RGBlink MSP 331U Gen2 HDMI 2.0 4K60 Capture Card

The RGBlink MSP 331U Gen2 HDMI 2.0 4K60 Capture Card converts high-resolution HDMI sources into USB video for recording, streaming, conferencing, and production software. It accepts HDMI signals through 4096 x 2160 at 60 Hz, provides an HDMI loop output, and delivers USB capture resolutions up to 3840 x 2160 at 60 Hz depending on the selected capture format.

Built for cameras, computers, game consoles, presentation systems, and live production equipment, the MSP 331U Gen2 combines HDMI 2.0 connectivity with a 5 Gbps USB 3.2 interface. Its plug-and-play UVC/UAC design makes it useful for 4K HDMI capture, live streaming workflows, video conferencing, and portable production systems without proprietary capture drivers.

The unit supports HDR signals, HDCP 2.3, HDMI audio mixing with an external line input, and a dedicated 3.5mm analog audio output. Multiple USB capture formats provide flexibility for different bandwidth and resolution requirements, while a dynamic status light displays signal conditions in real time. Compatibility includes Windows, macOS, Linux, and a range of DirectShow, V4L2, and AVCaptureSession applications.
