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.

    An additional problem on my LG C3 is that after the Dolby Vision Windows 11 update, I can no longer get 4k @ 120Hz with HDR, and I can't get VRR to work. I'm limited to 4k @ 30Hz to get HDR (without VRR), and am forced to turn off HDMI Deep Color to get anything to display at all. With HDMI Deep Color on, my TV displays a black screen as soon as Windows boots.

    Setting 4k refresh rate to 60 drops HDR, and trying to go to 120Hz drops the resolution to 1920x1080. This wasn't a problem before the Dolby Vision update, and it's super lame since it's a living room gaming PC.

    Hopefully Microsoft can sort this out with LG. It's taken my living room gaming PC out of commission until this is fixed. (My C3 is on the latest current firmware 23.20.69.)

    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.

    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...

    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.

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

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