Who needs this setup?

Presenters keeping notes beside slides

A side-by-side arrangement keeps notes adjacent to the presentation. Check that both displays can be positioned for your usual seated or standing view.

People with fit-sensitive desks

Monitor weight and mounting holes matter alongside the space available at the desk edge. A cable tray or structure beneath the desktop can affect where an attachment fits.

Shared-desk and sit-stand users

If the working position changes during the day or between users, look at how the chosen mount adjusts and how easily both screens can be repositioned.

What matters when choosing?

For notes beside slides, choose the screen arrangement first: separate arms allow different positions, a crossbar keeps the pair aligned, and a stack changes the viewing layout.

Separate dual arms

Choose when: The notes and presentation screens need different angles, heights or orientations while remaining side by side.

Check: Each arm’s monitor limit and whether its adjustment range works with both screens in place.

Horizontal crossbar

Choose when: You want to keep the screens aligned and reposition the pair together.

Trade-off: Individual screen positioning may be more restricted; StarTech.com specifies limited individual tilt and swivel for its ARMSLMBARDUO.

Vertical stack

Choose when: Limited desk width matters more than keeping notes directly beside slides.

Trade-off: The second display sits above or below the presentation, changing the intended viewing arrangement.

Concern What to check Who this matters to
Adjacent screens Check that both displays fit side by side and whether their positions can be adjusted separately. I need to glance from slides to notes without placing one screen above the other. Around 36% of consumers put that adjacent layout first.
Monitor and desk fit Compare each screen’s weight and mounting-hole pattern with the exact mount; measure the desk at its intended attachment point. My monitors and desktop must fit the mount before its other features matter. Roughly 36% of consumers make compatibility their primary concern.
Viewing position Compare height, reach and angle adjustment with your working positions. If I change desk height or share a workstation, I need to reposition the screens for the person using them. Around 21% of consumers prioritise adjustment.
Desk organisation Check the mount’s footprint, arm reach and cable routing, particularly near a wall. I want room for presentation materials without awkwardly placed arms or cables. Approximately 7% of consumers put desk organisation first.

Buying pitfalls

  • Choosing by screen size alone

    Two monitors with the same diagonal size can differ in weight and mounting-hole pattern, so size alone cannot establish whether a particular arm fits.

    Record each screen’s weight without its original stand and its VESA mounting pattern, then compare both with the exact model’s limits.

  • Assuming the clamp fits the desk

    Desktop thickness and obstructions beneath the intended mounting point can prevent an attachment from fitting.

    Measure at that point and inspect underneath it. Consider a grommet attachment only if both the desk and chosen mount support it.

  • Stacking screens when notes must sit beside slides

    A stacked arrangement puts the notes screen above or below the presentation rather than adjacent to it.

    Prioritise a side-by-side arrangement unless saving desk width matters more to your workflow.

  • Expecting the arm to set the viewing position for you

    Adjustment is useful only if the installed screens can be placed appropriately for the working position.

    After installation, use the Health and Safety Executive’s guidance on screen height and viewing distance to check the setup, and position the main screen to avoid twisting to view it.

Brands to consider

Ergotron

Ergotron offers distinct dual-monitor arm configurations, including the LX Pro Desk Dual Direct Arm.

  • Ergotron specifies a 33 cm lift, VESA MIS-D compatibility and a 10-year warranty for that LX Pro configuration.
  • Its stated screen limit is 27 inches and 8.5 kg per monitor; check both displays against this particular model.

StarTech.com

StarTech.com lists separate-arm, crossbar and side-by-side-or-stacked dual-monitor designs.

  • Its ARMDUAL2 specifies individual articulation for two displays up to 32 inches and 8 kg each.
  • Attachment dimensions and adjustment geometry differ between models; choose by the relevant model’s specifications.

Fellowes

Fellowes includes dual and compact dual configurations in its Tallo monitor-arm range.

  • Fellowes lists VESA 75 × 75 mm and 100 × 100 mm plates and several attachment options across the Tallo range.
  • Range-wide specifications should be checked against the particular dual configuration before purchase.

Humanscale

Humanscale offers configurable M8 Pro monitor arms, including an optional dual-monitor crossbar.

  • Humanscale specifies support for two monitors up to 12 lb each with the cited optional crossbar.
  • Compare each monitor’s actual weight with the selected M8 Pro configuration rather than assuming that all dual arms have the same capacity.

This dual-monitor stand is a starting point for a two-screen presentation setup. Confirm that its screen arrangement puts notes beside slides and that its attachment fits your desk.

DELL Pro Dual Monitor Stand MDS19

DELL Pro Dual Monitor Stand MDS19

Consider this stand if you need to support two displays for slides and notes, but confirm that it allows the side-by-side arrangement you intend to use.

Check each monitor’s weight and mounting compatibility, the usable adjustment range and how the stand attaches to your desk before buying.

Common questions

Should presentation notes go beside or above the slides?

Place the notes screen beside the presentation when an adjacent view is the reason for buying a dual stand. A vertical stack changes that arrangement and is worth considering when desk width takes priority.

Does screen size tell me whether a dual arm will fit?

No. Check each monitor’s weight without its original stand, mounting-hole pattern and physical dimensions as well as its diagonal size. Compare both screens with the chosen arm’s individual limits.

How can I check whether a desk clamp will fit?

Measure the desktop at the intended mounting point and look underneath for anything that would obstruct the clamp. Then compare the measurements with the exact mount’s instructions; StarTech.com specifies a 10–48 mm desk-thickness range for its ARMSLMBARDUO, not for every clamp mount.

Where should I position the screens after installation?

Adjust them around your normal working position rather than relying on the mount’s stated range alone. The Health and Safety Executive advises placing the top of a screen around eye level and the screen about an arm’s length away; keep the main screen positioned so you do not have to twist to use it.
