What are the best dual monitor arms in 2026?
Best Dual Monitor Arms in the US — October 2026
Answer: Our top pick is the HUANUO DS6 Dual Monitor Arm (HNDS6): TechRadar calls it a monitor stand with loads of movement and says a sturdy C-shaped clamp holds it firmly on a desk. (Sources: techradar.com)

TL;DR
Top pick: HUANUO DS6 Dual Monitor Arm (HNDS6) — the only arm on this card with two independent hands-on reviews of the listing we link: BTOD's value pick, which held two 27-inch monitors and raised them to eye level, and PCWorld, which calls it a decent dual arm for the price. Sold on Amazon as the FlowLift Dual, for two 13-32-inch screens. HUANUO's page rated each arm for 19.8 lbs when we checked on 2026-10-14, but both testers give 14.3 lbs, so plan on 14.3 lbs until a tester confirms the higher figure. [src3, src1, src10]
Why this pick: no other arm on this card has two independent tests of the configuration we link. The guides rank different arms first: BTOD the Ergotron LX Dual Stacking Arm, Tall Pole, PCWorld the Ergotron LX Dual Side-by-Side, and Tom's Guide the Vari Dual-Monitor Arm (and, for stacking, the LX Dual Stacking arm on its 13-inch pole, rated for screens up to 24 inches, a different configuration from the Tall Pole we link). [src3, src1, src2, src7]
No value pick this cycle: the one arm here with two independent reviews is the top pick, and we do not award a slot on a single review.
Availability: HUANUO's US store listed the top pick as available when we checked on 2026-10-14. [src10]
Also tested: Ergotron LX Dual Stacking Arm, Tall Pole — BTOD's best dual arm ("clearly the best arm on the list"), for two screens up to 40 inches at 7-22 lbs each, stacked or side by side, with a 10-year warranty; one hands-on test of this Tall Pole configuration. [src3, src7, src9]
Also tested: Ergotron LX Dual Side-by-Side — PCWorld's best dual-monitor arm, for two screens up to 27 inches. [src1]
Also tested: Vari Dual-Monitor Arm — Tom's Guide's best arm for dual monitors, which Tom's Guide could fit only to desks about 2.25 inches thick or less; Vari's spec sheet gives a maximum desk thickness of 1 3/8 inches. [src2, src13]
Also tested: Mount-It! Full Motion Dual (MI-2752) — Tom's Guide's best cheap dual arm, but both screens sit at the same height. [src2]
Also tested: HUANUO DS7 (HNDS7) — for two screens up to 40 inches; Techaeris, which reviewed it, says you cannot beat it for the price. [src6]
Today's prices and stock are in the table at the top of the page.
Summary
A dual monitor arm clamps one base to the desk edge, or bolts it through a grommet hole, and carries two screens on one pole, so both can be raised, pushed back and turned without two stands on the desk. The guides that put dual arms on real desks keep returning to Ergotron's LX dual arms, and split on the cheaper ones, but each ranks a different arm first: BTOD's best dual arm is the Ergotron LX Dual Stacking Arm, Tall Pole, PCWorld's is the Ergotron LX Dual Side-by-Side, which "pairs two LX monitor arms together on one mount", and Tom's Guide's best for dual monitors is the Vari Dual-Monitor Arm [src1, src2, src3]. Each of those has one hands-on test of the configuration we link. Tom's Guide's stacking pick is a different configuration again, the LX Dual Stacking arm on its 13-inch pole, which Ergotron rates for screens up to 24 inches against the Tall Pole's 40 [src2, src7].
