LG TV: what plays from USB

Type your model (OLED55CX, OLED65C2, 55UN7300, 43UK6200) to load its profile, then drop a file.

Your files stay on your device. Nothing is uploaded.

1 Your TV, box or projector

Not on the list? Paste the “supported formats” table from the manual

2 Your videos

Drop videos or a whole folder here Series, films, home videos — any number, any size. .srt files with the same name are picked up as subtitles.

3 USB stick, sound and subtitles

Fit everything on a stick of Stick format Split files over 4 GB into parts instead of shrinking them Picture quality Tidy up: “Show/Season 01/Show S01E02”, safe file names

Questions

Why does my LG show “unsupported audio”?

The track is DTS (or TrueHD). Convert just the sound — the video is copied.
