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.

    right so my pc has just this second installed a new latest update KB5056579

    MS states this was an April 2025 update so no idea why I'm receiving this now.

    after a few restarts and double checking I can confirm that Dolby vision seems to be staying unticked currently. this is using an LG C2.

    what happens is the pc boots up, display flicks from HDR to Dolby vision while in the windows bootup stages, then flicks back to HDR by the time I load onto the desktop.

    I check the settings and DV is still unticked. I'm not advising anyone to follow this update but at the Mo it seems to be keeping Dolby vision off for me. its very annoying problem so I'm not installing any more windows updates until I know MS acknowledges this and fixes it.

    Yep, it was this one that I installed and it fixed the issue for me

    KB5060829

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

    That's the problem, so we cannot inactivated or activated again.

    I'm using Dolby Vision well, color problem is seems display issues.

    Why removed the toggle option from the recent builds? It's a stupid solution.

    even i can't activate with ViveTool, but Dolby Vision is still activated.

    Same issue, started yesterday. Incredibly annoying that despite Dolby Vision being disabled in HDR mode, Windows always starts in DV and I have to enable and then disable again for it to actually work. I would disable it on my LG OLED side but naturally there is no option for that. On top of that Windows can't seem to handle brightness. It keeps blinking which is just crazy.

    The only reason why I kept using Windows is because I had hardware problems when playing with with Endevour OS (Arch distro) and I don't need my main PC to be a project (I have enough of that at work). Now I'm seriously considering some "just works" Linux disto...

    No, it doesn't because the whole reason this is a problem is THAT OPTION DOESN'T EXIST/WORK ON MANY PCs CONNECTED TO AN LG TV! Can people stop replying with useless advice without understanding the situation, thanks.

    Just toggle Deep Colour, off and back on in the display's own settings.

    I have an LG G4 and I still have that option. It does work when I set it initially, however, the setting does not stick after a reboot. Once I enter display settings, HDR switches on automatically (Dolby Vision switches off).

    This behavior was reported previously, so all in all you are correct, the bug is not solved.
