What is the best dual monitor arm under $100?

For most home office setups, the HUANUO Dual Monitor Arm at around $45 is the best value. It gives you two independent gas-spring arms on a single pole clamp, handles screens up to 27 inches at 17.6 lbs each, and includes both clamp and grommet mounting. If you want sturdier build quality for the same money, the North Bayou F160 is the alternative pick.

Do both monitors need to be the same size for a dual arm?

No. Each arm adjusts independently for height, tilt, and rotation, so you can run two different monitor sizes as long as both stay within the arm's weight and size limits. The only thing to match is the VESA pattern, which is 75x75mm or 100x100mm on nearly all monitors.

Single-pole dual arm or two separate single arms?

A single-pole dual arm is the better choice for most people. It uses one clamp point, takes up less desk edge, and costs less than buying two single arms. Two separate single arms only make sense if your monitors are far apart or unusually heavy and you want each on its own anchor.

Will a dual monitor arm hold up on a particleboard standing desk?

Usually yes, but verify the desk edge first. A single-pole dual arm puts the weight of both screens on one clamp point, and thin particleboard edges can compress over time under that load. If your desk has a grommet hole, the grommet mount spreads the load better than an edge clamp.

Best Dual Monitor Arms Under $100 (2026)

Running two monitors changes how you work. Running them on a dual monitor arm changes how your desk feels. Instead of two bulky stands eating the back half of your desktop, you get both screens floating on a single clamp, with the whole surface underneath them free for actual work.

The good news is that a good dual monitor arm does not cost much. The best dual monitor arm for most home offices lands in the $40-$60 range, and you can get a genuinely nice gas-spring setup for under $100. This roundup covers the picks worth buying in 2026, from the tightest budget option to the best you can get without crossing the $100 line.

Why a Dual Arm Beats Two Stands

The case for a dual monitor arm is simple once you have used one. Stock monitor stands plant a wide foot on your desk and lock the screen at one fixed height. With two of them, you lose a real chunk of usable surface and you can never quite get both screens level with each other.

A dual arm fixes both problems. One clamp at the back edge of the desk holds both monitors, so the desktop underneath is clear. And because each arm moves independently, you can set both screens to the exact same height, tilt them inward to reduce neck rotation, and pull them forward or push them back to dial in viewing distance.

That last point matters most on a standing desk. Every time you switch from sitting to standing, your monitors should come up with you. A gas-spring arm makes that a one-hand, two-second motion. Two fixed stands make it a chore you will stop doing within a week.

Single-Pole vs. Two Separate Arms

There are two ways to mount dual monitors on arms:

Single-pole dual arm. Both arms attach to one vertical post on one clamp. This is what most “dual monitor arm” products are, and it is the right choice for the vast majority of setups. One clamp point, less desk edge used, lower price.

Two separate single arms. Two independent clamps, each holding one screen. This only makes sense if your monitors sit far apart, if they are unusually heavy, or if your desk layout forces it. It costs more and uses more desk edge.

Everything in this roundup is a single-pole dual arm unless noted, because that is what makes sense under $100.

The Best Dual Monitor Arms Under $100

HUANUO Dual Monitor Arm: Best Overall Value

The HUANUO dual arm is the pick I point most people to. For around $45 you get two independent gas-spring arms on a single pole, which is a lot of arm for the money. The gas spring is the important part: you push a screen up or down and it stays put, no knob to loosen first. Manual arms at this price make you fight a friction joint every time, and people quietly stop adjusting them.

Each arm handles monitors up to 27 inches and 17.6 lbs, which covers the typical dual-monitor home office. Both screens adjust independently for height, tilt, swivel, and rotation, so a portrait-plus-landscape layout is no problem. The box includes both a C-clamp and a grommet mount.

What I like: Independent gas-spring adjustment on both arms at this price is the sweet spot. The single clamp footprint is small, and the height range is enough to match both screens cleanly whether you sit or stand.

What to watch for: It is not built for large ultrawides or 32-inch panels. Stay within 27 inches and the weight limit. Check that your desk edge is at least 0.75 inches thick for a secure clamp, or use the grommet mount.

North Bayou F160: Best Build Quality for the Money

North Bayou makes the arms that get rebranded and sold under a dozen other names, and the F160 is their long-running dual mount. It uses an internal spring counterbalance rather than a gas piston, but the effect is similar: you position a screen and it holds, with no knob to fight. At roughly the same ~$45 as the HUANUO, the F160 leans toward sturdier aluminum construction and tighter joint tolerances, which shows up as less screen wobble when you bump the desk.

It fits 17-inch to 27-inch screens and rates each arm up to 19.8 lbs, which is actually a touch more headroom than the HUANUO. Adjustment range and motion are comparable.

What I like: This is the arm to buy if you have read reviews of the cheaper options and want something that feels more solid. The build quality is a clear step up for the same price, and the higher weight rating leaves room for heavier 27-inch panels.

What to watch for: The counterbalance tension is set with a screw and can take a couple of tries to dial in for your exact monitor weight. Once set, it stays put. Like any single-pole dual, confirm your desk edge is solid before clamping.

