It’s natural, given the only slight difference in name, to think the Ergotron HX is merely an uprated version of the Ergotron LX. That’s not the case. This is an entirely different monitor arm which pairs its increased capacity with improved build quality and a more professional look.

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 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. 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.

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.

Each monitor arm is almost all metal with only a small piece of plastic to provide cable routing. The arm also has gas springs capable of lifting up to 26 pounds of weight, which is enough to handle 32-inch widescreen and 34-inch ultrawide monitors. It provides a good range of adjustment, with 13.2 inches of height and 90 degrees of tilt, swivel, and rotation. The arm’s height and tilt adjustment are comparable to others on this list, but it can’t swivel in a full circle, which may prove annoying if you frequently move a monitor arm to share your screen with colleagues. Monoprice lists the monitor as capable of supporting 20 pounds, but I felt the 32-inch monitor (which weighed 15 pounds) was pushing the Workstream to its limits. Monoprice also skimps on the warranty, offering just one year of coverage. A standout feature of this microphone suspension boom arm is its ability to rotate 360 degrees. This is particularly useful in those moments when you get a sudden inspiration to record. You can instantly manipulate the position and angle to suit your needs. The M8 monitor arm, combines incredible weight capacity with a stylish, slim profile. 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. Humanscale Mflex Monitor Support System

The Workstream by Monoprice single monitor arm is a no-frills solution that delivers basic monitor arm features at an exceptionally low price. When considering which microphone suspension boom arm stand is the best option, it’s important to consider certain factors. Depending on what you intend to record, the attributes you require will differ. In this section, I will outline some of the key features you need to look out for when choosing the best desktop stand for your needs. Boom Arm Rotation 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. 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.
