DVDO USB3.0-Capture 4K HDMI to USB 3.0 Capture Dongle with HDMI Loop Out

This is the dongle that puts a camera, a console or a second computer into a video call or a stream. The HDMI input accepts up to 4K2K at 60 Hz, and the USB output presents the picture to the host at up to 1080p60, downscaling automatically when the source is 4K. Below 1080p the output matches the input. The dongle draws its power from the same USB port it captures over.

An HDMI loop output carries the full 4K60 4:4:4 signal on to a local monitor, so the operator sees the source at native resolution while the computer records a broadcast-friendly version. It appears as a standard capture device in Windows, Linux and macOS with no driver install, and works with VLC, OBS, XSplit, AmCap and other UVC-aware software. Over USB 3.0 the video is uncompressed YUY2; on a USB 2.0 port it falls back to MJPEG.
