Who might benefit from a second screen?

People with a permanent desk

If your home workspace can keep a monitor set up, consider screen area, resolution and positioning for the documents, calls or windows you want beside your laptop. Which? discusses both smaller screens for limited spaces and larger displays for home offices.

People sharing or clearing their workspace

If your work surface is temporary or needs to be cleared, compare the monitor’s full dimensions, stand and power arrangement, not just whether it is called portable. Which? describes home-working setups in a range of domestic spaces.

People looking for a one-cable setup

If you want video, charging or peripheral connections through one setup, check what your exact laptop port supports and what the monitor can provide. Dell Support notes that USB-C features vary between laptop ports.

What should you check before buying?

Conventional desk monitor

Consider it when: the screen can stay in place and you want a dedicated area for work alongside your laptop.

Trade-off: it occupies desk space, so check the full dimensions and stand footprint.

Portable monitor

Consider it when: you need to move or put away the second screen between work sessions.

Trade-off: screen area, stand positions and power arrangements vary by model; portability does not guarantee one-cable use.

Concern What to check when buying Who this matters to
Usable screen area Compare screen size and native resolution with the windows you want open, then check the monitor and stand dimensions against your desk. When I need documents or calls visible beside my laptop, I want enough usable space without crowding the desk. Around 29% of consumers put screen area first.
Video and power connections Check the exact laptop’s video output and display limit, then match its port and cable to the monitor. If charging through the display matters, compare power delivery with your laptop’s charging requirement. If I want a working picture and possibly laptop charging through one setup, I need the laptop, cable and display to support the same arrangement. Around 24% of consumers prioritise connection and power compatibility.
Fit in a shared space Measure usable desk width and depth, including the stand footprint, and consider where a portable display will be stored. When I share a small surface or need to put the screen away, I care about its footprint and how it stands in use. Around 18% of consumers put workspace fit first.
Screen positioning Check the stand’s height and tilt adjustment. If considering an arm, confirm that the monitor mount and desk suit that specific arm. For extended desk sessions, I want to position the screen comfortably without an awkward setup. Around 17% of consumers prioritise screen positioning.
Visual detail Compare the exact model’s native resolution and relevant display specifications with your documents or non-colour-critical creative tasks. When I work with dense documents or visual material, I want to compare display detail rather than choose by size alone. Around 12% of consumers put visual detail first.

Buying pitfalls to avoid

  • Assuming every USB-C port carries video

    A USB-C-shaped socket does not by itself confirm video output or the charging support needed for a one-cable setup.

    Check the manual for your exact laptop model and match its supported video output and charging capabilities to the monitor.

  • Choosing by screen diagonal alone

    The stand, viewing distance and available surface also affect whether a monitor fits your workspace and can be positioned comfortably.

    Measure the working area and compare the full dimensions and stand positions. Check monitor, arm and desk compatibility before planning a clamp mount.

  • Assuming a portable display will work with one cable

    Portable monitors differ in their video inputs and power arrangements. ViewSonic’s VX1755 guidance describes a separate power connection when using mini-HDMI.

    Check the exact model’s inputs, supplied cables and power instructions against your laptop before choosing it.

Monitor brands to consider

Philips

The 27E1N1600AE/00 illustrates a fixed Quad HD USB-C monitor route for a desk with room for a 27-inch screen.

  • Philips specifies 2560 × 1440 resolution and USB-C power delivery for this model.
  • Check that your laptop supports video over USB-C and that the monitor’s power delivery meets your charging needs.

BenQ

The GW2490 illustrates a conventional monitor option when a roughly 24-inch screen suits the workspace.

  • BenQ specifies a 23.8-inch, 1920 × 1080 display and a 100 × 100 mm mount pattern for the GW2490.
  • Check the exact listing for its ports and stand adjustment; features can differ between models.

ViewSonic

The VX1755 illustrates a portable display route with USB-C and mini-HDMI inputs.

  • ViewSonic specifies a kickstand and a weight of 1 kg for the VX1755.
  • The VX1755 manual describes separate power considerations for mini-HDMI, so do not assume that every connection will work with one cable.

Lenovo

The ThinkVision M14d illustrates a smaller portable display for a laptop-based workspace.

  • Lenovo lists a 14-inch, 2240 × 1400 screen, two USB-C ports and up to 65 W power pass-through for this model.
  • Check that your laptop supports the required video connection and that the power arrangement suits your charging needs.

Dell

The Pro 27 Plus P2725QE illustrates a fixed 27-inch 4K USB-C hub-monitor route for a desk setup.

  • Dell specifies 3840 × 2160 resolution, an adjustable stand and 90 W USB-C power delivery for this model.
  • A larger, higher-resolution hub monitor still needs enough desk space, and its connections depend on the connected laptop.

iiyama

The ProLite XUB3293UHSN-B5 illustrates a larger fixed-screen route with a USB-C dock and KVM switch.

  • iiyama describes those connections for this particular 32-inch model.
  • Check that the display fits your workspace and that your laptop supports the docking functions you intend to use.

Frequently asked questions

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

No. Check the manual for your exact laptop to confirm that the port supports video, then match it to the monitor and cable. If you also want to charge the laptop through the display, compare the monitor’s stated power delivery with the laptop’s charging requirement.

Can a portable second screen work with HDMI?

Only if the particular monitor has a compatible input and a suitable power arrangement. For example, ViewSonic’s VX1755 has mini-HDMI, and its manual describes a separate power connection when using that input.

How should I position an additional screen?

For prolonged desk use, the Health and Safety Executive advises positioning the top of the screen around eye level and about an arm’s length away. Arrange the laptop and display so you can work without sustained twisting, and consider suitable input devices for extended use.

Will a dock let every laptop run more external monitors?

No. The supported number depends on the laptop and display configuration. Apple says a supported hub does not increase the maximum number of external displays for a MacBook Air, so check the guidance for your exact model.

What should I check about returns when buying online?

For an applicable UK online consumer purchase, GOV.UK guidance describes a right to cancel up to 14 days after delivery without giving a reason. Faulty-goods remedies are separate; check the applicable seller terms and any manufacturer warranty independently.
