Download Brightness Controller For Windows 10 !!HOT!!

Some PCs can let Windows automatically adjust screen brightness based on the current lighting conditions. To find out if your PC supports this, select Settings > System > Display. Under Brightness and color, look for the Change brightness automatically when lighting changes check box, and then select it to use this feature. This automatic setting helps make sure your screen is readable wherever you go. Even if you use it, you can still move the Change brightness for the built-in display slider to fine-tune the brightness level.
The Brightness slider appears in action center in Windows 10, version 1903. To find the brightness slider in earlier versions of Windows 10, select Settings > System > Display, and then move the Change brightness slider to adjust the brightness.
Windows only displays its built-in monitor brightness controls on laptops. Historically this has been because desktop monitors tend to have physical brightness controls already (though some don't, thank you Apple) and based on my own personal experience some monitors have unreliable DDC/CI implementations.
But that was in the past. Presently the DDC/CI interface on all of my current monitors seems solid - so I want to get Windows to allow me to control monitor brightness using Windows' built-in brightness controls (from the Action Center sidebar, keyboard hotkeys, and the Settings app) instead of using random DDC/CI apps from the Internet.
All of my monitors fully support Windows' VCP Monitor Configuration API (verified by using a VCP API developer tool) so I assume there must be some configuration option or setting in Windows that tells it to show or hide the brightness controls, but where is it?
Update: Based on my reading of the Windows HDK documentation for hardware brightness controls, it requires close cooperation of Windows' own "monitor driver" (monitors need drivers?) and the GPU's driver (NVidia, AMD, Intel, etc) with Windows: i.e. Windows' built-in brightness sliders seemingly always go through the GPU driver, as the expectation is hardware GPUs have control over integrated displays, so it doesn't seem possible for third-party applications to hook into this process.
Respected Windows 11 Team,
2 days ago, I updated to Windows 11 23H2 25921.1000 as a member of the Dev Channel. Since then, the Brightness Slider on my desktop isn't working. I have to reinstall the Intel Graphics Driver for UHD 630 and the brightness issue gets resolved but every time I restart my laptop, the same issue persists until I reinstall the Intel Graphics Driver again. This is becoming a hassle since I have to install Graphics Driver again and again. The previous one gets corrupted or something.
As a side note, the issue of desktop icons becoming blank after some time still isn't resolved. With this update, things have worsened.
Thank You
I just upgraded my Mid-2009 15-inch Macbook Pro from Windows 7 to Windows 10 and the Bootcamp drivers for controlling the brightness no longer work. I tried reinstalling Bootcamp but because Apple doesn't officially support anything higher than Windows 7 on my computer I cannot reinstall it. I tried installing individual drivers such as the keyboard and NVIDIA but nothing has fixed the issue. Other keyboard shortcuts (ie volume, keyboard brightness) still work. I am not even able to change the brightness using the brightness slider in the Bootcamp menu in the taskbar (it will still slide and I can Apply changes, but it doesn't actually make any changes). The only thing I've found that works is to open the NVIDIA icon in the taskbar and choose to modify brightness with that directly, which is very inconvenient considering I can no longer adjust brightness using the F1 and F2 keys. I've read a lot of other posts but none of the solutions I've found worked (mostly all say reinstall bootcamp drivers). Does anyone know how to make it so the brightness controls on the keyboard work again? Thanks for any input.
You can't, because your Mac does not support Boot Camp 6, and it provides the drivers needed to manage brightness and volume through the keyboard (these ones can only be installed through the official Boot Camp installer, not installing the drivers individually).
No, ALL of the keyboard shortcuts WORK with the exception of the brightness control (which doesn't even work manually adjusting in the Bootcamp app). Bootcamp is still installed, it is just that the brightness control stopped working with the upgrade and I cannot reinstall. Undoing everything and using a virtual machine is NOT a solution for me - I would sell my MacBook and buy a Windows only machine before that (I stopped using the OS X side awhile ago because everytime they update it seems the only point is to add integration with IOS devices (which I don't have) and it results in my computer slowing down.) A native experience is by far better than any emulation, even with it being slowed artificially by Apple because they forced Windows to install on an emulated BIOS for my particular model.
