Windows multi-display functionality has regressed with packet based display protocols. Turning Display Port monitors off with their power button is a nightmare. All of your windows get squished down to so tiny size and moved over to one monitor. They won't fix it, because they consider it a power user use case that should be solved by leaving everything on or turning the entire computer off. There is an entire after market of hardware hacks built just to trick Windows into thinking the monitor is still connected.
