Daisy chaining three (1440p) monitors (2x 16:9 and 1 21:9)

[Madzina]

Hi,

I just wanna ask if any of you have done similar daisy chaining connection:

Currently I have one Samsung s34j55x (21:9 1440p) display
I wanna buy two additional 1440p 16:9 displays with usb-c (like Dell P2720DC or LS27A600UUUXEN)
All of them are max 75Hz, and using yours calculator: total bandwidth of displayport 1.2 wont be enough, it will require at least displayport 1.3.
Unfortunately the spec of both of the displays says that they support displayport 1.2.
These displays are quite new and I really dont believe that displayport 1.2 is their max version.

The second question is: will usb-c port of my Dell Latitude 5480 be able to push displayport 1.3+ signal to any of those 2 monitors? Its displayport capable port but also version 1.2 according to spec.

Have any of you had any experience in similar setup?
