What reviewers say

Sourced tester consensus for each — the "what people who used it think" layer, not just specs.

Ergotron LX Pro Desk Monitor Arm (Matte Black)

Two whitelisted hands-on testers, Wirecutter and PCWorld, both name the Ergotron LX Pro a top single-monitor arm pick, praising its easy, tool-light setup and build/motion quality that matches pricier arms; PCWorld calls it great value at its ~$200 price. Wirecutter measured setup at about 20 minutes but flags a tricky recessed tension screw and fiddly cable management; PCWorld's only knock is a lower max weight (22 lb) than the older LX (25 lb). Verdict: buy. (2 sourced reviews, 2 lab-tested.)

Praised: Easy, tool-light installation; Smoothness of motion, range, and sturdiness match pricier top-pick arms; Great value and build quality competitive with pricier arms at the ~$200 price.

Flagged: Recessed tension screw is tricky to reach and adjust; easier with a helper; Cable management is functional but cheap-feeling and fiddly; Lower max weight (22 lb) than the older LX (25 lb).

Jarvis Single Monitor Arm

Only one whitelisted tester, Wirecutter, hands-on reviewed this arm (now sold as the Herman Miller Jarvis after Fully was folded into Herman Miller) and names it their top monitor-arm pick after assessing 25 models. They praise its smooth, wide range of motion, sturdiness, and slimmest-in-test base, but flag noticeable wobble when extended, fiddly cheap-feeling cable management, and a setup that is not the easiest and hard to do solo. (1 sourced review, 1 lab-tested.)

Praised: Smoothest and widest range of motion in the test group; Sturdy build with the slimmest base of any arm tested; Easy to adjust plus a long warranty.

Flagged: Monitor wobbles when extended far forward or to the side; Decent but fiddly, cheap-feeling cable management; Not the easiest to set up, and hard to do solo.
