A monitor arm lifts your screen off its stand so you can raise it to eye level, push it back for depth, and reclaim the desk space underneath. The two things that matter are that it fits your monitor's weight and VESA mount, and that its motion holds position without drifting. Here is the pick that comes up most, plus a budget alternative.

For a big ultrawide or a heavier display, check the arm's stated weight and size limits and step up to a heavy-duty model.
What should you look for in monitor arm?
A few things separate a good monitor arm from a frustrating one: weight & size rating, vesa compatibility, motion that holds, and cable management & clamp. Weigh these before you buy.
- Weight & size rating: match the arm to your monitor's weight and screen size, with headroom to spare.
- VESA compatibility: your monitor needs VESA mount holes (75x75 or 100x100); check before buying.
- Motion that holds: a good gas-spring or constant-force arm stays put; cheap ones sag over time.
- Cable management & clamp: tidy channels and a solid desk clamp keep the setup clean and stable.

Budget pick
HUANUO Single Monitor Mount
A popular value arm that covers the basics: gas-spring height adjustment, tilt and swivel, and VESA mounting. It is not as buttery or long-lived as the Ergotron, but it is a fraction of the price and fine for a lighter monitor.

For a big ultrawide or a heavier display, check the arm's stated weight and size limits and step up to a heavy-duty model so it holds position without drooping.
Bottom line: the Ergotron LX is the buy-it-for-life pick that actually holds position; the HUANUO is a solid budget choice for a lighter monitor, and go heavy-duty for a big ultrawide.
