Best monitor arms 2024: The ultimate in flexibility

A quality monitor arm is one of the best upgrades you can make to your home office setup. A monitor arm gives you more ways to move and position your display/s around your desk, and it can free up usable space on your desk surface. Plus, a monitor arm can make your desk setup look really cool.

The only catch is the price. Most monitor arms worth buying will cost close to $200, and heavy-duty arms capable of holding two large displays are even pricier. The good news is that if you buy a good-quality monitor arm, you’ll likely never need to replace it. That’s why it’s important to choose wisely with your first monitor arm purchase.

To help you with that, we’ve put several popular monitor arms through their paces to find the best of the bunch. Below you’ll find our curated list of recommended monitor arms, with thorough explanations of what qualities made them stand out. And below that, we point out some arms that we weren’t so keen on — to provide a point of comparison.

If you’re still on the fence about whether a monitor arm is worth the money and the time it takes to set up, read our article that answers why a monitor arm is most definitely worth it.

If you’re looking for a new monitor to go with your monitor arm, see our roundups of the best monitors and best home office monitors for recommendations.

Updated September 3, 2024 to include our pick for the best upscale dual monitor arm. It’s quite conceivable that you will only ever purchase one monitor arm in your life — if you choose wisely. So while the Clearspace Uni-2 is pricey, it offers the kind of top quality and features that could make it a forever monitor arm for your home office. Learn more in the summary below.






Ergotron LX – Best monitor arm




























Best Prices Today:



$275 at CDW





The Ergotron LX is a sturdy, practical monitor arm that can handle most monitors. It’s easy to set up, easy to use, and (when purchased in its white or polished aluminum colorway) attractive.

Ergotron positions the LX as an entry-level monitor arm, but the company’s definition of “entry level” exceeds most competitors. The arm is primarily constructed from metal, with some plastic cladding, and can support monitors that weigh up to 25 pounds. Ergotron recommends sticking to monitors 34 inches wide or smaller. The monitor arm is backed by a 10-year warranty.

The arm has a healthy range of adjustment that includes 13 inches of lift, 75 degrees of tilt, 360 degrees of rotation, and 360 degrees of pan (or swivel). While not as smooth as the Herman Miller Flo, I was able to adjust the monitor arm left, right, forward, and back without standing.

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.

Ergotron also avoids any serious flaws. I have a few nitpicks, sure. I think the clamp could be smaller. The white colorway doesn’t have a color coordinated VESA mount. And the arm’s overall design looks a bit industrial. Still, this is a bomb-proof mount, and it’s available under $200.  







Workstream by Monoprice – Best budget monitor arm





























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).

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.

The Workstream’s slim budget is felt in its difficult setup and stiff operation. Users will need to install several screws for a clamp or gromet mount. More screws may need to be adjusted once the arm is in place, as its default tension proved inadequate for supporting a 32-inch monitor.

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.

These flaws are easily excused by the Workstream’s $60 price tag. It’s clearly less capable, less attractive, and more difficult to use than Ergotron’s LX, but it offers a good range of adjustment and durable construction for less than half the price. It’s an ideal choice for shoppers on a tight budget, as well as those who plan to install a small, light 24-inch or 27-inch monitor.








Huanuo HNSS6 Single Monitor Arm – Best monitor arm under $50





























The Huanuo HNSS6 Single Monitor Arm is easily our go-to recommendation for shoppers looking to buy the least expensive monitor arm that can still fulfill its job.

The arm comes in two pieces: The lower portion swivels while the upper portion allows for height, tilt, and rotation adjustments. A gas spring provides tension to keep monitors aloft, which is an upgrade from the clips and screws used by the least expensive arms. However, it’s worth noting that gas springs can lose their potency over time. These features are typical for the price: Most competitors are similar in design and use a gas cylinder.

What makes the Huanuo a winner is its overall quality and ease of install. Setup required installation of just three screws (and adjustment to a couple more). The clamp used to mount the arm to the desk was intuitive compared to rivals like the MountUp Single Monitor Arm, as the spacing of the clamp is adjustable without removing and re-installing screws to secure it. The arm claims to hold 32-inch displays up to 20 pounds, which is enough to hold most monitors. We tested it with panels up to 32 inches weighing up to 12 pounds, and it supported those with ease.

One notable downside is cable management. The plastic covers provided are finicky and won’t hold many wires, so if you want to add USB cables in addition to a video connection and power, you’re probably out of luck. To be fair, though, the same is true of most inexpensive arms.

The Huanuo wasn’t as easy to set up or adjust as the Ergotron LX, our favorite overall pick, and it’s not as sturdy as the Monoprice Single Monitor Arm, which typically sells for $60. Still, the Huanuo gets the job done.







Herman Miller Flo – Best upscale monitor arm




























Best Prices Today:



$295 at Herman Miller





Want a monitor arm that gets the job done and looks good doing it? The Herman Miller Flo is for you.

The Flo’s design sets it apart from the pack. Herman Miller ditches the angular, industrial design of many competitors for a smooth, natural look. While clearly designed for a corporate office, it also fits in with a home office setup, where its friendly, approachable look helps it blend in with its surroundings. The Flo is backed by a 12-year warranty and offers 24/7 customer service.

