Overview

The Ergotron LX Single Monitor Arm is a gas-spring monitor arm designed for users who want to freely position their display on a desk. It supports monitors up to about 11.3 kg and offers smooth height adjustment, tilt, pan, and rotation. Two mounting options—clamp and grommet—are included, fitting most desks. This product is ideal for anyone looking to build an ergonomic workspace. By aligning the monitor at eye level, you can reduce strain on your neck and shoulders. It also frees up desk space, giving you room for documents or peripherals.

Connectivity & Compatibility

The arm supports clamp mounting (up to 75mm desk thickness) and grommet mounting (up to 55mm). It is compatible with VESA 75x75mm and 100x100mm patterns, covering the vast majority of monitors on the market. Built-in cable management clips keep wires tidy along the arm.

Product Info

The Ergotron LX Single Monitor Arm has been a long-selling mid-to-high-end monitor arm since its 2007 launch. Pricing is around ¥15,000–¥20,000 in Japan and $150–$200 globally. It comes with a 10-year warranty, reflecting its durable build. Included accessories: clamp, grommet mount, cable clips, and hex key. In the market, the LX is considered the standard for gas-spring arms. It is also the basis for the Basics monitor arm (an OEM version). While priced higher than budget alternatives, its build quality and warranty support make it a favorite among professionals.

Best Use Cases

Remote workers and home-office users: Perfect for maintaining good posture during long work hours. Adjusting the monitor to eye level reduces neck and shoulder fatigue. Multi-monitor setups: You can combine multiple LX arms for a flexible multi-display configuration. Each arm moves independently, allowing custom arrangements. * Space-conscious users: Removing the monitor stand frees up significant desk area for documents, laptops, or other gear. If you are on a tight budget or rarely move your monitor after setup, a fixed arm or cheaper gas-spring model may suffice.

Things to Consider

Check your desk thickness before purchase: clamp mount supports up to 75mm, grommet mount up to 55mm. If your monitor exceeds 11.3 kg, consider the heavier-duty Ergotron HD series. Gas springs can lose tension over years of use, but Ergotron's 10-year warranty provides peace of mind. Note that parallel-imported units may not be covered by warranty, so buying from an authorized dealer is recommended. Competitors include the Basics monitor arm (essentially the same design at roughly half the price) and budget brands like Huanuo. The Basics version offers better value but has a shorter warranty and occasional quality inconsistencies. The Ergotron LX is the safer choice for those prioritizing consistent quality and long-term support.
