An ultrawide arm is a trust exercise: a wide, heavy, curved panel floats on one joint, and the figures that matter are screen size and capacity. The best monitor arm for ultrawide here is the VIVO STAND-V101VW, rated to 49 inches and 44 lb, the pairing that covers the largest panels made. The ARES WING follows as the documented white arm for 17 to 40 inch screens, spring rated through 25,000+ cycles, the PUTORSEN stacks two 44 lb arms for dual-screen desks, and the aluminum VIVO G1 closes on build. We compared stated sizes, capacities and mounting, using only what each listing publishes.

Detailed Review
PUTORSEN lists a dual arm for 17 to 49 in screens with 44 lb per-arm capacity, a 19.69 in center pole for vertical stacking and gas spring arms of aluminum and steel. The bullets state +50 to -20 degree tilt, ±90 degree swivel and 360 degree rotation, with an included Allen wrench for tuning the arms to the monitor weight; the spec table instead lists a 20 degree maximum tilt, and we trust the bullets. The spec table states a 10-year warranty and an 8.3 kg item weight.
Who it's for: someone stacking two large or ultrawide screens on a narrow desk who wants the longest stated warranty here. Who should skip it: anyone who needs a stated desk-thickness range or a side-by-side layout, since the listing states neither.

How we scored them
Scores weigh support performance, build, value, safety and warranty. The V101VW leads on the two headline figures for the format. The ARES WING follows on documentation, the only spring endurance figure here, the PUTORSEN on its unique stacked layout, and the G1 trails on the figures its title does not state. No listing states a warranty term or certification, so those scores sit at zero.
| Product | Office Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| ARES WING 17-40 Heavy Duty | 9.4 | 29 | 18 | 15 | n/a | 0 |
Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score. Safety counts only for powered gear or where the listing states safety features; where it does not apply, the score is taken over the remaining 90 points.
How to choose the best monitor arm for ultrawide
Capacity headroom is the whole game
Weigh your panel, then buy the arm whose stated capacity clears it with room to spare: a spring at its limit sags and drifts, a spring in its middle holds a pose for years. The 44 lb class here covers the 49 inch flagships; the 26.4 lb ARES covers the 34 to 40 inch mainstream. Screen size alone does not pick the arm, weight does, and the two figures travel together in the listings above. The neighbouring single arm monitor mount roundup covers standard screens.
Clamp, grommet, and the desk between
Mounting decides what your desk must survive. Clamps grip an edge and forgive; grommets need a hole and hold like joinery. The ARES WING ships both, which is why it suits desks still being decided. Cable management, integrated on the ARES, is the difference between a floating screen and a floating screen with a tail. Decide the mount before the arm, and the arm will fit the room you actually have.
