USB Capture HDMI Plus overview

The Magewell USB Capture HDMI Plus is a video capturing device built for streamers and creators who need to bring an external HDMI source into a computer over USB. It accepts an HDMI signal and provides a loop-through output so the same feed can reach a local display without extra splitters.

Loop-through and audio I/O

A built-in loop-through HDMI port passes the incoming signal onward, letting you monitor or record simultaneously. Audio can be injected through a 3.5 mm microphone jack, and embedded HDMI audio is extracted to a separate 3.5 mm headphones jack for independent monitoring or capture.

Compatibility check before ordering

Verify that your source outputs an HDMI signal the device can accept and that your computer has a free USB port with enough bandwidth for the capture stream. Confirm the 3.5 mm jacks match your microphone and headphone plugs, and ensure your recording or streaming software recognises UVC-class video devices.

Questions about this item

Does the Magewell USB Capture HDMI Plus need a separate power supply or does it draw power from the USB connection?

The device is bus-powered over USB so no external power adapter is required; simply connect it to a free USB port and it will start up automatically.

Which cables and ports must be connected first to get a clean signal through the loop-through HDMI output?

Plug the source into the HDMI input, then run a second HDMI cable from the loop-through output to your display; the USB link to the PC can be attached last.

If the 3.5 mm microphone or headphone jack stops passing audio, can the port be repaired or must the whole unit be replaced?

The audio jacks are soldered to the main board so a failed jack normally means sending the unit in for service rather than a simple user swap.
