Choose a dual-monitor arm when the source and translation normally occupy two external displays. A single arm is more suitable when the second reference stays on a laptop or paper; if you are considering two separate arms, check that the desk can accommodate both mounts and position both screens comfortably. For any arm, match each monitor’s weight and mounting pattern to the exact model, then check how it attaches to the shared desk.
If you keep a source and its translation open on separate monitors, assess whether a dual arrangement lets you bring both displays to a comfortable height and viewing distance. Each screen must also fit the chosen arm’s weight and mounting limits.
When colleagues take turns at one workstation, the ability to reset screen height and angle matters more than a position that suits only one person. Check the adjustment range on the exact dual-arm configuration.
If the desk has a difficult edge, a blocked underside or little room behind it, inspect the proposed mounting point before choosing an arm. Check both monitors’ weights and mounting patterns as well.
Decide whether you need two external screens together or one main monitor with a laptop or paper reference. Then check screen compatibility and desk fit before comparing adjustment features.
| Concern | What to check | Who this matters to |
|---|---|---|
| Side-by-side layout | Check that the configuration accommodates both screens at usable positions and supports each monitor separately. | I need to compare the source and translation without continually changing windows; around 42% of consumers put the two-screen layout first. |
| Shared-desk adjustment | Compare each screen’s height and angle adjustment, while checking the model’s per-monitor load range. | Different colleagues need to reset the screens to their own viewing positions; roughly 33% of consumers prioritise adjustability. |
| Monitor and desk fit | Match each stand-free monitor weight and mounting pattern, then measure the desk against the clamp or grommet instructions. | I cannot use an arm that will not attach to my displays or desk; about 25% of consumers make physical compatibility their main concern. |
A dual arm can specify a separate load range for each monitor. Ergotron lists 3.2–9.1 kg per monitor for its LX Dual Side-by-Side Arm, rather than a combined allowance that can be assigned to one display.
Compare each monitor’s weight without its stand against the exact arm’s per-screen minimum and maximum.
Desk thickness, edge shape, space underneath and clearance behind the desk can all affect installation. A grommet mount is another possibility only if the desk and arm suit that method.
Measure the intended mounting point and follow the chosen model’s fitting instructions before ordering.
A grommet installation may require drilling the desktop and can leave a permanent hole.
Ergotron marks its older LX Desk Monitor Arm as discontinued. Specifications or listings for an older LX configuration should not be assumed to describe an LX Pro variant.
Confirm the complete model name and current configuration, including its monitor limits and mounting method.
The Health and Safety Executive advises assessing the whole display-screen workstation and the work being done, not just the screen mount.
After installation, adjust the screens alongside the chair, keyboard and available desk space for each user, and include the arrangement in the relevant workstation assessment.
Ergotron’s LX Pro range includes single and dual desk-arm configurations relevant to adjustable office workstations.
Humanscale’s M/Class range includes dual and multi-monitor arrangements for offices considering different display layouts.
Fellowes lists single, dual and stacked configurations within its Platinum Series of desk-mounted arms.
The option here is a dual-monitor desk stand for using a source and translation on separate displays. If you specifically need an arm attached to the desk, confirm how this stand mounts before choosing it.

Consider this dual-display stand if you review a source and translation on separate monitors. Before ordering, confirm how MDS19 mounts, whether each display meets its weight and mounting-pattern requirements, and whether its adjustment range suits everyone sharing the desk.
No. The Health and Safety Executive says employers must assess the workstation for workers who use display screen equipment daily as part of normal work for continuous periods of an hour or more. An arm is one part of the arrangement, not a substitute for assessing the whole workstation and the work being done.
Place the primary working screen directly in front of you. The Health and Safety Executive advises positioning the top of the screen around eye level and the display about an arm’s length away; if you use two screens equally, arrange them to avoid sustained twisting and readjust them for each user.
Measure the desk thickness and check its edge, underside and rear clearance against the exact arm’s instructions. Also check each monitor’s weight without its stand and its mounting pattern; if a clamp will not fit, consider a grommet model only where the desk can accommodate its installation.
Yes, a single arm can position the main external monitor while the source remains on a laptop, provided that arrangement works for your review task. For prolonged laptop work, the Health and Safety Executive advises using a separate keyboard and mouse so the screen can be elevated.
