I'm not sure I understand. Why are we talking about interlaced video? 
That doesn't seem to be relevant unless I'm missing something.

There are plenty of 4k 120Hz and 144Hz monitors on the market right now.

I am currently only running dual 60Hz 4K monitors right now with an AMD 
RX580 GPU each connected via Display Port 1.2

I believe a single Displayport (version 1.3) can support 4K 120 or 
144Hz.

There may be some useful information at this link
https://en.wikipedia.org/wiki/DisplayPort#Resolution_and_refresh_frequency_limits

I regret that I don't know anything about MST or SST. Hopefully someone 
can help you more. I'm interested to learn what you figure out.