Our top pick is the HUANUO DS6 (HNDS6) because it is the only arm on this card that two outlets tested independently, on the listing we link. BTOD made it its value pick, found it sturdy once set up, and it raised two 27-inch monitors to eye level [src3]. PCWorld tested the same Amazon listing and calls it "a decent dual-monitor arm for the price and worthwhile on a discount", but prefers the Workstream by Monoprice Dual Monitor Arm, its best budget dual arm [src1]. We do not link the Monoprice: Wirecutter reports that the dual-monitor Monoprice Workstream 15525 "failed to hold our test 24-inch monitors in place" [src5]. Tom's Guide's cheap option is the Mount-It! Full Motion Dual (MI-2752) [src2], and Techaeris reviewed the HUANUO DS7 (HNDS7), HUANUO's 40-inch model, and says "you cannot beat the HUANUO DS7 for the price" [src6].
Wirecutter disagrees with the whole category: "After testing a few dual-monitor arms, we've concluded that the best option for people who have two monitors is getting two single-monitor arms instead," because each screen can then be positioned, angled and rotated more precisely, which matters most with two monitors of different sizes [src5]. If that is you, see Best Single Monitor Arms (2026).
Top 6 Models Compared
The table's prices are refreshed from our latest check of the exact listing each row links; a dash means we have no current price for that listing. Weight ranges give the arm's minimum and maximum load per screen.

Dual-Setup Fit Checks
- Weight has a floor, not just a ceiling. The Ergotron LX dual arms need at least 7 lbs per screen (7-22 lbs on the Tall Pole stacking arm, 7-20 lbs on the Side-by-Side), and HUANUO's DS6 and DS7 at least 4.4 lbs [src8, src9, src10, src12]. PCWorld notes that most 24- and 27-inch monitors weigh 10 pounds or less, so check a light 24-inch panel's weight without its stand against the 7 lb floor before choosing an Ergotron [src1]. Vari and Mount-It! give only a maximum, 19.8 lbs per arm [src13, src14].
- The rated maximum is not always what the testers saw. PCWorld and BTOD both give the HUANUO DS6's arms 14.3 lbs, where HUANUO's page now says 19.8 [src1, src3, src10]. On the Ergotron Tall Pole stacking arm the capacity per screen falls as screens are added: 7-22 lbs each with two, 7-14.6 lbs with three, 7-11 lbs with four [src4].
- Independent arms, or one height for both. Each Ergotron LX dual arm carries two separate LX arms [src1, src9], and BTOD set the HUANUO DS6 up with one screen horizontal and one vertical [src3]. The Mount-It! MI-2752 is different: Tom's Guide found its two arms are connected in a way that prevents you from mounting the screens at different heights [src2].
- Desk thickness and material. The Ergotron LX dual arms clamp desk edges 0.63-2.6 inches thick [src8, src9]. HUANUO recommends only wooden desks 0.59-3.54 inches thick for the DS6, with no cross-beam under the clamp, and says plastic or glass desks cannot be used [src11]; the DS7 takes desks up to 3.54 inches [src6]. Tom's Guide could not fit the Vari to a desk thicker than about 2.25 inches, and Vari's own spec sheet marks 1 3/8 inches at the clamp [src2, src13]. Mount-It!'s listing gives up to 4 inches for its clamp and 3.25 inches for its grommet base [src15].
- Desk width for side by side, height for stacking. A 27-inch 16:9 panel is about 23.5 inches wide, so two side by side need about 47 inches before bezels. The Ergotron LX Dual Side-by-Side's arms are not long enough for two 32- or 34-inch monitors side by side, and it stacks only if one screen is under 23 inches [src1]. The Tall Pole stacking arm's 23-inch pole raises a screen up to 31.7 inches above the desk [src9]. Wirecutter adds that on a desk pushed against a wall, two screens side by side must come forward about 12 inches, too close for comfort on a desk 30 inches deep or less [src5].
- Ergonomics. OSHA's workstation guidance puts the preferred viewing distance at 20-40 inches, the top of the screen at or slightly below eye level, the screen centre 15-20 degrees below horizontal eye level, and no monitor farther than 35 degrees to the left or right [src16]. With two screens, angle both inward so each stays inside that range. This is general workplace guidance, not medical advice; see a clinician for persistent neck, shoulder or eye pain.
