The Ergotron LX Pro Desk Monitor Arm (45-712-292) is an adjustable desk-mounted monitor support designed to improve viewing comfort while freeing up valuable desktop space. Its articulated arm allows users to raise, lower, tilt, pan, and rotate a compatible display to suit their workstation.
Finished in matte black, this LX Pro model features a low-profile C-clamp, integrated cable management, and Ergotron's Constant Force movement technology. Its modular design and straightforward mounting system make it suitable for office and home-office environments.
Key Features
- Single-monitor support: Holds one compatible display weighing 1.8–10 kg (4–22 lb).
- Ergonomic adjustment: Provides up to 33 cm (13 inches) of lift for flexible screen positioning.
- Low-profile C-clamp: Attaches to a compatible desk edge without requiring a grommet mounting hole.
- Flexible screen movement: Supports tilt, pan, and 360-degree monitor rotation.
- Integrated cable management: Helps route cables neatly along the arm to reduce clutter and prevent snags during movement.
Monitor Compatibility and Adjustment
The LX Pro Desk Monitor Arm is designed for one monitor with a recommended screen size of up to 34 inches and a supported weight range of 1.8–10 kg (4–22 lb). Screen size is a guideline; compatibility also depends on display weight, depth, dimensions, and mounting pattern.
The arm provides up to 33 cm (13 inches) of lift and extends up to approximately 64 cm (25 inches). Its adjustment capabilities allow the display to be moved closer to the user, repositioned horizontally, tilted, or rotated between landscape and portrait orientations.
Desk Mounting and Installation
This version uses a low-profile C-clamp designed for desk edges approximately 12–40 mm (0.47–1.57 inches) thick. The area beneath the desk must provide sufficient clearance for the clamp and mounting hardware.
Before installation, check the desk's thickness, construction, edge shape, and underside clearance. The mounting surface must be suitable for supporting the arm and display securely.
VESA Compatibility
The monitor pivot supports VESA MIS-D mounting patterns of 75 × 75 mm and 100 × 100 mm. Verify the mounting-hole pattern on the monitor before ordering. Displays with greater depth may affect the arm's supported weight capacity.
Movement Control and Cable Management
Ergotron's Constant Force technology enables smooth positioning when the arm is correctly adjusted for the installed display. A tension-level indicator provides a visual reference during adjustment, helping users set the arm's counterbalance appropriately.
An integrated rotation stop can restrict side-to-side movement at the extension joint to help prevent the arm from contacting nearby walls or partitions. Cable-routing features help keep monitor connections organized as the display moves.
Typical Applications
- Office and home-office workstations
- Single-monitor desktop setups
- Professional productivity environments
- Workstations requiring adjustable screen positioning
- Desks where preserving usable surface space is important
DC Supplies Product Note
Before ordering, confirm that the monitor weighs between 1.8 and 10 kg (4–22 lb), uses a supported VESA pattern, and fits the intended desk configuration. Check that the desk edge is 12–40 mm thick and that sufficient clearance is available underneath for the C-clamp. Allow adequate cable slack throughout the arm's movement range.
