Premium stacked dual monitor arm with Constant Force technology for professional setups

Ergotron LX Dual Stacking Arm: The professional standard for stacked monitor configurations

At $150, the Ergotron LX Dual Stacking Arm is the reference product for vertical dual monitor setups. Constant Force technology, a 40 lb weight capacity per arm, and Ergotron's build quality distinguish it from cheaper alternatives that physically move under the same description. For developers and financial professionals who use a stacked primary/secondary monitor layout, this is the appropriate tool.

What works

Constant Force technology is Ergotron's mechanism for maintaining monitor position. Unlike budget arms that drift over time as friction wears, Constant Force uses a spring-loaded system calibrated to the monitor weight. Once positioned, the monitor stays. If you come back after a weekend and your monitor has crept down — a common complaint with cheaper arms — Ergotron's mechanism eliminates that.

40 lbs per arm accommodates large professional displays including some 4K professional monitors that cheaper arms can't support. The 32-inch maximum screen size covers the current generation of professional displays.

Ergotron builds monitors arms that last. The LX series has been in production for years with consistent quality. The warranty is genuine and the customer service is accessible.

What doesn't

At $150, it's the most expensive standard dual arm in this comparison. The stacked configuration is specifically designed for one monitor above another — for side-by-side setups, the standard Ergotron LX Dual Side-by-Side is the appropriate product. This one is specifically for stacking.

Who should buy this

Developers, financial analysts, and professionals who use a stacked monitor configuration for primary work and secondary reference content. If you've had cheaper arms drift or fail, the Ergotron LX ends that cycle.

Who should look elsewhere

Side-by-side layout: Ergotron LX Dual Side-by-Side, HUANUO ($50), or Fully Jarvis ($200). Budget gas spring: EleTab ($55) or HUANUO ($50). Non-gas-spring minimum: Amazon Basics ($50).
