I connect my MacBook Pro with Thunderbolt 3 to a Lenovo C-Dock, which connects 2 external monitors through 2 DisplayPort cables. The problem I have is that the 2 external monitors mirror each other.
MacBook Pro (15-inch, 2018) macOS Mojave Version 10.14.3 (18D109) Lenovo USB-C Dock Type: 40A9
I looked at the display settings, and there is no options to change it. I also tried to connect one of the monitor through VGA port, the 2 monitors still duplicate.
How can I make the 2 external monitors display distinct content and not mirror each other?
