Looks like the current version and last version of PMS, ignore direct play options/maximum quality options and tries to transcode 4k HDR content to 1080p on a couple of 4k Samsung TVs I have. Let me know if you needs logs.
I looked at logs and I don’t think what I wrote in the subject of this post is accurate. Sorry about that! However, still have issues direct playing 4k HEVC HDR files, that I have previously played without issue.