Best for Each Use Case
Top Pick: HUANUO DS6 Dual Monitor Arm (HNDS6) — Check price
The only arm on this card that two outlets tested independently, on the listing we link, which is why it is the top pick. It is BTOD's value pick of the five Amazon dual arms it tested, which BTOD calls the Huanuo Dual Spring Arm and links to the same Amazon listing as this card: "The spring mechanism held its own with two 27″ monitors and raised them to eye level, which the WALI couldn’t do." BTOD found it sturdy once set up and could run one screen horizontal and one vertical, but notes two desk clamps, a lot of plastic and cable management that is a hassle to set up [src3]. PCWorld tested the same Amazon listing and calls it "a decent dual-monitor arm for the price and worthwhile on a discount", at a typical $60: the metal construction "feels rigid and looks durable" and gave plenty of lift, but installation takes two clamps and roughly a dozen screws, the cable routing is hard to tighten, and PCWorld thinks the Monoprice Workstream Dual Monitor Arm "provides more for a similar price" [src1]. Both testers give its arms 14.3 lbs each, enough for most 24- and 27-inch monitors [src1, src3]; HUANUO's page now rates the DS6 for 13-32-inch screens at 4.4-19.8 lbs per arm, with up to 15.75 inches of lift and a warranty of up to 5 years [src10]. Until a tester confirms the higher figure, plan on 14.3 lbs. HUANUO's Amazon listing, where it is sold as the FlowLift Dual, recommends only wooden desks 0.59-3.54 inches thick, says plastic or glass desks cannot be used, and wants no cross-beam or panel under the clamp [src11]. HUANUO's US store listed it as available when we checked on 2026-10-14 [src10].
Also Tested: Ergotron LX Dual Stacking Arm, Tall Pole (BTOD's best dual arm) — Check price
BTOD bought five popular dual arms on Amazon and tested them on its own desk setup; this Tall Pole arm, the most expensive of the five, was "clearly the best arm on the list. The build quality difference is immediately obvious out of the box. Worth the premium if you have large monitors or care about long-term reliability." BTOD found almost every part metal and the arm "super strong and sturdy", with ample post height, and stacking two monitors worked; its complaints are that attaching the monitors takes time and patience and that cable management is zip ties [src3]. BTOD's 2026 tier list of 20 arms puts it in S tier as the best arm for stacking monitors, at over $400 [src4]. The Tall Pole version this card links is rated for two screens up to 40 inches and 7-22 lbs each, has a 23-inch pole that raises a screen up to 31.7 inches above the desk, clamps desk edges 0.63-2.6 inches thick or mounts through a grommet hole, takes a third and fourth arm with Ergotron's add-on kit (98-130-224), and has a 10-year warranty [src7, src9]. Tom's Guide's stacking pick is a different configuration, the LX Dual Stacking arm on its 13-inch pole, which Ergotron rates for screens up to only 24 inches, so it is not a second test of this one [src2, src7]. It is not ranked because BTOD is the only outlet we read that tested this Tall Pole configuration (its two articles are one outlet); stock is not the reason. Availability: when we checked on 2026-10-13, the Amazon listing we link had no offer, and Ergotron's own store refused our connection, so we could not check it.
Also Tested: Ergotron LX Dual Side-by-Side (PCWorld's best dual arm) — Check price
PCWorld's best dual-monitor arm: "The Ergotron LX Side-by-Side pairs two LX monitor arms together on one mount," with "the same winning balance of build quality, adjustability, and smooth operation" as the single LX and the same 10-year warranty, at $470 when PCWorld priced it. Its arms are rated for monitors up to 27 inches and are not long enough for two 32- or 34-inch monitors side by side, and it stacks screens only if one is smaller than 23 inches [src1]. Ergotron's listing gives 7-20 lbs per screen, a clamp for desk edges 0.63-2.6 inches thick or a grommet mount, and 13 inches of lift rising 15.6 inches from the desktop [src8]. It is not ranked because PCWorld is the only guide we read that tested it; it was this card's top pick before this refresh. Availability: the Amazon listing we link had no purchasable offer in our last three daily checks, through 2026-10-13.
