To play video files on the TV, the file extension, codec, and other requirements must be met.
If only a specific video file cannot be played, it is not a problem with the TV, but a codec used in the
video file is not supported by the TV.
So it's not a product defect and you need to check the file and TV for compatibility.
You can check the codec information of video files by installing a third-party video encoding program on
your PC.
Causes and Symptoms
- The video files are encoded with an unsupported codec.
A wide variety of codec types exist, including MPEG and WMV series.
Try this
Play a video file on your PC.
➔ After installing a third-party encoding program on the PC, play the video file with it to check the playback information.
➔ Compare the playback information of the file with the TV requirements for supported video files.
If the video file codec specifications do not match the required video file format for the TV, you cannot play the file on your TV.
- For detailed specifications, refer to the user guide.
- For LG TVs released in 2020, the DTS codec is not supported.
