needs a compatible video source and cannot create native video output from an unsupported USB-C port. If the laptop needs another route, check a DisplayLink dock’s operating-system, driver, display and power requirements for that specific laptop.
Some DisplayLink-based hybrid docks can, under their stated display and software conditions. Kensington lists two external 4K displays at 60 Hz for its SD4781P, while noting that a USB-A host needs an alternative power source. Check the exact dock and laptop combination rather than assuming two sockets guarantee your intended layout.
Choose a screen and stand that fit the usable desk depth and leave room for your keyboard and mouse, rather than selecting by diagonal size alone. The Health and Safety Executive advises positioning the screen directly in front, about an arm’s length away, with its top around eye level; check stand adjustment or a suitable VESA mount against your measurements.
You can use both if the laptop supports the display arrangement and you can position the screens comfortably. For prolonged laptop work, the Health and Safety Executive advises a separate keyboard and mouse so the laptop screen can be raised; Microsoft Support explains how to arrange connected displays in Windows.
