Artists who frequently check references
If you move between a drawing and visual references, an arm’s reach and rotation matter when you want to bring the screen into view, then recover desk space.
Who is this choice for?
People using shared desks
When colleagues adjust the same workstation, the screen needs to be repositionable and the mounting fitting must suit the actual desktop. The Health and Safety Executive advises assessing the whole workstation, not just the screen.
Owners of large or curved monitors
A wide or heavy display calls for a check of the exact arm’s load range and screen compatibility. The capacity guides from Ergotron, Humanscale and Colebrook Bosson Saunders distinguish between arm configurations and monitor types.
What matters when choosing an arm?
Start with how often the reference screen needs to move, then establish whether the desk fitting and the monitor itself suit the arm. A fixed or limited-adjustment mount remains an option when the screen normally stays in one position.
| Concern | What to check | Who this matters to |
|---|---|---|
| Moving the reference screen | Check reach and lift against your desk layout, plus the tilt and rotation you intend to use. | I need to bring details closer while drawing, then move the display away to free the work surface. Around 36% of consumers would put frequent repositioning first. |
| Fitting a shared desk | Measure desktop thickness and check edge or through-desk access, underside obstructions and the maker’s fitting limits. | At a desk used by several people, I need a fitting that works with its actual construction before worrying about extra movement. For around 36% of consumers, desk compatibility would be the primary concern. |
| Supporting the monitor | Compare mounting weight and VESA pattern with the exact arm’s minimum and maximum load; check its stated support for a wide or curved screen. | If my reference display is heavy or curved, I want to know the selected configuration can hold that particular screen. Stable support would come first for around 28% of consumers. |
Mistakes to avoid
-
Choosing by screen size alone
A screen can fit an arm’s size guidance yet fall outside its load range. Ergotron says the LX Desk Monitor Arm’s vertical range may be reduced for monitors above 9.1 kg.
Check the monitor’s mounting weight and VESA pattern against the exact arm configuration’s minimum and maximum load. Include fitted accessories where the arm maker requires it.
-
Assuming a standard clamp will fit
A cable tray, inaccessible edge or sliding worktop can affect where an arm can be fitted. Colebrook Bosson Saunders offers different desk-fitting options for its Flo range.
Inspect the edge and underside, measure desktop thickness, and choose a fitting specified for those desk conditions.
A different fitting may need to be obtained separately from the arm.
-
Treating the arm as the whole workstation solution
Moving a screen does not also adjust the chair, input devices or lighting. The Health and Safety Executive considers these parts of the wider display-screen-equipment workstation.
After fitting the arm, arrange the whole workstation and include the changed screen position in an employer’s assessment where applicable.
Relevant monitor-arm brands
Ergotron
Its LX Desk Monitor Arm is a single-screen option to examine when frequent adjustment is the priority.
- Ergotron specifies a 3.2–11.3 kg load range, VESA 75/100 mounting and 33 cm of lift for the LX Desk Monitor Arm.
- Ergotron warns that vertical range may be reduced by up to 11 cm above a monitor weight of 9.1 kg. Check the current model and configuration before ordering.
Humanscale
Its M2 Pro and M8 Pro ranges provide different load ranges to check against a reference monitor.
- Humanscale’s UK capacity guide lists 2.3–10 kg for M2 Pro and 4.1–22.7 kg per monitor for M8 Pro in the stated configurations.
- Capacity depends on the configuration, including offset-VESA and multi-monitor arrangements; use the guide entry that matches the proposed installation.
Colebrook Bosson Saunders
Its Flo and Flo X arms address different single-screen weights and formats.
- Colebrook Bosson Saunders specifies Flo for 2–7 kg flat or curved screens up to 1000R, while Flo X supports single screens of 3–18 kg.
- Check the fitting as well as the arm: the available desk-mounting options must be matched to the desktop and may be configured separately.

Monitor-arm questions
How should I position a reference monitor after fitting an arm?
Use the arm to put the screen at a comfortable viewing position within the complete workstation. The Health and Safety Executive advises placing the top of the screen about level with your eyes and the screen about an arm’s length away; also check how the chair, desk and input devices are arranged.
Do I need my monitor’s weight before choosing an arm?
Yes: compare its mounting weight with both the minimum and maximum load for the exact arm configuration, and confirm the VESA pattern. Ergotron notes that a heavier monitor can reduce the LX Desk Monitor Arm’s available vertical movement.
Does a shared-office workstation need an assessment?
In the UK, the Health and Safety Executive says employers must assess workstations for employees who use display-screen equipment daily as a normal part of work for continuous periods of an hour or more. If a new arm changes the screen arrangement, include that arrangement when assessing the workstation.
Can an arm replace attention to lighting and breaks?
No. An arm changes where the monitor can sit, while the Health and Safety Executive also advises suitable lighting and regular breaks from screen work. Check those conditions alongside screen position.
What if the shared desk has no accessible rear edge?
Check whether the selected arm offers a suitable alternative to a rear-edge clamp. Colebrook Bosson Saunders lists different fitting options for its arms; confirm the chosen fitting’s desktop-thickness range and access requirements against the actual desk.
