Latest Update Turns My Screen Green [Dolby Vision]

The best workaround I found to fix it is this:

Windows side: make sure Dolby Vision is disabled under the HDR settings in display settings. There is an arrow next the HDR toggle to expand it.

TV side: All setting -> General -> External Devices -> HDMI Settings -> 4:4:4 Passthrough. Enable this.

It fixed my problem and HDR and G-sync work great, no more green screens or weird brightness glitches.

Hope that helps

Thank you!! I spent over an hour troubleshooting this problem, and it turns out the solution was so simple! Just disable Dolby Vision mode under the HDR settings in Windows.

I figured the TV's HDMI port might be damaged, the Nvidia drivers were broken, etc.. but it turns out it was a Windows bug...

Older LG OLED models does not seem to have this option "Dolby Vision PC".

My B39LA (SW Ver 23.22.02) does not have this option. I can only turn HDR off/on without direct control what to use (HDR10 or Dolby).

This need a fix ASAP from MS. Simply dont enable DV automatically, let the user decide. I have to pause automatic updates to avoid the green screen.

Same issue for me too, was working fine but started doing this earlier this month, 7800x3d, 3080ti, LG C2, latest win11 update, DDU and latest Nvidia game ready drivers. I have tried different old HDMI cables and bought another new HDMI2.1 one.

After trying to calibrate the monitor I noticed that it isn't actually a green tint, but a total lack of the blue channel, that makes everything look green or magenta.

Edit the C2 doesn't have the "PC Dolby vision" option in the menu as the G5 above has, or if it does it isn't in the same place and I couldn't find it.

Well I got my 55" G5 today, at first i thought it was suffering the same issue, however I discovered that i had to put the PC into " use Dolby vision mode" first and it would look like the pink/green puke but with an extra bit of F-you by the bottom third of the screen looking like the screen was physically damaged, but before I turned it off I went into the the LG settings and under "General>>External Devices>>HDMI settings there is a "Dolby Vision PC" switch, when I turned that on it worked as intended, I never checked the G2 for this setting in this location and Don't feel like hooking it back up.

And oh my word is jumping from a G2 to a G5 an epic upgrade!!!!

Dolby Vision and Dolby Vision PC must be functionally different and I now think we should treat them as such as it seems as though that is what is happening, I also now believe that older TV's even if they support dolby vision may never get this functionality, if it is just software/firmware then hopefully manufacturers like LG who say they will give 5 years of feature upgrades will roll this back to older TV's

But if it is TV hardware dependant I don't think there is much hope.

However Microsoft still needs to fix this random activation bug

Yeah this is happening to me on the latest update too. Even though I have disabled Dolby Vision in settings, it is only a temporary fix as on the next restart everything is green/purple again and I have to go back into settings and turn Dolby Vision back on and then off again to fix it every time. Really annoying and needs to be addressed in a patch ASAP.
