Choose separate monitor arms if colleagues need to position or rotate each screen independently; consider a crossbar if keeping two displays aligned as they move together matters more. Before buying, check each monitor’s weight and mounting pattern against the stand, then confirm that its clamp or grommet mount suits the shared desk.
If both versions must remain visible, look for controls that let you align their working areas. Independent rotation is worth considering when one document is easier to read in portrait orientation; StarTech.com specifies rotation on its separate-arm model.
When colleagues take turns at one desk, consider how easily each person can restore a comfortable viewing position. The Health and Safety Executive’s workstation guidance is relevant when reviewing a changed shared setup.
Check the weight of each display, its mounting-hole pattern and the desk mount, not just its diagonal size. Ergotron, Humanscale and StarTech.com publish different limits for the dual-monitor configurations described below.
Choose when: Colleagues need to move each display separately or turn one screen to portrait for a long document.
Trade-off: After someone changes the layout, bringing the screens back into alignment can take more adjustment.
Choose when: Two screens should stay level and move together for a repeatable side-by-side layout, as with StarTech.com’s ARMSLMBARDUO.
Trade-off: A shared crossbar gives less freedom to place the two displays independently, even where each screen has its own tilt or rotation controls.
| Concern | What to check | Who this matters to |
|---|---|---|
| Document alignment | Check side-by-side positioning, height adjustment and whether either display can rotate to portrait. | When comparing long pages, I want both working areas in view without repeatedly moving documents between screens. Around 50% of consumers put alignment and comparison visibility first. |
| Shared-desk adjustment | Check how the screens can be repositioned between users and whether their movement suits nearby partitions. | At a desk shared with colleagues of different heights, I need to change the viewing position without rebuilding the layout. For around 30% of consumers, easy readjustment is the primary concern. |
| Mounting compatibility | Match each monitor’s weight and VESA pattern to the stand; measure the usable desk edge or planned grommet position. | If my displays or desk might not accept the mount, I need to establish that they fit before choosing adjustment features. Compatibility is the first priority for around 20% of consumers. |
Stands advertised for the same screen diagonal can have different per-monitor weight limits and mounting requirements. A display may meet the size limit but still fall outside another limit.
Check each monitor’s weight without its original stand and its VESA mounting pattern against the exact stand model.
The usable desk edge may be too thick, too thin or obstructed. StarTech.com specifies a 40–85 mm clamp range for ARMDUAL3, while Ergotron specifies a 1–6.6 cm desk-edge range for its HX Desk Dual Monitor Arm.
Measure the intended mounting point and check for drawers, cable trays or edge structures. If considering a grommet mount, confirm that the hole and desk structure suit the model.
Screen position does not settle whether the chair, desk, keyboard and mouse work comfortably together. The Health and Safety Executive’s display-screen-equipment guidance considers the workstation as a whole.
Review the full arrangement after installation and revisit it when the shared setup changes or users report discomfort.
The HX Desk Dual Monitor Arm is a higher-capacity option for two displays that need shared repositioning.
The modular M/Flex range includes a dual M2.1-arm configuration with a two-piece clamp base.
Its ARMSLMBARDUO crossbar and ARMDUAL3 separate-arm models offer different ways to position two office displays.
For keeping two document versions visible at a shared desk, this Joybuy option is a dual-monitor stand. Check how it fits your particular monitors and desk before choosing it.

A dual-monitor stand to consider when both document versions need to stay visible. Before ordering, check each monitor’s weight and mounting pattern, the desk installation requirements and the actual lift range; do not assume tool-free fitting applies unless your monitors use the compatible Dell Quick Release system.
Check each monitor’s weight without its original stand, its VESA mounting pattern and the usable desk-edge thickness against the exact model’s limits. If you plan to use a grommet mount instead, check the hole and desk structure too; for reference, StarTech.com specifies a 40–85 mm clamp range for ARMDUAL3.
No: aim for working areas that are comfortable to scan side by side, then adjust for the documents and the person using the desk. The Health and Safety Executive’s general posture guidance places the top of a screen around eye level and the screen about an arm’s length away; rotating one display to portrait may help with long pages.
Make it practical for each user to reposition the screens and review the workstation arrangement when it changes or someone reports discomfort. Keep cables clear of moving arms, follow the manufacturer’s installation instructions and check the mount after it has been moved.
