The issue is not with the Plex server but an App on the TV. It is limited to what it can or can not do. And subtitles seem to require transcoding. Not very smart app. Even new 453D would not be able to transcode 4K fast enough. You may need 72XT or 882 series for that or even TS-473 with additional GPU fro this.But I would recommend to experiment and find out which formats your TV app will support. There might be some of the 4K it does.I would still pick a 53B series in your case.I hope this helps.
