Brightness setting not working on Windows 11

[Glazgo]

The problem is that my display doesn't react to brightness changes in any way, neither os settings nor fn+f2/f3.
I have HP Support Assistant and everything is up to date.
Is it a problem with my computer or with drivers? Is there any solution?

@Ub6424 unfortunately, it didn't help.

Since on HP site there is no option with drivers for this notebook with windows 11,
I moved to windows 10 but the problem is still actual and nothing from Google didn't help too

Hello @Glazgo 

Are you running windows 10 now?

[Glazgo]

@Ub6424 Right, I decided that if there are no drivers for win11, with win10 should work, but it doesn't

Hello @Glazgo 

Did you follow the instructions from here again ?

[Glazgo]

@Ub6424 Yes, didn't help 😞
Weird but third-party software works in that case
