## Long description

The Ergotron LX Pro display arm expansion kit 98-734-290 for adding additional display to LX Pro arm is an accessory designed to extend an existing LX Pro monitor arm with the mechanical components and mounting interface needed to support an additional display. It is intended to integrate with the ERGOTRON LX Pro family to create dual or multi-monitor configurations, improving screen arrangement flexibility and enabling more efficient use of desk space in office and home workstations.
Advantages
This expansion kit provides a secure mechanical extension that matches the LX Pro system geometry and movement characteristics, preserving smooth articulation and stable positioning when an extra display is attached. By using components engineered for compatibility with the LX Pro family, the kit helps maintain the arm's load balance and range of motion while reducing the need for separate mounting hardware. The design supports adjustable tilt, pan and rotation through the existing LX Pro joints, allowing coordinated placement of multiple screens.
Suitable for
 Adding a second monitor to an existing LX Pro single-arm installation
 Converting a workstation to a dual- or multi-monitor setup
 IT and office environments requiring flexible screen arrangement
 Home offices where desk space optimization is needed
Key specifications
 Compatibility: designed for integration with the ERGOTRON LX Pro display arm family
 Function: mechanical extension and mounting interface for one additional display
 Mounting options: connects to existing LX Pro joints and mounting points
 Adjustment support: preserves tilt, pan and rotation functions offered by LX Pro arms
 Material and finish: metal components finished to match LX Pro appearance for consistent aesthetics
How to use
Install the expansion kit by first confirming the LX Pro arm model and current configuration. Follow the original LX Pro assembly sequence, attaching the expansion components to the designated extension point on the existing arm. Secure all fasteners to the recommended torque values and route any cables along the arm channels to maintain a tidy setup. After mechanical installation, adjust tension and screen alignment so the additional display moves smoothly and stays in the intended position during use.
Usage recommendations
Use the expansion kit only with compatible LX Pro arms and within the weight limits specified by the LX Pro documentation for multi-display setups.
