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 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
  • — Each arm independently lifts, tilts, pans, and rotates two displays up to 27 inches
  • — 25 inches of extension and 360-degree rotation for flexible positioning
  • — Industry-leading 10-year warranty covering the tension system
Watch-outs
  • — Limited vertical range can be short for very tall standing-desk users
  • — Premium price relative to budget steel-pole stands
  • — Side-by-side layout suits up to 27-inch monitors, not large ultrawides

Ranked #2 in Best Dual Monitor Arms
Vari Dual-Monitor Arm
2 sourcesall derived$299as of Oct 17

The Vari Dual-Monitor Arm is a clamp-on, pole-mounted arm for two monitors of up to 27 inches, with each arm rated to 19.8 lb. Tom's Guide named it the best monitor arm for two screens, citing its strong build and sleek design. It also found the setup slow and the clamp limited to desks about 2.25 inches thick. The Gadgeteer found it easy to install and very adjustable, and it kept the monitors secure on a moving standing desk. It suits people pairing two mid-size monitors with a standing desk. Those with thick or shallow desks, or larger screens, should look elsewhere.

Strengths
  • — Holds two monitors up to 27 in; each arm takes up to 19.8 lb
  • — Tom's Guide picked it as its best dual-monitor arm for strong, sleek build
  • — Arms extend, swivel and tilt, making it easy to reposition screens
Watch-outs
  • — The clamp only fits desks about 2.25 in thick or thinner
  • — Tom's Guide found setup took longer than average
  • — Needs plenty of clearance behind the desk; shallow desks feel cramped

How they stack up

Ergotron LX Dual

The LX Dual is the build-quality benchmark in this group, more refined and stable than the budget VIVO STAND-V002, and rivaled only by its heavier-duty sibling, the Ergotron HX Dual. Where the HX Dual handles heavier and larger monitors, the LX Dual is the better fit for standard dual-27-inch setups.

Vari Dual-Monitor Arm

Like the Ergotron LX Dual, the Vari is aimed at two monitors of up to 27 inches. It carries a five-year warranty, according to Tom's Guide, compared with the three-year warranty noted for the MSI MAG MT201D. At $299 it sits at the opposite end of the price range from the budget VIVO STAND-V002, and its clamp is limited to desks about 2.25 inches thick.
