True. Even Windows 7 and 8 allowed for dual screens; I imagine it'd be simpler in Windows 10 to just define the second screen as a new device (and doubtless harder in 11 - I don't like the way it does some things, or that there are one or two things it can't do, whereas earlier versions could). Back in '16 my manager used two screens routinely; I think it was possible to do what they did in Avatar, i.e. pass data from one device to another. I think.
