Fix: Windows 10 Adaptive Brightness won’t Turn Off

Some Windows 10 users are reporting that there’s no longer an apparent way to turn off adaptive brightness.  Even with the Adaptive Brightness settings intentionally set to off, a lot of affected users are reporting that their screen is still getting brighter or darker constantly.

Adaptive Brightness won’t turn off

What is causing the adaptive brightness feature to remain ON?

We’ve investigated this particular issue by looking at various user reports and the repair strategies that are commonly being used to fix this particular issue and finally stop the screen brightness from changing dynamically.

As it turns out, there are several different potential culprits that might end up triggering this particular issue:

  • Adaptive Brightness is enabled for the current power plan – Even if you previously disabled adaptive brightness, you might currently be on a different power plan in which the setting is still enabled. In this case, you will be able to resolve the issue by disabling adaptive brightness for all available power plans.
  • Intel’s Display Power Saving Technology is enabled – As it turns out, Intel has a proprietary technology that is perfectly capable of overriding your operating system settings regarding adaptive brightness. Several affected users have reported that the issue was only resolved after they disabled Display Power Saving Technology from Intel Graphics and Media.
  • Contrast Enhancement and Film Mode is enabled – There are two Intel Graphics Control panel settings that are known to cause this particular issue – Contrast Enhancement and Film Mode Selection. Some users have managed to resolve the issue after disabling the two options from Intel HD Graphics Control panel menu.
  • Vari-bright is enabled – If you’re using an AMD Radeon GPU, chances are the issue is being caused by a proprietary AMD technology called Vari-Bright. If this scenario is applicable, you can resolve the issue by disabling the feature from AMD Radeon Settings.
  • Adaptive Brightness is enforced by Registry key – It’s also possible that adaptive brightness insists on remaining active even after you disable the option from Power options because a registry key is keeping it active. In this case, you can disable adaptive brightness indefinitely by disabling the option via Registry Editor.
  • Sensor Monitoring Service is active – There’s one particular service (Sensor Monitoring) that is known to enforce adaptive brightness even if the option was previously disabled. If this scenario is applicable, you can resolve the issue by disabling the sensor monitoring service via the Services screen.
  • Integrated GPU is glitched – In some cases, the error is reported to occur on dual GPU machine. If the integrated GPU gets stuck in a limbo state, adaptative brightness will kick off. If this scenario is applicable, you can resolve the issue by disabling and re-enabling the integrated GPU.

If you’re struggling to resolve this particular issue, this article will provide you with several different troubleshooting steps. Down below, you’ll discover several different methods that other affected users have successfully used in order to fix this particular problem.

Since the potential fixes are ordered by efficiency and difficulty, we advise you to follow them in the order that they are presented to improve your chances of success. Let’s begin!

Method 1: Ensuring that the Adaptive Brightness feature is turned Off

First things first, it’s important to start this troubleshooting quest by making sure that adaptive brightness is actually turned off from inside the Power options menu. Even if you previously turned it off, you might have since switched to a different power plan that enabled the feature once again.

Here’s a quick guide on ensuring that adaptive brightness is turned off from the Power Options menu:

  1. Press Windows key + R to open up a Run dialog box. Then, type “ms-settings:powersleep” and press Enter to open up the Power & Sleep tab of the Settings app.
