Adaptive Brightness - Turn On or Off in Windows 8

How to Turn On or Off Adaptive Brightness in Windows 8 and 8.1


information   Information
This will show you how to turn adaptive brightness on or off to have Windows 8 use a light sensor (usually built into the display) to automatically adjust the screen brightness to match the lighting conditions in your PC's surroundings.

To determine if your laptop or computer monitor supports adaptive brightness, look for the Enable adaptive brightness setting in Power Options in the steps below. If the Enable adaptive brightness setting is not available, then it doesn't support adaptive brightness.

This will affect all users on the computer that use the same power plan that you have this set for.





OPTION ONE

1. Open the Advanced Power Settings for your power plan.​
2. Expand Display and Enable display brightness, then set adaptive brightness to be turned on or off for when your computer is On battery and Plugged in. (see screenshot below)​

OMG - this makes me look SO incredibly lame! WHY did I not research further, and find this great forum earlier? I am just (as my profile says) so darn impatient and I never read directions LOL - that needs to change!

ADAPTIVE BRIGHTNESS - DUH! I am again - VERY lame! After installing the Windows 8 Release Preview last week on my NEW Dell Inspiron Duo, I could not get the screen to stop dimming ALL of the time! So what did I do? I cracked the thing open, took it all apart, and I unplugged the light sensor cable from the motherboard! LOL LOL - again - I am LAME! I deserve the LAME hat!! LOL

If only I had found this sooner. Oh well - now I DEFINITELY have Adaptive Brightness OFF - and FOR GOOD! LOL

Hello Mike, and welcome to Eight Forums.

LOL, don't worry about it. We are all always learning. :)
 
........is a light sensor standard equipment these days on laptops?

or is that just another use of the inbuilt webcam?

Hello xraiderv1,

It varies, but most new laptops have this light sensor for adaptive brightness these days. :)

I wouldn't worry about it. Most people end up turning it off anyways due to it not adjusting the screen brightness properly or to their liking.
 
Well for some reason this didn't do the trick for (and I've been stuck with this, very frustrating feature for about a month now)

What did work however, was disabling the Sensor Monitoring Service.

Sorry to hear that Talmarsh. I added that option to the tutorial for those that have the same issue.

Thank you for posting back with your results. :)
 
Maybe it was just wishful thinking... and maybe this weird feature got the better of me.. But it seems yet to remain ON! Can't get rid of it :-\
I love win 8 but this is really annoying... It doesn't adjust the screen lighting (which would still be annoying), just the brightness parameters and makes everything look all washed out... :(
 
Hello Talmarsh,

Double check your other dim settings in Power Options to see if they may be set to dim the display after X amount of minutes.

If this is for a monitor, then it may have it's own separate built-in adaptive brightness settings.
 
Wow this is embarrassing!
Playing around with the services turned the Adaptive Brightness in both of my custom power plans (I'm positive it was switched to "off" state...)! in retrospect, I may have disabled/enabled the service a few times to check for differences.. Never thought to check inside the power plans again..

Hope this one lasts :)
Cheers!
