I had that on one client machine with Windows 7. Download the newest video driver for your machine and install that. Reinstall the current driver if it is the newest.
If the computer vendor has power management software, upgrade or reinstall that.
Finally run System File Checker. Open cmd.exe with Run as Administrator and run SFC /SCANNOW twice. Close out, shut down, start up and test.

you can also test if changing the energy setting makes a difference
set it to never power off
I have asked several times - Have you updated / reinstalled the video driver?
If none of this works, you may need to do a Windows 7 Repair Install with the Windows 7 DVD (select the Repair option).

I have updated the video driver, not reinstalled the video driver.
Also, kindly look at the note I have in my initial request. This is for a machine running Windows 10, 64bit.

Sorry about the Windows 7 Note.
Try reinstalling the video driver and restart. Also try DISM (repair tool)
Open cmd.exe with Run as Administrator.
DISM.exe /Online /Cleanup-Image /Scanhealth (takes 15 - 20 minutes).
DISM.exe /Online /Cleanup-Image /Restorehealth (takes 15 - 20 minutes).
Restart the computer and test.
Not only windows itself has adaptive brightness settings, also the graphics driver software (by intel/nvidia/AMD/...) might have these settings. Please look through their settings, too.

Still dimming, all started happening after usinf windows 10
John
all started happening after using windows 10 <-- And on different monitors (so you said) as well. So that means the Video Driver is likely not Windows 10 compliant.
We cannot go through the settings for you and need your feedback if you did it thoroughly. I would expect this to be a setting inside the graphics control application. AMD has this in catalyst control center and I am pretty sure intel and nvidia will have these options, too.
I see no reason to think it's a non-compliant driver.
John
I have Intel Graphics and I do not see any setting to dim my monitor, and it does not dim either on its own.

That's fine, John - but what about his system?
Looking at mine (intel graphics, too), there is no adaptive brightness, but some adaptive contrast setting at least , see the screenshot. So it might be the model/driver combination that has or hasn't got it (do we know the brand of the video card yet, 100 questions? I don't see it).
There is a contrast enhancement on the Graphics Control panel, but not an Adaptive Contrast enhancement or Adaptive Brightness enhancement.
McKnife
Then we cannot help you. If it were broken, it would not be like this, for sure. There's some dimming component involved. Ask the manufacturers of
1 the monitor
2 the video card
where to find it. You could also compare to a different installation, of course.
