Who this setup suits

Accessibility content reviewers

If you inspect interfaces, documents, dashboards or campaign assets where colour carries meaning, a consistent visual reference can support your work. It does not replace the contrast and non-colour checks described by the W3C Web Accessibility Initiative.

Shared-desk multi-device users

If colleagues bring different laptops to one desk or compare work from two computers, consider how the monitor handles connections, peripheral sharing and simultaneous viewing. The required functions depend on the computers and desk setup.

Office standardisation buyers

If the same monitor will be used regularly by different people, screen width is only part of the decision. Adjustment options, desk layout and individual workstation assessments also matter; the Health and Safety Executive provides guidance on display screen equipment assessments.

What to check before buying

Start with the evidence your colour-review work requires, then check how each computer connects and whether the display fits the desks and people who will use it. The table separates those priorities so a useful connectivity feature is not mistaken for evidence of colour accuracy.

Concern What to check Who this matters to
Colour-review confidence Check documented sRGB or Rec.709 coverage and the relevant colour mode. If colour approval depends on the display, check the exact model’s calibration report and the conditions of any stated Delta E result. When I sign off colour-dependent work, I need a repeatable visual reference without mistaking it for an accessibility test; around 33% of consumers put that need first.
Switching between computers Check USB-C video and charging compatibility with each laptop, plus whether the intended setup needs KVM peripheral sharing or picture-by-picture viewing. At a desk used by several laptops, I want to change computers without rebuilding the connections each time; around 27% of consumers make shared-device workflow their primary concern.
Workstation fit Check the screen and stand footprint, desk depth and available position adjustments. Include the actual shared setup in the organisation’s display screen equipment assessment. If different people use the display throughout the day, I need to position it for each workstation rather than inherit one fixed arrangement; roughly 20% of consumers prioritise that fit.
Side-by-side workspace Check native resolution and physical width against the browser, design files and review tools you intend to keep visible together. I want to compare an interface with its review checklist without constantly changing windows; for around 20% of consumers, usable side-by-side space is the main priority.

These checks serve different purposes. The W3C Web Accessibility Initiative explains that adequate text contrast concerns relative luminance and that information must not depend on colour alone. Colour coverage therefore helps define a display reference, not whether the content passes those checks. For shared workstations, the Health and Safety Executive says employers must assess workstations when workers use display screen equipment daily as part of normal work and continuously for an hour or more.

Buying pitfalls

  • Treating sRGB coverage as an accessibility result

    A stated colour gamut describes a display characteristic, not whether text has adequate contrast or information remains understandable without colour. Both are distinct considerations in W3C Web Accessibility Initiative guidance.

    Use the monitor for visual review, then test contrast and check that text, shape, pattern or other non-colour cues carry any essential meaning.

  • Assuming one monitor setting will suit every laptop

    A maker’s factory calibration report or Delta E claim applies under its stated conditions. Computer output settings, colour profiles, applications and lighting can affect the review environment.

    Check the report and available modes for the exact model, agree on the team’s relevant computer settings and decide when a cross-check or recalibration is needed.

  • Choosing screen width without planning the desk

    A wider display changes the space needed for its stand and the position from which each person views it. For qualifying daily display screen equipment use, the Health and Safety Executive requires a workstation assessment.

    Measure the intended desk, check adjustment or mounting options and assess the setup for the people who use it rather than keeping one fixed position.

    Depending on the desk, making room for the display may also involve an arm, cable management or changes to the workstation.

  • Assuming a USB-C socket provides a one-cable setup

    USB-C charging capability and the power a monitor can deliver vary by model. The laptop must also support the intended video connection and charging arrangement.

    Compare the exact monitor’s power-delivery and input details with each managed laptop, and check the cable required for the planned setup.

Relevant brands to consider

These examples describe particular monitor lines, not every display made by each brand. Compare the exact model’s documentation with the work your office needs to review.

BenQ

The BenQ PD3420Q is a reference point when documented colour modes, calibration evidence and KVM functionality matter at a shared desk.

  • BenQ UK specifies 100% sRGB, 100% Rec.709 and 98% P3 coverage for the PD3420Q, alongside an average Delta E of no more than 3 and a factory calibration report.
  • Those are manufacturer specifications for this model under the maker’s conditions, not proof that content reviewed on it meets accessibility requirements.

Dell

The Dell UltraSharp U3824DW is relevant when a shared office wants a larger ultrawide workspace with hub and KVM functions.

  • Dell UK lists a 3840 × 1600 IPS Black panel, 100% sRGB and Rec.709 coverage, 98% DCI-P3/P3 coverage, RJ45 Ethernet and USB-C power delivery up to 90W for the U3824DW.
  • If sign-off requires a stated Delta E result or factory calibration report, confirm the evidence required for the exact display before choosing it for that purpose.

LG

The LG UltraWide 34WR55QK-B is an example for general shared-office work that calls for a 34-inch ultrawide, laptop charging and two-source viewing.

  • LG UK specifies 3440 × 1440 resolution, sRGB 99% typical coverage, USB-C power delivery up to 65W, height and tilt adjustment, and picture-by-picture for this model.
  • For consequential colour approval, check whether the exact monitor and workflow provide the calibration evidence the team requires; stated gamut coverage alone does not answer that question.

Ultrawides for shared-office review

These Joybuy ultrawides offer different screen sizes and layouts for a shared review desk. Consider the space each one needs, then check the exact variant’s colour settings and connections against the team’s workflow before using it as a colour reference.

Frequently asked questions

Can an ultrawide monitor show whether a design meets accessibility requirements?

No: it can support visual inspection, but its colour specifications cannot establish that a design meets accessibility requirements. The W3C Web Accessibility Initiative addresses text contrast and the use of cues beyond colour; for UK government services, the GOV.UK Service Manual says WCAG 2.2 AA involves meeting all Level A and AA success criteria and using automated and manual tests.

Which colour details should I check for web and interface review?

Start with documented sRGB coverage and a suitable mode for the exact monitor; Rec.709 coverage is relevant when the work includes video. If the team makes consequential colour approvals, check whether that variant has a stated Delta E result and factory calibration report, including the maker’s conditions for those claims.

Does a shared office need to assess the monitor workstation?

Yes, when workers use display screen equipment daily as part of normal work and continuously for an hour or more, the Health and Safety Executive says the employer must carry out a workstation assessment. For a shared desk, assess the actual screen position and layout as users and desks change rather than assuming one arrangement fits everyone.

What should an office check before standardising on one monitor model?

Confirm the exact model and purchase channel, then check the applicable warranty term, service route and business-support arrangements alongside the team’s technical requirements. Dell’s warranty information describes Standard Service or Basic Hardware Service as a minimum for its products sold for resale, but the relevant terms still need to be checked for the particular purchase.
