The Magewell USB Capture HDMI 4K Plus connects to your computer over a USB interface and lets you capture up to a 4K DCI resolution signal (4096 x 2160) with embedded audio via an HDMI 2.0 input. It allows you to capture from cameras, game consoles, and various other devices directly to your Windows, Mac, Linux, or Chrome computer. It also features an HDMI loop-through for local monitoring and 3.5mm audio input and output for capturing external audio and extracting embedded audio.
The device also offers a variety of processing and other features, including resolution scaling and deinterlacing. It also has a status LED for displaying the status of the input, including idle, input signal locked, memory failed, or FPGA configuration.
*Please use the included Magewell USB 3.0 cable, which is a custom accessory. Using any other similar cable might cause capture problems and even damage the capture device.
