Review on DIGITNOW HDMI Capture Dongle Adapter Card - Full HD 1080p 60FPS Live Streaming Game Capture 🎮 Video Grabber for PS4 Xbox One 360 - HDMI to USB 3.0 - Drive-Free Compatible with Linux/Mac OS/Windows10/7/XP by Troy Boren

I work at church with an old Mac. We only have two Thunderbolt ports and the Black Magic Mini Recorder connects to the Thunderbolt port. This caused a problem as we needed both ports for two separate displays. Because the USB connection makes it possible to save both displays and still keep the transmission from the camera. Works well with ProPresenter, OBS and Facebook Live directly. worth your money.
