For two document versions viewed side by side, consider a crossbar stand if keeping the screens level is your priority, or independently adjustable arms if you regularly change either screen’s position. Before choosing, check each monitor’s weight and mounting pattern against the stand’s limits, then make sure its base or desk fixing suits your workspace.
If both versions stay open for visual checking, a level, closely spaced layout may matter more than frequent repositioning. StarTech.com describes its freestanding crossbar stand as keeping two monitors horizontally aligned.
If you change the angle or distance of a reference screen during the day, independently adjustable arms give you a different arrangement from a crossbar. Check that the chosen arm fits your desk as well as your monitors.
Start with each display’s weight and mounting pattern rather than its diagonal size alone. The limits differ between the Ergotron, StarTech.com and Dataflex models described below, so check the exact model and variant before ordering.
Decide whether the two document screens need a repeatable level layout or more independent movement, then check the monitors and desk against the mount you prefer.
| Concern | Buying check | Who this matters to |
|---|---|---|
| Side-by-side alignment | Check that the mount can place both screens level and close enough for your document layout. A crossbar may simplify repeatable alignment. | I want to scan between two versions without repeatedly adjusting their height; around 42% of consumers would put alignment first. |
| Desk fit and adjustment | Measure the usable desk edge and look for obstructions beneath it. Check which independent screen movements the chosen model provides. | When I need to bring a reference screen closer or change its angle, the fixing must also work on my desk; adjustment and desk fit would be the main concern for around 33% of consumers. |
| Monitor compatibility | Compare each display’s weight and mounting-hole pattern with the stand’s per-screen limits; check any model-specific depth restrictions. | If my displays are heavy or have different mounts, I need to know that both can attach within their individual limits. Around 25% of consumers would prioritise monitor compatibility. |
Two stands advertised for displays of the same diagonal can have different per-screen weight limits. StarTech.com specifies 6 kg per display for its 2MC1S-MONITOR-STAND, while Ergotron specifies a 3.2–9.1 kg range per display for its LX Dual Side-by-Side Arm.
Check each monitor’s weight without its original stand, its mounting pattern and any applicable depth limit against the exact mount.
Desk-edge thickness and fittings beneath the worktop can prevent a clamp from seating properly, even when the arm supports both monitors.
Measure the clear edge and inspect underneath before ordering. If the desk cannot accommodate the fixing, consider a freestanding base and account for the surface it occupies.
A crossbar can maintain a level pair of document screens, but it may not offer the independent reach needed to bring one display closer.
Choose the layout around how often you move each screen: check crossbar adjustment for a mostly fixed pair, or individual arm movement for a changing arrangement.
Screen position is only part of a workstation arrangement. The UK Health and Safety Executive advises placing the top of a screen around eye level and the display about an arm’s length away.
After installation, adjust the screens in relation to your chair, keyboard and lighting, and review the complete workstation.
The LX Dual Side-by-Side Arm is an articulated option for individually positioning two monitors.
The DM252 is a clamp-mounted dual arm for users who want to adjust two office monitors.
The 2MC1S-MONITOR-STAND is a freestanding crossbar option for a level, side-by-side layout.
The Viewmate dual-monitor arm is a horizontally aligned option with independent positioning.
Dell’s MDA20 dual arm is an option to examine for compatible Dell displays.
This dual-monitor stand is a choice to examine if you want to reposition screens while comparing documents. Check whether it can also hold your preferred side-by-side layout.

Consider this stand if you need to change screen positions during document comparison. Before ordering, check whether its adjustment range keeps both screens level, and confirm each monitor’s weight and mounting pattern as well as the stand’s desk fitting.
Keep the pair where you can read both without sustained twisting; for two equally used screens, placing their join near your central viewing line is a practical starting point. The UK Health and Safety Executive advises positioning the top of a screen around eye level and the display about an arm’s length away, then adjusting the arrangement to your workstation.
Both monitors need a mounting arrangement compatible with the particular stand. The Ergotron, StarTech.com and Dataflex examples described here specify VESA 75 × 75 mm or 100 × 100 mm patterns; if a display lacks a supported pattern, use an adapter only after confirming compatibility with that monitor and the stand’s load limit.
Measure the clear desk-edge thickness and check beneath the worktop for anything that would obstruct the clamp. Manufacturer specifications differ: Ergotron lists an edge limit of up to 66 mm for its LX Dual Side-by-Side Arm, while Duronic lists 10–88 mm for the DM252.
No. For workstations covered by UK display-screen-equipment requirements, the Health and Safety Executive says employers must assess the workstation and reduce risks. The stand is one part of the arrangement, not a substitute for reviewing the complete workstation.
