The Ergotron LX Dual Stacking Arm will help you make a productive multi-display workspace as its flexible arms allows you to lift and move the screen wherever you want and get that precious worksurface on your desk. You can reposition your display with a simple touch and move your monitor up, down, forward or back.

The laptop mount also works well, and it can hold up to 25-inch laptops. The mount surface includes three choices to keep your portable computer in place, the non-slip rubber pad, Velcro and clips. The laptop mount however, can’t be brought down parallel to your desk’s surface because of the way the mount was designed. Your laptop has to sit at around 25° angle from the desk if you try to bring it all the way down. If you want your laptop to be parallel to your desk, then it has to sit around 5 inches above the desk.

Easy to Setup and Use

Like other Ergotron monitor stands, the LX Dual Stacking Arm is relatively easy to setup and mount to your desk. Right from opening the box, you can see the basic constructions of the whole setup. Also, the instructions lay out the step by step guide for hassle-free construction and installation.

Improved LX Arm for Optimum Durability

The LX Dual Stacking Arm is undeniably a well-built device that holds monitors up off the desk. Arms are perfectly balanced. You can do a laptop and a monitor or two monitors, whichever setup you want.

The middle arm can rotate 360° that can flip all the way around, and can move up and down about 90° to 180°. The base of the arm can also be moved 360°. The monitor can be pan up and down up to 75°, while the monitor itself can be moved left to right up to 180° and spin up to 360° in both arms without limit, which means easy change of orientation (portrait to landscape and vice versa). This means you have all the adjustments you need for a perfect and ergonomically friendly dual monitor configuration.

As far as adjusting the stiffness of the arms and how far to move both arms, Ergotron provide the allen wrench to adjust the tension of the arms. Also, the snap-fit cap secures better stability for interface of arms to extensions.

Solid Construction and Elegant Aesthetics

The polished aluminum construction offers both great durability and improved aesthetics. The bottom arm is incorporated with great cable management system to free your desk from cables and keep your workspace nice and neat. Both parts of the arm has this cable management system (zip tie for the top part of the arm) to completely keep your cables out of the way.

To facilitate stacking of the monitors, the maximum outside display height should not go beyond 14 inches. Most 24-inch displays or less can fit nicely with this specification. Larger displays are allowable when displays are positioned side by side.

The notebook holder has four (4) knobs for holding the laptop plate. Smaller knobs are used for holding the laptop plate, while the outer knobs are used for holding a monitor. At the front of the laptop plate are the metal bars that come in and out, which you can adjust in its bottom knob, depending on your laptop’s size.
