How to Adjust Brightness on Pc Using Keyboard?

Hey there! Adjusting the brightness on your PC using the keyboard can be super quick once you get the hang of it. Just a heads-up: it might differ a bit depending on whether you’ve got a laptop or desktop, and different brands play by their own rules. Let me walk you through it.
First things first, hunt down those brightness keys. They’re usually hanging out in the function key row at the top (F1-F12) or chilling as bonus functions on other keys. Look for icons that resemble a sun or something bright—the sunny ones!
- Get brighter: Typically marked by a sun with rays or just a big bright sun.
- Dimmer time: Look for a darker sun or one with fewer rays.
Take ASUS laptops as an example—you’d hit the Fn key along with F7 to lower brightness and Fn + F8 to pump it up. Got an HP? You might be rocking F2 and F3 for the dim and the bright.
Here’s the kicker—pressing those brightness keys usually needs you holding down the Fn key. It’s lurking somewhere at the bottom left corner of the keyboard.
Moving on, if you’re using a desktop without those handy-dandy brightness keys, you’ve got a few other tricks up your sleeve:
- Monitor Magic: Most monitors let you mess around with brightness using their buttons. Dive into the on-screen menu and light things up.
- Windows Wizardry:
- Hit Windows + I.
- Cruise over to “System”, then “Display”.
- Find the slider for brightness and color, then slide away!
Oh, and here’s an easy one: you can fiddle with brightness through the Action Center. Give the icon a click—it’s over on the taskbar looking like a speech bubble—and you’ll see a brightness slider. Slide it left to dim or right to glow.
What really matters is to keep in mind that not every keyboard is equipped with these keys—especially on desktops where monitor buttons come to the rescue.
So, there you go. Hold the “Fn” key, mash on those sun-adorned function keys for laptops, or go through monitor buttons and Windows settings for desktops. You’ve got the power to light up or tone down your screen brightness, all with a few taps.
Now that you’re clued in, happy brightness tweaking!

Looking to tweak your PC’s screen brightness with just your keyboard? Here’s a quick and friendly guide to help you out. It’s a nifty trick that can save you from poking around in menu after menu. Plus, with the right settings, you’ll be giving your eyes and battery a break. Almost all modern keyboards come with this functionality built right in!
Alright, let’s dive into how to do this for both Windows and macOS.
For Windows PCs
Those little sun icons on the F1-F12 keys? Yep, those are your go-to buttons. On most laptops, you’ll find them on keys like F5/F6 or maybe F2/F3.
- Here’s how you get to it:
- Find the little sun icons on your keyboard.
- Hold down the Fn key and press the relevant brightness key. For instance, tap Fn + F5 to dim things down or Fn + F6 to brighten it up.
- Sometimes you won’t even need the Fn key. Handy, huh?
- If those keys don’t want to cooperate:
- Hit up the Action Center and find the brightness slider—usually lurking in the taskbar.
- Head over to Settings > System > Display and tweak it from there.
For macOS
Got yourself an Apple keyboard? Things are pretty straightforward:
- To brighten things up: Hit F2 or the key with a sun icon pointing upwards.
- Tone it down: F1 or the sun icon pointing downwards.
- If you’ve got one of those fancy Touch Bar MacBooks, just slide your finger across the brightness slider there.
When Things Go Haywire
Sometimes those brightness keys act up, and here’s what you might be dealing with:
- They’re just not working? Could be down to outdated drivers or some funky power settings. Here’s a quick fix:
- Dive into Device Manager, look under Keyboards or Monitors, and update those drivers!
- Check your power settings over at Control Panel. Make sure brightness adjustment isn’t sneaking off under display settings.
- Function keys being rebellious? Maybe the Fn Lock is on, and you’ll need to toggle it off. It’s usually on the Esc key or floating around somewhere nearby.
Extra Little Tips
- Turn on auto-brightness through Settings > System > Display. It lets Windows do the heavy lifting based on ambient light.
- For those gaming PCs, NVIDIA Control Panel or AMD Radeon Settings can help you fine-tune the display.
Once you’ve got the hang of it, managing screen brightness and fixing any issues you bump into will be second nature. If you find yourself stuck, check out the manual or hit up the manufacturer—they usually have it all figured out for your specific model.

Want to crank up or tone down the brightness on your PC using just the keyboard? It’s actually pretty straightforward! Let’s dig into a few tricks.
First up, those function keys you see on your laptop might be just what you need. They often look like little suns and usually work when you press them alongside the Fn key. For example, you might hit Fn + F5 to dim the screen or Fn + F6 to brighten it up. This varies depending on the brand, so have a quick look around your keyboard.
Moving on, Windows 10 and 11 users have a neat trick up their sleeve. Hit Windows + A, and bam! You’re greeted by the Action Center where you can easily slide the brightness level to your liking.
Now, if your keyboard’s not playing ball with these shortcuts, there’s no need to worry. Some third-party apps like Twinkle Tray can save the day. Just grab it from the Microsoft Store, set it up, and you’ll be customizing your brightness with new shortcuts in no time.
For the tech-savvy folks, poking around in the Graphics Control Panel might reveal some hidden brightness settings. Intel users can check out their Intel Graphics Command Center, while AMD and NVIDIA users should look into their respective panels.
If all else fails, here’s a classic move: Press Windows + X and navigate to the Mobility Center. This gives you a straightforward slider to tweak the brightness to your heart’s content.
And there you have it—a host of options to keep your screen’s brightness just right. So, pick whichever method speaks to you or your setup. If you’re scratching your head, your computer’s manual or the Windows support site might have some golden nuggets of wisdom.
Happy adjusting!
