With a 4-channel HDMI splitter, I can feed an HDMI into the monitor; an HDMI-HDMI-USB converter; and an HDMI to HDMI VGA converter (for the headphone jack as my monitor doesn't have audio out but I need to use a different adapter setting as this unit also inverts left and right audio). Audio and video appear in real time on all devices and I can use VLC (Open Source Media Player) to convert USB audio/video to MP4 recordings.
