Who may benefit from a second screen?

Multi-window laptop workers

If you need documents, spreadsheets, messages or reference pages visible together, consider how much additional readable screen space suits your work. LG and BenQ’s model specifications illustrate how resolution can differ between monitors of the same stated screen size.

Frequent laptop undockers

If you often move your laptop on and off a home desk, check whether its exact port supports video, and whether the display or dock meets your separate charging and peripheral needs. Dell Support notes that not every USB-C port carries video; DisplayLink Support describes additional software and permission requirements for some setups.

Small-desk home workers

If desk space is limited, consider the screen’s size alongside its stand or mounting options. The Health and Safety Executive advises positioning the top of the screen around eye level and the display about an arm’s length away.

What should you prioritise?

External monitor

Choose when: you need a separate display to keep work visible alongside your laptop screen.

Trade-off: the screen and its stand take up desk space; size alone does not tell you how much detail is available.

USB-C or Thunderbolt dock

Choose when: you regularly reconnect your laptop and need the display outputs, peripherals or charging specified for that dock.

Trade-off: check the laptop’s host-port requirements and supported display count; some DisplayLink setups also require software and permissions.

Display adapter or cable

Choose when: your laptop can output video and the monitor has a different input from the cable or connection available.

Trade-off: an adapter does not add screen area or provide charging unless those capabilities are separately supported.

Monitor arm or stand

Choose when: your existing or planned screen needs a different position, or its base takes up useful desk space.

Trade-off: check the screen’s mounting pattern and weight, along with the arm’s adjustment range and desk attachment.

For a laptop-based home-work setup, compare these four priorities with the equipment and desk space you already have.

Concern What to check when buying Who this matters to
Readable workspace Compare screen size and native resolution, then consider your intended window layout and scaling. If I keep a spreadsheet beside messages and reference pages, I need enough readable workspace without a screen that overwhelms the desk. Around 33% of consumers put readable workspace first.
Laptop connection and charging Check the exact laptop’s video output, supported display count, required charging power and compatible cable. When I unplug my laptop often, I want a desk connection that matches its video, charging and display support. Around 27% of consumers prioritise laptop connection and charging.
Desk fit and screen position Measure available space and viewing distance; check stand movement or mounting compatibility. On a compact desk, I need the screen and stand to fit while still allowing a workable position. Around 20% of consumers put desk fit and screen position first.
Keeping the setup simple Inventory the laptop outputs, monitor inputs and included cables before choosing a display, dock or adapter. If my laptop already has a usable video output, I would rather add only the equipment needed than take on dock functions I will not use. Around 20% of consumers prioritise a simple, direct setup.

Buying pitfalls

  • Assuming every USB-C connection carries video and charges a laptop

    USB-C port capabilities vary. Dell Support notes that not every USB-C port supports video output, and charging needs must be checked separately from display connectivity.

    Check the exact laptop’s video-output specifications against the precise monitor or dock, and compare its stated charging capability with your laptop’s requirements.

  • Choosing a larger screen without checking resolution or position

    Two screens of the same stated size can have different native resolutions, and a stand that cannot be positioned suitably may make a home workstation awkward.

    Compare screen size and resolution, measure the desk, and check stand adjustment or mounting compatibility before choosing.

  • Expecting a dock to add displays without setup requirements

    Some docks require drivers, and DisplayLink Support says its macOS Manager needs Screen Recording permission to operate.

    Before choosing a dock, check your laptop model, intended display count, dock technology and workplace software policy.

Brands and product lines to consider

These examples describe specific product lines and models; their features and limitations should not be assumed to apply across an entire brand.

Dell

The UltraSharp U2723QE illustrates a 27-inch 4K USB-C hub monitor for a laptop-centred desk.

  • Dell specifies USB-C DisplayPort Alternate Mode, power delivery up to 90 W, USB peripherals, LAN and height, pivot, swivel and tilt adjustment for this model.
  • Check that the laptop’s video output and charging requirements match the monitor’s connection and power-delivery specifications.

BenQ

The GW2790 is an example of a 27-inch Full HD monitor with direct display connections.

  • BenQ specifies 1920 × 1080 resolution, HDMI and DisplayPort inputs, a 100 × 100 mm mounting pattern and tilt adjustment for the GW2790.
  • Check the exact model’s connection and charging details if you need USB-C video or laptop power delivery; BenQ’s eye-comfort descriptions are manufacturer claims, not evidence of a health outcome.

LG

The 27U631A-B illustrates a 27-inch QHD USB-C display where screen resolution and laptop charging need separate consideration.

  • LG specifies a 2560 × 1440 display and USB-C connectivity for this model.
  • LG specifies USB-C power delivery up to 15 W and says the USB-C cable is sold separately; check whether that power meets your laptop’s charging needs.

Lenovo

The ThinkVision T27h-30 illustrates a QHD monitor with integrated connections and an adjustable stand.

  • For part number 63A3GAT1UK, Lenovo lists USB-C, Ethernet, a USB hub, DisplayPort output and stand movement.
  • Check laptop compatibility and confirm the specifications of the exact variant offered before choosing it.

StarTech.com

The DK30CH2DPPDU illustrates a DisplayLink-based dock for a setup requiring additional display outputs, rather than a replacement for a monitor.

  • StarTech specifies three video outputs and 60 W USB-C power delivery for this product.
  • StarTech specifies driver installation for Windows and macOS; check the laptop, software requirements and workplace policy before choosing this approach.

Frequently asked questions

Will any USB-C socket on my laptop run a monitor or dock?

No. Dell Support notes that not every USB-C port supports video output. Check your exact laptop’s documented video capability and the monitor or dock’s host-connection requirements, and assess charging separately.

Can a USB-C monitor replace my laptop charger?

Only if the monitor’s specified power delivery meets your laptop’s requirements. For example, LG specifies up to 15 W for the 27U631A-B, so its USB-C connection alone does not establish that it can charge a particular laptop adequately.

How should I position a screen for home working?

The Health and Safety Executive advises placing the top of the screen around eye level and the display about an arm’s length away. Its guidance for prolonged laptop use also describes using a separate keyboard and mouse when raising the laptop screen, or using a separate display; check what position is workable at your desk.

What extra setup can a DisplayLink dock require on a Mac?

DisplayLink Support says its macOS Manager needs Screen Recording permission to access pixels for an extended or mirrored display. Check the dock’s software requirements and whether your workplace permits installation before choosing that setup.

Who pays if an assessment finds that home-working display equipment is needed?

For workers covered by the applicable display-screen-equipment rules, the Health and Safety Executive says that when an assessment indicates action is needed, such as providing equipment, workers cannot be charged. HSE guidance applies to Great Britain, while Northern Ireland has separate guidance from HSENI; this does not mean every home worker is automatically entitled to a particular monitor.

What if an online monitor purchase does not suit my setup?

For a qualifying UK distance sale, GOV.UK says you can tell the seller you wish to cancel within 14 days of receiving the item, then have a further 14 days to return it. Check the seller’s instructions and distinguish a change-of-mind return from rights relating to faulty goods.
