A fixed home monitor and dock are worth considering if you regularly use the same desk and need to reconnect several peripherals. A portable second screen makes more sense when display space must travel with you; if video calls are the main issue, start with the relevant call accessory instead. Before buying, check your exact laptop’s display and charging capabilities and whether your employer permits the equipment.
If you repeatedly reconnect a display, input devices and other peripherals at one home desk, a fixed setup may simplify that routine. Confirm that your laptop supports the intended connections and ask your employer about its equipment process; Acas advises employers to agree what home-working equipment and support are needed.
If extra display space matters at both home and work, consider the screen’s size, carrying weight and video connection together. For a concrete example, ASUS lists its ZenScreen MB166C at 0.78 kg without a stand and specifies USB-C DisplayPort Alt Mode input.
Check permission before choosing a personal dock, webcam or other peripheral. The National Cyber Security Centre notes that organisations can restrict external interfaces, while Microsoft documents controls on device installation and driver privileges on managed Windows computers.
Decide first whether the accessory needs to stay on your home desk or travel with your laptop. Then check the connections and employer rules that determine whether the setup will work.
Consider it when: One home desk regularly needs a display and several peripherals reconnected.
Trade-off: The equipment stays at the desk, and its display and charging capabilities still depend on the laptop, cable and employer policy.
Consider it when: You need extra screen space at more than one location.
Trade-off: You must carry and set it up, and its video input must match the laptop’s output.
Consider them when: Your laptop screen is sufficient but your video-call setup needs a different camera or audio device.
Trade-off: They do not add screen space or consolidate desk connections.
| Priority | What to check | Your needs |
|---|---|---|
| Desk reconnection | Count the display and peripheral connections you use at home. Check whether the proposed monitor or dock can carry the required video, data and charging functions with your laptop and cable. | I regularly move my laptop between work and a home desk and want fewer connections to remake each time. |
| Display and power compatibility | Check the exact laptop model’s external-display limits, including resolution and refresh rate. Compare its port capabilities and charging requirement with the monitor or dock specifications; Apple notes that supported external displays vary by Mac model and display settings. | A second screen or dock needs to work at the display settings I plan to use, without assuming that a USB-C connector also provides suitable charging. |
| Employer approval | Ask IT whether personal USB, Thunderbolt or wireless peripherals are permitted and whether installation requires approval. The National Cyber Security Centre and Microsoft describe organisational controls that can restrict interfaces, devices or drivers. | I use a managed laptop, so I need to know which accessories I can actually connect and use. |
| Screen and input arrangement | Consider how often you work at each location and what screen and separate-input arrangement you need. Where display screen equipment rules apply, the Health and Safety Executive says assessment should cover both home and office use. | My setup should be workable in both places; I do not want to assume a full fixed desk is the right answer before considering my routine. |
| Video calls | Check the camera’s connection and stated operating-system requirements, then confirm employer permission. Compare those needs with what your current laptop setup already provides. | If calls are the main difficulty, I would rather address the camera or audio setup than add a screen I do not need. |
The connector shape alone does not establish how many displays the laptop can run or whether a particular monitor or dock can charge it. Apple specifies that external-display support varies by Mac model and by display resolution and refresh rate; LG and Dell publish charging limits for their individual products.
Check the exact laptop, monitor or dock, and cable specifications against the display and charging arrangement you intend to use.
An employer-managed laptop may restrict peripheral access or installation. The National Cyber Security Centre describes controls on external interfaces, and Microsoft documents device-installation and driver-permission controls for managed Windows devices.
Ask IT about personal accessories, required drivers and any approved-device process before buying.
Dell specifies up to 130W power delivery for Dell systems and 96W for non-Dell systems on the WD25TB4. Its stated display configurations are also conditional; the dock’s maximum is not a promise that a particular laptop can use that configuration.
Match the dock’s host requirements to your laptop’s charging requirement and published external-display limits.
For workers to whom display screen equipment rules apply, the Health and Safety Executive says assessment should address home and office use. If that assessment indicates the employer must provide equipment, the worker cannot be charged for it.
Use your employer’s workstation assessment and equipment process before deciding what to buy personally.
These model-specific examples illustrate different connection and display choices; a brand’s presence here does not mean every product in its range suits your laptop.
The Dell Pro Thunderbolt 4 Dock WD25TB4 is a reference point for a fixed desk with multiple connections.
The LG 27U730A-B illustrates a fixed home monitor with a USB-C charging connection.
The ZenScreen MB166C is a portable-display example for a second screen that moves between locations.
The Brio 4K is a webcam reference for a call-focused setup rather than added screen space.
DisplayLink is a docking technology to distinguish from a laptop’s native display connection when assessing a dock.
These options cover portable second screens, adapters for a desk display and peripherals, and a call-focused webcam. Choose by the job the accessory needs to do, then confirm laptop compatibility and work-device permission.

For carrying a second screen between locations. ASUS specifies a 1920 × 1080 IPS panel, 0.78 kg weight without a stand and USB-C DisplayPort Alt Mode input. Check that your laptop provides that video output; this model has no HDMI input or built-in speakers.
No image available
Another portable second-screen option, with a touchscreen and a 180° adjustable stand named in the product listing. Check its video and power connections against your laptop, and confirm the carrying weight if you plan to take it to work regularly.
No image available
For connecting a desk display and wired peripherals through an adapter. Its product name specifies 4K HDMI, VGA, Gigabit Ethernet, dual USB 3.0 ports and 100W Power Delivery. Confirm the laptop’s video output and charging requirements before relying on those connections.
No image available
A call-focused option when another display is not the priority. Its product name specifies a four-microphone array, speakers, fixed focus and a 98° adjustable field of view. Check the required USB connection, operating-system compatibility and employer permission.
No image available
For a desk needing a display connection and several peripheral ports. Its product name specifies HDMI up to 4K at 60 Hz, USB-C and USB-A data ports, SD/TF slots and 3.5 mm audio. Check the host laptop’s video support and confirm laptop-charging capability separately.
Do not assume you must buy equipment before using your employer’s assessment process. The Health and Safety Executive says that where display screen equipment rules apply, assessment should cover relevant home and office use; if an assessment indicates the employer must provide equipment, the worker cannot be charged for it. The equipment needed depends on the individual assessment.
No: the connector alone does not establish either capability. Check your exact laptop’s supported display count, resolution, refresh rate and charging input, then compare them with the dock and cable requirements. Apple, for example, says external-display capacity varies by Mac model and display settings; DisplayLink notes that USB-A/B docks are not designed to charge laptops.
Ask your employer’s IT team before buying one. The National Cyber Security Centre describes organisational controls that can restrict peripheral access, and Microsoft documents device-installation and driver-permission controls on managed Windows computers. The answer depends on your employer’s policy and the particular accessory.
Choose a portable screen if you need extra display space at more than one location and can accommodate its connection and carrying requirements. ASUS specifies a 15.6-inch, 0.78 kg ZenScreen MB166C with USB-C DisplayPort Alt Mode input; LG’s fixed 27U730A-B instead offers a 27-inch 4K screen and USB-C power delivery up to 90W. Neither specification establishes compatibility with your laptop, so check that before deciding.
Consider one if video calls, rather than screen space or desk reconnection, are the reason for changing your setup. Check the camera’s connection and system requirements alongside your employer’s peripheral rules. Logitech, for instance, publishes operating-system, RAM and connection requirements for its Brio 4K.
