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 unsure if the mentioned tool "CRU" it works in this setup."

    You should try it; I'm sure it will work for you as well. You can even revert it. Here's somebody explaining how to do it: https://powrusr.com/fix-the-dolby-vision-black-screen-issue-in-games-like-need-for-speed-heat/In a different context, but this is precisely what I did for my second monitor. "The registry entry mentioned in the first reply does not exist"

    HKEY_LOCAL_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\VideoSettings

    should exist if

    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\VideoSettings

    doesn't

    But the reply which suggests removing or changing something in it is useless anyway. The person who did it didn't even know the exact option names.

    HKEY_LOCAL_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\VideoSettings should exist if HKEY_LOCAL_MACHINE ... doesn't. However, I had no DV related DWORDs in there and adding DolbyVisionEnabled or DolbyVision with 0x0 value didn't do anything for me.

    I have now removed the EDID DV flag with a tool called CRU:

    No more DV since then.
