Why is My Video Not Playing on LG TV?

“I downloaded a movie in MKV format. It plays on my computer with VLC but won’t play on my LG C1 TV. I know the TV supports MKV because it plays other MKV. Is there a file converter software I can use to convert them to something the LG will play?”

There may be occasions your MP4, MKV, or other video files won’t play on LG TV even though you’ve successfully played similar files before. The truth is, MP4 and MKV are containers that can hold different video and audio codecs. Remember that it is not only the container but also the codecs are needed to be supported by your LG TV for normal playback. In other words, a video with a supported format still won’t play if it is encoded with an unsupported codec.
