^I had the same problem after updating my graphics drivers, for some reason this "PnP" thing in "Screens" went off and I just toggled it back on and then I could adjust the brightness again.
Hope the picture explains, because I'm bad at explaining in english.

Hello Focke Svain

It looks like the new AMD driver is incompatible with Windows 10, at least for now. Can you please uninstall the new driver and install the older one to check if that works?

If you have updated the driver, you can rollback to its previous version. You can learn how to do so from here.

Hope this helps. Cheers!!

1) Search for Device Manager in Start Menu
2) Expand the Monitors section
3) Right click on Generic PnP Monitor and
4) Click on Enable and you are good!

I also just created an account just to thank you!!

I do have one thing to add: When I clicked on 'monitors' in Device Manager, the PnP was already enabled. Which left me VERY confused. Then I realized that my initial download of my AMD graphics driver after installing Windows 10 was unsuccessful. SO, if someone else's PnP is already enabled and you can't adjust your brightness. Click on 'Display Adapters' in Device Manager. If there is yellow triangle with an exclamation point beside the AMD driver, you'll need to install the new driver (which can be done by right clicking, then choosing for windows to install/update). Once you're AMD driver is installed, it will disable the PnP. Once you enable the PnP, it will all be working smoothly again (or at least it should if you're having the same issue as me).

For anyone struggling to understand these methods, I had the same problem and to solve it I did 2 things, however I'm not sure which one worked. either way, both of them are beneficial to your computer.

1. Update Graphics Card Drivers. (Most recommended)

2. Update Java.

^^^^^^ yup same here... you saved a lot of people's eyes from being blinded after installing windows 10

This one worked for me. I use an Hp envy, 64x

STEPS:
1) You have to update the AMD driver on the device manager. Go to settings / control panel -> device manager -> display adapters -> AMD (right click on it and choose update driver) 2) Then, once AMD driver is updated, it will disable the PnP. 3) enable PnP

Worked for me also. Not sure when it not-enabled. Whoever found this, thank you very much!

Configuration - HP Pavilion dv7 laptop. AMD Radeon. Windows 10

Symptoms

  • Monitor very dim, maybe 50%
    The function keys that typically adjust brightness no longer worked
    Normally, when I right-click on the battery icon, one of the options is "Adjust Brightness". That disappeared.
    In the power settings the ability to adjust brightness diappeared

Hansku got me on the right track.
In my case it was also the "monitor driver". It was showing "monitor" whilst it should be "generic PnP monitor"

1. Open device management
2. "show hidden devices"
3. Uninstall every device under monitors, select "delete driver" when possible
4. Rescan for hardware changes
5. Windows should atomatically install "generic PnP monitor"

fixed.

I don't know who any of you are...but thank you for this fix. I was so baffled by the inability to adjust the brightness which seemed to be permanently set to tan and bake.

Thank you, thank you, THANK YOU!!!!!!!!!!!!!!

Thank you! Device manager -> screens -> double click your screen (for me it said "genertic PnP screen)-> activate, for any other people looking for a solution and didn't understand the picture.
