In a dual display setup...

(1) what should Windows do when you unplug one of the displays? For example, when you disconnect the HDMI cable?

(2) What should Windows do when you plug it back in?

(3) What should Windows do when you unplug BOTH displays?

(4) What what should Windows do when you plug both back in?

I'm asking in case the behavior I'm seeing is abnormal.
