LG Smart TV (2018+, webOS, USB) Inferred
The LG Smart TV (2018+, webOS, USB) plays MP4, M4V, MKV, AVI, TS, MOV files that use H264, HEVC, VP9, MPEG4, MPEG2 video and AAC, AC3, EAC3, MP3, PCM audio from a USB drive. Anything outside those formats needs the smallest possible fix first — often just a container repackage or an audio swap, with the video left untouched.

Common reasons a file won't play on the LG Smart TV (2018+, webOS, USB)
- AV1 video
- DTS, Dolby TrueHD, FLAC audio soundtracks — the audio is converted, the video is kept as-is
- Files larger than 4 GB on a FAT32 drive — a limit of FAT32, not the player (format the drive as EXFAT or NTFS to avoid it)
Good to know
- DTS decode was dropped on 2017–2022 models and partially restored on some 2023+ models — treat as unsupported
- Dolby Vision from USB works only on DV-capable panels; profile 5 files may show green/purple tint
- webOS is picky about AVI: modern encodes in AVI containers often fail
