Adjusting the display settings on a new computer is easy to do. It's important to know how to adjust the brightness on Windows 10 and Windows 11 because if you get eye strain or headaches, the display brightness could be the culprit. Fortunately, you can adjust the levels manually or automatically based on parameters like battery life or the surrounding light.

If the slider is unavailable, it will be due to one of two things. If you're using an external monitor, use the buttons on that to change the brightness. Otherwise, you need to update the display driver.

If this applies to you, consult your monitor's documentation for guidance on adjusting the brightness because the exact instructions will vary per monitor. You should have buttons on your monitor that bring up an on-screen display, which you can navigate through to alter the brightness.

Your display driver manufacturer will have its own control panel from where you can control brightness. For example, there's the Intel Graphics Control Panel and the NVIDIA Control Panel. Which one you'll use or have depends on what graphics card you have.

Lowering your brightness can help you squeeze more juice from your portable device's battery. Windows 10 and Windows 11 have a battery saver feature that limits notifications and background activity, and this can also automatically lower your brightness.

Ideally, your monitor brightness should match the surrounding light since this reduces eye strain and unnecessary battery drain. One way to help with this is to have the brightness automatically change based on your ambient light.

The exact key combination will depend on your keyboard model. For example, you may need to hold down or activate the Fn key and then press the corresponding function key simultaneously.

You can quickly adjust the brightness through the Action Center icon in the taskbar (or press Win + A.) Then, use the brightness slider to adjust the level. The further right the slider, the brighter the screen.

Want a good third-party utility? Check out the Windows 10 Brightness Slider. Despite the name, it works on both Windows 10 and 11. This lightweight utility will add a brightness icon in your system tray, which you can then click to adjust your brightness on a slider, much like how the volume icon works.

Head over to the GitHub project, download the file, and open it. It'll automatically go into your tray. If you want it always to be there, right-click the icon and click Run At Startup.

With brightness sorted, you may want to check out your monitor's color temperature. The light from our screens apparently causes sleep problems, and thus you can use programs like f.lux or Windows's Night Light feature to help combat it.

I have a Dell XPS 13 (9350) running Windows 10 and I can't seem to disable the automatic brightness changing depending on what's on the screen. If the screen is primarily light the brightness will go up, and when it's primarily dark it'll dim. I'm having the same issue as outlined in these posts:

but none of the solutions given worked for me. In my Intel HD Graphics control panel there is no "Display Power Saving Technology" option, nor are there "On Battery" or "Plugged In" tabs in the power section. This problem persists on both battery and AC.

For me I had to disable it by right-clicking on the desktop and choosing "Intel(R) Graphics Control Panel" (it's only accessible from the desktop, not the Start Menu). "Power", "Display Power Saving Technology", "Disable". Hope that helps someone.

Intel Display Power Saving Technology (DPST), sometimes called "adaptive brightness", is a feature of some Intel graphics chips that automatically adjusts the screen brightness based on what is shown on the screen.

On Desktop PC, Nvidia gtx 1060, after a full day of trying to change the windows 10 power settings and after searching for registry solution on the net to stop changes in brightness depending on the screen contents and after a full day trying to solve this anti-usability "feature" , poor PC display stability due to this stupid auto-brightness, auto-dynamic-contrast , Adaptive Brightness persisted. lost a full day with settings, registry tweaking and so on hoping to solve this issue and to disable Adaptive Brightness, Adaptive Contrast .

I finally found a fix for this. The setting is in the "Intel Graphics Command Center", which you can hopefully find by searching under the Start Menu. In the Command Center, hit the System tab on the left (the one with 4 boxes), and then click the Power tab at the top. Turn all this stuff off. Or just turn off the "Display Power Savings" option - that's the one that dims the screen when dark content is shown.

It also takes controls from the monitor itself (including built-in ones), so if your device came pre-installed with Windows 11 or the monitor is able to give commands to the OS, then the built-in sensors will change the brightness as needed - much like on smartphones.

Is your PC monitor too bright or too dim? You can easily adjust the screen brightness of your Windows 10 computer in the Settings menu. You can also change the screen brightness in the action center in the taskbar. This wikiHow guide will show you how to adjust the screen brightness in Windows 10.

For the Fn + F5 (its F5 on my computer, might be different on yours) to change the brightness you have to have the Samsung "Easy Display Manager" installed. Check to see that the program is still installed. If its not installed goto the Samsung website look up the model of your computer and it will display all the software dowloads that were pre-installed on your model of PC, if you need to you can download the "Easy display manager" again, once installed reboot you system and Fn + F5 should work again.

I am not sure I fixed everything, but I am finally able to adjust my brightness. I used my model number, NP88OZ5E and went to the Samsung website. I downloaded SW update and used it to download a myriad of new drivers and updates. It took quite a while. I still can't use my Fn keys to adjust brightness (I am missing that "easy display manager" program you referred to and I can't figure out how to find it, though I looked), but it works now when I use the control panel to adjust brightness now.

Thanks for all the help with what I am sure is normally very basic stuff. I feel a little smarter now at least. If you have any more suggestions for me, I am happy to hear them. If not, then thanks again.

I have a Samsung N210 Plus laptop which developed the same problem you were having,no brightness control. This happened a few years ago. The LCD display was on full brightness all of the time, which made using it uncomfotable on my eyes. This appears to be an issue with Samsung. The problem started just after the guarantee had expired. I also tried all different ways to sort the problem out, nothing worked. I contacted Samsung and spent over half an hour on the telephone, with a technician. We got the brightness control working. Next time I switched on the laptop it had gone back to full brightness with no conrol. I stopped using the laptop until I found out about f.lux. This program auto adjusts the brightness, you can also manually adjust the brightness with ( Alt-PageUp or Alt-Page Down).

My problem was the same: all Fn buttons had worked fine, except brightness buttons. All the same I was not able to change the brightness in windows control panel (brightness adjustment was missing) and in samsung control center (nothing happened when moved the brightness adjustment).

Check programs that can "override" your screen. My problem was TeamViewer 13. Don't know how TeamViewer had been overriding brightness settings, but when I had deleted it, Fn-buttons for brightness were on.

I tested out the theory today when connecting the displays to a Windows PC. Prior to connecting the Windows PC, I set the brightness of each display using my Mac. Then I unplugged the Mac and plugged up the PC. Sure enough, the brightness remained at the same level as previously set using the Mac. Woohoo!

The issue remains that I cannot change the brightness directly on the Windows PC itself (don't think that's doable - or at least not yet). If I wanted to change the brightness, I'd have to hook up the Mac again, change the brightness to the desired level, and reconnect the PC. So you're stuck needing a Mac one way or another! Also tried connecting an iPad Pro to see the brightness could be changed that way, but that didn't work either... and funny enough I would imagine that an iPad would be capable of doing this considering it's an Apple device running the latest iPadOS.
