Windows 10: brighten screen

I am trying to brighten my screen but for some reason when I go to the display screen it doesn't give me the option to brighten my screen only to turn the nightlight on or off but even when I click on it nothing changes.

Screen dimming and brightening on its own.


My monitor seems to be dimming and brightening on its own. My system is a desktop with a monitor which is really a flatscreen tv.

Everytime I close out something the screen dims. When I open up something it brightens again but it may not stay bright. When doing MS Word it will dim and brighten as I do key strokes or scrolling.

Right now as I'm composing this thread, it is staying bright.

I just scrolled up to the top of the screen and it dimmed (looking for post button which I now see is below and not up).

 

After upgrade to Windows 10, screen keeps dimming, then brightening!

I have updated the Display adapters as per another answer, but the dim/brighten/dim/brighten issues seems to be persisting. Can anyone suggest another remedy please. My laptop is an HP Pavilion.

Unigine Valley or Heaven (use this for quick testing while changing settings in Wattman and checking for stability / artifacts) ...just suggesting this
How to monitor cores / mem speeds and temps during testing (I've seen screen overlays, and others using GPUz)
