Magewell USB Capture HDMI 4K Plus – Single-Channel 4K USB Capture Device

Product Overview

The Magewell USB Capture HDMI 4K Plus is a single-channel USB 3.0 capture device designed for AV integrators, IT managers, and production teams who need to bring 4K HDMI signals into software applications without installing a capture card. Supporting input resolutions up to 4096x2160 with HDMI 2.0 loop-through, it is purpose-built for conference room systems, video conferencing platforms, and content capture workflows. As a UVC-compliant plug-and-play USB capture device, it works across Windows, Mac, Linux, and Chrome OS with no driver installation required. Long-tail compatibility with Zoom Rooms, Microsoft Teams Rooms, OBS Studio, and XSplit makes it a practical choice for commercial AV deployments of any scale.

Product Description

The USB Capture HDMI 4K Plus (SKU: 32090) connects directly to any USB 3.0 port and presents itself to the host system as a standard UVC video capture device, eliminating the need for proprietary drivers or software installation. Its 600MHz HDMI receiver handles input and loop-through resolutions up to 4096x2160 60fps 4:4:4, making it compatible with the latest 4K sources including game consoles, cameras, and presentation systems. Capture output is scaled to resolutions supported by the host application — up to 3840x2160p30 or 1920x1080p90 — giving AV designers flexibility to match platform requirements without upstream signal conversion.

The integrated 3.5mm audio jack functions as both a microphone input and a headphone output, allowing the device to act as a USB audio card in addition to a video capture interface. This is particularly useful in conference room and huddle room installations where a single USB device handles both camera signal capture and audio monitoring. On-board signal processing supports video cropping, up/down scaling, deinterlacing, aspect ratio conversion, color format conversion, frame rate conversion, and flip/mirror — all handled in hardware with approximately 640 megapixels per second of processing bandwidth. The status LED provides at-a-glance feedback on signal lock state, memory status, and power condition, supporting efficient troubleshooting in commercial meeting spaces. Magewell backs this device with a three-year warranty and provides Windows, Linux, and Mac SDKs for custom integration work.

Technical Specifications

Frequently Asked Questions

Does the USB Capture HDMI 4K Plus require driver installation?
No. The device is UVC (USB Video Class) compliant and is recognized as a standard video capture device by Windows, Mac, Linux, and Chrome OS without installing drivers. On Windows, it also presents as a WDM audio device.

What is the maximum capture resolution and frame rate?
The device captures up to 3840x2160 at 30fps or 1920x1080 at 90fps. The HDMI input and loop-through both support up to 4096x2160 60fps 4:4:4, but captured output resolution is limited by USB 3.0 bandwidth and the host application's settings.

Is the HDMI loop-through active or passive?
The loop-through is active. The 600MHz HDMI receiver relays the input signal to a connected display at the full source resolution (up to 4096x2160), independent of what the host computer is capturing.

Which video conferencing platforms are compatible?
The device is compatible with Zoom Rooms, Microsoft Teams, Microsoft Teams Rooms, Skype for Business, Google Hangouts, and GoToMeeting, as well as any software that supports DirectShow (Windows), V4L2 (Linux), or AVCaptureSession (macOS).

Can this device be used for 24/7 continuous operation in a commercial installation?
Yes. The USB Capture HDMI 4K Plus is rated for continuous 24-hour, 7-day-per-week operation, making it appropriate for permanent conference room and broadcast studio installations.

Does it support custom integration via SDK?
Yes. The MWCapture SDK supports Windows (DirectShow, WASAPI), Linux (V4L2, ALSA), and macOS (AVCaptureSession, AudioUnit), enabling integrators to build custom capture applications or integrate with control systems.

What is the warranty period?
Magewell provides a 3-year manufacturer warranty on the USB Capture HDMI 4K Plus. For warranty claims or technical support, contact Creation Networks or open a support ticket directly through Magewell.
