The Best Dual Monitor Arms in 2026

This is the dual mount most people should buy. It's two fully independent gas-spring arms on one shared base, so each screen floats to its own height, angle, and depth one-handed — the thing a rigid crossbar can't do. That independence is exactly what makes it forgiving of a mismatched pair: a 27-inch main next to a smaller 24, or one screen turned portrait, all line up without a fight.

HUANUO publishes the DS18 at 22 lbs per arm for 17–32 inch flat or curved screens on 75×75 or 100×100 VESA, with 17.5 inches of height above the desk and 15.4 inches of forward reach. Both mounting options are in the box, and the ranges are specific: the C-clamp takes desktops 0.39 to 2.56 inches thick, the grommet mount 0.39 to 2.17 inches. That 22 lb figure ties the highest per-arm rating in this guide — the VIVO and the Ergotron match it — but only two of those three let you actually spend it twice. Ergotron caps the pair at 40 lbs; HUANUO, like VIVO, publishes no combined total at all, so on this mount the two arms are genuinely independent budgets. It is the only gas-spring arm here that gives you both.

Two honest limits, both of them HUANUO's own words rather than ours. First, the company states the mount is not compatible with particle board or softwood desktops — that is a flat exclusion, not a caution about heavy panels, and it disqualifies a lot of flat-pack desks outright. If that's your desk, the clamp-versus-grommet decision is where to start, because bolting through the surface spreads load in a way a clamp cannot. Second, HUANUO publishes no minimum monitor weight, so if you hang something very light on an arm tuned for 22 lbs, finding the tension is trial and error. The warranty is published as "up to 5 years" — the hedge is theirs.

The V002 is the cheapest honest way to get two screens off the desk, and the trade-off is right there in the mechanism: it's a fixed friction-joint mount, not a gas spring. You loosen the joints, position each screen, and tighten them back down — there's no one-handed float. In exchange VIVO rates it at a genuine 22 lbs per monitor for 13–30 inch screens, which is a lot of capacity for $39.99.

Both arms articulate independently on a shared 17-inch pole, with 16 inches of height travel along it, so you can still angle and tilt each screen separately once it's set. C-clamp and grommet hardware are both included and it fits desktops up to 3.25 inches thick — the widest desk range in this guide. VIVO also publishes a 3-year warranty, which is more than North Bayou states for anything.

Two things to know before you buy. Because it's friction-held rather than counterbalanced, heavier screens can slowly droop inward over months until you re-tighten the joints, and repositioning is a two-hands, loosen-and-lock affair. And check the model number rather than the family: VIVO sells the STAND-V032 for 13–32 inch screens and the STAND-V038 for 13–38 inch on the same pole design, so if your panels are bigger than 30 inches the V002 is the wrong SKU rather than a tight fit.

North Bayou builds the budget arms other brands quietly rebrand, and the F160 is its dual gas-strut done right for the mainstream case: two matched 24–27 inch monitors sitting level and symmetrical on one gloss-black base. Each arm is rated 4.4 to 19.8 lbs (2–9 kg), and it is one of only two picks here that publish a minimum weight as well as a maximum — the Ergotron's 7 lb floor is the other, at several times the price. That number matters more than it sounds, because a gas strut tuned below its floor pushes a light screen upward on its own. At 4.4 lbs the F160 has the lowest floor in this guide, so it is the safer of the two for a small or unusually light second panel. The base also carries two USB 3.0 pass-through ports, though whether the cables are in the box depends on which configuration you buy.

It fits both 75×75 and 100×100 VESA, includes clamp and grommet mounts, and gives 10 inches of upright travel with about 21 inches of extension. The clear ceiling is size, and it is worth being precise about where that ceiling is: North Bayou's global and US listings publish 17–27 inches, while its Australian listing for the same model publishes 17–30. Buy it for a pair of 27s and the discrepancy never bites; buy it hoping for 30-inch panels and you are relying on the more generous of two numbers the same company prints.

Two caveats you should price in. North Bayou publishes no warranty term at all — not a short one, none — which is consistent with what we found across its single arms too. And the F160 is now the oldest dual in its own lineup: North Bayou's current duals are the G35 (22–32 in, 4.4–26.4 lbs per arm), the G75 (up to 32 in, 6.6–26.4 lbs) and the G65 (27–34 in, 11–35.2 lbs). The F160 has not been replaced, but if your screens are over 27 inches the answer is a different North Bayou, not this one. There is also no published US list price — North Bayou's own storefront shows $276 for a USB-cabled configuration, an order above what US retailers charge, so treat any F160 price you see as retailer-set.

