I have tried everything, going to advanced power settings, system settings but nothing. I have also tried to go to Intel options but i don't see any option to turn off power saving so I don't know what to do. It changes when im swapping windows, for example, if I am on Facebook and I swap to a game window, it decreases in brightness.
This was bugging me for years till I found answer in some obscure forum, here it the problem: https://support.microsoft.com/en-us/help/3046889/intel-display-power-saving-technology-settings-incorrect-if-power-source-changed-during-sleep
In case the link drops dead, here is still solution how to fix it
Open your Intel HD
- The drivers for your integrated Intel HD graphics card. I am aware this is counter intuitive for users who have dedicated graphics card, but the way this whole thing at point of writing is working means that most settings from here are considered 'master' settings.
Make sure that under
batteryyou have the power saving option disabled.
- Yes, I know that you might be thinking what kind of hard liquor I was drinking, but trust me, this setting is still in affect when you plug in your laptop into the wall.
- Make sure to check this from time to time, because I found out that this options get reactivated on updates and some other random triggers.
If you notice that your screen is still flickering brightens based on background, just unplug the power cable and plug it back it. This will reset some DPST settings and it will stop doing it. This happens only if you use sleep on your laptop. Full shutdown should be fine
The other answers didn't work for me - here's how I fixed it:
- From your desktop, click the Intel Graphics Settings icon in the bottom right-hand corner.
- Then from the Intel Graphics Settings dashboard, click on the Power icon.
- Tick Disable under Display Power Saving Technology.
This is taken from the Reddit source.
Late in the day, but I've just been entertained by this problem. After reviewing quite a few posts, none of which fixed the issue for me, I noticed that -
- Right click on desktop, select Graphics Properties
- Select Display
- Changed Refresh Rate from 40hz to 60hz and Saved the profile
Fixed the issue with Windows 10 contrast issue instantly for me on a Dell M4700 Precision.
Hope this helps folks.
For Windows Surface users
For those who don't have Intel® Graphics Command Center OR
Adaptative brightness in Power Manager, you can download Intel® Graphics Command Center from Microsoft Store (just write Intel Graphics Command).
Open Intel CMD Center you downloaded from MS Store, go to
System menu (left panel), then
Power and turn off:
- Adaptative brightness
- Display Power Saving
- Enhanced Power Saving
I found out that if you download/already have Intel Graphics Command Centre, you can go into 'System' then from there go into 'power'. And if 'adaptive brightness' is on, turn it off, however, for me it was already turned off, so go down and turn:
- display power savings: off
Now you shouldn't have that issue where your screen will automatically change brightness when it goes from dark to light images.
