How To Fix Screen Brightness Won't Change | Fix Brightness Problem In Windows 11/10

Are you unable to adjust screen brightness in windows 11/10? or does your screen brightness automatically getting reduced and increased? You can fix these two problems easily by two simple methods.

Can't adjust brightness on Windows 10? Here's how to fix it
Adjusting the brightness of our devices has become an easy task we perform every day. Upping the brightness during the day makes it easier to see what’s on the screen. Similarly, at night, you can lower it to allow your eyes to rest.

However, there is an error in Windows 10 that doesn’t allow you to adjust the brightness of your screen at all. This can quickly become annoying, especially if you regularly tinker with the setting.

Re-enable your PnP Monitor
This method works for PnP monitor users. PnP means “plug and play,” allowing you to use your device without installing any drivers.

The issue itself is that some driver or system updates might disable your monitor in the Device Manager. The cause of this is unknown, but it’s good practice to check if it happened to you.

If you’re using a generic PnP monitor, you might be able to solve Windows 10’s brightness issues by following the steps below:

Press and hold the Windows key, then press R. This will launch the Run application.
Expand Monitors by clicking on the arrow icon.
Right-click on your PnP monitor and choose Enable device.
Restart your computer and try adjusting your brightness again.
Still no luck? Make sure you read the next section as well for another solution.

Delete hidden devices under PnP Monitors
Similarly to the last method, this one only works for PnP Monitors. If you’re using one of those, follow the steps below to potentially fix your brightness issues:

Press and hold the Windows key, then press R. This will launch the Run application.
Delete hidden devices under PnP monitors
From the Device Manager’s menu, click View, then choose Show hidden devices. If you already have this enabled, keep it on.
show hidden devices
Expand Monitors by clicking on the arrow icon.
Right-click every hidden device and choose the Uninstall device. (Hidden devices appear more translucent than normal ones, see picture.)
Restart your computer and try adjusting your brightness again.

I guess I'm part of the 1%. Tried the last method and still didn't work.

[e.i.a.]

Thank you very much, you are very detail oriented and specifics are clear and easy to follow....certainly I am going to try this option because I tried everything else and it didn't work. Keep the good work and willingness to help others as us. Your areas of expertise are excellent, take care!

Thanks, second method worked. I was so frustrated since my computer's battery goes down really fast when the brightness is all the way up, you legit saved me from a few days of confusion and frustration

[Kaye_G]

Hi! I have done all these but the bar for adjusting my brightness is still nowhere to be found (not even under System). Anything else I can do to fix this? Thank you so much!

[nazura]

I was wondering what went wrong so thank you so much for this!!

[randolphjaywilliams]

Thank you, thank you! The most important was that you were speaking slow enough for me to be able to follow your instructions on what to do I don’t like other YouTube Computer Tech individuals! That’s especially important since I’m 95 years old. You’re the best and thank you again!

[imahazelnut]

Thank God, the second method worked. I have an exam due at midnight and my screen was so bright it hurt to look at. Thank you 😊

[elijacks]

I commented two years ago that your video was the only one that worked. I just reinstalled windows and had the exact same problem again, and have spent the last two hours trying to find this video again. And it worked. Again. So thank you again! I still love you!

[vladcowl]

Mine was already able but I did the update, at first the brightness went so low I could barely see my screen but then I restart the computer and it worked perfectly! THANK YOU SO MUCH YOU SAVED MY LIFE

[TinaMarie]

Thank you for this! Was wondering why my screen brightness adjustment wasn't working anymore, searched for a solution, found your video, and the second method worked! Thanks! 😊

[cyrusmaina]

You are a life saver. It actually worked. The second method. Thanks and may you be blessed, was already getting worried

[zayn]

Thank you! It worked. Highly recommended to anyone who encountered the same problem as mine. Thanks sir!

Still helping people after 9 month. Thank You Brother ❤️❤️❤️

[GN-Aaron]

Thank you so much! I was so scared that something was wrong, and I just needed to update my built-in graphics card's driver. You're the best! <3

2 years later, 2nd method did the job, thanks man

[faithc.]

Thank you so much 😭😭 I've been looking for effective tutorials all day and i have an exam tomorrow i have to study 😭 this was effective 😭 I'm so grateful 😭

[aguynamedlynx]

I have done the second method and the brightness is working properly again, thank you!

May I ask why such a thing would happen in the first place? Why would the brightness function sometimes just stop working?

[shilver_shadows]

Thanks for this Video, I have had a very painful week. I almost was getting severe RSI due to my screen brightness. This has been very helpful to me.
