I was reading about one a couple weeks back and forgot it's name. Really what I want one for is so that I can save default monitors for programs. IE: spotify always opens on monitor 2 and VLC on monitor 3.
How well do these work with a monitor that isn't always connected? Basically the third monitor is my TV that I have hooked up to the PC for movies. It doesn't always happen, but sometimes when I turn it on, all the windows move over to it. Kind of annoying, especially when I just turn the TV on to watch cable or play another console and have to win+shift everything back over.
Looks like my problem may be a Windows thing. DisplayFusion is working for monitor specific apps, but everytime I turn the TV on, it automatically makes it "Monitor 1", moving my main display to "Monitor 2", and the second display the "Monitor 3"
