Choose an adjustable single monitor arm if calendar and email can share one screen and you need to reposition it when you switch between sitting and standing. Choose a dual-monitor arrangement if the calendar needs its own permanently visible display. Either way, check each monitor’s VESA pattern and weight without its stand, then confirm that the mount fits your desk and provides the movement you need.
If you change desk height during the day, an adjustable arm lets you reset the screen’s height and reach. The Health and Safety Executive advises positioning the top of the screen at eye level and the screen about an arm’s length away.
If adjacent windows give you enough room for both apps, one compatible monitor arm supports that layout without requiring a second display. Check that its mounting plate, weight range and desk attachment fit your setup.
If the calendar must stay visible on its own display while email occupies the main screen, consider a dual mount. Each monitor must meet its arm’s stated compatibility limits, and the desk must accommodate the mount.
Decide whether you need one physical screen or two, then check monitor and desk fit before comparing how far an arm moves.
| Concern | What to check | Who this matters to |
|---|---|---|
| Height and reach adjustment | Compare vertical travel and reach with the screen positions you need when seated and standing; check the arm’s operating weight range. | I change desk height regularly and need to bring the screen back to a workable position without remounting it. Around 36% of consumers put this adjustment need first. |
| Monitor and desk fit | Match the monitor’s VESA pattern and weight without its stand to the arm; measure desk thickness and check the edge and underside for clamp clearance. | If I am unsure whether the mount will attach to my screen or desk, fit comes before movement features. For around 36% of consumers, compatibility is the primary concern. |
| Calendar-and-email layout | Decide whether two windows on one screen are sufficient or whether you need two displays; for a dual mount, check each arm’s limits. | I want the calendar in view while handling email, so the deciding question is whether it needs a separate screen. Keeping that layout visible is the first priority for around 28% of consumers. |
A monitor can fall within an arm’s advertised screen-size limit yet have an incompatible mounting pattern or sit outside its operating weight range. Dynamic arms can have a minimum as well as a maximum load.
Find the monitor’s VESA pattern and weight without its original stand, then compare both with the specifications for the exact arm variant.
A clamp may not fit around a bevelled edge, drawer, cable tray or structural rail, even when the desktop thickness falls within its stated range.
Measure the desktop and inspect the space beneath and behind its edge against the mount’s installation drawing. Consider a compatible grommet or freestanding mount if a clamp does not suit the desk.
A dual mount serves two physical displays; it is not needed merely to place calendar and email in adjacent windows on one monitor. Two screens also mean checking the fit of both monitors.
Try the intended window arrangement before deciding whether the calendar needs a separate display.
A second display also needs its own power connection and space for mounting hardware.
Moving the screen does not address the position of the keyboard, mouse or chair, or issues such as glare. The Health and Safety Executive advises considering the whole workstation.
After installation, set the screen height and distance for your working position and check the rest of the workstation too.
These product lines illustrate different weight ranges and mounting arrangements; check the specification for the exact arm you intend to use.
The LX Desk Mount is a single-screen option for setups needing a stated adjustment range.
The M2.1 range is relevant to lighter single-monitor setups with a choice of mounting configurations.
The H1M1AG2 is a single-arm option with stated desk-clamp dimensions.
The Eppa range includes monitor arms with clamp and grommet mounting options.
Match the monitor’s VESA mounting pattern and weight without its original stand to the arm’s specifications. Check any stated screen-size limit too, but do not use diagonal size as the only test of compatibility.
Use a clamp if the desk thickness, edge and underside meet the mount’s installation requirements. A grommet mount needs a suitable desk hole and compatible hardware; a freestanding base avoids attaching to the desk but takes up worktop space.
No. An arm lets you adjust screen position, but the rest of the workstation still matters. The Health and Safety Executive advises placing the top of the screen at eye level and the display about an arm’s length away; check the keyboard, chair and glare as well.
The Health and Safety Executive says employers must assess workstations for workers who use display screen equipment daily as part of their normal work for continuous periods of an hour or more. The assessment covers the workstation, job and individual needs; purchasing a monitor arm does not replace it.
Check that the mount remains secure, the arm holds the monitor in position and cables have enough slack throughout the movement you use. Follow the manufacturer’s instructions for any tension adjustment and keep the monitor within the stated load range.
