I have been facing this issue. If anybody can help me??
I have got Acer USB type-c Dock II docking station. It has got two hdmi Port in it. If I connect windows OS laptop to acer dock using host cable and connect extra monitor to port 1 hdmi then it will detect extra monitor but if I disconnect a host cable usb type c and connect to MAC os laptop then it does not detect monitor. Similarly, if i connect hdmi port to port number 2 which is connected to Apple laptops then it detect extra monitor but can't detect monitor when connected to windows laptop again with port 2 HDMI port present in docking station.
