The Best Monitor Arm
Researched by Johnny Alto · last updated July 27, 2026
Short answer: The best monitor arm is the Ergotron LX. The arm reviewers and desk-setup communities recommend above all others. The main things to weigh are weight & size rating, vesa compatibility, motion that holds, and cable management & clamp.
Ergotron LX
The arm reviewers and desk-setup communities recommend above all others. Its patented constant-force mechanism moves smoothly and, crucially, stays exactly where you put it instead of sagging over time, which is where cheaper arms fail. It has a wide height and depth range, tidy cable management, and Ergotron's long warranty and build quality. It handles most monitors up to around 34 inches and 25 pounds.

Representative image.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.
How do the best options for monitor arm compare?
| Pick | Product | Why it makes the list |
|---|---|---|
| Top pick | Ergotron LX | The arm reviewers and desk-setup communities recommend above all others. |
| 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. |
| Ultrawide or heavy screens | a heavy-duty or aluminum gas-spring arm | 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. |
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.
