What weight and size can these arms actually hold?
Reviewer consensus
Most budget spring arms (HUANUO FlowLift, VIVO V002) are rated around 19.8–22 lbs per arm and target 13–32" screens. HUANUO's heavier 13–40" mount is rated higher at roughly 26.4 lbs per arm, and Ergotron's stacking LX supports up to 22 lbs per arm on 40" screens. Always check your monitor's actual weight against the arm's per-arm rating, not just the maximum size.
