Ranked #5 in Best Dual Monitor Arms

HUANUO Dual Monitor Arm

4.3

$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
