The short answer

Vari Dual-Monitor Arm is the only one of the two with a published score (4.0); Ergotron HX Dual has none, so this is not a close call so much as an unmeasured one. Vari Dual-Monitor Arm is best for: people pairing two monitors up to 27 inches with a standing desk who want a sturdy, adjustable arm. Read the strengths below before deciding.

Ergotron HX Dual
Ranked #5 in Best Dual Monitor Arms
Ergotron HX Dual
Unrated3 sources$539as of Oct 11

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
  • — Smooth, premium articulation with a 10-year warranty
  • — Built to reposition two 32-inch monitors with ease
Watch-outs
  • — Reviewers note slight wiggle between the monitor mounts and arms
  • — Vertical stroke may be short for very tall users

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

Derived means the reviewer published no score, so one was inferred from their written verdict. Everything else is a number the publisher printed. How we rank.

How they stack up

Ergotron HX Dual

The HX Dual is the heavy-duty step up from the Ergotron LX Dual, carrying far more weight per arm and handling larger monitors and ultrawides that would exceed the LX's rating. It is markedly pricier than the LX Dual and VIVO STAND-V002, and is overkill for the standard dual-27-inch setups those arms target.

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.
