It is the year 2017, and as far as I know there is no computer OS that can handle multiple monitors really well, including sometimes just utterly losing video. New macbook pro usb c touchstrip latest mac os x flails in various annoying ways. Relatively recent Ubuntu 16.04 often freaks out wrt multiple monitors, and even goes blank after re-plugging in a video cable. I haven't touched a windows box in a long time, and nothing much newer than Win 7, so I dunno there, but I'd guess there are fubar things about that experience as well.
