The sizes of the 2160p files on a USB was too much for my 2018 LG TV to deal with. Smaller 2160p files (such as the TeamNegative1 fanfare) played directly on the TV on problem, but it refused to play any big files (~87 GB).
Really? That’s bizarre. Was it that they wouldn’t fit on the USB (possibly because of FAT32 formatting instead of NTFS or ExFAT), or the TV didn’t recognize the files? Or did it start to play, then stutter?
My other thought would be that the TV doesn’t support h265, but that seems unlikely to me with a UHD TV.
I’ll let you all know if I end up attempting to author the 2160p files onto 100GB discs, but considering how well the software handled the authoring of 1080p discs, I would assume it would work just fine.
I’d be more concerned about playback compatibility in UHD BD players than ease of authoring.
