Does LG TV Support MKV

It’s similar to other containers like AVI, MP4, or ASF (Advanced Systems Format), but is an open standard, openly accessible and usable by anyone. Can I play MKV files on LG TV? LG TV does support MKV format but sometimes encounters issues with playing MKV files.

Why Can’t You Play MKV on LG TV

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 LG TV not being able to play the MKV file.

2. Higher bitrate or frame rate. LG TV only supports MKV files in certain bitrate 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 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 Outdated firmware on your LG TV might not support certain MKV files.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.
