RealTek HDMI-USB3-4K capture dongle
This USB 3.0 adapter captures HDMI video up to 4K at 30 Hz and 1080P at 60 Hz. It works with Windows, Linux and OS X without installing drivers. The dongle handles video and audio processing internally and supports UVC and UAC standards for broad software compatibility.
Plug-and-play UVC and YUV 422 output
No external drivers are required because the device follows UVC video capture and UAC audio standards. It automatically detects the input format and adjusts to the set output size and frame rate. YUV 422 video output is provided for compatible recording or streaming applications.
HDMI 4K 30 Hz input limit and USB 3.0 bandwidth
The adapter accepts HDMI 4K signals only at 30 Hz, while 1080P capture reaches 60 Hz. USB 3.0 interface bandwidth constrains the maximum throughput, so higher frame rates at 4K are not supported. Single-channel HDMI capture is the only input mode available.