The MI-1772 is the arm to buy when you want the coverage rather than the badge. Mount-It! backs it with a lifetime warranty — longer than the ten years Ergotron and Herman Miller publish, and the reason this pick holds its award. Two independent gas-spring arms run from one silver post on a single clamp, rated 19.8 lbs per arm for 13–32 inch screens, with 13 inches of vertical travel, 45° of tilt, 180° of swivel and 360° of rotation for portrait work.

Read the load line carefully, because this is where dual mounts mislead. Mount-It! publishes 19.8 lbs per arm and a 40 lb total — those numbers are consistent with each other, which is exactly why they are worth quoting: 19.8 × 2 is 39.6, so both arms can be loaded to their rating at once. That is not true of every mount in this guide, and it is the question to ask of any dual before you hang two heavy panels on it.

Hardware covers 75×75 and 100×100 VESA with clamp and grommet bases, in silver (MI-1772) or black (MI-1772B). The honest catch is the price: Mount-It! lists it at $159.99, which puts it within about $25 of a discounted Herman Miller Jarvis. Against the Jarvis you get a longer warranty and slightly more per-arm capacity; against the $69.99 HUANUO you are paying $90 for the paperwork and a heavier build, not for more screen support. Like any dual, extending both arms out wide multiplies the leverage on the inner joints — keep the heavier monitor nearer the post.

Formerly sold as the Fully Jarvis Dual and now carried by Herman Miller, this is where the jump from mid to premium starts to justify itself. Two independent gas-spring arms hold 13–32 inch monitors up to 19 pounds each, with tool-free tension tuning, 360° swivel and clean portrait/landscape rotation on each arm. Herman Miller publishes 13.2 inches of height adjustment, topping out at 19.8 inches above the tabletop measured at monitor centre. The motion is refined in a way the budget duals aren't, and it holds its position for years rather than months.

Nineteen pounds is the number to check against your panels, not twenty — it is the lowest per-arm rating in this guide, and most 32-inch monitors are heavier than most 27s by more than you'd guess. Weigh the screen without its factory stand before you commit. VESA covers 75×75 and 100×100 with clamp and grommet hardware, and the arm carries a 10-year warranty, which is the coverage that turns this into a buy-once decision rather than a purchase you revisit.

Herman Miller lists it at $245, and it is frequently discounted — it was $183.75 when we last checked, which is real money off but not a permanent price. One genuine risk: MillerKnoll shut Fully down in April 2023, so secondhand Fully-branded units carry no manufacturer support. Buy it new from Herman Miller for a setup you'll live with daily and it's the value pick of the premium tier.

Every other pick here puts your screens side by side, which needs desk width you may not have. The tall-pole LX Dual Stacking Arm solves the narrow-desk problem by going vertical: a 22-inch pole carries two arms that stack one screen above the other, each with 13 inches of lift, 75° of tilt and 360° of pan and rotation. It supports screens up to 40 inches — by a wide margin the highest size ceiling in this guide.

Check the model number, because Ergotron sells two arms under almost the same name and they are not interchangeable. The tall-pole 45-509 is the one rated 7 to 22 lbs per monitor for screens up to 40 inches; the standard 45-248 rides a 12-inch pole and stops at 24-inch screens at 7 to 20 lbs. And there is a ceiling above both per-arm figures: Ergotron publishes a 40 lb combined limit, so two monitors at the 22 lb maximum — 44 lbs together — is a configuration the mount's own spec sheet does not allow. Budget for a heavy screen plus a lighter one, not two heavy ones.

It uses Ergotron's mechanical Constant Force spring rather than a gas strut, which is why sag complaints are rare and Ergotron is comfortable publishing a 10-year warranty — there's no gas to leak. Clamp hardware takes desk edges 0.63 to 2.6 inches thick and a grommet plate is in the box. The catch is the tall pole: it raises the centre of gravity, so it wants a solid, thick desk, and stacking two large screens can push the top one uncomfortably high. At a $529 list it costs roughly as much as the other five picks put together — but it's the arm for a narrow desk or a permanent over-under layout.
