Higher ratedRanked #2 in Best Dual Monitor Arms

Ergotron HX Dual

4.6

$539as of Jun 7

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
— Handles substantially more weight per arm than the LX Dual

Watch-outs

— Most expensive arm in this group by a wide margin
— Reviewers note slight wiggle between the monitor mounts and arms
— Vertical stroke may be short for very tall users

Ranked #3 in Best Dual Monitor Arms

HUANUO DS12 Dual Monitor Arm

4.4

$139.99as of Jun 7

The HUANUO DS12 is the value sweet spot: a near-all-metal dual arm with gas springs rated to 26.4 lbs per side, enough for 32-inch and 34-inch ultrawide monitors, plus built-in USB ports, for roughly a third of an Ergotron's price. PCWorld names it the best mid-range dual arm, and it carries a strong 4.6-star Amazon rating. Setup is fiddly and the springs need tuning for light monitors, but for metal build and capacity per dollar it is the standout middle option.

Strengths

— Almost entirely metal construction, rare at this price
— Gas springs lift up to 26.4 lbs per arm, enough for 32-inch and 34-inch ultrawides
— Built-in USB ports for convenient charging and data

Watch-outs

— Fiddly setup with two clamps and roughly a dozen screws
— Gas springs need tuning to reduce force with lighter 24-27 inch monitors
— Reviewers note it can settle into odd positions until micro-adjusted

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, HUANUO DS12, Monoprice Workstream Dual, and VIVO STAND-V002, and is overkill for the standard dual-27-inch setups those arms target.

HUANUO DS12 Dual Monitor Arm

The HUANUO DS12 is the value pick that approaches Ergotron's metal build for far less money: its near-all-metal arms and 26.4-lb capacity rival the heavier-duty Ergotron HX Dual for large monitors, while undercutting the Ergotron LX Dual on price. It is a clear step up in materials from the steel-pole VIVO STAND-V002, and offers more capacity and USB ports than the gas-spring Monoprice Workstream Dual.
