Unwanted automatic dimming of display on MacBook Pro (15-inch, 2019)

My screen is automatically dimmed by 15-20% every time the computer either wakes from sleep or returns from a lock screen after a few minutes of inactivity.

I have Catalina 10.15.5.

"Automatically adjust brightness" is not selected, as you can see below.

I have tried resetting the SMC the two ways recommended, and I've tried also resetting NVRAM/PRAM to no avail.

It is very frustrating to have to return to the brightness menu constantly to set it to a level which makes the laptop usable.

Any solution for that?

Look for a setting in Energy Saver for automatically dimming the screen after a period of time. Mostly used to save power when using battery power.

I'll give it a try, thank you!
