@Blake_ASUS Hi, if you can help me here...

Hi GopalB,

May I have a screenshot of the option you are talking about?

Thank you.

@Blake_ASUS attaching the same for your reference.

you must add registry key , then only it will appear adaptive brightness under display

i am using asus laptop

Can you guide me how to do that ? @RAJU.MSC.MATHEMATICS @Blake_ASUS

You must have installed compatible intel graphics driver ,

follow three methods from below

or

or

type the following commands in cmd with admin rights and enter

powercfg -setdcvalueindex SCHEME_CURRENT 7516b95f-f776-4464-8c53-06167f40cc99 FBD9AA66-9553-4097-BA44-ED6E9D65EAB8 1

powercfg -setacvalueindex SCHEME_CURRENT 7516b95f-f776-4464-8c53-06167f40cc99 FBD9AA66-9553-4097-BA44-ED6E9D65EAB8 1

powercfg -SetActive SCHEME_CURRENT

reboot windows .

I am having AMD Vega 8 Graphics, which of the above method you think will work on that ? Also, processor is AMR Ryzen 5-3500U... Thanks, more help needed....@RAJU.MSC.MATHEMATICS

third method by doing commands

Any tutorial video for that? Feeling bit risky doing in command prompt directly.. Thanks. @RAJU.MSC.MATHEMATICS

commands are not risk.

nothing will happen, I have much experienced

So after this command method i will be able to see adaptive brightness under display in advanced power settings? Or it will just turn that off permanently? @RAJU.MSC.MATHEMATICS

first try it

Tried giving below attached "invalid parameter" error

@RAJU.MSC.MATHEMATICS

I given three commands. enter one by one

powercfg -setdcvalueindex SCHEME_CURRENT 7516b95f-f776-4464-8c53-06167f40cc99 FBD9AA66-9553-4097-BA44-ED6E9D65EAB8 1

powercfg -setacvalueindex SCHEME_CURRENT 7516b95f-f776-4464-8c53-06167f40cc99 FBD9AA66-9553-4097-BA44-ED6E9D65EAB8 1

powercfg -SetActive SCHEME_CURRENT

Ok entered one by one? Need to save this or will now close and restart? @RAJU.MSC.MATHEMATICS

once get successful then you must restart the windows

Did restart, still the same.. attaching for your reference...