Also Tested: Vari Dual-Monitor Arm (Tom's Guide's best for dual monitors) — Check price
Tom's Guide's pick for two monitors: "well-designed, strong and supports dual monitors up to 27 inches each." Against it, setup is relatively complicated and takes longer than average, it is a little expensive, and it fits only desks of around 2.25 inches or less — Tom's Guide tried a thicker desk and could not install it [src2]. Vari's page recommends 16:9 monitors up to 27 inches and gives a 10-year warranty (Tom's Guide's spec box says 5 years), and its spec sheet gives 19.8 lbs per arm and marks 1 3/8 inches at the desk clamp, so measure the desk first [src13]. Vari's US store listed it in stock when we checked on 2026-10-14 [src13]. It is not ranked because Tom's Guide is the only guide we read that tested it.
Also Tested: Mount-It! Full Motion Dual Monitor Desk Mount, MI-2752 (Tom's Guide's best cheap dual arm) — Check price
Tom's Guide calls the Mount-It! Full Motion Dual "a solid choice for those who want to mount dual monitors while paying as little as possible": relatively easy to set up, with arms for monitors up to 32 inches, at around $35 when Tom's Guide priced it. Its serious limitation is that the two arms are connected in a way that prevents you from mounting them at different heights, and two ultrawides that large will be hard to fit [src2]. Mount-It! lists the MI-2752 for 17-32-inch screens at 19.8 lbs per arm, with ±45 degrees of tilt, ±180 degrees of arm swivel, 360-degree rotation, a 17.5-inch pole and a lifetime warranty (Tom's Guide's spec box gave 1 year); Mount-It!'s US store listed it as available when we checked on 2026-10-14 [src14]. Its Amazon listing, the one Tom's Guide links, names the same model and gives a clamp for desks up to 4 inches thick or a grommet base for desks up to 3.25 inches [src15]. It is not ranked because Tom's Guide is the only guide we read that tested it.
Also Tested: HUANUO DS7 Dual Monitor Arm, HNDS7 (Techaeris's review) — Check price
HUANUO's bigger dual arm, for two 13-40-inch screens at 4.4-26.4 lbs per arm, with aluminium-alloy arms, +85/-30 degrees of tilt, up to 21.65 inches of lift and a warranty of up to 5 years [src12]. Techaeris mounted a 32-inch 16:10 and a 34-inch 16:9 monitor on it and found the arms glide easily: "Overall, you cannot beat the HUANUO DS7 for the price." It took about half an hour to assemble and ten minutes to adjust; the cable channels are too narrow for several thick cables, the covers are finicky, and the springs take fine-tuning to hold the monitors. Its base takes clamp or grommet mounting on desks up to 3.54 inches and holds two USB ports [src6]. HUANUO's US store listed it as available when we checked on 2026-10-14 [src12]. It is not ranked because Techaeris is the only outlet we read that tested it.
Head-to-Head Comparisons
Ergotron LX Dual Stacking Arm, Tall Pole vs Ergotron LX Dual Side-by-Side
Both carry two Ergotron LX arms and a 10-year warranty [src1, src7]. The Tall Pole stacking arm takes screens up to 40 inches at 7-22 lbs each on a 23-inch pole, stacked or to either side; the Side-by-Side takes screens up to 27 inches at 7-20 lbs each, and stacks only if one screen is under 23 inches [src1, src8, src9]. BTOD picked the Tall Pole stacking arm and PCWorld the Side-by-Side; no guide we read tested both, and each has one test of the configuration we link [src1, src3].
Pick the LX Dual Stacking Arm, Tall Pole if: either screen is over 27 inches, or you want to stack them.
Pick the LX Dual Side-by-Side if: both screens are 27 inches or smaller and will sit side by side.
