A:AnswerNot sure how it will work without internet unless you plan to use your phone as a hotspot.I bought a USB cable to help extend the wifi signal. Since the chromecast plugs into the back, it seemed as though the tv was blocking the wifi signal.
A:AnswerShould work as long as the docking station has HDMI output. Whether or not it can support two monitors, I don't know.
Personal suggestion - I've worked with large monitors and multi-monitor setups before. If this is your first time with multi-monitors, be aware that you can't have this thing right in front of your face, and that it's going to take up a lot of real estate on your computer table surface. I like having dual monitors, I would not want two of these. I'm not sure I'd want one! Love it as a tv, but for my computer needs (sysadmin, DBA, developer, photo/video editing), I don't think I would want this one for that - too big. If I were setting up a server monitor display that I could watch the status of my network from across the room - yes. But not on my workstation.
