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 with my LG C4 TV and Windows 11. Dolby Vision switches on upon reboot even if I turned it off just before. But it does not even require a reboot. It even turns on again if I had my PC running for a while and restart my TV. Interestingly, I don't have to turn Dolby Vision off via the settings to diable it again. It is enough to right-klick on desktop and then klick on display settings without actually toggling off Dobly Vision in the settings. Apparently, Win11 recognizes itself that something is wrong as soon as I open the settings window.

    Setting the color to limited, instead of full, in nvidia control panel fixed it for me. Turned hdr back on in display settings and colors are normal now with hdr working.

    Just started happening to me as well. Dolby Vision just started forcing on, and it is broken as well, making everything green, grey, and purple.

    This happens whenever HDR is on and I open any window. HDR Games will still boot with normal working HDR. But opening anything else like a browser, settings, files, etc. will force on broken Dolby Vision. It will sometimes flicker between Dolby Vision and normal HDR as well.

Toggling Dolby Vision on and off again will fix it, but a PC restart or sleep mode breaks it again.

    I am using an LG C2 TV, with an AMD GPU with the latest drivers. Though this started happening to me only a few days ago, so I assume the problem is a Windows update.

    EDIT: I followed the suggestion to uninstall the update that causes the problem, KB5058499, and it solved the issue. And I turned off the option to get the latest updates as soon as they are available in hopes it won't automatically install itself again.

    I have the same issue, after restarting my PC earlier I get the pinkish purple/green screen. I noticed when the video range is set to full it forces dolby vision which seems to be the issue. I switched to Limited and this got rid of the issue but with limited it crushes blacks. Ive always used Full and never had any issues. I always have dolby vision turned off as quite frankly, I think it's rubbish and it shows it just causes issues.

    If this is due to a MS update then when will this be fixed?
