Choose a dual-monitor arm or two single arms if the source and translation need to stay visible on separate external screens. A single adjustable arm may suffice when the second document is on a laptop or tablet; consider a higher-capacity arm only if the monitor’s weight calls for one. Check each screen’s weight, mounting holes and the desk’s mounting position before deciding, and treat screen placement as one part of the whole workstation.
If the source and translation must remain open on separate external screens, look for a way to position each display independently. A dual arm or two single arms is relevant when comparing passages throughout a task.
If the desk changes hands or tasks, consider how far the screen can move and where it sits when parked. Check that the arm, cables and neighbouring equipment leave enough room for that movement.
If either monitor or the desk has uncertain mounting dimensions, establish the screen weight, mounting-hole pattern and usable desk position before comparing adjustment features.
Choose it when: One external monitor needs regular repositioning and the other document can remain on a laptop or tablet.
Trade-off: It does not give two external screens independent positions.
Choose it when: The source and translation need to remain visible on separate external monitors during sustained comparison.
Trade-off: Both screens need suitable mounts and enough desk clearance; check each monitor’s capacity separately.
| Concern | What to check | Who this matters to |
|---|---|---|
| Both documents in view | Decide whether you need two external screens or one beside a laptop or tablet. For a dual mount, confirm that the screens can sit in your intended arrangement. | If I compare passages continuously, I want the source and translation visible without switching between them; around 38% of consumers put simultaneous viewing first. |
| Movement at a shared desk | Check reach, parked position and clearance around dividers or shelves. Leave cable slack for the intended movement. | When someone else needs the work surface, I want to move the screen without disrupting the cables; for around 31% of consumers, repositioning is the primary concern. |
| Monitor and desk fit | Check each screen’s weight without its stand against the arm’s minimum and maximum, then match its VESA holes and the desk’s clamp or grommet position. | I need to know the arm will fit my screen and mounting position before its adjustments matter; compatibility comes first for around 31% of consumers. |
For a heavier display, check the arm’s lower as well as upper weight limit and any restrictions on movement. Ergotron specifies 3.2–11.3 kg for its LX Desk Monitor Arm and notes reduced vertical movement above 9.1 kg; Humanscale lists 4.1–22.7 kg for its M8 Pro single arm. Neither range establishes compatibility with a particular monitor or desk on its own.
A screen can fall outside an arm’s weight range or have mounting holes that do not match. Ergotron’s LX Desk Monitor Arm, for example, is specified for 3.2–11.3 kg and may have less vertical movement with screens above 9.1 kg.
Check the monitor’s weight without its stand, its VESA pattern and the arm’s per-screen weight range before using screen size as a filter.
Clamp and grommet limits vary by model, and the desk itself must be suitable for the intended mounting point.
Measure the position you plan to use, check the desk manufacturer’s instructions and confirm which mounting hardware comes with the exact arm.
If that position cannot take the mount, you may need a different mounting method or desk arrangement.
A movable screen does not address every issue with lighting, chair position or keyboard placement. The Health and Safety Executive advises considering the equipment, furniture, working conditions and work together in a display screen equipment assessment.
Position the screen with the chair, keyboard and lighting in place. If the desk is used for work and discomfort persists, raise it through the employer’s workstation assessment process.
Ergotron identifies the listed LX Desk Monitor Arm SKU as being phased out. Its published specifications should not be assumed to apply to a successor or another variant.
Check the current model number, technical sheet and included mounting hardware for the product you intend to order.
Its LX Desk Monitor Arm illustrates the checks for a single adjustable display at a shared desk; the wider range also includes dual and heavier-monitor options.
Its Platinum Series includes single- and multi-monitor arrangements relevant to deciding how many external screens the desk needs.
Its single-arm and multi-monitor ranges provide options to examine when screen weight or the number of displays changes the setup.
This dual-monitor stand is worth considering if you plan to use two external screens for the source and translation. Check its intended screen arrangement and desk fit before treating it as an alternative to a dual monitor arm.

Consider this stand when the source and translation will be shown on two external monitors. Confirm that it allows your intended side-by-side arrangement and fits the available desk space; do not assume it mounts like a desk-clamped arm.
Before ordering, check the supported VESA patterns, the weight range for each monitor and the correct lift specification for this exact model.
Choose a dual-monitor arm or two independently mounted single arms if the source and translation need to stay on separate external monitors. If one document can remain on a laptop or tablet, a single arm for the external screen may be enough. Check each screen’s weight and mounting pattern, as well as the desk space needed for the arrangement.
Measure the monitor’s weight without its stand, identify its VESA mounting-hole pattern and measure the intended clamp position or grommet hole. Check those measurements against the exact arm and the desk manufacturer’s mounting guidance; one model’s limits do not apply to every arm.
No. It can change where the screen sits, but chair position, lighting, keyboard placement and the work itself also matter. The Health and Safety Executive advises considering the whole workstation in a display screen equipment assessment.
Yes, if the desk is used for work, consider the full home workstation rather than the arm alone. The Health and Safety Executive says display screen equipment regulations can apply to people who work from home long term or routinely split their time between home and a workplace; discuss an applicable workstation assessment with your employer.
