Multitasking in a modern work environment can present multiple problems if you’re working from a small desk surface. Fitting two large monitors side-by-side generally requires two large sections of your desk to hold monitor stands, taking up precious workspace. The Ergotron LX Dual Side-by-Side Arm is designed to solve this problem, elevating two monitors next to each other, while only needing a very small footprint on your desk to mount the stand.

The new Ergotron LX-series monitor and accessory stands keep a similar design to the old models while updating the line with a much cleaner polished metal finish. The older design used a metallic silver paint over the cast metal segments. The new design shows off the cast metal segments after being thoroughly polished and then covered with a clear coat of paint designed to seal and protect the finish. The design is used in all LX-series stands which are offered in numerous configurations. While our review unit is aimed at holding two monitors side by side, they also offer models to hold monitors with accessories (including notebooks), keyboard mounts, single monitor mounts and wall mounts.

The Ergotron LX Side-by-Side Arm is designed to attach to the top surface of a desk – it clamps over an edge, bolting through a pre-drilled wire hole or through a small self-drilled hole. For our review we attached the stand to the surface of our desk from the side, so as not to have any visible holes in the top surface when the review was completed. The stand is designed for compatibility with desks where the top floats on brackets – like what you might find in a cubicle environment – since it needs to completely wrap around the edge to the lower brace. The desk used in our review is a user-assembled desk where the back panels are secured flush to the top surface. This required some minor work with a reciprocating saw to make an opening through the back panel. For more permanent mounting options, drilling a small hole through the top of the desk surface would be preferred.

Assembly was very simple as the majority of the components slip together in the form of pre-made sections. Each arm segment is completed in the box; there’s only minor “set-screw” tightening required to hold the parts together. Ergotron also includes finishing caps that go on the top of the hinge points to close off the top of the pipe segments. These caps pop into place with tension clips. While the Ergotron LX is clearly bristling with industrial design, elements such as the finishing caps go a long way toward adding finish and polish to the final product. Not counting the time to cut a notch in the back of our desk – which shouldn’t apply to normal users-the entire assembly process took about 15 minutes from start to finish.

In Use
The controls and movement of the Ergotron LX Side-by-Side are very intuitive. The stand has multiple pivoting points which allow you to angle monitors right where you need them, elevating them off your desk. The height that to which monitors can be lifted varies depending on the screen size, but with a 20-inch display, it was about eight inches. To allow monitors to float – that is, to hover comfortably in the above the desk – the stand has a spring with adjustable tension so devices have neutral buoyancy and don’t sag or slowly lift once their position has been set. The stand has a minimum weight of five pounds per arm, with a maximum weight of twenty pounds. On the upper end we were able to adequately support a 27-inch LCD on arm – and a full-on all-in-one desktop on the other – with some tension spring adjustment.

The new stand now offers some cable management options. One arm section completely conceals the wires through its length, while the lifting arm uses wire ties to hold wires onto the bottom of it. Compared to the previous cable management this addition is welcome, although I do kind of prefer that the wires were hidden in both sections. The wire management keeps the entire workspace as cleanly-designed as the Ergotron itself, even with power, video, data and sound cables running every which way.

The Ergotron LX Side-by-Side Arm is a very sturdy and very well-built monitor stand. While the stand does run on the expensive side-priced at $329-you easily get what you pay for in this situation. The stand is built upon a sturdy metal design with a polished finish and high quality components. The stand can easily hold most monitors, including a 27-inch LCD, and still control height adjustments. Compared to the previous generation LX-monitor stand, the new design brings better looks and a greater attention to detail, something we really enjoy seeing on next-generation products. If you need a sturdy monitor stand that can hold up to the rigors of day-to-day commercial use, look no further than the Ergotron LX series of monitor stands.
