screen dimmer windows 10

If you’re looking for a way to dim your screen, there are a few different options available to you. You can adjust the brightness in Windows 10, use the f.lux app, or even adjust the screen brightness in the BIOS.

Additionally, there are a number of screen dimmer apps available that can help you achieve the perfect level of screen brightness for your needs.

How to Dim Your Screen in Windows Using Windows 10’s Brightness Settings.

In Windows 10, you can adjust your screen’s brightness settings in two ways: through the action center, or by going to Settings > System > Display.

To adjust your screen’s brightness through the action center, first, click the Notifications icon in the bottom-right corner of your screen. This will open up the action center. Then, on the Brightness tile, click. You’ll see a slider that you can use to adjust your screen’s brightness.

To adjust your screen’s brightness through the Settings app, go to Start > Settings > System > Display. Then, use the slider under “Change brightness” to adjust your screen’s brightness.

Adjusting the Screen Brightness in the BIOS.

The BIOS is low-level software that starts when you turn on your computer before booting into an operating system like Windows 10 or macOS. You can change the brightness or dimness of your computer’s display in BIOS without using any additional software.

To change this setting, restart your computer and press a key (usually Delete, F2, F10, or Esc) to enter iOS. Once in BIOS, find a setting called “Brightness” or “Backlight” and use the + and – keys to increase or decrease its value until you find a comfortable setting for you. Save these changes and exit BIOS; when you boot into Windows 10 again, you should see that your display is now dimmer (or brighter) than before.

Accessing Brightness Control From The Desktop

You can adjust the brightness of your monitor by accessing the settings menu on your computer. To do this, right-click on the desktop and select “Display Settings.” Under “Brightness and Contrast,” use the slider to adjust the brightness of your screen. You can also access this menu by going to “Control Panel” > “Appearance and Personalization” > “Display.”
