While using desktop, screen will go black. Still can hear audio. If I press any key, the screen comes back. Is happening frequently now. Been happening for several months, but is increasing in occurrence. Running Monterey 12.7.6 (no longer updates), 4 GHZ Quad-core Intel i7, 16 GB Memory, 2T storage
iMac 27″, macOS 12.7

Computer Sleep and Display Sleep/Off are two different functions.
The computer will not sleep if you are running audio (ie Music or Streaming) in the background.
However the Display will Sleep/Turn off if you are not actively using the keyboard or mouse.
I went in and set the energy saver to prevent your mac and turn display off after 1 1/2 hr. Will see what happens. The default had it at 10 min., put hard disks to sleep when possible, wake tor network access, and enable power nap. However, it shouldn't go to sleep while I'm working on it and still have audio in the background, I wouldn't think.
