Side-by-side dashboard and report users
If both landscape screens need to remain visible, start with the combined screen width, the space available on your desk and each monitor’s mounting requirements.
Who needs which setup?
Home workers who reposition their screens
If you change viewing positions or move between desk tasks and calls, look at the independent height, angle and reach adjustments you will actually use. The Health and Safety Executive advises arranging the screen and keyboard to avoid twisting your back.
Owners of larger or heavier monitors
If either display is large, deep or heavy, compare its bare-display weight with the limit for that individual arm. Published capacities for Ergotron and Humanscale models vary by model and configuration.
What matters when choosing a dual monitor stand?
Basic pole-mounted dual stand
Choose when: two compatible screens will remain mostly fixed side by side.
Trade-off: the Duronic DM252 adjusts in height and angle, but its published range ends at 27 inches per screen and it does not offer the long reach of the cited articulated arm.
Articulated side-by-side arm
Choose when: you regularly move the dashboard and report closer, farther away or to different heights.
Trade-off: Ergotron specifies its LX Dual Side-by-Side Arm for screens up to 27 inches; monitor depth above 8.9 cm may reduce its weight capacity.
Heavy-duty dual arm
Choose when: larger or heavier displays still need independent repositioning.
Trade-off: the Ergotron HX Desk Dual Monitor Arm has model-specific minimum and maximum weights for each display, and its attachment must fit the desk.
| Concern | What to check | Who this matters to |
|---|---|---|
| Screen position and adjustment | Compare height adjustment, tilt and reach with your seated viewing position. The Health and Safety Executive advises placing the screen top around eye level and the screen about an arm’s length away. | If I move between detailed dashboard work and reading a report, I need to reposition the screens without twisting towards the main one. Around 31% of consumers would put screen positioning first. |
| Monitor and desk fit | Check each screen’s VESA pattern and bare weight against its individual-arm limit; measure the desk attachment point and underside clearance. | I need to know that both monitors can attach and that the mount will fit my desk before choosing its movement features. Roughly 31% of consumers would make compatibility their primary concern. |
| Side-by-side space | Measure the combined screen width and check the intended horizontal layout, including clearance from a nearby wall or shelf. | My dashboard and report need to remain visible together without pushing the screen I use most into an awkward position. About 23% of consumers would prioritise the side-by-side layout. |
| Mostly fixed arrangement | Check the necessary adjustments and fit before choosing a simpler pole-mounted stand instead of a longer-reach arm. | If my two screens rarely move, I want a straightforward arrangement rather than reach I will not use. Around 15% of consumers would put a mostly fixed setup first. |
Buying mistakes to avoid
-
Choosing by screen inches alone
Screen size cannot establish whether an arm will hold a particular display. Ergotron specifies 3.2–9.1 kg per monitor for its LX Dual Side-by-Side Arm and notes that monitor depth above 8.9 cm may reduce capacity; other models have different limits.
Compare each monitor’s bare weight, depth and VESA pattern with the specifications for the exact mount.
-
Overlooking the desk edge and underside
Clamp ranges differ: Duronic specifies 10–88 mm desk thickness for the DM252, Ergotron specifies a 1–6.6 cm desk edge for the HX, and StarTech.com specifies a clamp of up to 60 mm for the ARMSLIMDUO.
Measure the proposed mounting point and look underneath for drawers, rails and cable trays. If considering a grommet mount, check the hole and desktop against that model’s requirements.
An obstructed clamp position may mean changing the mounting arrangement or desk setup.
-
Expecting an arm to fix the entire workstation
A movable screen does not resolve the position of the chair, keyboard and mouse. The Health and Safety Executive’s display-screen guidance addresses these together and advises against twisting your back to view the screen.
Set the screen you use most in relation to your keyboard and seated position, then use the mount’s adjustments to position the second display.
Relevant monitor-arm brands
Ergotron
Its LX and HX dual arms cover different screen sizes and individual-monitor weight ranges.
- Ergotron specifies 3.2–9.1 kg per monitor and up to 27-inch screens for the LX Dual Side-by-Side Arm; its HX Desk Dual Monitor Arm is specified for two screens up to 32 inches and 4.5–15.9 kg each.
- These limits are model-specific. Check display depth, desk attachment and the intended arrangement for the arm you choose.
Duronic
The DM252 is a pole-mounted option for a mostly fixed pair of compatible, smaller screens.
- Duronic specifies two 13–27 inch screens, up to 8 kg each, VESA 75 × 75 mm or 100 × 100 mm mounting and a clamp for desks 10–88 mm thick.
- Its published screen range does not cover larger displays; confirm that its available adjustments suit your working position.
Humanscale
Its M8 Pro and M/Flex systems offer different dual-monitor configurations.
- Humanscale lists an M8 Pro dual configuration at 0.5–5.7 kg per monitor and certain M/Flex M8 Pro dual configurations at 2.7–12.7 kg per monitor.
- Screen-size and weight limits depend on the configuration; check the exact assembly rather than relying on a brand-wide capacity.
StarTech.com
Its ARMSLIMDUO combines a dual desk mount with USB and audio pass-through.
- StarTech.com specifies VESA 75 × 75 mm or 100 × 100 mm mounting, two displays up to 32 inches and 8 kg per arm for the ARMSLIMDUO.
- Check the monitor limits and desk clamp fit independently of whether the additional connections suit your workflow.

For a two-screen desk setup, compare each monitor’s size, bare weight and VESA pattern with the MDS19 product details. Confirm that your screens fit side by side, that the stand can attach to your desk and that its lift range meets your needs.
Frequently asked questions
Should the dashboard screen sit directly in front of me?
If the dashboard is the screen you use most, position it in front of you and keep the report screen close beside it. The Health and Safety Executive advises keeping the screen and keyboard central to avoid twisting your back.
How do I check whether both monitors will fit?
Check each monitor’s VESA hole pattern, bare-display weight and size or depth against the exact stand’s individual-monitor limits. Do not assume that a stated maximum screen size alone confirms a suitable fit.
Can I clamp a dual monitor stand to any desk?
No: the clamp must suit the desk thickness and have enough unobstructed space underneath. Duronic specifies a 10–88 mm range for the DM252, while Ergotron specifies a 1–6.6 cm desk edge for the HX; inspect your intended mounting point before choosing either.
Does UK home-working guidance require my employer to provide a dual monitor stand?
A dual monitor stand is not an automatic requirement. The Health and Safety Executive says that, where display screen equipment regulations apply to a home worker, the employer should carry out an individual assessment. The appropriate workstation measures depend on that assessment.
