Windows 8.1/10 – Fix Brightness Changes with Intel HD Graphics

brightnessintel graphicslaptopwindows 10windows 8.1

The brightness changes with the colors displayed on the screen on my Lenovo Thinkpads with Intel HD Graphics. Light colors make the screen brighter, dark make it darker. Same behavior in Windows 8.1 and 10.

The "adaptive brightness" feature in Windows is disabled.

Best Answer

Just found a suggestion that solved my problem here.

It is the Intel "Display Power Saving Technology" that is to blame.

Disable it like so:

Launch "Intel HD Graphics Control Panel" by right clicking and selecting "Graphics Properties..." from your Intel HD Graphics tray icon
Click Power
Choose "On battery"
Select "Disable" for Display Power Saving Technology
Click Apply

Try rolling back the display driver to the previous version.

Control Panel
  > Device Manager (opens a window) 
    > Display Adaptors 
      > Intel(R) HD Graphics 4400 (double-click) 
        > Driver (tab) 
          > Roll Back Driver.

It worked for me.

Changing power plan settings did not work, you need to type ''run'' then type ''services.msc''

Search in the list for ''sensor monitoring service'' right click on it, properties and disable the service, hit apply.

Navigate to HKEY_LOCAL_MACHINE\Software\Intel\Display\igfxcui\profiles\media\Brighten Movie and change ProcAmpBrightness to 0

also navigate to HKEY_LOCAL_MACHINE\Software\Intel\Display\igfxcui\profiles\media\Darken Movie and change ProcAmpBrightness to 0

Restart.
