How Do I Turn Off Auto-Brightness Windows 10?


The Auto Brightness feature of Windows 10 is a great way to conserve battery power as it automatically adjusts the screen brightness based on the environment.

This feature is very useful for those who spend a lot of time in low-light environments such as reading in bed or working in dimly lit rooms.

However, some people prefer to manually adjust their screen brightness.

The Auto Brightness feature can be turned off or on with these steps:

  1. Press the Windows key and type “Control Panel” then press Enter.

  2. Click on Display and then click on Adjust the appearance and behavior of your display.

  3. Click “Change brightness automatically when lighting changes” if you want to turn off this feature, or click “Change brightness automatically when lighting changes in the following situations” if you want to enjoy this feature.

  4. Click Apply.”


Another Method


To enable or disable this feature on Windows 10:

  • Open the Settings app
  • Select “System
  • Select “Display
  • Turn the “Change brightness automatically when lighting changes” option on or off.

You’ll only see this option if your device has an ambient brightness sensor.

You can change this setting through the Control Panel, too:

  • Open the Control Panel
  • Select “Hardware and sound
  • Select “Power Options
  • Click “Change plan settings” next to the power plan you’re using
  • Click “Change advanced power settings.”

Expand the “Display” section here, and then expand the “Enable adaptive brightness” section. The options here let you control whether adaptive brightness is used when you’re on battery or when you’re plugged in. For example, you could disable it when you’re plugged in and leave it enabled when you’re on battery power.

You can adjust your screen brightness both automatically and manually, and both have their time and place. Enabling automatic brightness won’t prevent you from tweaking your brightness with hotkeys or the options in Windows whenever you feel like it, either, so you have nothing to lose by trying all the above options out.

For some Windows PCs, there’s an adaptive brightness or auto-brightness setting that can sometimes present problems for the average user. This auto-brightness feature is powered by ambient light sensors that measure the light surrounding the device and adjust accordingly.

Unfortunately, screen brightness is a highly personal setting and many would prefer to manually adjust these settings. In some contexts, constantly auto-adjusting brightness may be a nuisance.

  • Save the settings through clicking Apply and then OK
  • If you don’t find an Adaptive Display-setting, your device might not have a built-in ambient light sensor.

Adaptive Brightness: How it Works


If you have a smartphone, you’re probably already familiar with auto-brightness windows 10. Your screen changes from very bright to dark based on the light coming in through its sensors. This helps to prevent your phone from being overly bright and unnecessarily wasting battery life.

This same technology is available in certain computers. Microsoft first introduced auto-brightness in Windows 8 computers but Windows 10 PCs may also include this feature.

Luckily, Windows 10 offers several options for changing this setting. Read our article and learn how to turn down the auto-brightness of windows 10 or how to increase the brightness for your display in Windows 10:

On some keyboards, there are keys specially designed to help you modify the screen brightness with ease. On an HP Spectre 13t laptop, you can use the F2 and F3 keys to lower or increase the screen brightness.

On our Lenovo Legion Y520 laptop with Windows 10, you can press the key combination Fn + F11 to lower the brightness and Fn + F12 to increase it.

These keys and keyboard shortcuts are available on most Windows 10 laptops and tablets. Look for similar keys with the brightness-specific sun icon on them.


Where is The Brightness Control on Windows 10?

Some PCs can let Windows automatically adjust screen brightness based on the current lighting conditions. To find out if your PC supports this:

  • Go to Settings
  • System
  • Under Brightness and color, look for the Change brightness automatically when lighting changes check box.

Should I Use Adaptive Brightness?


In this section, you’ll learn whether or not to use adaptive brightness on your device. There are plenty of reasons why it might be in your best interest to adjust or turn off the auto-brightness setting. For example, if your computer’s auto-brightness windows 10 adjustments are distracting from your work or entertainment needs, it could be time to take a look at your settings.

Perhaps you work with multiple monitors so you’d like the displays to show the same level of brightness across all of them for consistency.

Another reason you may want to adjust or turn off adaptive brightness is if you need a specific screen brightness in a particular setting. When you’re working in a dimly lit room, you’ll likely want your computer’s brightness to be set lower so you can continue to work without hurting your eyes. On the other hand, if you’re working outside, you’ll need the screen to be brighter so you can see properly.

You can change these settings manually or have Windows change it based on whether or not your device is plugged in, how much battery power you have left, or if you’re using an ambient light sensor built into it.