It’s easy to set up and use. The monitor’s clamp works similarly to other monitor arms I tested, but it’s more refined and requires fewer screws (a grommet is also available). The VESA mount is also excellent, providing a simple clip design that’s secure and can be easily pre-mounted to a monitor for simple installation. The way this mount works accommodates monitors that have a slightly recessed mount position, which may cause problems for other monitor arms.

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.

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.

Herman Miller lists the Flo at $295, which is a lot to ask for a single-monitor arm. The Ergotron LX offers similar features at a much lower price. However, the Flo is a smoother, more appealing monitor arm, and worth the upgrade if you want form with your function.







Ergotron HX – Best heavy-duty monitor arm




























Best Prices Today:



$349 at CDW





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.

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 use of plastic is minimal and reserved for small portions of cladding that appear used only for cable routing. The arm’s moving parts include larger, sturdier mechanisms, and felt extremely smooth in my use. Ergotron backs the arm with a 10-year warranty.

The monitors range of adjustment is a bit limited compared to the LX. It offers 11.5 inches of height, 75 degrees of tilt, 180 degrees of swivel, and 360 degrees of rotation. However, a somewhat more limited height adjustment is typical in this category due to the size of monitors these stands are expected to carry.

The monitor arm’s impressive design also provides a more robust look. This could be a con for some, however, as the arm can seem a bit…much in a home office setup. It’s an expensive arm, as well. Expect to pay about $350.

The Ergotron HX is an obvious choice if you want to mount an ultrawide, super-ultrawide, or large format widescreen monitor on your desk.







Humanscale M2.1 with M/Connect – Best monitor arm w/ built-in dock




























Best Prices Today:



$356 at Humanscale





The Humanscale M2.1 with M/Connect laptop docking station is an attractive, robust, and modern monitor arm that can expand your laptop’s connectivity without taking up additional space on your desktop.

Humanscale’s entry-level M2.1 doesn’t include a laptop dock, but it’s designed to accommodate the M/Connect 3, which nestles snuggly into the base of the arm. Most home office shoppers will likely choose the M/Connect 3 USB Data Hub, which currently retails for $253 (on top of the M2.1’s base price of $356). The hub adds three USB-C ports and two USB-A ports. If you want even more ports, the $600 M/Connect 3 Pro Dock adds two more USB-A ports, two more USB-C, Ethernet, and two DisplayPort ports.

The M/Connect 3’s added connectivity is an excellent way to expand the ports on a laptop. Its central location makes the ports easy to access and keeps them firmly located in a set position on your desk (as opposed to freestanding hubs and adapters, which tend to get shoved around, or off, a desk). It’s also a good alternative to a USB-C monitor. We like USB-C monitors, but packing connectivity into the monitor can make it difficult to access some ports, as most are located on the rear of the display.

Connectivity aside, the Humanscale M2.1 is a robust, if conventional, monitor arm. It can handle monitors between 5 and 15 pounds, which is enough to support the vast majority of widescreen monitors under 32 inches in size. It also has a “smart stop” feature, which lets users customize the amount of rotation the arm allows, and easy-to-use quick release joints that are handy when disassembling or moving the arm. The arm isn’t as smooth in operation as the Herman Miller Flo, but it remains easy enough to adjust.







Ergotron LX Dual Monitor Arm – Best dual monitor arm




























Best Prices Today:



$415 at CDW





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.

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).

Look and feel is otherwise similar to the standard Ergotron LX, and that’s why the dual monitor arm also earns a recommendation. The dual-monitor arm provides the same winning balance of build quality, adjustability, and smooth operation, and it’s backed by the same 10-year warranty.  Pricing is a bit higher at $330, which is a slight savings compared to buying two LX arms individually.







Workstream by Monoprice Dual Monitor Arm – Best budget dual monitor arm




























Best Prices Today:



$99.99 at Monoprice





The same logic that applies to our favorite dual monitor arm also to the budget model, giving Monoprice’s Workstream Dual Monitor Arm a clear path to victory.

In fact, the dual arm’s pricing is even more impressive. The Workstream Dual Monitor is four times less expensive than the Ergotron LX Side-by-Side. I’m a bit shocked by the quality Monoprice can offer at a $100 price point. Ergotron’s alternative is more attractive and easier to use, but is it four times better? That’s a tough call.

The Workstream’s downsides are identical to standard model. Build quality is impressive for the price, but the arm is difficult to set up and not as smooth in operation. I’m also doubtful the arm is capable of handling two 20-pound monitors, as its spec sheets claim. Fortunately, 27-inch monitors (the largest this arm can handle side-by-side) usually weigh less than 10 pounds, so weight capacity shouldn’t be an issue.







Huanuo HNDS12 – Best mid-range dual monitor arm




























Best Prices Today:



€94.89 at Amazon DE





The Huanuo HNDS12 represents a middle ground for shoppers who want an upgrade in quality but need to respect their budget.

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.

There’s one unusual feature: a USB hub. This includes two USB ports that are placed at the front of the arm base. Each of these will need to plug in to your computer, which might be a problem if you have a laptop with just a few ports, but it’s a functional bonus.

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. 

Still, the HNDS12 is a good pick at its regular retail price of $140, which often drops as low as $110 when on sale. It looks attractive and offers plenty of force for holding larger monitors.
