Choose a single-monitor arm only after checking the screen’s weight and VESA fixing, and whether the mount fits the desk. For shared accounts work, look for enough adjustment to centre the display for each user while leaving room for invoices; a higher-capacity model is relevant if the screen exceeds a standard arm’s stated limits.
If accounts are on screen while invoices and statements stay on the desk, the arm needs to let you centre the display without taking over the document area. The Health and Safety Executive advises placing the screen directly in front of the user, with its top around eye level.
When colleagues use the same workstation, adjustable height, depth and angle can help each person set the screen for their own position. The Health and Safety Executive advises workers who regularly change desks to carry out a basic risk assessment when hot-desking.
A large, curved or ultrawide display used for dense spreadsheets needs an arm matched to its actual weight and mounting pattern. Screen diagonal alone does not establish whether a particular arm will fit.
Establish whether the arm fits the monitor and desk before weighing how easily colleagues can reposition the screen and how much working space remains for invoices.
| Concern | What to check | Who this matters to |
|---|---|---|
| Screen position | Check lift, reach, tilt and swivel against the position needed for the screen and paperwork. | If I read accounts beside paper invoices, I need the display in front of me rather than repeatedly turning towards it; around 29% of consumers put screen position first. |
| Shared-user adjustment | Check the stated adjustment range and whether the arm remains stable in the positions staff will use. | When colleagues take turns at the desk, I need to reset the screen without a struggle; about 24% of consumers put easy adjustment first. |
| Monitor and mount fit | Compare the screen’s weight and VESA pattern with the arm’s limits, then measure the intended clamp or grommet location. | With my existing screen and desk, I need a mount that fits both and holds the display within its rated range; around 29% of consumers put load and mounting compatibility first. |
| Invoice space | Check desk depth, rear clearance and the arm’s movement path against the space needed for documents. | For invoice batches, I want paper within reach without the arm crowding the work surface; roughly 18% of consumers prioritise usable desk space. |
A screen can fall within an arm’s stated size limit but outside its supported weight range. Ergotron also says that monitors above 9.1 kg can reduce the LX Desk Monitor Arm’s vertical travel by up to 11 cm.
Compare the actual monitor weight and VESA pattern with the exact arm model, including any load-related limits on movement.
Desk-edge dimensions and obstructions such as cable trays or panels can prevent the mount from fitting where the screen needs to sit.
Measure the intended mounting point and check any furniture restrictions. Consider a grommet fitting only if the hole and its position meet the selected arm’s requirements.
Moving the screen does not also set the chair, keyboard, mouse or glare conditions. The Health and Safety Executive advises assessing display-screen-equipment workstations and reducing risks.
Set up the screen alongside the rest of the workstation, and give people sharing the desk a way to check their own position.
On a shallow desk, an arm’s movement path may interfere with a shelf or partition, or occupy space needed for invoices.
Map where the screen will rest and move before choosing an arm’s reach, allowing for the documents used during accounts work.
Ergotron’s UK-listed LX Desk Monitor Arm is an adjustable option for a single display.
Kensington lists office arms ranging from the SmartFit Ergo Single to adjustable and heavy-duty models.
Humanscale lists single and multi-monitor office arms, including M2 Pro and M8 Pro models.
Not necessarily: an arm is one way to make a screen adjustable, not a substitute for assessing the workstation. The Health and Safety Executive says employers must assess display-screen-equipment workstations and reduce risks; consider an arm where it helps the people using this desk position the display appropriately.
Place the screen directly in front of the user, with its top around eye level and the display about an arm’s length away, as the Health and Safety Executive advises. Keep the current invoice batch close enough to consult without repeatedly twisting away from the screen.
Record the monitor’s actual weight and VESA pattern, then measure the desk edge or grommet hole at the proposed mounting point. Compare those measurements with the chosen model’s fitting requirements, and check for obstructions behind or beneath the desk.
It can if that monitor meets the particular arm’s weight and mounting requirements; screen diagonal alone is not enough to decide. Humanscale lists different supported weight ranges for its M2 Pro and M8 Pro, while Ergotron says heavier monitors can reduce the LX’s available vertical travel.
Each user should be able to check and reset the screen position along with the rest of the workstation. The Health and Safety Executive advises workers who regularly change desks to carry out a basic risk assessment when hot-desking; an adjustable arm can help with screen positioning but does not replace that check.
