Monitor fit
BenQ lists 17- to 35-inch screens weighing 2 to 20 kg on each arm, with 75 or 100 mm VESA plates. BenQ says larger monitors may limit the adjustment range.

What works. What doesn't.
Desk fit
It fits desks 17 to 50 mm thick without the included reinforcement plates and 12 to 45 mm with them, by clamp or grommet.
Adjustment
WIRED says the dual version has no pole: both arms mount in the clamp itself, which makes a symmetrical two-screen layout easier.
Build and support
WIRED rates the Ergo Arm its best overall monitor arm but calls the three-year warranty short for the price.
