How to use DVI2USB 3.0 for video capture on WindowsThis article explains how to capture live streaming video to your PC and record it using DVI2USB 3.0– a video grabber solution specially designed for capturing signal from a VGA, DVI or HDMI™ (non HDCP) video source. Standalone video grabbers are a portable alternative to streaming capture cards. Epiphan’s portable video grabbers provide live capture through a USB connection to the PC or laptop and do not require additional power supply. In this example the DVI2USB 3.0 USB 3 frame grabber is used.
