2 UP2716D with PC and 7530

I am interested to buy two display UP2716D and connect it with DP MST daisy chain.

I would connect one PC with DP cable to the first UP2716D, and with daisy chain connect to second UP2716D.

I would also connect a Precision 7530 with mDP to the first display and with daisy chain connect to second UP2716D. So I can use a multi-monitor with two pc one at time with extended desktop.

My questions are:

Does Daisy chain work with mDP?

Is this connect solution correct? And if I switch  input on the first UP2716D, does second UP2716D switch automatically?

Thank you,

Stefano
