Dolby vision screen brightness changes before scene changes

Plex Players

it seems that the screen brightness on my googletv changes a half second before the video scene changes. any idea on how to fix this?

This has nothing to do with Plex.
If I had to venture a guess, I’d say you have enabled “Adaptive brightness” (or whatever they call it in their menus) in the settings of the TV.

UPDATE ABOUT FOR ALL OF US WHO HAVE DOLBY VISION BRIGHTNESS PROBLEM, THERE IS A WORKAROUND SOLUTION AND SOMETHING LIKE A GOOD NEWS.

I found these instruction on xda forum with beyond TVs:

  1. Activate Quick Start (EVEN if you have this option ON, just do TURN OFF AND TURN ON THIS OPTION once AGAIN)
  2. Turn off (hold power button on remote control 5 seconds and say YES/ OK to turn off question and unplug the TV and of course after 10-15 sec, plug in powercord to TV again)
  3. Turn on the TV
  4. Let it load all the GTV UI
  5. Turn off the TV with the remote control button (but not completly, just one short click - to quick start standby mode)
  6. Turn the TV back ON with the button on the remote
  7. Put the movie or series with Dolby Vision
  8. Enjoy, finally, the movie or series without brightness changes in the scenes
