What the LUOM OZC4-1 captures

The LUOM OZC4-1 is a USB 3.0 video capture device built for gamers and streamers who want to record or broadcast gameplay. It accepts an HDMI source at up to 4K 60fps and encodes a 1080p 60fps stream for the host computer. The aluminium dongle also provides a loop-out that passes 4K 30fps or 1080p 120Hz to a monitor so play remains smooth while recording.

What the bundled connections change

A 3.5 mm microphone input and headphone output sit on the same housing, letting you mix live commentary with game audio without a separate mixer. The single USB 3.0 link carries both video and audio to the PC, so no external power brick is required. HDMI 2.0 pass-through keeps the signal path short, reducing the delay between controller input and on-screen action.

Installing and common pitfalls

Plug the device into a USB 3.0 port, connect the source to the HDMI input, and select the LUOM OZC4-1 in OBS, VLC, Amcap or any UVC-compatible application — no driver download is needed on Windows 10 or 11, Mac OS or Linux. If the capture window stays black, verify that the source is not sending a protected HDCP signal and that the USB port is actually running at 3.0 speeds rather than falling back to 2.0.

Questions about this item

Will the HDMI 2.0 pass-through port need replacement after heavy daily use?

The HDMI 2.0 pass-through port is built into the aluminium-alloy body and has no moving parts, so it does not wear out under normal daily use.

What resolution limit appears first when capturing continuously at high frame rates?

Continuous capture is limited to 1080p at 60 fps; 4K input is accepted but recording tops out at Full HD 60 fps.

How hot or noisy does the aluminium body get during all-day streaming sessions?

The fanless aluminium housing stays silent and only becomes warm to the touch during extended 4K pass-through or 1080p 60 fps capture.
