Monitor size is one exception: While the standard LX is rated for monitors up to 34 inches, the Side-by-Side’s arm is only rated for monitors up to 27 inches. The monitor arms aren’t long enough to fit two 32-inch or 34-inch monitors side-by-side. Vertical arrangements are also supported, though only if one of the two monitors is small (less than 23 inches diagonal). Surprisingly, the Flo has a listed weight limit of 20 pounds and recommends use with monitors weighing at least 7 pounds. Most monitors fit within this range, but some heavier models won’t be compatible with the Flo. To conclude, in my opinion, there’s one clear winner when it comes to comparing the best microphone boom arm stands – the RODE PS1. This is due to its all-round quality. Not only is it durable and sturdy, but it also has a full range of motion and has a classy design. Two monitors are always better than one, and the same goes for monitor arms. It’s no surprise, then, that Ergotron’s LX Side-by-Side ranks as our best dual monitor arm. The Ergotron LX Side-by-Side pairs two LX monitor arms together on one mount. The look, feel, and specifications of each arm are close to its standalone sibling.

Want a monitor arm that gets the job done and looks good doing it? The Herman Miller Flo is for you. The monitor’s range of adjustment isn’t much different from other high-end monitor arms. It offers 13.3 inches of vertical adjustment, 80 degrees of tilt, and 360 degrees of swivel and rotation. That’s essentially identical to the less expensive Ergotron LX. The Flo’s operation is smoother, however: I found I could adjust a monitor’s height with a mere nudge. Through its fusion of flexibility and strength, the M8 accommodates any single or dual monitor configuration weighing up to 18kg (40 lbs.). Unlike other high-capacity monitor arms with bulky designs, the M8 offers easy adjustment and flawless ergonomic function in an articulating monitor arm. Support for multiple monitor sizes: Because 27-inch monitors have become so common— they don’t cost much more than smaller displays—we considered only monitor arms that could handle a screen at least that size. All the models we tested can work with smaller displays, and a few can even hold larger displays, up to 34 inches. In today’s fast-paced, agile work environment, there’s no time for discomfort. M8.1, part of Humanscale’s revolutionary new monitor arm line, instantly improves the comfort, health and productivity of any workspace. Fully compatible with traditional desks and sit/stand workstations alike, M8.1 meets a variety of configuration needs for single monitors from 6 to 28 pounds or – with an optional crossbar support – dual monitors up to 12 pounds each.In today’s fast-paced, agile work environment, there’s no time for discomfort. M10, part of Humanscale’s revolutionary new monitor arm line, instantly improves the comfort, health and productivity of any workspace. Built to hold heavier equipment, it's optionalstrong triple crossbar allows M10 to hold up to three monitors or 48 pounds – all while maintaining a simple and sleek design.

M10, part of Humanscale’s revolutionary new monitor arm line, instantly improves the comfort, health and productivity of any workspace. Built to hold heavier equipment, it's optional strong triple crossbar allows M10 to hold up to three monitors or 21.8 kg (48 lbs.) – all while maintaining a simple and sleek design. Each arm is rated to hold between 4.4 and 14.3 pounds. That’s not a lot: The Workstream by Monoprice arm is rated up to 20 pounds. Still, it’s enough to handle a huge majority of 24- and 27-inch monitors, and the monitor arms provided plenty of lift in our testing. Featuring innovations like Humanscale’s patented Weight-Compensating Spring Technology and Smart Stop functionality, M2.1 enables the personalization and flexibility needed for today’s evolving workplaces.

We’re not a fan of the arm’s installation. It has two clamps instead of one unified clamp, which is strange, because the base of the monitor arm is one solid piece. There are roughly a dozen screws to install. And the included cable routing can prove hard to tighten once several cables are held within the routing. Grommet mounts insert into the circular cut-outs found on many desks built and sold for corporate offices. A grommet mount is also a form of clamp, but size of the mechanism is different, and the mount attaches the monitor to the interior of the desk instead of an exterior edge.Featuring innovations like Humanscale’s patented Weight-Compensating Spring Technology and Smart Stop functionality, M10 enables the personalization and flexibility needed for today’s evolving workplaces.

In many ways, a keyboard support is the heart of an ergonomic workstation. As reach and vision drive posture, our keyboard tray allows the user to sit in a healthy, neutral posture through bringing the keyboard and mouse to the user in an ergonomic position. First, let’s talk weight. The Ergotron HX is rated to hold monitors that weigh up to 42 pounds and screen sizes up to 49 inches. That’s an extraordinarily high weight limit—I haven’t reviewed a single monitor in 2023 that exceeds it. I attached both a 32-inch widescreen and 38-inch ultrawide monitor, which weighed roughly 15 and 20 pounds, respectively, and the HX easily handled both. The Workstream by Monoprice single monitor arm is a no-frills solution that delivers basic monitor arm features at an exceptionally low price.

The monitor arm has an all-metal construction that in some ways feels sturdier than the Ergotron LX, as the Workstream doesn’t include as much plastic cladding. It’s not entirely a win, though, as the plastic that exists feels frail (and I even broke a small, though unnoticeable, bit while adjusting the monitor). The Huanuo HNDS12, like the HNDS6 (below), is a bit fiddly to set up. It has two clamps that need to be adjusted and roughly a dozen screws that need to be installed. The gas springs also require a bit of adjustment to reduce the force provide, at least when used with a 24-inch or 27-inch monitor. In today’s fast-paced, agile work environment, there’s no time for discomfort. M2.1, part of Humanscale’s revolutionary new monitor arm line, instantly improves the comfort, health and productivity of any workspace. Fully compatible with traditional desks and sit/stand workstations alike, M2.1 meets a variety of configuration needs for lighter monitors up to 15.5 lbs.

Featuring innovations like Humanscale’s patented Weight-Compensating Spring Technology and Smart Stop functionality, M8.1 enables the personalization and flexibility needed for today’s evolving workplaces. The Huanuo HNDS12 represents a middle ground for shoppers who want an upgrade in quality but need to respect their budget. Setup is simple. The monitor has an included clamp and grommet mount. Installation is mostly handled with a bundled Allen wrench, though you’ll still need a Philips head screwdriver to attach your monitor to the VESA mount. Most owners will be able to install smaller monitors (24 to 27 inches) alone, but help is recommended for larger displays.
