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.

    For me, toggling the setting does not work. I uncheck the 'Use Dolby Vision' box then Windows+alt+B twice to toggle out of Dolby Vision HDR mode it is stuck in, to SDR mode then back to HDR mode which resets it back to HRD10.

    Installed 24H2 for x64-based Systems (KB5060829) today. Didn't fix anything for me.

    Same here. Absolutely no change. They way I've set up my LG C4 works normally after it is fully booted. But of course, with DV disabled in the LG menu, DV is not available in games. I actually have gotten DV to work properly in Mass Effect Andromeda. But other HDR titles will stay in DV vision once it has been triggered. Meaning once you've used DV, the screen on my C4 will not toggle back to HDR10 once you're back on the desktop. It will stay in DV mode even when you start a game using standard HDR.

    Hi, with my issue, the problem would reoccur every time I switched to my external display, which is an LG C2 TV. So, I needed to toggle Dolby Vision every time I swapped to this display to play a game. So far, the CRU fix has proven permanent.

    I also installed KB5060829 today, and this has had no effect on the issue.
