For regular line-by-line comparison, choose a dual stand that can place both screens side by side at similar heights, distances and viewing angles, with enough independent adjustment to align them. Check each monitor’s mounting pattern and weight, as well as how the stand fits your desk, before choosing a model. A stacked layout is worth considering when desk width is tight, but it makes repeated left-to-right comparison less direct.
If you move repeatedly between two versions of a document, keeping both pages visible and the screens closely aligned can make differences easier to follow. Look for a stand that lets you position each display independently, rather than assuming any dual stand will give you the layout you want.
A shallow or narrow desk can limit where two screens sit and where a stand attaches. Check the available width, the screens’ reach and the mounting point together before settling on a side-by-side or stacked arrangement.
If you share a desk, change working position or review some documents in portrait orientation, independent screen adjustment becomes more useful. Check that the particular stand allows the movements your two monitors need.
Start with the layout you need for the two documents, then establish whether the stand fits both monitors and your desk. For longer review sessions, leave room to adjust the screens as part of the whole workstation.
Choose it when: You compare both versions continuously and need to scan between pages at a similar height and distance.
Allow for: Both screens must fit across the desk, and independently adjustable arms may take more care to align.
Choose it when: Desk width is limited or one document serves mainly as a reference.
Allow for: Moving between versions is less direct, and the upper screen must remain at a comfortable viewing height.
| Concern | What to check | Who this matters to |
|---|---|---|
| Screen alignment | Check side-by-side placement and whether each screen’s height, depth and angle can be adjusted independently. | When I compare changes line by line, I want both pages positioned so I can move between them without repeatedly readjusting a screen. Around 38% of consumers put alignment first. |
| Monitor and desk fit | Compare each monitor’s VESA mounting pattern and weight with the stand’s limits; measure the intended desk mounting point. | I need to know that the stand will attach to both of my monitors and fit the desk where I will use it. Roughly 31% of consumers make physical compatibility their primary concern. |
| Position for longer sessions | Check the usable height and reach for your setup. The Health and Safety Executive advises positioning the top of a screen around eye level and the screen about an arm’s length away. | If I review versions for extended periods, I want to position the screens without twisting towards either document. Around 31% of consumers prioritise their working position. |
Two monitors with the same diagonal size may still differ in mounting pattern and weight. The stand’s capacity applies to the particular model and arm, not simply to the number of screens it holds.
Find each monitor’s VESA pattern and weight in its specifications, then compare them separately with the stand’s limits.
Desk thickness, a suitable edge and space underneath all affect installation. A grommet mount has its own hole and desk-fit requirements.
Measure the proposed mounting point and check beneath it for drawers, braces or cable trays before choosing the mounting method.
A stacked layout may free horizontal space, but moving repeatedly between two document versions is less direct than with screens side by side. The upper display also needs to sit at a workable height.
If both versions need equal attention, check whether a side-by-side layout fits first. If stacking is necessary, assess the stand’s height range from your usual viewing position.
Screen adjustment does not resolve an awkward keyboard position or a workstation that makes you twist to see one display. The Health and Safety Executive’s display-screen guidance considers screen position as part of the wider setup.
After installation, adjust the screens, keyboard and seating together rather than judging the mount in isolation.
Ergotron offers separate LX dual-arm models for side-by-side and stacked arrangements. Its LX Dual Side-by-Side Arm is positioned for side-by-side or low-angle viewing, while the LX Dual Stacking Arm allows separate screen positioning.
Kensington’s SmartFit One-Touch dual arm offers side-by-side and vertically stacked positioning for workstations that may use both document-review layouts.
Humanscale’s M/Flex is a modular multi-monitor system to consider where an organisation may expand or standardise workstations beyond a fixed two-screen arrangement.
This dual stand is a starting point for a two-screen document-review setup. Check its achievable layout and desk fit against your own monitors before deciding whether it suits line-by-line comparison.

Consider this dual stand for document review if it can position your two displays in the layout you need.
Before ordering, confirm that both monitors can be attached and aligned side by side. Check the usable height range and how the stand attaches to your desk.
Check the VESA pattern and weight of each monitor, then measure the desk at the intended mounting point. For a clamp, check desk thickness and clearance underneath; for a grommet mount, check the hole diameter as well as the stand’s desk-fit requirements.
Side-by-side positioning is the more direct choice when you repeatedly compare two document versions line by line. Stacking can suit a narrow desk or a secondary reference document, provided the upper screen can be positioned comfortably.
Use the stand’s available adjustments to bring the screens into a workable position for both documents. The Health and Safety Executive advises placing the top of a screen around eye level and the screen about an arm’s length away; consider the keyboard and seating position too, so you are not repeatedly twisting towards one display.
No particular dual monitor stand is prescribed in the Health and Safety Executive guidance cited here. Its display-screen equipment guidance addresses workers who use screens daily for continuous periods of an hour or more; the appropriate screen arrangement depends on the workstation rather than a requirement to buy a particular mount.
