To try this solution, you must first uninstall both your Plex media player and your Plex server. This will cause data and library loss in the app. So before starting, search on Google to find a good procedure for backing up your data. Then uninstall and reinstall your Plex media player and PMS. Make sure to clear any cache files so that the cache does not interfere with your app when you reinstall it. Check the Native OpenGL box and try running your media file in the proper format.

If the video formats are not supported by the streaming devices, the Plex app, or both of them, then you may encounter the Plex black screen issue. Moreover, even if your streaming devices and Plex both support the video format you’re playing, you need also pay attention to the video codec, which can also cause the Plex no video only audio issue.
