Issue: You have either SDI or NDI sources coming into the Media DS Inputs but no image shows; the input only displays black. The audio from the sources is present though.
1) First ensure you are on the latest available software update for the MediaDS. Once the update is installed, be sure to reboot the system and launch the software again. https://www.newtek.com/downloads/
2. If the issue remains after updating the software, install the specific Intel driver linked below. Reboot the system and video should now appear in the Input source previews. https://downloadcenter-origin.intel.com/download/27892/Intel-Graphics-Driver-for-Windows-10
