If by current infrastructure you mean WiFi, then I agree.
However, I have been using a WiGig dock with 3 1080p displays attached for the past 6 months, and it has been trivial to set up, and nigh indistinguishable from a display connected over wires.
For the record, I used to play FPS games competitively, and I still find the input lag on many IPS monitors completely unbearable to this day. For my eyes, the WiGig dock adds no discernible input lag or compression artifacts to any of my 3 displays, except in games where some frame dropping can still be observed in exceptionally intense moments.
I honestly can't wait for the day when laptops with WiGig and Wireless Charging become mainstream.
