A smart LG TV is a big entertainment in our daily life. Nowadays it is convenient to stream and play our local stored movies on HDTVs via a media server or USB flash. MKV file format seems one of LG TV supported native video format for playback. But the weird thing is that your LG TV will reject to play some .mkv videos or movies downloaded from online, or get a copy from DVD/Blu-ray discs. For example, as you're trying to play an 1080p MKV file, it'll say "invalid format", "format not recognized", or there was so much shutter that it was unwatchable. Or even your LG TV won't recognize the audio from MKV files.
Why Some Certain MKV Files Not Playing on LG TV?
Though LG TVs including LG LED, LCD, 3D or Ultra HD 4K TV and more claim to support a wide range of video and audio formats, MKV not playing error also comes up from time to time. Actually, it can be caused by various reasons as below.
1. MKV format/codec is not supported. MKV is just a video container, 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 MKV not playing on LG TV.
2. Media with higher bit or frame rate than specifications. LG TV only supports MKV 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 MKV video is in higher bit rate or frame rate, MKV will goes unplayable, stuttering, dropping frames and so on.
3. MKV file is corrupted. MKV won't play if your MKV file is corrupted or the information in the container is wrong.
4. Incompatible USB and digital camera devices. Many users play MKV videos via USB or digital camera devices. If none of the above is true, it might be an issue of USB or digital camera devices, which are not compatible with your LG TV.

Of course, if you're clear which codec is the culprit, for example, mkv file audio not supported on LG TV, you can transcode the embedded codec without changing video container, for example, go to "Profile" > "Common Video" > MKV (h.264+aac) to transocde MKV HEVC to H.264, and DTS to AAC.
If your source MKV not playing on LG TV owing to higher specifications, you can make them playable with the following advanced settings:
