What to Check First
- The video may not play if the file is corrupted, or if its file extension, video codec, or audio codec is not supported by the projector.
- A codec is a method used to compress and decompress video or audio data for storage and playback.
- Files with the same extension, such as MP4 or AVI, can use different codecs. A video may not play even if its file extension appears in the supported file list.
- 1. Play the video file from the USB drive on a computer.
- 2. If the file does not play on the computer, it may be corrupted.
- 3. If the file plays normally, check its file extension, video codec, audio codec, and resolution.
- 4. Check your projector’s user manual to confirm that your model supports these file specifications.
- If you see an "Unsupported File" error when playing a video from a USB drive on your LG Projector, the file format, video codec, or audio codec may not be supported. Check the file's properties on a computer to ensure they match your projector's supported specifications.
