As far as I can find, it's not a Windows 11 setting. It's probably proprietary to your laptop PC.

A quick online search gives no help with the Asus settings.

Something to try

Open Settings
Press Windows + I to open the Settings app.
Go to Display Settings
Navigate to:
System → Display
Scroll to Brightness & Color
You’ll see a "Brightness" slider.
Expand Advanced Brightness Settings
Below the brightness slider (or in some cases a link like “Brightness settings”), look for:
- “Change brightness automatically when lighting changes”
- “Help improve battery by optimizing content shown and brightness”
  (This is the Content Adaptive Brightness Control or CABC setting)
Turn both OFF

I rarely use my cheap Lenovo laptop.

I checked it. It has a slider for display brightness, but none of the Advanced stuff, as far as I could spot.

Thats a shame, thanks. It was the only answer I could find.

Is there any ASUS software, at all, on the laptop?

Have you meticulously gone through your “Power Options” properly? Check both “Settings” & via “Control Panel as per this Tutorial.

Depending on how it has been implemented with a given Laptop.

Laptop manufacturers may put several Power Plans in the Power Options.

Control Panel > Power Options > Change plan settings > Change advanced power settings > look thru all the branches in there for graphics settings.
The 3 choices on mine (Intel) are - Max battery life, Balanced, Max performance.
Select > Apply > OK.
The first of those selections may lower brightness which does lower power consumption.

Also look in the AMD integrated GPU control panel, I presume there is one.

They appear in Windows 11 settings, but slightly different wording.
System > Power > Power & battery > Power mode.

Just to make things easier for the for any future needs: clicking on the battery or speaker icon in the taskbar let you modify the brightness settings of your screen.

Thanks.

But I can't help but wonder whether there was a more direct way.
