How to Disable Dynamic or Adaptive Brightness in Windows 10

After the latest update of Windows 10, I started to notice that my laptop’s screen was automatically changing the screen brightness depending on the application I am using or how bright my room is. This is because of a feature in Windows operating system that dynamically changes the screen brightness of your computer depending on the ambient light. This works only on the computers that have ambient light sensors that detect the level of brightness in your room. So if you are sitting in a dark room, Windows 10 will lower the screen brightness to reduce strain on your eyes. Similarly, in bright daylight, Windows 10 will increase the screen brightness to maximum level.

But this can become very annoying if you are not sitting in a place that has a uniform brightness. If this feature is giving you a headache, then you can turn it off. Here is how:

  1. Press Win+R to open the Run dialog, type powercfg.cpl and press Enter.
  2. Click on Change plan settings next to the selected power plan (power plan that is active on your PC).Disable Adaptive Brightness in Windows 10
  3. Click on Change advanced power settings on the next screen.Disable Adaptive Brightness in Windows 10
  4. In the power options window, expand Display and then Adaptive Brightness. Set Off for both On battery and Plugged in.Disable Adaptive Brightness in Windows 10
  5. Click on the OK button. Close all the windows opened in the steps above.

After this, you will not experience the annoying behavior of Windows 10 that changes the brightness of your screen dynamically. If you do not see this setting in the step 4, then perhaps your computer screen does not have those light sensors that can calculate the lumen value of the ambient light of your surroundings. Usually the desktop computers do not have these sensors but almost all of the modern notebooks are coming with these light sensors that can enable this setting in Windows 10.
