I've seen an older thread on this topic but it doesn't look like anyone found a solution to disabling the screen saver, so I'll try a new one.
On virtually all my LG TV's (I have three OLED's and two LCD), the screen saver interferes with my music app (like Plex, Spotify or Amazon Music). I mainly use Plex for playback of my music which is stored on a central server (NAS) and from the app loaded on a Fire TV stick or cube. After about 20-30 minutes, the album art and other related music information (lyrics, song title, duration, etc) all goes black. If I run Plex (or Spotify) directly on the LG TV via the LG Content store app, the screen saver with fireworks always comes on in about 2 minutes.
I've tried all the different methods to disable the screen saver function including turning off the Timers, Auto Power Off, HDD Storage, etc. I also tried opening the hidden menus by pressing the mute button 5 times but that menu didn't have anything relevant.
Interesting is that the screen saver doesn't come on when using Spotify on a Fire TV stick or if I playback music through a USB device. But i don't use those methods often, mainly Plex to access my music server where I have about 500 CD's stored in ALAC format.
Has anyone found a way to disable the screen saver function? I know the logic for having it (to prevent OLED burn in) but I'm not leaving the same image on for more than the song duration (about 3-5 minutes). It's annoying to check the screen for the a music title or see who is on only to find a black screen looking back. Thanks for any help.
