Windows 10: dimmed... cannot fix

I adjusted the brightness with the F3 key days ago and now it wont go back. I went into settings and adjusted the brightness on the scale and still...nothing.

Programs not working


In post 26 there were steps listed to fix the operating system corruption.
Are you able to follow them?

display dimming

Hi,

There's a possibility that this issue is due to the Display settings of your device. For us to isolate your concern, we'd like to ask a few questions:

• Is it only happening when you connect your device to Windows 10?
• If it's not connected, have you noticed certain activities wherein the screen dims automatically?
• Have you tried using a different HDMI cable?
• What troubleshooting steps have you tried so far?

We hope to hear from you soon.

 

Adaptive Dimming

Thank you for providing your answer to the questions.

If that did not resolve your concern, follow the steps below:

• Go back to the first setting that you've tried (Refer to your screenshot).
• Under Dimmed display brightness, change the value of
  On battery and Plugged in option to "0".
• Click Apply and restart your computer.

Changing the value to "0" won't automatically reduce the display brightness of your computer.

Let us know how it goes.

Thanks.
