How to play MKV on LG TV? Although LG TVs support MKV, some files may not play because of codec or other compatibility issues. This article explains the common causes and shows how to convert MKV to MP4 using MiniTool Video Converter or Convertio, including converting MKV to MP4, choosing the output format, and starting the conversion.

Does LG TV Support MKV

Yes, LG TVs support MKV files. However, some MKV files may not play properly because of unsupported video or audio codecs.

MKV (Matroska) is a multimedia container format that can store video, audio, subtitles, and images in a single file. If an MKV file cannot play on an LG TV, checking the codecs or converting the MKV file to a compatible format can help resolve the problem.

Why Can’t You Play MKV on LG TV

  • Codec incompatibility
  • Higher bitrate or frame rate.
  • File Corruption or damage
  • Firmware incompatibility

Why can some MKV files play on LG TV while others can’t? Below are the reasons why your LG TV can’t play MKV.

1. Codec Incompatibility

MKV is a container format that supports a wide range of audio and video codecs, some of which are not supported by LG TV, such as Dolby True Audio. This results in the LG TV not being able to play the MKV file.

2. Higher Bitrate or Frame Rate

LG TV only supports MKV files in certain bitrates and frame rates, for example, 4K H.264 at 30fps/60fps, 4K/8K HEVC at 60fps, 1080p VP8 WebM at 60fps, etc. If your MKV file has a higher bitrate or frame rate, it may be unplayable on an LG TV.

3. File Corruption or Damage

If the MKV file is corrupted or damaged, it may cause the not playing issue.

4. Firmware Incompatibility

Outdated firmware on your LG TV might not support certain MKV files. It's always recommended to keep your device's software up to date.
