Successfully connect and extend both of my Dell "U2517D" monitors using my "Hubee" usb-c dock to my MacBook Pro to render 3 separate windows(Mbp screen included).


The usb-c dock has a DP cable(connected to one of the dell monitors) and a HDMI cable(connected to one of the dell monitors) plugged into it picture, this allows both monitors to operate however they only seem to render a singular mirrored display output picture. In display preferences this is what I see picture. I have attempted to daisy chain both monitors together then doing a single DP connection to the dock but it didn't work. I have also tried pressing the detect monitors button in the display preferences but it has not worked.


What you ask is simply not possible with that hardware.

Due to the way the signal must be demultiplexed, you will need a Thunderbolt 3 dock instead of a USB-C dock to be able to drive the two external displays with separate content.

Alternatively you can connect one of the monitors directly to the MacBook Pro using a standard USB-C to DisplayPort cable.
