What is the best monitor arm for an ultrawide monitor?

Best pick for most ultrawide setups: Ergotron HX. It’s the safest recommendation if you’re mounting a large ultrawide, super-ultrawide, or heavy widescreen and want smoother adjustment with less wobble.

If you’re trying to spend less, look at VIVO Heavy Duty—it’s a strong budget-oriented pick for ultrawides up to 49 inches. For very large screens, ULTRARM Heavy Duty is worth considering because it lists support for ultrawides up to 57 inches and up to 44 lb. If your monitor is smaller/lighter and you want a polished everyday arm, Herman Miller Jarvis Single Monitor Arm is a good general-purpose option, but I’d verify your exact monitor weight and VESA pattern before choosing it for a big ultrawide.

Before buying any arm, check three things: your monitor’s weight without stand, VESA mount pattern, and whether your desk can handle the clamp or grommet mount securely.
