Most arms can’t hold a real ultrawide
A 49-inch curved panel is heavy and has a lot of leverage. Put it on a mid-range arm and you get sag, a slow droop over the day, and a bounce every time you type hard. The HX is engineered for exactly this weight class. Before you buy the monitor, price the arm on Amazon.

Fingertip repositioning
Ergotron’s Constant-Force lift is tuned so a heavy display feels weightless through its range and stays exactly where you leave it — no knobs. For a shared or hot-desk setup where people reposition constantly, that’s the feature. Setup-obsessives buy the HX on Amazon.

Mounting and cables
Use the C-clamp on a solid desk; check thickness limits for thick tops. Cables run through the arm for a clean look. Confirm your monitor’s weight and VESA against the spec on the Amazon listing.
