Using the Epiphan AV.io HD+ is a breeze. First, connect it to your device with the USB cable and then link it to an HDMI source. You can also connect an audio source if you want. The device works right away without needing any driver installation. When switching between different sources, the automatic scaling feature will adjust the image for you. Just make sure your operating system meets the requirements - Windows 10 and up, Mac OS X 10.10 and up, or a Linux distribution with kernel 3.5.0 or higher. Remember, it can't capture from sources protected by HDCP. For maintenance, keep it in a clean and dry place. Since it's lightweight and durable, it can withstand long - term use, but try not to expose it to extreme conditions. The LED on the device will show you its status, like power, readiness, or if it's in operation.
