Computer waking up from Sleep when I turn on monitor

Hi, my new pc does a strange thing, at least I find it strange because it's new: when the pc is on standby and I turn on the monitor, the pc wakes up.

Now I don't mind this behavior, it is useful even, but I was wondering if it is documented somewhere because I had no idea this was possible and I hope there's no strange electric contact or whatever.

The monitor also has a usb hub, but none of the devices connected to it are enabled to wake up the pc...

Sounds like an either or thing. Take your pick which it is waking up the computer, the monitor or the USB hub. Don't forget that there is a signal going both ways on those connections and it is likely one of them that is waking it up (my vote goes to the USB hub).

Yeah, I think it's the hub too. I disconnected it and the pc didn't wake up when turning on the monitor. I guess some setting somewhere is telling it to wake up on some kind of usb event.
