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.
Why Won’t Videos Play from a USB Drive on Your LG Projector?
- 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.
Troubleshooting Steps
Step 1. Test the Video File on a Computer
- 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.
Step 2. Check the Supported Video Formats
The following table provides examples of video formats and codecs supported by some LG projector models.

Frequently Asked Questions
- Q. Why Won’t an MP4 File Play on Your LG Projector?
- A. MP4 is a container format, meaning the video and audio codecs inside the file can vary. Even if your projector supports the MP4 extension, the video may not play if its video codec, audio codec, or resolution is not supported.
- Q. Why Does the Projector Show an "Unsupported File" Error Even Though the Video Plays on a Computer?
- A. Computer media players typically support a wider range of codecs than projectors. Even if a video plays normally on a computer, it may not play on your projector if its video codec, audio codec, or resolution is not supported.
