Ergotron LX Dual
Higher ratedRanked #1 in Best Dual Monitor Arms
Ergotron LX Dual
$330

The LX Dual is the best-overall pick. Industry-standard against which every other dual arm is compared — Ergotron's Constant Force spring and 10-year warranty are unmatched. Best for office workers and desktop power users who'll set and forget for 10+ years.

Strengths
  • Constant Force spring tech holds position perfectly across thousands of adjustments
  • 10-year warranty — industry's longest
  • Side-by-side arm supports two displays up to 27"
Watch-outs
  • $330 is the most expensive non-HX pick
  • 27" / 20-lb max per monitor — won't fit modern 32" ultrawides
  • Installation is heavier than budget arms (more parts)
HUANUO Dual Monitor Arm
Ranked #5 in Best Dual Monitor Arms
HUANUO Dual Monitor Arm
$50

The HUANUO Dual is the budget 32" pick. Cheap gas-spring arm that handles bigger displays than the Amazon Basics — useful for budget buyers with 32" monitors. Trade-off is long-term tension loss vs Ergotron's constant force.

Strengths
  • Gas-spring mechanism for fluid height adjustment
  • Heavy-duty C-clamp + grommet mount options
  • Cable management clips along the arm
Watch-outs
  • Gas-spring loses tension over years (replaceable but adds maintenance)
  • Brand support and warranty service trail Ergotron's
  • Plastic accents feel less premium than the LX Dual
