Windows 10 – How to disable automatic brightness adjustments

For computers with a light sensor, typically laptop computers, Windows 10 has the ability to automatically adjust the screen brightness depending on the ambient light levels.

This feature can be more annoying than helpful, either leaving your screen too dark or frequently adjusting the brightness levels.

Here’s three ways to disable the automatic screen brightness feature.

Method 1: using the systems setting

  1. Open the Windows start menu and click on ‘Settings’ (a cog icon)
  2. In the settings window, click on ‘System’
  3. Windows10-DisableAutoBrightness5
  4. The ‘Display’ menu should be selected on the left, if it is not – click on ‘Display’
  5. Un-tick ‘Change brightness automatically when lighting changes’

Help – I don’t have the ‘Change brightness automatically when lighting changes‘ option

If you don’t have the ‘Change brightness automatically when lighting changes’ option it’s likely your computer does not have a light sensor and therefore does not have the automatic brightness feature.

If you’re sure your computer does have a light sensor – try checking the manufactures website for the correct driver and/or software package. It is possible that Windows 10 support is not provided.

In this case you will need to use the manual brightness adjustments. On laptops, these are usually done using buttons on or new the keyboard – sometimes in combination with a Fn (function) key. For desktop computers, the monitor will have buttons and a menu on the front or the side of the monitor.

Help – ‘Change brightness automatically when lighting changes’ won’t change

If your laptop is connected to two screens – in extended mode – the ‘Change brightness automatically when lighting changes’ option won’t change.

This appears to be a bug with Windows 10.

Method two: change the power plan advanced options

  1. Open the Windows start menu and click on ‘Settings’
  2. In the settings window, click on ‘System’
  3. Windows10-DisableAutoBrightness5
  4. Click on ‘Power & sleep’ in the left hand menu, then click on the ‘Additional power settings’ link
  5. Windows10-DisableAutoBrightness6
  6. For the power plan you currently have enabled (balanced by default – the enabled plan will be bold), click on ‘Change plan settings’.
  7. Windows10-DisableAutoBrightness7
  8. Click on ‘Change advanced power settings’
  9. Windows10-DisableAutoBrightness8
  10. Expand ‘Display’ -> ‘Enable adaptive brightness’ and make sure the setting is set to ‘Off’
  11. Windows10-DisableAutoBrightness3
  12. Click ‘OK’ to save the changes.

Help – The ‘Adjust my screen brightness automatically’ option is greyed out

This issue sounds like a driver support issue – for example the wrong software for the video card is installed.

In this case, you can try

  1. installing the latest driver / software updates from the laptop manufactures website
  2. opening the computer Device Manager and changing the driver for the video card to the Microsoft basic driver.

  2. Hi,
    I my laptop is running windows 10, and the screen automatically dims out when i open any dark themed website and again brightens up slowly when i open any normal website with white background.
    I checked the options you mentioned but my system is having none of them, please guide me if this is inbuilt display issue or any turn around ?

  3. I’ve tried both methods; for both I can’t see the option, although my brightness changes as I cycle between light and dark mode apps. Is there a different toggle I should search for?

    1. I found a solution to this issue on Surface Book 3.

      1. Open Intel Graphics Command Center. (If you don’t have it installed then get it from the Microsoft store).
      2. Go to the “System” tab on the left hand panel
      3. Click on the “Power” tab along the top
      4. Make sure all settings are switched to off for On Battery. The main ones are “Panel Self Refresh” & “Display Power Savings” – switch these to off.

  4. My brightness is adjusting to the brightness of the background. I’m not sure this makes sense, but if I’m using a dark mode application, the computer turns the brightness down automatically, and if I’m looking at a mostly white screen it automatically turns the brightness up. I looked through all of the brightness and power settings, but there doesn’t seem to be a setting for it. It’s incredibly annoying, can someone help?

  5. there is no display there and also in display settings there is no auto brightness either and also i couldnt find a setting about brightness in intel or nvidia drivers please help me

  6. Thank you so much, my computer has been doing this since I got it and it annoys me every time I see the brightness go down. The instructions were very clear and the problem was resolved quickly, thanks again!