WALI Dual Monitor Mount: Tightest Budget

If your only goal is to get both screens off their stands and onto one clamp for as little as possible, the WALI dual mount is the answer. Around $35, manual friction, and a track record as one of the most-reviewed budget mounts on the market.

This is a friction arm, not gas spring, so you loosen the joint, position the screen, and retighten. For a setup where you dial in the angles once and rarely touch them again, that is a fair trade for the lowest price. WALI also rates each arm to a generous 22 lbs, higher than most of the gas-spring options here.

What I like: Cheapest reliable way into a dual arm, with a surprisingly high weight rating. Good for heavier screens that you do not reposition often.

What to watch for: Manual adjustment gets old fast if you switch sitting and standing several times a day. If you adjust often, spend the extra $10 on a gas-spring arm.

VIVO Dual Monitor Arm: Budget Set-and-Forget

VIVO is the safe budget brand for monitor accessories, and their dual arm at ~$40 is a solid manual-friction option with a long, reliable track record. Independent positioning on each screen, single-pole mount, and the same loosen-adjust-retighten workflow as the WALI.

The reason to pick the VIVO over the WALI usually comes down to whichever is cheaper on the day, or a preference for VIVO’s clamp design. Both are friction arms in the same class.

What I like: Stable, proven, and cheap. VIVO has been making this category for years and the support is there if something arrives damaged.

What to watch for: Same as any friction arm. It is fine for static setups and annoying for frequent height changes.

ErGear Dual Monitor Arm: Best for Bigger Screens

Most budget dual arms top out at 27 inches. The ErGear dual arm pushes that to 34 inches and a strong per-arm weight rating (around 19.8 lbs), which makes it the pick if your dual setup runs larger panels. It is a gas-spring arm at roughly $55, so you keep the one-hand adjustment while gaining headroom on size and weight.

The extra capacity is the whole point here. If you are pairing two 27-inch screens, or a 32-inch with a 24-inch, the ErGear has the range and the lift to handle it where the cheaper arms start to sag.

What I like: Real 32-inch support and a higher weight rating in a gas-spring arm under $60. That combination is hard to find at this price.

What to watch for: Larger screens on a single-pole dual mount put more load on one clamp. Verify your desk edge can take it, and favor the grommet mount on a thinner standing desk top.

Amazon Basics Gas Spring Dual Monitor Arm: Best Brand-Trust Pick Under $100

When you want a known brand and the simplest support path without crossing $100, the Amazon Basics gas-spring dual arm at around $90 is the call. It is a true gas-spring arm with cable management channels, a C-clamp and grommet base, and Amazon’s return policy behind it. It fits screens from 15 to 27 inches and supports up to 15.4 lbs per arm.

This is the arm for someone who wants a no-surprises buy: in stock, easy returns, and a build that feels a step above the no-name options. The repositioning is smoother than the friction arms and the integrated cable routing keeps the back of the setup tidy.

What I like: Brand trust and the easiest return path of anything here. Cable channels are genuinely useful, and the gas spring is smooth.

What to watch for: The 15.4 lbs per-arm limit and 27-inch max are lower than the ErGear, so this is not the pick for large or heavy panels. It is also double the price of the HUANUO for a refinement upgrade, not a capability leap.

What to Check Before You Buy

VESA pattern. Nearly every monitor has a 75x75mm or 100x100mm grid of mounting holes on the back. A few budget monitors do not. Confirm yours has a VESA grid before ordering any arm, dual or single.

Monitor weight and size, per arm. Dual arms list a per-arm limit, not a combined one. A 17.6 lbs per-arm rating means each screen can be up to 17.6 lbs, which covers most 24-inch to 27-inch panels. Larger or curved displays can run heavier, so weigh both screens against the rating.

Desk edge thickness and material. Clamp arms need a desk edge roughly 0.75 to 3.5 inches thick. A single-pole dual arm concentrates both screens’ weight on one clamp, so a thin or soft particleboard edge can compress over time. If your desk has a grommet hole, the grommet mount spreads the load better.

Gas spring vs. friction, honestly. If you have a standing desk and change positions through the day, pay the small premium for gas spring. If your monitors get set once and stay put, a friction arm saves you money with no real downside.

Arm reach and pole height. Check that the arm extends far enough to clear a deep desk and that the pole is tall enough to lift both screens to eye level when standing. Most arms here cover a standard depth, but deep or corner desks can need more reach.

The Bottom Line

For most dual-monitor home offices, the HUANUO Dual Monitor Arm at ~$45 is the right buy: two independent gas-spring arms on one clamp, fits the screen sizes most people run, and costs less than a decent keyboard. If you want sturdier build for the same money, the North Bayou F160 is the swap.

On the tightest budget, the WALI Dual Monitor Mount at ~$35 gets both screens onto one clamp with a high weight rating, as long as you are fine with manual adjustment.

Running larger panels? The ErGear at ~$55 handles screens up to 34 inches with gas-spring convenience. And if you want a known brand with the easiest returns under $100, the Amazon Basics gas-spring dual at ~$90 is the pick.

Whatever you choose, a dual arm is one of the highest-return desk upgrades you can make for the money. Clearing the desktop and getting both screens to true eye level pays off every single day.
