Compact 4K@60Hz HDMI Capture for Streamers

The Jansicotek OZC3B accepts a single HDMI input up to 4K at 60 Hz and passes a 1080p 60 fps signal to a host over USB 3.0. It works with Windows 7 through 10, Linux and macOS without a driver in most cases, making it suitable for creators who move between laptops and desktops. The dongle also provides an HDMI loop-out so the source display stays active while recording.

Thermals Noise and Power in Normal Use

The unit draws bus power from the USB 3.0 connection, so no external adapter is required during typical streaming sessions. Its aluminium shell acts as a passive heatsink, keeping surface temperatures low even after hours of continuous capture. No fan is present, so operation stays silent in quiet studio environments.

Bundled Cable and Manual Enable Immediate Setup

A 10 Gbps USB 3.0 cable is included, removing the need to source a compliant lead separately. The printed manual walks through the UAC and UVC device selection in OBS, Potplayer or VLC so the 48 kHz PCM audio path is recognised at first launch. Firmware upgrades are delivered over the same USB link, extending compatibility as new host OS versions appear.

Questions about this item

How do I install the Jansicotek OZC3B and which step is often missed?

Connect the HDMI source to the input, link the loop-out to a display if needed, plug the USB 3.0 cable into the PC, and select the device in OBS or streaming software; the step often missed is enabling the 48 KHz PCM audio input in the OS sound panel.

What maintenance or replacement will the Jansicotek OZC3B need later?

No scheduled maintenance is required; keep the USB 3.0 cable and HDMI ports free of dust, and apply any future firmware upgrades via the supplied utility to maintain compatibility with Windows 10, Linux or Mac OS.

What limit appears first during a long streaming session with the Jansicotek OZC3B?

The 1080P 60 FPS capture ceiling is reached before the 4K passthrough, so extended broadcasts stay at 1080P 60 FPS while the HDMI loop-out continues passing the source signal unchanged.
