Using the Epiphan AV.io 4K Video Grabber is easy. First, connect the HDMI input connector to your video source. Then, plug the USB 3.0 B - Type output connector into your computer. The device will be auto - detected by your operating system (Windows 8.1, Windows 10, Mac OS X 10.10 and up, or Linux with kernel 3.5.0 or higher). Once it's detected, you can start capturing video in high - quality 4K or other supported resolutions. When using it, make sure to use an Intel USB host controller for the best performance. As for maintenance, keep it in a dry and clean place. Don't expose it to extreme temperatures or moisture. If there's dust on it, you can use a soft, dry cloth to clean it gently. Also, be careful when handling the cables to avoid any damage.
