  1. None of this has worked and I do not even have the display brightness or dimmed display brightness options in the workaround method? J just bought a brand new Asus gaming laptop and the screen is so bright I cant even look at it!!! 🙁

  2. Vanessa Faye Magpantay

    I have tried all of this but still it doesn’t work! I can’t do anything to change the brightness level of my laptop. The screen is so bright it hurts my eyes :(((

  3. i have tried every single thing here and on every other website i’ve found that gives tips multiple times and nothing has working. 30% of the stuff that was shown on these windows never even showed up on mine. HELP.

  4. THANK YOU!!!
    I thought my computer was biting the dust because I couldn’t brighten the screen. This fixed it.

  5. My problem was caused by Teamviewer.

    It had installed a driver that overrode the generic PNP. You just need to go to device manager > Monitors. If it is not generic PNP monitor then uninstall the device and driver and then scan for hardware changes.

    That was the fix for me.

  6. My display adapter is not Intel graphics it is showing me Microsoft basic display and am using hp 15 what do u tink I can do to adjust my brighteners

  7. Am facing the problem right now. I have tried all the above meantioned methods, but can’t work. it seems to have only altered the screen resolution. please help.

  8. Is it safe to select “Microsoft Basic Display Adapter” if it doesn’t show up under “Show compatible hardware”? (It only appears if I uncheck that box)

  9. Yes !! this fixed it on my MSI U270-215.
    Installed the Microsoft basic display adapter and it immediately came back to maximum brightness.
    Then I let it search for updated drivers on the internet and it installed the required AMD driver but kept the brightness ok and adjustable !!.

    Furthermore I also had a problem with the AMD AHCI sata driver.
    Did the same trick; installed the generic Microsoft AHCI driver, let it search for updated driver on the internet et voila; also that problem solved.
    Always nice to learn something new 🙂

  10. Hey! So I tried method 1, and while it worked for me, I would say it’s a temporary fix because I couldn’t play games when using Microsoft Basic Display Adapter (graphics was laggy). And after long search on how to actually correct it, I found a way. Sharing it here so that it could benefit others who have similar problems:

    1. If you’re using Intel HD Graphics 4000 like me, try going on their website and download independent driver so that you could update it. (you can also try this if you’re using different ones)
    2. After everything is running accordingly, your brightness can be adjusted.
    3. If it still doesn’t work, try clicking on this link and follow the instructions
    https://answers.microsoft.com/en-us/windows/forum/all/intel-hd-graphics-4000-brightness-fix-solved/488d4baf-ab85-46ad-be78-2fde7ec8522c

    This definitely worked for me and now I could adjust my brightness level while using Intel graphics display. Hope it helps!

  11. This is a very useful article and I’ve bookmarked it – since I need to do these steps every month or so when Windows decides that I shouldn’t be allowed to adjust my own brightness. Two years on, and the bug still hasn’t been fixed.

  12. Disabling and enabling right after the generic PNP monitor works for me, in device manager. You have to restart the laptop after doing that.
