Windows 10: Win10 display auto-dimming/brightening

I'm on Lenovo Ideapad 510. Been using Win10 which came along with it for almost 1.5 years. From last 2 months, due to some update, selecting/opening an app, dims the display if the background is black. In 5 steps, the dimming changes to a drastic level. The opposite happens when a white background is selected. The stupidest thing, is that, for white it should be dimming and for black, it should be brightening, but microsoft is doing opposite. This is getting slightly harmful to eyes - why doesn't it leave it to the user like before? Very noticeable at night. Tried many things like turning OFF Night-light, updating display drivers, night-mode OFF etc etc. Still this is the same. Any idea, to stop this?

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.

 

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).

Thanks for your input.

I tried another monitor/tv and it did not dim/brighten randomly. So I will now focus on the hannespree.

Thank you again.
