Product Overview
The Ergotron 45-496-216 MXV Desk Dual Monitor Arm is a white desk-mounted monitor support system designed for two compatible LCD displays arranged side by side. Its streamlined V-shaped design provides adjustable screen positioning while keeping the mounting structure compact and organized.
Part of Ergotron's MXV monitor arm series, this model uses Constant Force motion technology to make display repositioning easier. The dual-arm configuration supports independent adjustment of each monitor, helping users arrange their screens for different workstation tasks.
Display Positioning and Adjustability
The MXV dual monitor arm provides integrated height adjustment, articulated movement, and screen rotation. Monitors can be repositioned horizontally, tilted for a suitable viewing angle, or rotated between landscape and portrait orientations.
- Height adjustment: Up to 13 inches (33 cm).
- Tilt: Up to 180 degrees of total forward and backward movement.
- Pan: Up to 360 degrees of movement, depending on the joint and installation configuration.
- Screen rotation: 360 degrees for landscape or portrait positioning.
- Extension: The arms extend to provide flexible monitor positioning and can fold back toward the base when not required.
Monitor Compatibility
This mounting system supports two compatible LCD monitors, each weighing between 7 and 20 lb (3.2–9.1 kg), with a maximum combined display weight of 40 lb (18.1 kg). Displays up to 24 inches are the recommended size for normal adjustment capability; larger screens may be accommodated with reduced adjustment depending on their dimensions and configuration.
The arm supports VESA MIS-D mounting patterns of 75 x 75 mm and 100 x 100 mm. Confirm the mounting pattern, weight, depth, and physical dimensions of both monitors before installation.
Desk Installation
The included two-piece desk clamp attaches to a compatible desk edge measuring 0.47–1.25 inches (12–32 mm) thick. Anti-rotation screws help prevent the base from slipping during normal adjustment.
A separate grommet mounting accessory, part number 98-111, is available for compatible through-desk installations. This accessory is not part of the standard desk-clamp configuration.
Cable Management and Design
Integrated cable management routes monitor cables beneath the arms, helping keep the desk surface organized. The slim design occupies less visual space than the LX arm profile and supports a clean dual-screen workstation arrangement.
Key Features
- Dual-monitor support for two compatible displays arranged side by side.
- Constant Force motion technology for convenient display repositioning.
- 13 inches (33 cm) of integrated height adjustment.
- 360-degree screen rotation and adjustable tilt for flexible viewing orientations.
- Integrated cable management and a compact desk-clamp mounting design.
Applications
The MXV dual monitor arm is suitable for office desks, home workstations, administrative environments, programming setups, and other work areas that use two displays simultaneously. Its adjustable arms allow users to position applications, documents, and reference material across separate screens.
DC Supplies Product Note
Check each monitor's weight separately before installation. Both displays must fall within the supported 7–20 lb range, and their combined weight must not exceed 40 lb. Also verify desk thickness and available clearance, especially when positioning larger displays side by side or rotating them into portrait orientation.
