A smart LG TV is a big entertainment in our daily life. Most of you would like to transfer some downloaded video files onto it for enjoyment on the big screen. Although LG Smart TV claims to support MP4 files, sometimes we still encounter LG TV won't play MP4 issues: "My LG TV refuses to play some MP4 files, displaying an unhelpful codec error message. I'm seeking for a way to get MP4 playable on LG TV." So what's the matter? Don't worry. Just read on to figure out why LG TV not playing some certain MP4 files and how to watch these MP4 videos on LG TV easily.
Why Some Certain MP4 Files Not Playing on LG TV?
Broadly speaking, MP4 format/codec incompatibity lies in the major cause of LG Smart TV not playing MP4 videos. LG TVs support MP4 files, but they only support playing MP4 videos in H.264/MPEG-4/HEVC video codec and AAC and MP3 audio codec. However, MP4 is a container format, which can be encoded with a wide range of codecs, like HEVC, H.264, MPEG-4, VP9, DTS audio etc. While LG TV has poor compatibility with some of the codecs, such as Dolby True Audio and DTS Audio, which will make MP4 not playing on LG TV.
The second possible reason may be caused by the higher bit or frame rate in your MP4 file. LG TV only supports MP4 files in specific bitrate and frame rate, for example, 4K H.264 at 30fps/60fps, 4K/8K HEVC at 60fps, 1080p VP8 WebM at 60fps etc. If your MO4 video is in higher bit rate or frame rate, MP4 will goes unplayable, stuttering, dropping frames and so on.
Incompatible USB or corrupted MP4 file may also cause the playback error. Many users play MP4 videos via USB. If none of the above is true, it might be an issue of USB devices, which are not compatible with your LG TV. Moreover, MP4 won't play if your MP4 file is corrupted or the information in the container is wrong. Whatever, the last two possible reasons can be easily checked out.
