For a calendar and email that usually stay side by side, choose a dual mount only after checking each screen’s weight and mounting pattern against the stand’s specifications. A synchronised crossbar suits screens you want to keep aligned; independent arms suit layouts you change regularly. Check the desk fixing too, because compatible monitors do not mean a clamp will fit your desk.
If both landscape screens stay in place through planning, email and task work, look for a stand that lets you align them at a workable height. The Health and Safety Executive advises positioning a work screen with its top around eye level and about an arm’s length away.
If you share a desk, turn one screen to portrait or reposition a display for screen sharing, check whether each monitor can move independently. A stand designed to keep two screens aligned may not give you the movement you need.
If either display approaches a stand’s stated size or load limit, compare both monitors with the exact model’s supported range. A maximum screen size alone does not establish that the mount will suit their weights.
Start with the fit of both monitors and the desk, then decide whether the screens will stay aligned or need to move separately.
| Concern | What to check | Who this matters to |
|---|---|---|
| Screen position | Check the available height adjustment and whether both screens can sit at a workable viewing distance. The Health and Safety Executive advises a screen top around eye level. | When I work between a calendar and email for long periods, I want to see both screens without repeatedly twisting or looking down; around 29% of consumers would put screen position first. |
| Monitor and desk fit | Compare each display’s VESA pattern and mounting weight with the stand’s limits, then measure the desk edge or grommet position for the stated fixing. | If my monitors fit the arms but the clamp cannot attach to my desk, the stand will not serve my setup; about 29% of consumers would make monitor-and-desk fit their primary concern. |
| Layout flexibility | Decide whether the screens will remain level and side by side or whether one needs independent movement, portrait rotation or stacking. | I sometimes turn or share one screen while leaving the other in place; roughly 24% of consumers would prioritise the ability to change the layout. |
| Simple installation | For a mostly fixed arrangement, check that the stand fits both screens and that its supplied fixing suits the desk. | My two smaller screens usually stay in one position, and I want a straightforward way to mount them; around 18% of consumers would put simple installation first. |
Two stands that accept the same screen diagonal can have different load requirements. StarTech.com specifies up to 8 kg per display for its ARMSLMBARDUO and ARMDUALPIVOT models, while Ergotron publishes a 4.5–15.9 kg supported range for the HX Desk Dual Monitor Arm.
Check each monitor’s mounting weight and VESA pattern against the exact stand model, including any stated minimum load.
Desk-mounting ranges vary. StarTech.com specifies a 10–48 mm desk range for the ARMSLMBARDUO, while Duronic specifies a 5–68 mm clamp range for the DM352WE.
Measure the usable desk edge and look beneath it for drawers, rails or cable trays before choosing a clamp or grommet fitting.
The Health and Safety Executive’s display-screen guidance considers screen position alongside the rest of the workstation. Raising the monitors alone may still leave you reaching for a keyboard or turning to see a screen.
After installation, review viewing distance, screen height, keyboard position and glare together. At work, include the changed arrangement in the workstation assessment where applicable.
An adjustable arm may specify a load range, not just a maximum. Ergotron publishes a 4.5–15.9 kg range for the HX Desk Dual Monitor Arm, so a display below the lower limit also needs checking.
Compare the mounting weight of each display with both ends of the exact model’s stated range.
Its ARMSLMBARDUO crossbar and ARMDUALPIVOT independent-arm models address different side-by-side and changing-layout needs.
The Tallo monitor-arm range is relevant when screen size, load and height movement need closer attention.
The HX Desk Dual Monitor Arm is an option to examine for a pair of heavier compatible displays.
The DM352WE is a pole-style option for two smaller monitors that will usually remain in one arrangement.
This dual monitor stand is relevant if you want separate positioning for a calendar-and-email setup. Confirm the fit of both displays and the desk before choosing it.

Consider this dual stand if you want a calendar and email on separate displays. Before ordering, confirm that both monitors meet the mounting, size and weight requirements, and check the lift range and desk attachment against your setup.
Choose a synchronised crossbar if the two screens normally stay level and side by side; choose independent arms if you regularly move or rotate one screen without moving the other. StarTech.com specifies its ARMSLMBARDUO for synchronised adjustment and its ARMDUALPIVOT for independent side-by-side or stacked positioning.
Check each monitor’s VESA pattern, mounting weight and screen size, then measure the usable desk edge or grommet position and check for obstructions underneath. Compare those details with the exact model’s requirements; a screen that fits the arm does not establish that its clamp fits your desk.
Set the screens at a viewing distance and height that let you work without repeatedly twisting or reaching. The Health and Safety Executive advises placing the top of a work screen around eye level and the screen about an arm’s length away; review keyboard position and the rest of the workstation as well.
A stand is one possible response to a workstation need, not a conclusion to draw before assessing the setup. The Health and Safety Executive says the UK display screen equipment rules apply to workers using screens daily for continuous periods of an hour or more, and that employers should consider the whole workstation in an assessment.
