Windows 10: How do I turn off adaptive brightness? I've tried everything

I have a Dell G5 15 5500, with a dedicated NVIDIA graphics card. Windows 10.0.19042 Build 19042. When my laptop isn't plugged in, every time the image on my display changes, the brightness very noticeably fluctuates, but I can't turn this off. I've tried:



Attempt 1: Display Settings

There is no option to turn this setting off. Image



Attempt 2: Power Options

Again, there's no "Enable Adaptive Brightness" option. Image



Attempt 3: Intel Graphics Command Center

Once again, there's no option. Image



Attempt 4: Regedit

Apparently I should be able to navigate to this registry:

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Intel\Display\igfxcui\profiles\Media\Brighten Movie

but it doesn't appear for me. Image



Attempt 5: Command Prompt

I ran the command prompt as administrator as specified here, but nothing changed even after a restart.





I updated all my drivers and have no idea why nothing is working. Any help is appreciated.

How to turn off adaptive brightness?

Hi, I have a Windows 10 laptop Intel(R) Core(TM) i3-8130U CPU @ 2.20Ghz that I just got a week ago.

The brightness keeps dimming with darker images being displayed and brightening with lighter images. I've googled solutions to this problem and none of them have worked.

• I've updated the graphics driver
• rolled back said driver
• tried looking in the BIOS (which there are no brightness settings anyway)
• restarted the laptop
• shut down and turned on the laptop
• gone into power settings and turned off adaptive brightness On Battery and Plugged In
• tried downloading a new graphics driver
• looked into windows settings with no checkmark to disable adaptive brightness
• turned on high video performance
• tried to find Adaptive Brightness in services and disable it (it didn't seem to exist)

almost everything I've seen but none have helped. the laptop is for work and entertainment and I'd like to use it at full brightness most of the time, please help.

Thank you in advance.

 

How do I turn off adaptive brightness?

Surface Pro 6, manually updated to 2004 last week. There is now no way to turn off adaptive brightness. Seeing the screen constantly stepping brightness up or down is one of the most irritating things in the universe, and I can’t turn it off.

I've tried all the so-called solutions that I could find; none work. I had previously turned it off with the Intel Graphics Control Panel but that has been replaced with Intel Graphics Control Center, which does not provide that option. This problem appears to be related to the latest Intel display driver, which is necessary for the 2004 version. I can't roll back to a previous version because of this 2004 support. Trying to install an earlier Intel driver fails. I can uninstall the Intel display driver and the Windows default takes over with perfectly good display results, but the camera no longer works (???) and other things aren't just right. No registry changes that I've found, no group policy support, no nothing, even from here: Enable or Disable Adaptive Brightness in Windows 10

So I am considering going back to the previous version but before I do this I would like some advice:

1. Anything to try that might have been missed?
2. Does going back to a previous version actually work these days (2004 to 1909 or whatever the previous version is)? All the stuff to roll back is still installed.
3. Will the roll-back get the SP6 back to the exact configuration, including drivers, that it was in before the update? I haven't changed or added any apps since the upgrade, so that won't be a problem.
