Who a second screen suits

Desk-based multi-window workers

If you regularly keep a document, spreadsheet, meeting or work application open alongside another, a fixed external monitor is worth assessing. Check that the screen can sit at a suitable height on your desk.

Space-limited hybrid workers

If you use a compact desk or change workspaces, compare the footprint of a smaller fixed screen with the convenience of a portable monitor. A clamp-mounted option also depends on a suitable desk edge.

Single-cable laptop users

If you want one desk connection for a display, charging and peripherals, check what your exact laptop port supports. The monitor or dock, cable and laptop must all support the functions you intend to use.

What to check before choosing

Fixed monitor

Choose when: You repeatedly work across several windows at one desk and can leave the display set up there.

Trade-off: It occupies a regular desk position, so the stand or mount must fit both the space and your intended screen placement.

Portable monitor

Choose when: You need the extra display in different rooms or work locations rather than at one permanent desk.

Trade-off: Its smaller screen provides less space for persistent windows, and a one-cable arrangement depends on compatible ports and power.

A dock or display adapter solves a connection need, rather than replacing the second screen. Before adding one, check whether the laptop connects directly to the display and whether you need extra ports or laptop charging.

Concern What to check Who this matters to
Space for concurrent work Consider how often two work items must stay visible, then check screen dimensions, resolution and desk footprint. I need to keep a spreadsheet beside a document rather than switch windows throughout the task; around 33% of consumers put concurrent work first.
Screen position Check stand adjustment or suitable mount options, and measure the usable desk surface. The Health and Safety Executive advises placing the screen directly ahead, with its top at eye level and roughly an arm's length away. If I work for long periods at one desk, I need a screen I can position without twisting to see it; comfortable placement comes first for around 27% of consumers.
Connections and charging Match the exact laptop's video output to the display input and cable. For one-cable charging, also check supported USB Power Delivery and the laptop maker's charging guidance. I want the display to work with my laptop, and I do not want to rely on charging the port cannot provide; around 27% of consumers prioritise connection and charging certainty.
Moving between workspaces Check portable-display dimensions, weight, support or cover, included cable and the laptop's video-capable port. When I change desks, carrying an extra screen matters more to me than keeping a larger display in one place; portability is the primary need for around 13% of consumers.

Common buying pitfalls

  • Assuming every USB-C port carries video

    USB-C describes the connector, not every function it supports. Lenovo specifies DisplayPort Alt Mode and Power Delivery for the ThinkVision M14's one-plug arrangement, while ASUS notes that some USB-C ports handle only data or charging.

    Check the laptop maker's external-display specifications, then match the laptop, cable or adapter and monitor input.

    A compatible adapter or dock may be needed instead of a direct cable.

  • Choosing screen size without checking desk fit

    A larger panel alone does not establish that you can position it comfortably. The Health and Safety Executive advises keeping the screen directly in front of you, with its top at eye level and roughly an arm's length away.

    Measure desk width and depth, then check the stand's adjustment range, mount compatibility and any clamp requirements.

    If the supplied stand cannot achieve the position you need, a suitable arm or alternative stand may be required.

  • Assuming USB-C charging meets the laptop's needs

    Power Delivery differs between models: LG specifies up to 60W for the 32UN880K-B, BenQ up to 65W for the GW2790QT and Dell up to 90W for the P2425HE. Those figures alone do not establish whether a particular laptop will charge as intended.

    Compare the display or dock's output with the laptop maker's charging guidance and confirm that the intended laptop port supports charging.

    You may still need to use the laptop's own charger.

  • Buying work equipment before discussing workstation needs

    The UK Health and Safety Executive says display-screen-equipment requirements can apply to permanent or long-term home workers and those who routinely split their time between home and a workplace. It says employers must assess workstations where staff use display screen equipment daily as part of normal work for continuous periods of an hour or more.

    If that describes your work, ask your employer about its workstation assessment process before assuming a monitor you choose yourself addresses the workstation need.

Relevant brands to consider

Dell

Dell has fixed-desk models with different connection and adjustment options.

  • Dell specifies a 23.8-inch FHD IPS panel and height, tilt, swivel and pivot adjustment for the P2425H.
  • The P2425H's USB-C port is downstream and data-only, with up to 15W Power Delivery; do not confuse it with the separate P2425HE USB-C hub model, which Dell specifies with up to 90W Power Delivery.

LG

The 32UN880K-B is a fixed-display option for a desk that can accommodate its panel and clamp-mounted stand.

  • LG specifies a 31.5-inch 4K IPS panel, a C-clamp stand with multiple adjustments and USB-C Power Delivery up to 60W.
  • Check the desk edge and available space before choosing the clamp arrangement, as well as the laptop's charging needs.

BenQ

The GW2790QT combines a fixed 27-inch screen with stand adjustment and USB-C connection features.

  • BenQ specifies QHD resolution, height, tilt, pivot and swivel adjustment, and USB-C data transfer with up to 65W laptop charging.
  • Confirm that the exact laptop supports the intended video and charging functions; a USB-C connector alone does not establish compatibility.

Frequently asked questions

When is a second screen worth using instead of my laptop display alone?

A second screen is worth considering when you regularly need two or more work items visible together, such as a document beside a spreadsheet or meeting notes beside a call. For prolonged laptop work, the Health and Safety Executive advises using a separate screen with a separate keyboard and mouse so the screen can be elevated; occasional single-window tasks may give you less reason to add a display.

Will any USB-C laptop work with a USB-C monitor?

No: a USB-C connector alone does not confirm video output or laptop charging support. Check the exact laptop model's external-display capabilities, then match the monitor and cable or adapter; DisplayPort Alt Mode is one way a supported USB-C connection can carry video.

Where should I place a second screen at home?

The Health and Safety Executive advises positioning the screen directly in front of you, with its top at eye level and about an arm's length away. Check whether the stand or a suitable mount can achieve that position on your desk without displacing your keyboard and mouse.

Should I ask my employer about a home workstation assessment?

Yes, if you routinely work from home and use display screen equipment daily as part of normal work for continuous periods of an hour or more, ask about your employer's assessment process. The UK Health and Safety Executive says home-working display-screen-equipment requirements can apply to permanent or long-term home workers and workers who routinely split their time between home and a workplace; an assessment helps identify what action is appropriate for your workstation rather than automatically calling for a monitor.
