About

A corporate/medical/broadcast-grade Magewell unit with native V4L2 (Linux) and DirectShow (Windows) SDK integration — deliberately caps 4K capture at 30fps to never risk dropping a frame over its USB 3.0 link.

HDMI version: 2.0
Max resolution: 4096x2160@30Hz
Requires DisplayLink driver: No

Ports: 1× HDMI (entrada, compatible DVI-D), 1× HDMI (salida), 1× USB 3.0, 1× Audio 3.5mm mic in and 1× Audio 3.5mm headphone out

Confirmed with

Notebook (generic)
The internal processing ceiling of roughly 640 Megapixels/second and the physical USB 3.0 bus force a strict, non-negotiable 30fps cap when capturing in native 4K color spaces — reaching 60fps requires dropping to 2560x1440.
