I have been using Linux-to-Linux; multiple monitors work without problems, with respect to docking to edges etc. I use it as a a graphical terminal when I work from home, i.e. I sit in front of my machine at home, but everything happens on the machine at work. Laptop screen with 1440x900 resolution does not feel sluggish on effectively 40 Mbps wireless network, desktop screen with 3840x2160 works fine over 75 Mbps residential broadband. I can have voice chats over that link too. Electron apps are redraw hogs though; they feel a little bit sluggish at 4K. I would rather use 2560x1440 then. Emacs is fine in either.
