4x1 HDMI capture and switch

The LUOM OZC7 combines a four-input HDMI switcher with a USB 3.0 capture engine. It accepts four HDMI sources and a microphone, then routes a single programme feed to the USB port for recording or streaming while mirroring the same signal to an HDMI loop-out. Driver-free operation lets it work with any UVC-compatible application on Windows, macOS or Linux.

4K pass-through and 1080p60 capture

Each HDMI input supports 4K at 30 Hz pass-through, so the local display sees the full resolution. The USB 3.0 capture path tops out at 1080p at 60 fps, meaning 4K sources are downscaled for the recording or stream. Four sources can be connected simultaneously and switched without mutual interference, but the device cannot capture more than one input at a time.

Silent passively cooled operation

The aluminium enclosure dissipates heat without a fan, so the unit runs silently during long sessions. Power is drawn entirely from the USB 3.0 bus, eliminating the need for an external adapter. Typical draw stays within the USB 3.0 specification, keeping the host port within its current budget.

Questions about this item

Will the LUOM OZC7 work alongside my older HDMI 1.4 sources and still pass 4K@30Hz through its loop-out?

Yes — the unit accepts four HDMI 1.4 inputs up to 4K@30Hz and its HDMI loop-out mirrors that same 4K@30Hz signal, so legacy sources stay compatible.

How do I confirm the capture is running at 1080p 60 fps over USB 3.0 after I plug it in?

Open your streaming software, check the video properties — the device should report 1080@60fps and the LED indicator on the unit will be lit.

Does the box include cables for both USB-A and USB-C hosts, or do I need to buy one separately?

The package supplies a USB 3.0-to-USB 3.0 cable and a USB 3.0-to-Type-C cable, plus an IR remote and manual — no extra cable purchase required.
