Managing your screen brightness might seem like a small thing, but it can make a big difference in how you use your computer. Whether you’re working late at night, trying to save battery life, or just making your screen easier on the eyes, Windows 11 offers multiple ways to adjust brightness. In this guide, we’ll walk you through everything step by step—so by the end, you’ll be a brightness-tweaking pro!
Why Is Screen Brightness Important?
Think of your screen brightness as the dimmer switch in your living room. Too bright? You’ll strain your eyes. Too dim? You’ll squint like you’re reading under candlelight. Brightness doesn’t just affect comfort—it impacts battery life, productivity, and even your health.
- Eye strain: High brightness levels can fatigue your eyes.
- Battery life: Lower brightness means longer battery usage.
- Visibility: Adjusting brightness helps in different lighting conditions.
Ways to Adjust Brightness in Windows 11
There’s more than one way to control brightness on Windows 11. Let’s explore all of them.

This is the easiest and fastest method. Think of it as your remote control for screen lighting.
Step 1: Access Quick Settings

Go to System > Display.
Step 3: Adjust Brightness

- Press Fn + Brightness Key Up to increase brightness.

How to Fix Brightness Slider Not Working in Windows 11
Sometimes, the brightness slider disappears or stops working. Here’s what you can do:
Update Your Display Drivers
- Right-click on the Start menu.
- Select Device Manager.
- Expand Display adapters.
- Right-click your graphics driver and choose Update driver.
Restart Windows Explorer
- Press Ctrl + Shift + Esc to open Task Manager.

How to Save Battery by Adjusting Brightness
Running low on juice? Lowering your brightness can stretch that battery life.
- Reduce brightness to 30–40%.
- Enable Battery Saver mode in Quick Settings.
- Avoid high brightness when streaming videos.
How to Adjust Brightness on a Desktop PC
Desktops are a little different. Most monitors have their own brightness controls.
- Locate the physical buttons on your monitor.
- Press the Menu or Settings button.
- Navigate to Brightness/Contrast settings.
- Adjust using the monitor’s built-in menu.
Set Brightness Using Third-Party Apps
If Windows options feel limited, apps like f.lux or Monitorian can give you finer control over brightness and color temperature.
Common Issues When Adjusting Brightness
- No brightness slider: Likely a driver issue.
- Brightness changes automatically: Disable adaptive brightness.
- Brightness won’t save after restart: Update your graphics driver.
Tips for Optimal Brightness
- Keep brightness around 50–70% for most indoor environments.
- Use Night Light in low-light conditions to reduce blue light.
- Avoid maximum brightness unless under bright sunlight.
Should You Use Night Light Instead of Brightness Adjustments?
Night Light doesn’t change brightness—it reduces blue light, making the screen warmer and easier on the eyes at night. Combine both for the best experience.
How Brightness Affects Your Eyes and Sleep
Bright screens at night can mess with your circadian rhythm—basically, they trick your brain into thinking it’s daytime. Lower brightness + Night Light = better sleep.
Conclusion
Adjusting brightness in Windows 11 isn’t just about preference—it’s about comfort, productivity, and even health. Whether you tweak it through Quick Settings, keyboard shortcuts, or advanced settings, finding that perfect level can make your screen experience a lot better. Play around with these methods and see what works best for you.
