Overview

The Ergotron LX Desk Monitor Arm (model 45-241-026) is a long-standing favorite in the single-monitor arm category, trusted by offices and creative professionals worldwide. It supports monitors up to 11.3kg and fits screens from 13 to 34 inches. The patented Constant Force (CF) technology enables effortless height adjustment regardless of monitor weight — once set, you can reposition the screen with a single finger. Two mounting options are included: a desk clamp and a grommet mount, accommodating desk edges up to 75mm thick. Built-in cable management routes wires through the arm, keeping your workspace tidy.

Connectivity & Compatibility

The arm supports VESA patterns 75×75mm and 100×100mm, covering the vast majority of modern monitors. Maximum reach is approximately 59cm, allowing you to pull the monitor close or swing it to the side for flexible positioning. For clamp mounting, the desk edge must be between 10mm and 75mm thick and relatively flat. For grommet mounting, a hole diameter of 10–50mm is required.

Product Info

Ergotron LX has been in production since the early 2000s and continues to receive incremental improvements. In Japan, the retail price typically ranges from ¥15,000 to ¥20,000, placing it in the mid-range segment for monitor arms. The manufacturer offers an industry-leading 10-year warranty, making it a reliable choice for both home and business use. Included in the box: clamp, grommet mount, cable clips, and hex key. Assembly is straightforward with the provided tool.

Best Use Cases

First, office workers who want to reclaim desk space will benefit greatly. Lifting the monitor off the surface frees up room for documents, a laptop, or other peripherals, improving workflow efficiency. Second, users planning a dual-monitor setup can pair two LX arms for independent left/right positioning. This gives you precise control over each screen’s angle and height. Finally, creative professionals and programmers who frequently change their viewing posture will appreciate the smooth CF height adjustment. Whether you stand or sit, the arm adapts instantly without needing to loosen any knobs.
