Choose an independently adjustable dual arm if you regularly move both the call and script screens; a dual pole mount can suit a side-by-side layout that rarely changes. If the call screen is already well positioned, one separate arm for the script screen may be enough. Whichever arrangement you choose, check each monitor’s weight and mounting pattern, the desk fit and the space needed to move the screens.
Keep the call display as your primary screen and place the script or notes alongside it. The Health and Safety Executive advises positioning the main screen directly in front, with its top around eye level and the screen about an arm’s length away.
If you change screen height, distance or angle between calls and other work, look at how independently each display can move. Compare the stated movement range with the positions you actually need.
Moving two displays onto a mount still requires room for its hardware. Check desk thickness, space beneath the edge, each monitor’s weight and its VESA mounting pattern before choosing an arm.
Choose when: Both displays need to move separately as you switch between calls, reading and other work.
Allow for: Space around the desk for the intended movement and adjustment to suit each monitor’s weight.
Choose when: The call and script screens normally stay side by side at one working height.
Allow for: Height adjustment on a pole is not the same as independently lifting each screen during use.
Choose when: The main call screen already sits at a suitable height and distance, and only the script display needs moving.
Allow for: The two displays still need to work together as one viewing arrangement.
| Concern | What to check | Who this matters to |
|---|---|---|
| Call-screen position | Check whether the mount lets the call display stay in front while the script display sits at a readable side angle. | If I read prompts during a call, I want the call screen to remain my primary display rather than shifting it aside. Around 36% of consumers put that position first. |
| Monitor and desk fit | Compare each screen’s stand-free weight and VESA pattern with the mount’s limits; measure the desk for the specified clamp or grommet fitting. | With two different monitors, I need to know that each one and the desk can take the proposed mount. Compatibility comes first for around 29% of consumers. |
| Screen movement | Check each screen’s stated lift, reach and angle adjustments against the positions you intend to use. | When I change from calls to reading or shared-desk work, I need to move a display without rearranging the whole setup. Around 21% of consumers prioritise repositioning. |
| Installation space | Measure clearance behind and beneath the desk, including space for cables and the screens’ movement. | At a compact desk, I want the screens supported without a fitting that clashes with drawers, bars or nearby space. Desk installation is the first concern for around 14% of consumers. |
A diagonal size does not establish mounting or weight compatibility. Ergotron specifies a 3.2–9.1 kg range per monitor and VESA 75 × 75 mm or 100 × 100 mm for its LX Dual Side-by-Side Arm; it also warns that monitor depth above 8.9 cm may diminish capacity.
Check both monitors’ stand-free weights, rear mounting patterns and depths against the exact arm you plan to buy.
A lighter script display does not make up for a call display outside an individual arm’s supported range. The stated limit may apply to each monitor rather than their combined weight.
Check each display separately, including any depth or accessory conditions in the manufacturer’s specification.
Clamp dimensions vary by model. Duronic specifies a 5–68 mm desk-thickness range for the DM352, which should not be applied to other mounts.
Measure the desktop and inspect the space beneath its edge. If considering a grommet fitting, check the chosen mount’s hole and desk requirements too.
A mount can help position displays, but it does not settle the placement of the keyboard, mouse, chair or other parts of the workstation. The Health and Safety Executive’s display screen equipment guidance considers the wider setup.
After installation, check the primary screen’s height and viewing distance as part of the full workstation arrangement. Where an employer workstation assessment applies, raise any continuing discomfort through that process.
Ergotron offers several monitor-mount layouts. Its LX Pro Desk Dual Direct Arm is an example to examine when both call and script displays need separate adjustment.
The DM352 is a pole-mounted dual-screen option to consider when the call and script displays usually remain side by side.
Humanscale’s configurable M2 Pro arm range is relevant if you are considering a separately selected arm for the script display.
This dual monitor stand is a product choice for placing a call screen and script screen on one support. Check its fit and adjustment details against your own monitors and desk before ordering.

Consider this stand if you want the call and script displays on one support. Confirm each monitor’s stand-free weight and VESA pattern, the stand’s lift specification and how it fits your desk before buying.
Keep the call screen in the primary viewing position and place the script screen beside it at a readable angle. The Health and Safety Executive advises positioning the main computer screen directly in front, with its top around eye level and the screen about an arm’s length away; using that position for the call display is a practical application of its guidance.
No; check the mounting pattern and stand-free weight of each monitor against the exact arm. For example, Ergotron specifies VESA 75 × 75 mm or 100 × 100 mm and 3.2–9.1 kg per monitor for its LX Dual Side-by-Side Arm, and warns that monitors deeper than 8.9 cm may diminish capacity.
Measure the desk-edge thickness and look underneath for bars, drawers or cable trays that could obstruct the fitting. Compare those measurements with the chosen model’s specification: Duronic, for instance, lists a 5–68 mm clamp range for the DM352.
A monitor arm is not the requirement described in the Health and Safety Executive’s guidance. HSE says employers must carry out a workstation assessment for workers who use display screen equipment daily as a normal part of work for continuous periods of an hour or more; an arm may be considered as part of addressing the assessed setup.
No; check the terms for the exact model and purchase channel. Ergotron lists a 10-year warranty for the LX Pro Desk Dual Direct Arm, but that figure should not be assumed to apply to its other arms.
