Aside from my justified negative opinions about caldigit, i was referring to docks that offer 3+ (simultaneous) screen outputs (eg not one with 2 hdmi+2dp that can use either set but not all 4 together).
What you actually have to use is two thunderbolt ports on the MacBook. Then you can power not just two but four 6K screens, as each TB port can push 2 externals (in addition to built-in screen).
So this iVANKY dock is native TB quad screen, for example:
Im sorry, despite their marketing, this is a 2 output dock. Offering TB passthrough doesnt count, just like we wouldnt call regular usb hubs "multiple display docks" if some manufacturer came out with usb screens (whih im sure exist already for lowres output).
Still incorrect.
