Several reasons may explain why your OPTOMA PK320 projector does not play an 8 MB video stored on its internal memory:
1. Incompatible video format
The projector supports certain specific video formats such as MP4, AVI, or MOV. If your file is in another format, it will not be played. Check the video file format and, if necessary, convert it to a compatible format.
2. Unsupported resolution or codec
The projector may have limitations regarding the maximum resolution or supported video codecs. A resolution that is too high or an unsupported codec may prevent playback. Try reducing the resolution or using a common codec.
3. Corrupted video file
If the file is damaged or incomplete, the projector will not be able to read it. Test the video on another device to check its integrity.
4. Memory space issue
Ensure that the internal memory of the projector is not full, which could prevent proper playback functionality.
5. Firmware update
An outdated firmware may lead to incompatibilities. Check if an update is available for your projector and install it.
In summary, check the format, resolution, file integrity, memory space, and firmware to resolve this video playback issue on your OPTOMA PK320.
