Changing the brightness on a Windows 10 computer is a simple task that can greatly improve your viewing comfort. You can adjust the brightness through the settings app, action center, or by using keyboard shortcuts. Here’s a quick overview: Go to the Action Center, click on the brightness tile, and use the slider to adjust to your preference. Alternatively, use the keyboard shortcuts, often found as sun icons on your function keys, to increase or decrease brightness.
How to Change Brightness on Windows 10
In this section, we’ll guide you through the easy steps to adjust your brightness on Windows 10. Whether you’re working late at night or trying to see your screen better in bright light, these steps will have you covered.
Step 1: Open Action Center
Click the Action Center icon in the bottom-right corner of your screen.
This is where you can quickly access various settings, including brightness. It’s a handy tool for making fast adjustments without diving deep into the settings menu.
Step 2: Adjust Brightness Slider
Find the brightness slider and move it left or right.
The slider is intuitive; dragging it to the left will dim the screen, while moving it right will brighten it. This lets you have real-time control over the brightness level.
Step 3: Use Keyboard Shortcuts
Press the brightness keys on your keyboard, usually F1 or F2.
If your device has dedicated keys for brightness, they often have sun icons. These shortcuts provide a quick way to adjust brightness on-the-fly, especially if you’re in a full-screen application.
Step 4: Access Settings via Start Menu
Open the Start Menu and go to Settings > System > Display.
For more precise adjustments or troubleshooting, the Settings app provides comprehensive options. From here, you can also manage your display settings more thoroughly.
Step 5: Adjust Night Light Settings
In the Display settings, turn on Night Light for evening use.
Night Light reduces blue light emission, which can help reduce eye strain during nighttime use. You can schedule it to turn on automatically at sunset and off at sunrise.
After following these steps, your screen brightness will be set to your desired level. This can help reduce eye strain, improve visibility, and even save battery life on laptops.
