Ergotron LX Dual
3 sources2 derived$439.99as of Aug 1
Why it's ranked here

The Ergotron LX Dual is the gold standard for dual monitor arms. Its all-aluminum build and patented Constant Force motion deliver the smoothest adjustment and the most rock-solid stability of any arm in this group, backed by a 10-year warranty. Reviewers across PCWorld, Work While Walking, and BTOD treat it as the benchmark. It costs more than budget steel stands and caps at about 20 lbs per arm, but for everyday dual-27-inch setups it is the most reliable choice.

Strengths
  • All-aluminum construction is the most stable arm reviewers have tested
  • Patented Constant Force (CF) motion needs no knobs or levers to adjust
Watch-outs
  • Per-monitor weight tops out around 20 lbs, less than the heavy-duty HX
  • Limited vertical range can be short for very tall standing-desk users
Ergotron HX Dual

Ergotron HX Dual
3 sourcesall derived$550.8as of Aug 1
Why it's ranked here

The Ergotron HX Dual is the heavy-duty choice: a premium arm built to carry large, heavy monitors and ultrawides that would overload a standard LX. Reviewers praise its top-notch materials, finish, and engineering, with a 10-year warranty to match. It is the most expensive arm here and overkill for light setups, and reviewers note a touch of wiggle in the mounts, but for big-screen, high-mass dual configurations it is the most capable option.

Strengths
  • Heavy-duty design supports large, heavy monitors and ultrawides
  • Even nicer finish and materials than the standard LX, per reviewers
Watch-outs
  • Most expensive arm in this group by a wide margin
  • Reviewers note slight wiggle between the monitor mounts and arms
Monoprice Workstream Dual Monitor Arm
#3
Best for: Budget buyers who want full gas-spring articulation for monitors up to 34 inches without paying premium prices.
Monoprice Workstream Dual Monitor Arm
1 sourceall derived$128.72as of Aug 1
Why it's ranked here

The Workstream by Monoprice Dual is the budget gas-spring pick: PCWorld names it the best budget dual arm, noting it costs about four times less than the Ergotron LX Side-by-Side while supporting monitors up to 34 inches and 19.8 lbs per arm. Its steel-and-aluminum build is sturdier than all-plastic stands, but setup is awkward and the motion isn't as smooth as premium arms. For a low-cost full-motion dual setup, it is a sensible value choice.

Strengths
  • Roughly four times cheaper than the Ergotron LX Side-by-Side
  • Gas-spring counterbalance handles monitors up to 34 inches
Watch-outs
  • Setup is difficult and operation isn't as smooth as premium arms
  • Gas springs can need re-tensioning over time
VIVO Dual Monitor Desk Mount (STAND-V002)
#4
Best for: Bargain hunters who want a sturdy, no-frills steel mount for two moderately sized monitors and do not need spring-assisted adjustment.

1 sourceall derived$40as of Aug 1
Why it's ranked here

The VIVO STAND-V002 is the rock-bottom budget pick: a heavy-duty steel dual mount, often around $40, that holds two monitors up to 30 inches and 22 lbs each. Long-term owners praise its solid, wobble-free build and durability, though it offers no gas-spring assist or cable management, so adjustment is manual and clunky. PCWorld was harsh, calling it the worst arm in its test, but for buyers who want maximum sturdiness at minimum cost, it remains a popular, functional choice.

Strengths
  • Extremely affordable, often around $40
  • Heavy-duty steel construction feels solid and stable
Watch-outs
  • No gas-spring assist; adjustment is manual and less convenient
  • No integrated cable management on the base model
