Is it possible to Daisy Chain two Dell u2715h monitors connected to a MacBook Pro 2017?
So the setup would be USB-C to DP cable from the MacBook to first monitor and then the first monitor connected to the second monitor - known as Daisy Chaining.

I tested the exact setup on a MacBook Pro 2017 with Sierra and, after an update, also High Sierra.
It did not work. The two monitors will mirror each other and not extend the display.
I don't know why it does not work - Apple says, that the following MacBook Pro's support MST (Multi-Stream-Transport). Taken from this official apple documentation
I have read other places that other users have the same problem. I am guessing it is a software/driver problem as it works with a windows pc and other users have reported that it works on a mac running windows.
Actually, the 2017 Macbook Pros when used in conjunction with the OWC Thunderbolt 3 dock worked for me. I connected two BenQ monitors with that dock and got the two monitors plus the MBPs screen to come up as separate entities. No work required. Used a Display Port to Thunderbolt (USB-c) cable and a Display Port to mini-Display Port cable. The thunderbolt connector and mini-DP connector were both plugged into the Thunderbolt 3 dock and the dock was plugged into one port on the MBP.
