Our Full Review
I put off buying a monitor arm for years because they all seemed like fidgety desk clutter. Then I got the Ergotron LX and realized I'd been ruining my neck for no reason. The difference in ergonomics is immediate and dramatic -- my 27-inch monitor is now at perfect eye level, tilted exactly how I want it, and I reclaimed about a square foot of desk space.
The build quality is in a completely different league from the $30 Amazon arms I'd been eyeing. The LX is mostly metal with a polished aluminum finish that matches my setup. The spring-loaded arm moves with one finger -- you push the monitor to where you want it and it stays. No tightening knobs, no sagging, no drift. After three months of daily repositioning, it holds position exactly as well as day one.
Installation took about 15 minutes. The desk clamp accommodates surfaces up to 2.4 inches thick, and there's a grommet mount option if you prefer. Cable management is built into the arm with removable clips that keep everything neat. The arm supports monitors up to 34 inches and 25 lbs, which covers virtually any single monitor you'd use.
The only real downside is the price. At $175, it's 3-4 times what budget arms cost. But the 10-year warranty, the zero-maintenance design, and the fact that it genuinely improves your daily posture make it a worthwhile investment. I've since bought a second one for my wife's desk -- that should tell you everything.
One tip: the tension adjustment for the spring is on a bolt underneath the elbow joint. Spend 5 minutes dialing it in for your monitor's weight and everything becomes perfectly balanced. Most negative reviews I've seen are from people who skipped this step.
How We Tested
Tested daily for 3 months with a 27-inch monitor (15 lbs). Tested tilt, swivel, and height adjustment range. Measured desk clamp footprint on various desk thicknesses. Compared spring tension and drift against two budget arms. Tested cable management with 3 cables routed through the arm.
Who Is This For?
Anyone who works at a computer for extended hours. Especially valuable for people with neck or upper back pain from looking down at a monitor. Content creators who need to reposition screens frequently. Not necessary if you're happy with your monitor's built-in stand and don't need the desk space.
Frequently Asked Questions
Will it hold my ultrawide monitor?+
It supports up to 34 inches and 25 lbs. Most 34-inch ultrawides are within that range. Check your monitor's weight -- some heavier ultrawides may need the Ergotron HX instead.
Does the clamp damage the desk?+
It comes with a protective pad for the clamp. On laminate and wood desks, I've seen zero marks after 3 months. On very thin IKEA-style desktops, use the grommet mount instead.
Can I use it with a laptop?+
Yes, with a VESA-compatible laptop tray (sold separately). Ergotron makes one, and there are third-party options that work fine.