As the above from previous posts indicate, I know that Bootcamp is not supported: I am looking for alternate options. Right now I am still using the NVIDIA controls and I calibrated my screen using the NVIDIA controls for brightness and contrast during the process. This is still a clunky bandaid instead of a good fix, but it makes the computer usable. Please if anyone knows something else that works, post here.
The software at the link below, Dimmer, can used to dim the screen further than I can with the NVIDIA controls. It is also very simple and stays in the taskbar (so it is not a pain to quickly change brightness settings). It is also free, the developer just requests donations.
The "Microsoft Basic Display Adapter" solution worked, but hardware acceleration features were gone. I followed -unchangeable-in-windows-8-on-a-macbook-wi th-nvidia/, I switched back to an nVidia driver and added the registry entry "EnableBrightnessControl" set to 1, as decribed in the page. Now I have brightness control and a real nVidia driver.
I'm having an issue with my Samsung N210 laptop that has the GMA3150 graphics controller (Atom N450 CPU). The problem is that after downloading recent Intel graphics drivers I can no longer change my screen brightness. This problem has been reported long ago elsewhere, at least in the sammynetbook.com forums. Following their advice, I uninstalled the driver and went back as far as version 8.14.10.1972 (the 64-bit version of the driver). The next driver available from Intel's site no longer allows me to change screen brightness, nor does anything newer.
Now, screen brightness on the N210 netbook is controlled by pressing Fn + Up and Fn + Down. It also requires a program from Samsung called "Easy Display Manager". Trying to adjust screen brightness using the latest Intel driver bring up a graphic produced by Easy Display Manager (EDM from now), but the brightness bars in said graphic don't move, nor does screen brightness change.
The problem is not just with Samsung's EDM program. There is a brightness slider in Windows 7 Power Options, and that also doesn't work after installing a driver later than .1972. With .1972 the Windows screen brightness slider works again, just like Samsung's EDM.
What is causing all of this and is there any way to use drivers less than a year old while still being able to control screen brightness via hotkeys? It's an important feature of any laptop. It just HAS TO WORK, don't you think?
This driver is the one Windows Update is pushing onto my netbook in Windows 10. Like all the other complaints above, it won't let you change the brightness of the backlight, so you drain your battery faster when not plugged in.
Now that it's morning, I've had some time to go through line-by-line those added registry keys. I can confirm that I can still control the brightness after removing all the "added" entries above. You only need to change the number value for the FeatureTestControl values to make it work.
But it did NOT change on the 0001 key (HKLM\SYSTEM\ControlSet001\Control\Class\4d36e968-e325-11ce-bfc1-08002be10318\0001). I think once I changed THIS one and rebooted, the system suddenly responded to brightness commands.
Because I have read that sometimes the FFFF value might prevent the screen from even turning on after recovering from Standby ( -8/samsung-n150-plus-i-cant-control-bright/701.html Samsung n150 Plus, I can't control bright), I have changed the values to FFFE and I still have brightness control. I tested my Sleep mode just now and with the FFFE value in all positions, it does in fact come up properly after Sleep. I have Hibernate mode disabled for personal reasons. I don't much care for hibernate. Windows 10 boots up fast enough on its own for me to not care. I am running a Crucial MX100 250 GB SSD drive, after all.
You can even do like apastron said and make a registry batch file to do this. Make these three changes and then reboot your computer. You should have brightness control back if you have the Samsung Easy Display Manager software installed. You can get that app from Samsung's website for the N150 ( -N150-JA03US -N150-JA03US).
EDIT: Ok, so the Brightness keys work just fine, but something that still doesn't work are the Brightness sliders in Windows itself. Because of this, the brightness doesn't auto-change when you unplug the power supply and move to battery power and vice versa. I'll continue working on this issue until I have a solution.
So I'm still testing different values and registry settings, because even using FFFE, the Windows sliders still don't work. Yes, the FN keys change the brightness just fine. But I want to get the Windows sliders working so that when I plug/unplug the power cable, the brightness will automatically change to fit the change in power profile. To do this, I'll have to really study the entire registry log for that chip in Windows 7 so I can replicate it to Windows 10. I'll keep this thread updated with any progress I make.
