@richardc1983, here are some of the names of the samples that I tested earlier when I had some issues with my receiver which is not accepting 10bit 422 signal.
Remember to give us all relevant information regarding each sample: Ex. (2160p 420 10bit (BT.709) 30fps 51mb), (2160p 420 10bit (BT.2020) 30fps 50mbit) etc. Use Mediainfo if you need to
