1. Should the screen be blank if my computer is asleep? Or is this a something I need to set? If there is a setting, I probably set it so long ago that I have forgotten where the setting is.

2. (If the screen is set to be blank when computer is asleep) How long should it take to go blank rather than the Date and time default?

I am asking because of a computer issue not related to the Squeezebox and LMS that seems easiest to diagnose by viewing the Squeezebox screen. Something in my set up of peripherlas seems to be preventing my Mac from sleeping even when I ask it to. Since the monitor does go dark, the only way I can easily tell if the computer is actually asleep or not is to check whether the Squeezebox screen is dark.
