U2715H, daisy chain from both DP and mDP?
Hello all,
My personal PC is connected to the U2715H full size DP port. My work laptop is connected to the U2715H mDP port. I have also connected the MST full size DP port to another monitor's full size DP port. I can daisy chain from my personal PC but I cannot from the the work laptop. Does MST daisy chain not work with the mini DP port on the U2715H?
Thanks,
Steve

The online U2715H User's Guide page 25 only shows the 1st configuration =
Desktop DP out --> retail DP to DP cable --> U2715H #5 DP in (Menu- Display- DP 1.2 Enable)
U2715H #7 DP out --> retail DP to DP cable --> unknown monitor DP in
But, the U2715H shipped with the mDP to DP cable so in theory this should also work if the Laptop mDP is rated at 1.2 =
Laptop mDP --> U2715H mDP to DP cable --> U2715H #6 mDP in (Menu- Display- DP 1.2 Enable)
U2715H #7 DP out --> retail DP to DP cable --> unknown monitor DP in

Its weird...when my work laptop fires up the video I can see that the second monitor wants to display but then it goes blank and into power save.
Are there any issues with using a USB C(Thunderbolt 3) to miniDP for the primary monitor?

Unknown, we have never tested USB-C (Thunderbolt 3) to mDP usage in daisy chain.

better off having a monitor with E at the end of the model number, to do what you want.
e.g. P2722HE
