I have this common issue where W11 automatically adjust the screen brightness and contrast based on content that’s displayed.I've searched the microsoft docs and forums to resolve this, but nothing works. https://support.microsoft.com/en-us/windows/content-adaptive-brightness-control-in-windows-292d1f7f-9e02-4b37-a9c8-dab3e1727e78 The "Help improve battery by optimizing the content shown and brightness" drop-down is nowhere to be found :https://imgur.com/Ga0AexXI turned off every battery saver options, my current battery
