How To Fix Screen Brightness Fluctuations in Windows 11

Update Your Graphics Drivers

This one’s probably the most common fix I’ve come across — flickering screens or brightness constantly shifting are often just outdated or incompatible graphics drivers acting up. Honestly, it’s not just a casual tip; I’ve seen this cause weird display behavior more than once. The trouble is, finding where to update drivers feels like a scavenger hunt sometimes. The first step is to head into Device Manager — which, by the way, is hidden in the most awkward spots depending on your Windows version. You want to expand “Display Adapters”, then right-click on your graphics card device and choose “Update Driver”. Be aware: Windows might find an update for you, but often it’s not the latest version. Better approach? Go straight to the manufacturer’s site—be it NVIDIA, AMD, or Intel—and download the latest drivers there. This step really made a difference for me, especially if the flickering was relentless. Sometimes, Windows’ auto-updater isn’t enough, and you need to grab the driver manually, run the installer, and restart. Yeah, it’s extra work, but worth it to get rid of the brightness dance and weird flickers. Just don’t forget to double-check after reboot—sometimes you need to reinstall or repeat the process if things aren’t stable yet.

Disable Adaptive Brightness

If updating drivers didn’t fix everything, then Windows’ own setting might be the culprit. The ambient light sensor (or so it claims) automatically adjusts your brightness based on lighting conditions. Cool idea, right? Except it can be super annoying, especially if you’re in an environment where the light fluctuates or you move around a lot. To turn this off, press Windows + I to open Settings. Then go to System > Display. Look for the section called “Brightness and color”. There, you should see a toggle labeled “Change brightness automatically when lighting changes”—or similar wording. Sometimes, this option is hidden under Additional display settings or in a sub-menu, so be prepared to hunt around a little. Turning this off will let you manually control the brightness without Windows messing around. Drag that slider to your preferred level, then forget about it. For me, this was a key step because even after updating drivers, Windows kept surprising me with auto-brightness changes. Once I disabled it, the brightness stayed put—like it’s supposed to.

Turn Off Intel Display Power Saving Technology

If your PC is rocking an Intel CPU with integrated graphics, there’s another sneaky feature called Display Power Saving Technology. Basically, it’s designed to save power by messing with your brightness — even if it means flickering all day. Default settings enable it, which is frustrating when all you want is a steady screen. To disable, search for the Intel UHD Graphics Control Panel — or install the Intel Graphics Command Center from the Microsoft Store if you haven’t already. Once it’s open (probably via the system tray or Start menu), look for the Display or Power tab. Within there, find the Display Power Saving Technology option and turn it off. Just hitting that toggle made a huge difference for me. It’s like Intel’s trying to save watts at the expense of stability, but I’d rather have a consistent brightness than flickering all day. You’ll need to dig into these settings because, honestly, they don’t always appear obvious right away.

Turn Off Battery Saving Options for AMD and Intel Graphics

For those using AMD graphics or other system-wide power-saving features, similar issues can crop up. On AMD cards, open the Radeon Software. Previously known as Adrenalin Edition, it typically houses settings that tweak your display brightness depending on whether you’re plugged in or on battery. When unplugged, it might automatically dim your display without you realizing. To fix, right-click your desktop, select AMD Radeon Software, and then go to Gaming > Display. Look for options like “Vivid” or “Brightness Enhancer” and toggle those off. Sometimes, you’ll find similar controls under the Display or Power menus within that app. Same idea if you’re running Intel graphics — open the Intel Graphics Command Center (search from the Start menu or right-click on your desktop). Then check under System > Power > Battery Settings for features like “Display Power Savings” and turn those off. The struggle is real — these settings can hide in weird corners and change with driver updates, but disabling them is usually the fix. I went through quite a bit of trial and error before my brightness settled down.


Honestly, fixing fluctuating screen brightness in Windows 11 isn’t exactly straightforward. Driver updates, hidden settings, BIOS options — all can play a part. It’s kind of a pain to figure out what’s causing it, and sometimes you have to reboot a few times or recheck settings after updates. But once everything’s dialed in, it makes life way easier. I hope these tips help because dealing with a flickering or inconsistent screen is beyond frustrating during work or just chilling out. Every machine seems to have its quirks, and Windows’ endless tweaks don’t make it easier. Still, with some patience and the right adjustments, you can finally have a stable display again.

Hope this helped — it took me way too long to get this figured out. To double-check, make sure:

  • Your graphics drivers are fully up to date from the manufacturer’s site.
  • You’ve turned off adaptive brightness in Settings.
  • Any Intel Graphics Power Saving features are disabled.
  • If using AMD, check their Radeon Software for brightness-related toggles.
  • And finally, reboot after making each change—sometimes that’s what it takes for things to stick.

> Anyway, hope this saves someone else a weekend. Good luck!