Ergotron LX Dual Stacking Arm, Tall Pole vs HUANUO DS6
BTOD tested both in the same round-up: the Ergotron was "clearly the best arm on the list", the HUANUO its value pick [src3]. PCWorld also tested the HUANUO, on the same listing, so it has the second independent test the Tall Pole lacks, and it is our top pick [src1]. BTOD puts the Ergotron at over $400 [src4], and PCWorld puts the HUANUO's typical price at $60 [src1]. The Ergotron takes bigger and heavier screens (40 inches, 7-22 lbs each) but needs at least 7 lbs per screen; the HUANUO is rated 13-32 inches and starts at 4.4 lbs [src9, src10]. The Ergotron clamps 0.63-2.6-inch desk edges; the HUANUO clamps 0.59-3.54 inches, and HUANUO recommends wooden desks only [src9, src11].
Pick the Ergotron if: you want the best-built arm BTOD tested, or screens over 32 inches.
Pick the HUANUO DS6 if: price matters most and both screens are 32 inches or smaller.
HUANUO DS6 vs HUANUO DS7
Same maker, two sizes. The DS7 takes 13-40-inch screens at 4.4-26.4 lbs per arm and lifts up to 21.65 inches; the DS6 takes 13-32-inch screens at 4.4-19.8 lbs per arm (14.3 lbs in PCWorld's and BTOD's write-ups) and lifts up to 15.75 inches [src1, src3, src10, src12]. Two testers reviewed the DS6, one the DS7 [src1, src3, src6].
Pick the HUANUO DS7 if: a screen is over 32 inches or heavier than the DS6's rating.
Pick the HUANUO DS6 if: both screens are 32 inches or smaller.
Vari Dual-Monitor Arm vs Mount-It! MI-2752
Two of Tom's Guide's dual picks. The Vari is its pick for dual monitors — well-designed and strong — but takes longer than average to set up and fits only thin desks [src2]. The Mount-It! is relatively easy to set up and takes screens up to 32 inches, but its two arms cannot be set at different heights [src2].
Pick the Vari if: both screens are 27 inches or smaller and your desk is thin.
Pick the Mount-It! if: you want to pay as little as possible and both screens can sit at one height.
Decision Logic
If build quality matters most
→ Ergotron LX Dual Stacking Arm, Tall Pole: BTOD's best dual arm, with two LX arms, screens up to 40 inches at 7-22 lbs each and a 10-year warranty; BTOD is the only outlet we read that tested it [src3, src7, src9]. When we checked on 2026-10-13, the Amazon listing we link had no offer; HUANUO's US store listed our top pick, the HUANUO DS6, as available when we checked on 2026-10-14 [src10].
If your budget is under $100
→ HUANUO DS6, our top pick and BTOD's value pick, at a typical $60 per PCWorld [src1, src3]. Tom's Guide's best cheap dual arm is the Mount-It! MI-2752, but its two screens sit at one height [src2].
If either monitor weighs less than 7 lbs
→ Not the Ergotron LX dual arms, which need at least 7 lbs per screen [src8, src9]. The HUANUO DS6 and DS7 start at 4.4 lbs [src10, src12].
If your monitors are 32-40 inches, or you want to stack them
→ The Ergotron LX Dual Stacking Arm, Tall Pole (40 inches, 7-22 lbs each) or the HUANUO DS7 (40 inches, 4.4-26.4 lbs per arm) [src9, src12]. The LX Dual Side-by-Side and the Vari stop at 27 inches; the HUANUO DS6 and the Mount-It! at 32 [src1, src10, src13, src14].
If you have a 49-inch super-ultrawide
→ No arm on this card is rated for it. PCWorld calls the single Ergotron HX "an obvious choice" for ultrawide and super-ultrawide monitors [src1]; see Best Single Monitor Arms (2026).
If your desk is thicker than 2.6 inches
→ Not the Ergotron LX dual arms (0.63-2.6 inches) or the Vari [src2, src8, src9, src13]. The HUANUO DS6 clamps up to 3.54 inches on wooden desks, the DS7 up to 3.54 inches, and the Mount-It!'s clamp up to 4 inches [src6, src11, src15].
