The Magewell USB Capture HDMI Plus adds the two features streamers and presenters ask for most: a zero-latency HDMI loop-through output for local monitoring, and 3.5mm audio jacks for connecting a headset or external microphone.
If you are a gamer, the loop-through lets you play on your TV with zero delay while OBS captures every frame. If you are a presenter, you can see your slides on the room projector while your webinar software captures the feed.
The built-in FPGA chip processes everything onboard, keeping your CPU free for encoding.
