Dual monitor stand: which arm to choose depending on your monitors?
A dual monitor stand allows you to attach two monitors to a single articulated arm or two independent arms, freeing up floor and desk space. Before buying, three parameters must be checked without exception: VESA compatibility of the monitors, maximum load per arm, and the spacing between the two monitors once mounted.
The VESA standard is indicated on the back of the monitor or in the PDF manual. The most common values are 75 × 75 mm and 100 × 100 mm. An arm whose VESA plate does not match the monitor's mounting holes cannot be used — no adapter compensates for a standard incompatibility.
The actual weight of each monitor is available on the manufacturer's technical data sheet. Do not use estimates: a 27-inch screen can weigh from 4.5 kg to 7.5 kg depending on the panel and chassis. JAPANNEXT indicates verifiable technical data on each product sheet, with warranty and return conditions clearly detailed. This guide covers the criteria to know for choosing a suitable stand for your setup.
Dual arm or two single arms: what's the concrete difference?
A dual monitor articulated arm rests on a single mounting column with two arms extending from a single central pivot. Two independent arms use two distinct fastenings — two clamps or two screwed plates — which doubles the footprint under the desk and multiplies the adjustment points.
The concrete difference concerns two aspects. First, height adjustment: on a dual arm, both monitors share the same column height. Horizontal alignment is easy to achieve, but the individual adjustment range is reduced. With two single arms, each monitor is independently adjustable in height and tilt.
Second, load. A 2-monitor stand on a single column concentrates the total weight on a single attachment point. For two 27-inch monitors weighing 5 to 7 kg each, the column must absorb 10 to 14 kg. Ensure that the clamp or plate is sized for this total load, not just for the weight of one screen.
Technical criteria to check before buying (VESA, load, spacing)
Three criteria are crucial for any dual monitor arm.
VESA compatibility. The VESA standard defines the spacing of the screw holes on the back of the monitor. Values of 75 × 75 mm and 100 × 100 mm cover almost all monitors up to 32 inches. Some large formats use 200 × 200 mm. To check: turn the screen over or search for "VESA" in the technical data sheet on the manufacturer's website. The 75 × 75 mm and 100 × 100 mm standards are interchangeable on most arms via an included adapter plate.
Maximum load per arm. The best monitor arm for 27 inches should support a minimum of 7 to 8 kg per arm to cover the heaviest models. For 32 inches, plan for 10 to 12 kg per arm. The actual weight of the monitor is indicated on the manufacturer's data sheet — the value to use is the weight without the base.
Spacing between monitors. The spacing depends on the articulated arm's range of motion: horizontal rotation relative to the column, and distance between the two pivots. For an articulated monitor arm for 27 inches in a side-by-side configuration, a horizontal rotation of at least 90° per arm allows for aligning both monitors facing the user without any disturbing residual angle.
The JN-A-G210A2C (JAPANNEXT) accepts VESA 75 × 75 mm and 100 × 100 mm standards, with a maximum load of 8 kg per arm and a 180° horizontal rotation.
Desk stand or wall mount: how to choose based on your setup?
A wall-mounted monitor stand fixes the arms directly into the partition or concrete via a screwed plate. This type of mounting is suitable for setups without an accessible desk edge, or for desks whose top is too thin or too light to withstand a clamp.
A wall-mounted dual monitor stand completely frees up desk space. In return, the position of the monitors is defined by the wall mounting point, which is permanent. The wall's resistance must be checked: concrete and brick support without difficulty; a plasterboard requires specific anchors whose admissible load must cover the total weight (arm + monitors).
A wall-mounted articulated monitor arm generally requires a 100 × 100 mm or 200 × 200 mm plate depending on the weight of the screens. The admissible loads are indicated by the arm manufacturer — not by the anchor manufacturer.
Clamp mounting (desk clamp) is suitable for desks with a thickness between 10 and 80 mm depending on the model. Check the actual thickness of the top and the material: light particle board deforms under load; a solid or steel top is more reliable.
Compatible screen sizes: 24, 27, and 32 inches in dual configuration
Dual arms generally cover diagonals from 13 to 32 inches. The three most common configurations:
24-inch dual monitor stand. Usual weight: 3 to 5 kg per screen. VESA compatibility 75 × 75 mm or 100 × 100 mm depending on the manufacturer. Load per arm is generally not a limiting factor for this diagonal.
