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.

Instead of using a gas cylinder to counterbalance the weight of the monitor, the M2 monitor arm uses extension spring technology. Without clunky mechanisms to complicate the design, the M2 offers uncompromising lightweight, long-term durability and an ultra-thin design that complements flat-panel monitors and attachments for a truly flexible workstation. Humanscale M8 Monitor Arm Smoothness of motion: We preferred monitor arms that were firm enough to stay put while we worked but could reposition easily and didn’t require too much force. 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.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. 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. The Workstream by Monoprice single monitor arm is a no-frills solution that delivers basic monitor arm features at an exceptionally low price. 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.

By redefining the capabilities of a monitor arm, Humanscale created the M8, which combines incredible weight capacity with a stylish, slim profile. Like all Humanscale monitor arms, the M8 allows the user to work in a healthy posture through setting one or multiple monitors at an optimal distance and height, collaborate easier through effortless screen sharing, and increase desk space. As the pioneer and leader of office ergonomics, Humanscale makes products that allow workstations to adapt to the user, not the other way around. Founded in 1983 by CEO Robert King with a focus on high-performance tools that support a healthy, more active way of working, Humanscale is now the global ergonomics leader with a reputation for designing intuitive products which improve the comfort and health of office workers. Brand leading Monitor arm support systems such as the M2 & M8 monitor arms and the scalable MFlex monitor support system that allows additional monitor supports, up to six, to be added as the need arises. 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. 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.
