HUANUO Single Monitor Arm vs Ergotron LX Monitor Arm

Both are real monitor arm options from our monitor arms guide. Specs below are taken from each product's own listing — we don't run benchmarks or invent performance numbers.

HUANUO Single Monitor Arm

Full-motion arm for 13–34 inch monitors up to about 20lbs, with both C-clamp and grommet base options included.

Specs

Fits 13–34 inch monitors
Holds up to 19.8 lbs
Full-motion swivel/tilt/rotate
VESA 75×75 and 100×100mm
C-clamp and grommet base included

✓ Best for

Reclaiming desk space on a budget — both mounting options are in the box, so it fits most desks without extra purchases.

⚠ The tradeoff

The ~20 lb capacity rules out heavy ultrawides and large VA panels. Check your monitor's actual weight, not just its size.

Ergotron LX Monitor Arm

Premium single-monitor desk mount for screens up to 34 inches and 25lbs, well known for long-term build quality.

Specs

Fits up to 34 inch monitors
7–25 lbs weight range
Constant Force gas spring
VESA 75×75 and 100×100mm
Polished aluminium construction
10-year warranty

✓ Best for

Frequent repositioning — the gas spring holds position properly and adjusts with one hand, which cheaper arms often don't.

⚠ The tradeoff

Costs several times a budget arm, and there's a *minimum* 7 lb weight — very light monitors can't tension the spring correctly.