If your two monitors differ in size, or you want each placed precisely
→ Wirecutter recommends two single-monitor arms over one dual arm [src5]; see Best Single Monitor Arms (2026).
Where the Testers Agree and Disagree
- Three testers pick an Ergotron LX dual arm. BTOD's best dual arm is the LX Dual Stacking Arm, Tall Pole, PCWorld's best dual arm is the LX Dual Side-by-Side, and Tom's Guide's stacking pick is the LX Dual Stacking arm on its 13-inch pole [src1, src2, src3]. They are three different configurations with one test each; the only arm on this card with two independent tests of the listing we link is the HUANUO DS6 [src1, src3]. PCWorld's best premium dual arm is a different one, the Clearspace Uni-2 [src1].
- No two testers pick the same budget arm. BTOD's value pick is the HUANUO DS6, PCWorld's best budget dual is the Monoprice Workstream Dual, and Tom's Guide's best cheap dual is the Mount-It! Full Motion Dual [src1, src2, src3]. Wirecutter found that a Monoprice Workstream dual arm, the 15525, failed to hold its 24-inch test monitors [src5].
- Wirecutter skips dual arms altogether and recommends two single-monitor arms for two monitors [src5].
- Ratings and tests do not always match. PCWorld and BTOD give the HUANUO DS6 14.3 lbs per arm where HUANUO now says 19.8 [src1, src3, src10]; PCWorld doubts that the Monoprice Workstream Dual can carry the two 20-pound monitors its spec sheet claims [src1]; and Techaeris's summary gives the HUANUO DS7 44 lbs where HUANUO rates it 26.4 lbs per arm [src6, src12].
Important Caveats
- Prices. The comparison table's prices come from our latest check of each linked listing. Prices quoted from the guides are what each outlet saw when it wrote, not today's: PCWorld $470 for the Ergotron LX Dual Side-by-Side and a typical $60 for the HUANUO DS6, Tom's Guide a $405 list price for the 13-inch-pole LX Dual Stacking arm and around $35 for the Mount-It!, BTOD over $400 for the Tall Pole stacking arm [src1, src2, src4].
- What left the card. The VIVO STAND-V002, this card's value pick until now, is removed: PCWorld calls it "easily the worst arm we've tested so far" — both screens adjust in height only together, its joints are tensioned by screws that must be loosened with a tool, and PCWorld saw a slight downward deflection even with a 10-pound 27-inch monitor [src1]. The WALI M002XL Extra Tall is removed because none of the guides we read tested it; BTOD tested a different WALI arm, the Dual Post Arm, and found its post too short [src3]. Also named by one guide and not linked here: the Clearspace Uni-2, PCWorld's best premium dual arm, and the Workstream by Monoprice Dual Monitor Arm, PCWorld's best budget dual [src1].
- Names. The HUANUO arm this card links is the DS6 (HNDS6) that PCWorld and BTOD tested; Amazon sells it as the FlowLift Dual [src1, src3, src11]. The Mount-It! listing is the MI-2752 that Tom's Guide tested as the Full Motion Dual [src2, src15].
- Ergotron's own site refused our connection on 2026-10-14, so the Ergotron specifications here come from Ergotron's spec sheet and the brand's Amazon listings [src7, src8, src9].
- VESA. Every arm here needs VESA 75x75mm or 100x100mm holes on both monitors; PCWorld says it is rare for a monitor to lack them, but check [src1].
- Expect setup time. Techaeris had to fine-tune the HUANUO DS7's springs to hold its monitors, BTOD found that attaching monitors to the Ergotron Tall Pole arm takes time and patience, and Tom's Guide found the Vari takes longer than average to set up [src2, src3, src6].
- Ergonomic guidance on this card follows OSHA's computer-workstation eTool. It is general workplace guidance, not medical advice — see a clinician for persistent neck, shoulder, back or eye symptoms [src16].
Changes since our last ranking
