For a dashboard beside a report, consider a side-by-side dual arm if both screens need to remain adjacent and can be positioned at a similar height. A crossbar or more configurable arm may suit a shared desk or different monitor requirements, but choose only after checking each screen’s mounting pattern and weight against the exact arm, and confirming that its attachment fits the desk.
Who this setup suits
Dashboard-and-report desk workers
Keeping a live dashboard beside a report calls for an adjacent layout that lets both screens be aligned for reading and comparison. Ergotron describes its LX Dual Side-by-Side Arm as designed for side-by-side or low-angle views.
Shared-desk users
When people take turns at the same desk, screen height and viewing position may need to change. Check the arm’s adjustment range as well as whether its attachment suits the desk; Kensington specifies height adjustment and clamp or grommet mounting for its SmartFit Dual Monitor Arm with Crossbar and Handle.
Users with larger or heavier monitors
Screen-size and load limits vary by model and configuration. Compare both displays with the exact arm’s per-screen or combined rating before deciding whether a particular dual arrangement will fit.
What matters when choosing
For a dashboard-and-report desk, decide how the screens should sit together, then check monitor and desk fit before weighing up how often their position will change.
| Concern | What to check | Who this matters to |
| Side-by-side layout |
Check the arm’s stated layout, reach and adjustment for placing both screens adjacent at a usable viewing distance. |
If I keep a dashboard open while working on a report, I need both screens in view without repeatedly turning towards one of them; roughly 42% of consumers put that layout first. |
| Monitor and desk fit |
Check each screen’s weight and rear mounting pattern against the exact arm, then confirm the desk suits its clamp or grommet fitting. |
If my screens or desk cannot accept the mount, the intended layout will not help; around 25% of consumers put physical compatibility first. |
| Easy repositioning |
Check height and movement range, particularly if different users need to reset the screens. |
At a shared or sit-stand desk, I want to change screen position without a fiddly adjustment; about 33% of consumers put easy repositioning first. |
Buying pitfalls
-
Choosing by screen size alone
A screen can be within an arm’s stated size range but exceed its load rating. Joybuy’s monitor-mount guidance highlights this distinction.
Compare each monitor’s stated weight with the exact arm’s per-screen or combined capacity, as applicable.
-
Assuming both screens have the same rear fitting
A mounting plate will not attach directly to a screen with a different rear interface. Fellowes lists 75 × 75 mm and 100 × 100 mm VESA plates for its cited Tallo range, but that does not establish the fitting on your monitors.
Check both monitor manuals or rear panels, and confirm whether the arm includes the required hardware or an adapter is needed.
-
Overlooking the desk attachment
A clamp needs a suitable desk edge; a grommet fitting needs a suitable opening. Desk structure and space behind the screens can also affect placement.
Compare the mount’s attachment requirements with the desk thickness, edge or hole, rear clearance and cable space before ordering.
-
Expecting the arm to fix the whole workstation
Moving the screens alone may still leave the keyboard poorly placed or require you to twist towards a display.
The Health and Safety Executive advises positioning the top of the screen around eye level, keeping it about an arm’s length away and avoiding a twisted working position. Check the chair and keyboard position alongside the screens.
Relevant brands to consider
Ergotron
Its LX Dual Side-by-Side Arm is intended for adjacent or low-angle screen views.
- Ergotron specifies two screens up to 27 inches, a combined load up to 18.1 kg and extension up to 64 cm for the cited model.
- Those limits belong to that model; check another arm’s specifications separately if your screens are larger or heavier.
Fellowes
The Tallo range offers monitor-arm configurations with different desk attachment options.
- Fellowes lists screens from 1 to 9 kg and up to 40 inches, with 75 × 75 mm and 100 × 100 mm VESA quick-release plates for the cited range.
- Choose the exact dual-arm variant and confirm whether its clamp, grommet or top-mount option fits your desk.
Kensington
Its SmartFit Dual Monitor Arm with Crossbar and Handle is an option to examine where screen height changes between desk users.
- Kensington specifies up to two 32-inch monitors weighing up to 9 kg each, gas-spring height adjustment and a C-clamp or grommet base for this model.
- Confirm both monitors’ fittings and weights, and whether the chosen attachment suits the desk; these specifications do not apply to every Kensington arm.
Humanscale
The M8 Pro is a configurable arm line described by Humanscale for conventional and sit-stand desks.
- Humanscale describes an optional crossbar configuration supporting two monitors up to 12 lb each.
- That dual-monitor load applies to the stated configuration; confirm the configuration, mounting fit and desk attachment for the setup you intend to use.

Frequently asked questions
What should I check before buying a dual monitor arm?
Check each monitor’s weight and rear mounting pattern, including whether an adapter is needed. Then compare the arm’s attachment requirements with the desk edge or grommet opening and allow room behind the screens for cables and ports.
Is monitor size enough to tell whether an arm will fit?
No. A screen must also meet the exact arm’s load rating and mounting requirements. Joybuy’s monitor-mount guidance notes that a display can fit a stated size range yet exceed the weight limit.
How should I position two screens for regular desk work?
Position them so you can use the dashboard and report without repeatedly twisting towards either screen. The Health and Safety Executive advises keeping the top of the screen around eye level, the screen about an arm’s length away and the screen and keyboard central; the chair and keyboard position matter too.
Does an employer need to assess a two-monitor workstation?
For workers who use display screen equipment daily as part of their normal work for continuous periods of an hour or more, the Health and Safety Executive says employers must carry out a workstation assessment. Fitting a monitor arm does not replace that assessment.
