Here’s How to Manually Change Your Windows 11 Display Brightness
Windows 11 lets you manually change your screen brightness through simple methods. Adjusting brightness helps make your screen easier on your eyes or lets you see it better in bright rooms.
You can find a brightness slider right in the Quick Settings menu. Press Windows key + A to open this menu and easily slide the brightness up or down.
For more options, you can go to the main Settings app. Go to Settings, then System, and finally Display. Here, you’ll find the same brightness slider plus extra settings to fine-tune your display’s colors.
You can change Windows 11 display brightness via the Quick Settings panel by clicking the Wi-Fi, sound, or battery icons on the taskbar and adjusting the sun slider. Alternatively, go to Settings > System > Display and use the brightness slider there.
Why Change Screen Brightness?
We adjust screen brightness to keep our eyes comfortable. Excessive brightness can feel harsh, particularly in dim surroundings. If it’s too dim, seeing your screen clearly becomes a challenge. Finding the right level aids visibility and helps prevent eye strain.
What Happens When You Change Brightness?
When you adjust the brightness slider, you alter the amount of light your screen emits. Increasing brightness means the screen outputs more light. Dimming it reduces light output. This makes your screen easier or harder to view, depending on your requirements and the ambient lighting.
Quick Way: Adjust Brightness from the Taskbar
For many users, especially those with laptops, this is the fastest method.
Step 1Open Quick Settings
To change your Windows 11 brightness, begin by opening Quick Settings. You can find this by clicking the icons for Wi-Fi, sound, or battery, typically located near the clock on your taskbar. This panel offers swift access to frequently used settings.
Administrator privileges, which are special permissions to make changes affecting the entire system, are required. A restricted user account will need these administrator privileges to adjust Windows 11 display brightness.
Step 2Find the Brightness Slider
Once Quick Settings is open, locate the brightness slider. It often has a sun icon nearby, enabling straightforward control of your Windows 11 brightness. If it’s not visible, don’t worry, as another method exists for adjusting your screen’s brightness.
The Windows 11 display brightness slider might not appear on all computers, particularly desktops that use external monitors. In cases where the slider is absent, users can access the Settings app to adjust screen brightness.
Step 3Adjust the Brightness
Click and drag the circular control on the slider. Moving it left dims the screen; moving it right brightens it. Fine-tune it until your screen’s appearance and feel are just right.

Detailed Way: Adjust Brightness in Windows Settings
If you can’t find the slider on the taskbar, or wish to explore further display settings, use the Windows Settings app.
Step 1Open Windows Settings
Click the Start button (the Windows logo) on your taskbar. Then, click the gear icon for Settings. Alternatively, press Windows key + I on your keyboard simultaneously.
Step 2Go to Display Settings
Within the Settings app, select System from the left-hand menu. Afterward, click on Display.
Step 3Find the Brightness Slider
Should the brightness slider not appear in Quick Settings, you can find it within the main Windows 11 Settings app. Navigate to the ‘Display’ page within the Settings app. This offers another accessible location for managing your screen’s brightness.
A note for desktop users: If you’re using a desktop computer with an external monitor (a separate screen linked to your PC), you probably won’t find a brightness slider in this location. External monitors come with their own brightness controls. Use the buttons provided on your monitor.

Step 4Adjust the Brightness
To adjust your Windows 11 display brightness, click the slider you located and drag it either left or right. Moving it one direction will dim the screen, while moving it the opposite direction will increase its brightness. This allows you to set the screen to your preferred illumination level.

Summary
You can adjust your Windows 11 screen brightness using either the Quick Settings panel on the taskbar or the Windows Settings app. This helps make your screen comfortable to view in any lighting, reducing eye strain and improving your overall experience.
