34-inch ultrawide monitor arm: reach and leverage
A 34" ultrawide isn't especially heavy (about 5–8 kg), but it's wide — so the arm's reach and the leverage on the mount matter as much as the raw weight rating.
What to look for
100 × 100 VESA is standard here. A good gas-spring arm holds a 34" ultrawide, but check two things: enough reach to centre a wide panel, and a rating with margin because the width puts more torque on the clamp. Curved 34" OLEDs (e.g. QD-OLED) are on the lighter side but still benefit from a sturdy arm.

FAQ
Do I need a special arm for a 34-inch ultrawide?
Not special, but sturdy. Most 34" ultrawides are 5-8 kg on 100x100 VESA — a solid single gas-spring arm with enough reach works. The width adds leverage, so favour margin over a bare-minimum rating.
Will one arm hold a 34-inch ultrawide steady?
Yes, a single arm rated with margin holds it. If you get drift or bounce, the arm is under-rated for the leverage — step up a class.
