I will investigate / test and get back to you.
In the meantime, do you know why my Mac Mini wakes up when the receiver is turned on?
I turn on my receiver, AV processor and TV to watch television and my Mac Mini wakes up from sleep.
Is "wake on HDMI" active with with the Nvidia card / drivers (it detects that the receiver turns on and tells the Mac Mini to turn on)?
If so, is there any way to turn it off (it's rather annoying)?
