Windows 11 keeps forcing Dolby Vision every time I start up, even though I turned it OFF

Hi all,

I have an LG OLED G4 connected to my PC (Windows 11, NVIDIA 4090 graphics card). In Windows settings I’ve turned off “Use Dolby Vision mode,” and on the TV I’ve also disabled the Dolby Vision option for that HDMI port. Despite that, every single time I power the TV and PC back on, Windows starts in Dolby Vision anyway.

The picture looks brown, dim, and washed-out until I manually go into Windows, turn the Dolby Vision toggle on and then off again. After that, it switches to the normal HDR mode I actually want (“HDR Game Optimizer” on the TV) and everything looks fine—until the next restart, when the whole problem repeats. If I turn the TV off and on again while the PC is still on, it says in HDR Game Optimizer; it's when I restart the PC and the TV that it reverts to Dolby Vision again. It'll even revert to Dolby Vision if I just restart the PC, leaving the TV on the entire time. I've also tried hard power-cycling the TV (unplugged for one minute) after getting all the settings the way I want) and the problem still occurs.

In short:

  • Dolby Vision is OFF in Windows.
  • Dolby Vision is OFF in the TV’s input settings.
  • Yet Windows still chooses Dolby Vision at every cold boot or wake-up.
  • Manually flicking the toggle fixes it temporarily, but the setting never sticks.

This started after a recent Windows and graphics-driver update. It’s making HDR on my PC basically unusable.

Please let me know how to stop Windows from forcing Dolby Vision at startup, or escalate this as a bug. I just want my system to stay in regular HDR when I’ve told it to.

    I am having the same issue, does anyone have the correct name for the Dolby Vision DWORD registry key?

    I think the missing registry key is whats causing the need to toggle DV on and off because its not writing the setting to the registry so it doesn't persist so you have to toggle it on and off to flip the bit in memory until it clears on a restart.

    Only DWORD I have under Computer\HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\VideoSettings is DisableHDROnBattery

    Under the HDR option I don't even see the Dolby Vision toggle anymore.

    "VideoSettings" doesn't exist, does ANYONE have the CORRECT registry keys for this? I'm about to tear someone's damn head off over this.

    Same issue here..This has been driving absolute nuts for the past few weeks. Been trying to resolve it manually for so long, but got fed up and started looking for fixes on google, so many threads and posts I've found about this issue....AND ITS STILL NOT FIXED!!!

    There is no option to disable/enable DV on an LG C2 OLED, there simply isn't any DV option in ANY menu. So for now every time I turn on the PC, I have to tick the "use dolby vision mode" (as it's unticked and disabled by default, but still turns itself on startup) and the disable it again to force it off.

    Very frustrating this, come on get this resolved as this was never an issue up until a few weeks ago.
