Choose an independently adjustable dual-monitor arm if the dashboard and report are on separate screens that need different angles as daylight changes. A crossbar suits two compatible screens that should stay aligned, while a single arm may suffice when both views share one monitor. Whichever arrangement you choose, check monitor and desk compatibility; moving a screen does not replace controlling light from the window.
If the dashboard and report appear on separate displays, you may need to change one screen’s angle without moving the other. The Health and Safety Executive advises arranging screens to avoid glare and bright reflections; an adjustable arm gives you positioning options alongside changes to the desk layout or window covering.
If similarly sized screens are usually viewed together, a crossbar can keep them level as the pair moves. StarTech.com describes this arrangement for its H2M1AS2 model; it offers less freedom to angle the two displays separately.
Monitor weight, VESA mounting holes, desk thickness and space around the desk edge can determine whether an arm fits. Published limits differ between the Ergotron and StarTech.com models, so check the exact configuration against your own screens and desk.
If the dashboard and report share one monitor, consider whether a single arm gives you the movement you need. For two displays, weigh separate adjustment against keeping the pair aligned, then confirm that the chosen mount fits both screens and the desk.
| Concern | What to check | Who this matters to |
|---|---|---|
| Separate positioning | Check whether each screen can be angled and repositioned independently within the arm’s stated limits. Plan how you will control direct window light too. | If reflections shift across my dashboard and report, I need to move the affected screen without disrupting the other; around 38% of consumers put separate positioning first. |
| Monitor and desk fit | Compare each screen’s stand-free weight and VESA pattern with the arm’s limits, then check desk thickness, clamping space and underside clearance. | I need to know that both screens and the desk can take the chosen mount before deciding on an arrangement; for around 31% of consumers, compatibility is the primary concern. |
| Keeping screens aligned | For a crossbar, check both displays against its size, mounting and total-load limits, and decide whether they need to move together. | When I read the dashboard alongside the report, I want the screens to stay level rather than adjust them separately; alignment comes first for around 31% of consumers. |
Displays with the same diagonal size can differ in weight and mounting pattern. Ergotron specifies a 3.2–11.3 kg range for its LX single arm and notes that vertical movement may be reduced with monitors over 9.1 kg.
Check the exact monitor’s weight without its stand and its VESA pattern against the specific arm, rather than relying on screen size.
A dual-arm setup still has limits for individual displays. Ergotron specifies 2.3–7.9 kg per monitor for the cited HX dual configuration; StarTech.com specifies up to 8 kg per monitor for ARMDUALPIVOT.
Compare each screen separately with the chosen model’s weight, size and mounting requirements.
Repositioning a display does not stop bright light entering the workspace. The Health and Safety Executive advises arranging screens to avoid glare or bright reflections, including from windows.
Consider desk orientation and curtains or blinds before choosing how much screen adjustment you need.
A crossbar helps keep two displays aligned, but that arrangement may be restrictive if reflections affect one screen differently.
Choose shared alignment for screens you intend to move as a pair; consider independent arms if each screen needs its own position.
Its specified LX single-arm and HX dual-arm configurations illustrate why the number of screens and the exact model matter.
Its cited dual-monitor models offer a choice between independent screen movement and crossbar alignment.
The configurable M8 Pro range is relevant when deciding between a single arm and an optional crossbar-supported dual arrangement.
This dual-monitor stand is relevant if your dashboard and report use separate displays and you want to position them individually. Check both monitors and your desk against its installation requirements before buying.

Consider this stand when two screens need separate positioning beside the window. Before buying, confirm each monitor’s weight and VESA fit, the desk-mount requirements and the adjustment range you need; screen movement alone will not prevent window glare.
No, not by itself. An arm can help reposition a screen, but the Health and Safety Executive advises arranging the desk and display to avoid glare or bright reflections and using curtains or blinds where needed.
Check each screen’s weight without its stand, VESA pattern and size, then measure the desk thickness and available mounting space. Limits are model-specific: StarTech.com specifies a 0.4–1.9 inch desk-thickness range for ARMDUALPIVOT, whereas Ergotron specifies 18–25 mm for the cited HX low-profile clamp configuration.
Choose a crossbar when two compatible screens should remain level and move together; consider independently movable arms when one screen needs a different angle. StarTech.com describes its H2M1AS2 crossbar as keeping the displays aligned, but you still need to check its limits against both monitors.
