Yeah, its a new update from Nvidia drivers.

you can turn it off under brightness settings where you manually change options under the current power management you currently have (balanced, maximum performance etc)


Click on the battery icon. then Go to > adjust screen brightness > select the power management you want then right below it you will see change plan settings, click that then scroll down and click on display, it will expand few more options.

disable the "Adaptive Brightness" on your desire current settings (plugged in or battery)

Usually, it should only be on during battery saving mode. when under maximum power performance, it should be disabled. I case in your case which power management do you use when doing the work ? and are you using power4gear ?

Adaptive brightness uses an ambient light sensor (typically per the webcam) to adjust the backlight brightness, relative to the amount of light hitting the screen. That's not an NVidia proprietary feature to my knowledge (it's adjusted within Windows Power Options).

OP's description sounds more like dynamic contrast ratio, which I think is adjusted via the Intel HD graphics properties (if not, then it should be in the NVidia control panel).

X70xchallengerx, I have found using sticky dots on the front sensors works best.

Uh ambient brightness doesn't affect my display any, however I found a solution to my problem,

if you go into Nvidia Control Panel, go to "Adjust Video Color Settings", check "With Nvidia Settings:" and use full dynamic range, and disable "dynamic contrast enhancement." Restart computer and voila!! No more dimming on dark pages/programs!

How did the "Dynamic Contrast Enhancement" option get enabled?

My config was still set for "With the VIdeo player settings" - I think that was default - I don't recall playing with it on this laptop.

Just for grins I turned it on, yes it is annoying 🙂

But, now I will adjust the settings with Dynamic Range: Full without Dynamic Contrast Adjustment, thanks for the tip.

Thanks for the tips (use full dynamic range), now everything is fine! I've just noticed the same problem after I changed solid color as desktop wallpaper.

"... but, your Honor, we only turned on the Webcam and streamed it's output to our severs to gather anonymous use information, and assist in setting the screen brightness... Why yes, we did categorize the saved streams according to what we saw in the users home, we wanted to gather consumer interest information based on what we found in the users living and working environment... it was all anonymous - no names were attached to the collected data... why yes, GPS information was gathered and saved, so we knew the regional influence to help categorize the users interest for referral of local services and products... ah, yes, we did assign usernames to the saved streams, just not real names... at least at first... Yes, your honor, we understand where we went wrong, and we promise to never do it again... do what you ask? Why, never get caught again, of course...,And, yes the audio stream came with the video stream... Why didn't we filter out the audio stream and save space on our servers? Well your Honor, because the video isn't anywhere near as funny without the audio..."

JDVizart and others,

See this thread... It might not help you but we're trying to solve it and hopefully we will do it :rolleyes:
