Enable Adaptive Screen Brightness in Windows 10

Sometimes I like to work on my notebook while sitting in the dark and drinking a strong cup of coffee. I have to manually adjust the screen brightness to suit the ambient light in the room. If it is a little darker in the room, then the screen brightness has to be turned down a little to avoid stress on the eyes and if the room is well lit, then I can work even with the brightness turned up to the maximum. But if you have an ambient light sensor in your notebook computer, then you can make use of the adaptive brightness controls in Windows 10 to make it automatically adjust the screen brightness to match the ambient light brightness level. This is not only comfortable for the eyes, but also saves the notebook battery.

By default the adaptive screen brightness is turned off. Here is how you can enable the adaptive screen brightness in Windows 10:

  1. Press the hotkey Win+R in your keyboard. This will open the Run dialog.
  2. In the Run dialog, type control powercfg.cpl,,1 and press Enter. This will open the Advanced Power Options window.Windows 10 Adapative Screen Brightness
  3. In the Advanced Power Options window, scroll down the list of options. Expand the option Display and then Enable Adaptive Brightness. Next to the Setting, select On from the drop-down list.Windows 10 Adapative Screen Brightness
  4. Click on the OK button to save the settings.

After you have enabled the adaptive brightness control in Windows, you can try switching off the room light or pulling the curtains in the Windows and see how your computer’s screen brightness level changes. It need not be mentioned that this adaptive brightness control works only if your computer has ambient light sensor in it.

Conclusion: It is very easy to turn on the adaptive screen brightness in Windows 10 to let it automatically adjust the screen brightness as the ambient light brightness level increases or decreases. It is useful for reducing stress on the eyes and making your computer’s battery last longer.

    I think you will find it should be the other way round. Try to do better in future…
