Whether you’re using a laptop or a desktop PC, you’re likely going to want to change the brightness of your favorite display from time to time- or pretty frequently, if you use a laptop for work in a variety of locations. While it’s easy enough to change brightness directly on your display, that’s not an option for laptop users, and even those using dedicated displays with desktop PCs may want other options for image control.


  • Setting brightness correctly can help reduce eye strain for long work periods
  • Windows 10 offers plenty of options for adjusting brightness on desktop PCs, laptops, and tablets
  • Laptops and tablets offer customizable power-saving modes that automatically adjust brightness

Thankfully, Windows 10 offers a number of ways to control brightness without touching your display’s built-in controls- and laptops and tablets even allow Windows to automatically adjust the brightness based on battery power. Below, we’ll walk you through all the ways you can control brightness in Windows 10, and why brightness settings matter.

Brightness and Eye Strain

Working long hours in front of a display that’s either too bright or not bright enough can seriously increase eye strain, which can permanently affect vision over the course of several years. Other settings, like contrast, gamma, hue, monitor viewing angle, and vibrance can also contribute significantly to eye strain, but brightness is the first factor one should consider when setting up optimal display settings.

How to Adjust Brightness Manually on a Windows Laptop

Most laptop keyboards have shortcut keys you can use to increase and decrease screen brightness. Usually, they’re on the same row of keys as the numbered “function” keys (F1-F12). These keys will usually be labeled with an icon- a sun logo or a similar image, one for increasing brightness and one for decreasing it. Sometimes, these will be function keys themselves, meaning you’ll have to press and hold the “Fn” key simultaneously. The “Fn” is most often located on the bottom-left corner of the keyboard. Be sure not to manhandle your laptop while looking for the shortcut keys, especially if you do not have computer insurance.

Using Windows Power Mode Settings for Laptops and Tablets

Windows laptops and tablets have a feature for managing battery use that will automatically dim your display when your device needs to save power. To access it, press the battery icon in your device’s system tray.

Scroll down to the “Battery saver” tab and check the box next to the “Lower screen brightness while in battery saver” option. Move the slider all the way to the left over the “best battery life” option. When running off battery power, your display will automatically dim when your battery is low. The slider also allows you to choose the battery percentage at which the feature turns on. You can also check out how to change monitor brightness if you do not have a windows 10 computer.
