After the latest round of PMS updates, using my WD My Cloud (Gen 2), I can stream 4K HDR files (60GB or so) 100% fine to my Vizio Smartcast or Xbox One (no HDR for the Xbox).
Figured this would be useful information for those figuring out which NAS to buy. You may not need an expensive one if you are okay with limited features otherwise!
- To clarify, I modded the My Cloud so I could install Plex on it, using this guide: https://community.wd.com/t/wd-mycloud-gen2-enable-apps-install-tab-apps/177885