27-inch dual monitor stand. Usual weight: 4.5 to 7.5 kg per screen. VESA compatibility mainly 100 × 100 mm. An articulated monitor arm for 27 inches must support at least 8 kg per arm to cover the heaviest models.
32-inch dual monitor stand and 32-inch dual monitor stand. Usual weight: 7 to 12 kg per screen depending on the panel (IPS, VA, OLED) and the chassis. Check the load limit per arm individually — some dual arms are limited to 8 kg, insufficient for the heaviest 32-inch models.
A vertical dual monitor stand (portrait orientation) is possible if the arm allows for 90° rotation. Check the rotation range in the technical data sheet. On a vertical dual monitor stand, the VESA axis remains identical but the panel orientation changes — the screen's weight does not vary, and the load per arm remains the same.
Installation and adjustments: what you need to know before mounting
Installation follows four steps, whether for a desk stand or a vertical dual monitor stand in a wall-mounted configuration:
1. Attach the screw-on plate or clamp to the edge of the desk (or the wall plate depending on the chosen mounting). Tool required: Allen key provided, flat-head screwdriver if the clamp is manually tightened. Estimated time: 5 to 10 minutes.
2. Assemble the column and the two arms according to the manufacturer's instructions. Tool required: Allen key. Estimated time: 5 to 10 minutes.
3. Screw the VESA plates to the back of each monitor — screws are usually included in two sizes to cover 75 × 75 mm and 100 × 100 mm. Tool required: Phillips screwdriver. Estimated time: 3 to 5 minutes per screen.
4. Hang the monitors on the arms and adjust the friction tension of each pivot. No tools for hanging; Allen key for friction adjustment. Estimated time: 5 minutes.
Reference configuration: two 27-inch monitors side-by-side on a straight desk. The number of parts to assemble is 8 to 14 elements depending on the model. Total installation time: 25 to 45 minutes depending on the type of mounting and experience.
After installation, height adjustment is done by loosening the column lock. Individual screen rotation is adjusted via the pivot's friction screw.
Cable management. An arm with an integrated cable channel allows HDMI and DisplayPort cables to pass inside the structure — plan for a cable length of 1.5 to 2 m depending on the distance between the PC and the monitors, and insert the cables into the channel before hanging the monitors. An arm without a cable channel requires cable ties (zip ties) to group the cables along the column and prevent them from hindering articulated movements. Cable finishing time: 10 to 15 minutes with integrated channel, 20 to 30 minutes without channel.
FAQ — Dual Monitor Stand
Which dual monitor stand to choose?
The choice depends on three parameters: the VESA standard of the monitors (75 × 75 mm or 100 × 100 mm), the weight of each monitor (to be checked on the manufacturer's data sheet), and the type of mounting available on the desk (clamp or wall plate). For two 27-inch monitors with VESA 100 × 100 mm and 5 to 7 kg each, a dual arm like JapanNext's JN-A-G210A2C meets the criteria.
How to set up a dual monitor on your computer?
Connect two monitors to the computer via the available outputs (HDMI, DisplayPort, USB-C). In Windows: Settings > Display > Detect, then choose "Extend these displays" for an extended desktop configuration. The vertical or horizontal dual monitor stand is independent of the software configuration — the operating system manages the display orientation.
Which articulated arm for a monitor?
A monitor articulated arm must match the maximum load (≥ weight of the monitor without its base), VESA compatibility, and the type of desk mounting. For most 24 to 27-inch monitors, an arm supporting 8 kg per arm covers common configurations.
How to choose a monitor arm?
Four criteria: VESA compatibility (75 × 75 or 100 × 100 mm), maximum load per arm (greater than the weight of the screen without its base), articulated range (horizontal rotation, tilt, height adjustment in mm), type of mounting (clamp or wall plate depending on the desk).
Which wall mount for a monitor?
A wall-mounted articulated monitor arm must match the monitor's VESA standard and its weight. The wall mounting must be sized according to the total weight of the arm + monitor. Check the strength of the wall mount: concrete and brick support without problems; plasterboard with an appropriate anchor according to the load indicated by the anchor manufacturer.
