Why Are Some MP4 Files Not Playing on LG TV?

Although MP4 is one of the video formats supported by LG TV, if the codec within MP4 is not supported, it will not play on LG TV.

It is important to note that MP4 videos can be encoded by different codecs, such as MPEG-4, H.264, HEVC, etc. However, LG TVs do not support all of these codecs, such as HEVC (unless the content is officially provided by LG). Meanwhile, LG TVs also have poor support for Dolby Digital and DTS audio. Therefore, you may find that some MP4s play without image or sound.

The good news is that the solution to this problem is simple - you just need to convert the unplayable MP4 to a format supported by your LG TV. Please read on.
