Best Monitor Arms

What separates the best monitor arms on this page?

Three arms, three different jobs. The Ergotron LX Pro Monitor Arm scores 8.5 and carries a 10-year warranty. It holds monitors up to 34 in and 4–22 lb, and PCWorld named it Best Overall single-monitor arm after hands-on testing, calling it "easy to set up, looks nice, works well in day-to-day use." It lists at $209 MSRP (PCWorld).

The Fully Jarvis Single Monitor Arm scores 7.5 at $131.25, marked down from $175 at the Herman Miller Store. Its 15-year warranty is the longest of any product in this ranking, and it covers 13"–32" monitors at 2.2–19.8 lb. The VIVO Dual Monitor Desk Mount scores 7.4 at $39.99 and holds two 13"–30" monitors up to 22 lb each, with a 3-year warranty.

So the split is warranty length, monitor count, and price. One arm for one screen with a decade of coverage, one with fifteen years, one that carries two screens for less than either single arm.

What should you check before buying a monitor arm?

Start with weight and size, because that is where returns happen. Check your monitor's weight against the arm's range: 4–22 lb on the Ergotron, 2.2–19.8 lb on the Jarvis, 22 lb per screen on the VIVO. Then check VESA pattern — all three support 75x75 and 100x100.

Warranty is the next filter. The scoring criteria weight durability and warranty at 15 points, and the gap here is real: 15 years, 10 years, 3 years.

Two practical notes from the listings. Ergotron sells several similar LX/LX Pro SKUs, so confirm the exact spec before buying. And the Jarvis arm's Amazon color listings are currently unavailable, so the Herman Miller Store is the direct link.
