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.

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 LX Dual

The LX Dual is the build-quality benchmark in this group, more refined and stable than the budget VIVO STAND-V002 and Monoprice Workstream Dual, 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, and the HUANUO DS12 undercuts it on price while approaching its metal build.

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.
