Who needs which layout?

Window-side presenters

If reflections change as daylight moves, you need to alter a screen’s angle without disrupting the display beside it. The Health and Safety Executive advises arranging screens and lighting to avoid reflections and glare.

Notes-and-slides multitaskers

Keeping presentation material on one display and notes or prompts on the other makes separate positioning useful, especially when one screen is viewed more often. The Health and Safety Executive’s workstation guidance also emphasises a comfortable position for the main screen.

Desk-compatibility-first buyers

A drawer, cable tray, shallow edge or lack of space behind the desk may determine where a mount can go. Check the requirements of a clamp, grommet or top-mount attachment against the desk before settling on an arm design.

What should you check before buying?

For notes and slides beside a bright window, decide how often each display needs to move. Then check that the chosen stand fits both monitors and its intended position on the desk.

Concern What to check Who this matters to
Separate positioning Check each screen’s tilt, swivel and height adjustment, plus clearance for the arms to move near the window. As the light changes, I need to turn the affected display without losing sight of my notes or slides; roughly 36% of consumers put separate positioning first.
Viewing position Compare height travel and reach with where you sit and which display you use most. I want the main display in front of me and the notes screen close enough to read comfortably; around 29% of consumers prioritise viewing position.
Monitor and desk fit Check each monitor’s VESA pattern and weight against its arm, then measure the desk for the specified attachment. Before choosing where the screens will sit, I need to know that both displays and the desk can take the mount; about 21% of consumers make compatibility their primary concern.
Stable two-screen layout Check that the stand accommodates the intended side-by-side arrangement and offers the adjustment you will actually use. My notes and slides need a dependable place, but I rarely expect to move either screen; roughly 14% of consumers put a simpler fixed layout first.

Common buying mistakes

  • Choosing by screen size alone

    A monitor can fall within a stated size range yet have mounting holes that do not fit, or exceed the load limit for its arm.

    Check the VESA pattern and weight of each display against the exact stand’s per-screen requirements.

  • Assuming any clamp will fit the desk

    Desk thickness, edge shape and structures underneath can prevent a clamp from seating as intended.

    Measure the usable edge and inspect beneath it. Consider a grommet or top-mount option only if its own desk requirements are met.

    If the edge cannot take the chosen clamp, using a compatible grommet mount may require installation work on the desk.

  • Expecting the arm alone to remove glare

    Reflections also depend on the window, lighting and screen placement. The Health and Safety Executive advises adjusting screens and lighting together.

    After mounting, check both displays at the times when reflections occur and adjust the surrounding layout as needed.

  • Choosing a largely fixed stand for a changing layout

    A pole-based arrangement may suit screens that stay put, but frequent changes to one screen’s angle or height call for closer attention to independent adjustment.

    If daylight or a change of user regularly alters your viewing position, check the movement available to each display before ordering.

Brands to consider

Ergotron

Ergotron offers an LX Dual Stacking configuration with a top-mount C-clamp.

  • Its top-surface attachment is worth checking if access beneath the desk is restricted.
  • Confirm the exact LX configuration, display capacity and desk requirements; the mounting method alone does not establish fit.

Fellowes

Fellowes offers dual-capable monitor-arm lines including Tallo and Eppa.

  • Fellowes lists a 1–9 kg screen range and 32 cm of dynamic height movement for Tallo, giving buyers model-specific figures to compare with their displays.
  • Capacity and attachment options vary between Fellowes lines; check the particular arm and mounting configuration.

StarTech.com

The StarTech.com ARMDUAL2 is a pole-based articulated option for two displays.

  • StarTech.com lists support for monitors up to 32 inches and 8 kg per arm for the ARMDUAL2, with clamp or grommet attachment.
  • Its pole-based height arrangement and desk attachment should be checked against the positions you need, rather than treated as specifications for other StarTech.com mounts.

Duronic

Duronic’s DM352 is a pole-mounted option for a two-screen desk layout.

  • Duronic specifies a 5–68 mm desk-thickness range for the DM352’s standard clamp.
  • The DM352’s stated 13–27 inch screen range must be checked against both displays; larger monitors call for a different suitable model.

Humanscale

Humanscale offers adjustable monitor arms with configuration-specific dual-screen options.

  • A configured adjustable arm may be worth considering when the two screens need regular repositioning.
  • Check the exact arm, any required crossbar and the permitted weight of each screen; a dual-screen claim for one configuration does not apply to every mount.

Joybuy products for this setup

This dual-monitor stand is a product to consider for keeping notes beside presentation material. Check its movement and desk fit against the bright-window position before choosing it.

DELL Pro Dual Monitor Stand MDS19

DELL Pro Dual Monitor Stand MDS19

Consider this two-display stand for keeping notes and slides visible together. Before relying on it to change screen positions beside the window, confirm its vertical movement range, how it attaches to your desk, and whether each monitor’s weight and mounting holes fit.

Frequently asked questions

Will a dual monitor arm solve glare from a bright window?

Not by itself. Adjusting each screen can help you change the angle of a reflection, but the Health and Safety Executive advises arranging screens and lighting together to avoid glare. Check the layout when the window light is most troublesome.

Where should I put the notes screen?

Keep the display you use most directly in front of you, with the notes screen nearby so you can refer to it without repeatedly twisting. The Health and Safety Executive’s standard workstation guidance places the top of the main screen around eye level and the screen about an arm’s length away; adjust the arrangement to a comfortable viewing position.

What should I measure before ordering a stand?

Check each monitor’s VESA mounting pattern and weight, then measure the usable desk edge and inspect the space beneath and behind it. Attachment requirements differ by model: Duronic, for example, specifies a 5–68 mm clamp range for the DM352, while StarTech.com lists clamp and grommet options for the ARMDUAL2.

Is the stated screen-size range enough to establish compatibility?

No. Both monitors must also meet the exact stand’s mounting-pattern and per-arm weight requirements. A screen-size claim does not establish that its VESA holes match or that its weight falls within the relevant limit.

Does regular screen work require a workstation assessment?

For workers who use display screen equipment daily as part of normal work for continuous periods of an hour or more, the UK Health and Safety Executive says employers must carry out a workstation assessment. A monitor arm is one possible workstation adjustment, not a substitute for assessing the whole setup and the work being done.
