Build a Multi-Monitor Workstation
The expansion kit attaches to a compatible LX Pro pole or the LX Pro Dual Side-by-Side Collar accessory. It can help create configurations for two, three, or four displays when combined with the appropriate compatible LX Pro components.
For monitors positioned alongside one another, the compatible Dual Side-by-Side Collar is required. Stacked multi-monitor arrangements require the appropriate tall-pole configuration and LX Pro Large Base. Additional collars and expansion kits may be needed depending on the number and arrangement of displays.
Monitor Compatibility
This kit supports displays weighing between 4 and 22 lb (1.8–10 kg) and measuring up to 34 inches, subject to mounting compatibility. It uses a VESA MIS-D interface with 75 x 75 mm or 100 x 100 mm mounting patterns.
Display dimensions, depth, weight, and VESA mounting pattern can affect compatibility. Check your monitor specifications and the requirements of the complete LX Pro configuration before installation.
Cable Management and Adjustment
The integrated cable-management system routes cords beneath the arm to reduce clutter. The arm offers adjustable height, tilt, pan, and rotation to help position a compatible display for comfortable viewing.
DC Supplies Product Note
This product is an LX Pro monitor arm expansion kit, not a complete desk or wall mounting base. Confirm that your existing mounting system belongs to the LX Pro family; LX Pro components are not interchangeable with the legacy LX product line. For multi-monitor installations, verify that the base, pole, collars, and expansion components match the intended configuration.
