Who is this setup for?

One-screen script-and-call users

If the call and script share one monitor, you may need to pull the display closer for reading, then move it back without taking up more of a small desk.

Fixed-position small-desk workers

If the screen rarely moves, raising it off its original stand may matter more than having a long range of forward movement.

Two-screen call-and-reference users

If the call must stay visible while a script or notes remain open on another display, you need to plan for two screens and their mounting positions.

What matters when choosing?

Single articulated arm

Choose it when: One monitor needs to move closer for script reading and back for calls.

Allow for: Clearance behind and around the desk, as well as the chosen arm’s weight, VESA and desk-mount limits.

Pole-mounted single arm

Choose it when: Your screen mostly stays in one position and you chiefly want to adjust its height.

Allow for: The exact pole and arm configuration may offer less convenient forward-and-back movement for script reading.

Dual-monitor arm

Choose it when: The call and script routinely need to remain visible on separate monitors.

Allow for: More screen width, cables and load, with each display subject to the chosen arm’s individual limits.

Concern What to check Who this matters to
Screen movement and desk depth Check forward reach, fold-back clearance and whether cables can follow the intended movement. If I read a script on my call screen, I need to bring it closer without leaving it in the way afterwards. Around 42% of consumers would put screen repositioning and desk space first.
Monitor and desk fit Match the monitor’s VESA pattern and specified mounting weight to the arm; measure the desk for the chosen clamp or grommet base. Before I change my desk layout, I need to know the screen and mounting base will fit securely. For roughly 33% of consumers, physical compatibility would be the primary concern.
Repeatable screen position Check the adjustment range against your seated position and leave room for documents, keyboard and lighting. For regular desk work, I need a screen position I can return to comfortably without neglecting the rest of the workstation. About 25% of consumers would prioritise positioning and the wider setup.

Buying pitfalls

  • Choosing by screen size alone

    A quoted screen-size limit does not establish whether your monitor’s mounting holes and weight match the arm. Ergotron identifies VESA hole pattern and monitor weight as primary compatibility checks.

    Find the monitor’s exact VESA pattern and the weight specified for mounting, then compare both with the limits of the arm you intend to buy.

  • Overlooking the desk edge

    A compatible screen is not enough if the clamp cannot attach to the desk. For example, Ergotron specifies a 1.2–3.2 cm desk edge for one LX under-mount C-clamp variant; other bases have their own requirements.

    Measure the edge and check underneath for drawers, rails or cable trays. Make sure there is access to fit the base and space for the arm to move.

    If that clamp does not fit, you may need a different mounting base rather than the arm configuration you planned to use.

  • Buying a dual arm for an occasional script

    Two displays need more width and bring additional load and positioning constraints. A second arm position is useful only if separate screens need to remain visible together.

    If you usually switch tasks on one screen, check whether a single movable arm meets that need before planning a dual setup.

    A second display also needs room for its cables and power connection.

  • Treating the arm as the whole workstation

    Moving the monitor does not by itself resolve the placement of the chair, keyboard, documents or lighting. The Health and Safety Executive’s display screen equipment guidance considers the wider workstation and task.

    Set those elements up together. For qualifying regular work use, include the arrangement in the employer’s workstation assessment.

Relevant brands to consider

Ergotron

The LX range includes desk-mount variants with different attachment options, making the exact base important for a small desk.

  • Ergotron lists the LX Desk Mount for 3.2–11.3 kg monitors with 75 × 75 mm or 100 × 100 mm VESA mounting and 33 cm of lift.
  • Those figures do not apply to every LX variant. Ergotron says vertical travel can reduce with monitors above 9.1 kg, so check the specification for the chosen model.

Fellowes

The Tallo range includes single- and multi-monitor configurations, with gas-spring and pole-mounted options.

  • Fellowes describes the Tallo range as supporting 1–9 kg screens up to 40 inches, with 32 cm of dynamic height movement on its gas-spring arms.
  • Check the weight range, movement and mounting base of the specific Tallo configuration rather than applying range-level details to every arm.

Humanscale

Its M-Class range includes single-monitor arms with differing load ranges as well as multi-monitor systems.

  • Humanscale lists the M2 Pro single arm for 2.3–10 kg monitors and the M8 Pro for 4.1–22.7 kg monitors.
  • The lower limit matters as well as the upper one: compare your monitor’s specified mounting weight with the exact arm before choosing it.

Frequently asked questions

What should I measure before buying a desk-mounted monitor arm?

Check the monitor’s VESA hole pattern and specified mounting weight, then measure the desk for the attachment method you plan to use. For a clamp, check edge thickness, clearance underneath and access to fit it; for a grommet mount, check the hole against that base’s requirements.

Can an arm make a script easier to read during calls?

An articulated arm can help you position a compatible screen closer or slightly to one side, provided its stated reach and your desk clearance allow that movement. Leave space for the keyboard and camera, and check the screen position for glare; the Health and Safety Executive also advises allowing workspace for documents.

Does a work setup like this need a workstation assessment?

In the UK, the Health and Safety Executive says employers must assess workstations for workers who use display screen equipment daily as part of normal work, continuously for an hour or more. The assessment covers the workstation, work conditions and task, not just the monitor arm.

What should I do if I change the monitor later?

Recheck the replacement monitor’s VESA pattern and mounting weight against the arm’s limits before fitting it. Follow the exact arm model’s instructions for installation and adjustment; the Health and Safety Executive advises revisiting a workstation assessment when the equipment or the way it is used changes.
