I have multi-computer setup with couple of Windows, a RaspberryPi 2, and a Mac. I use a Dell D6000 docking station which can connect computers on USB C and USB B 3. Unfortunately for my Pi2, I always have to connect over WiFi and use VNC. However when I play with its network interfaces, I have to connect it to one of my monitors on HDMI, and it may sound simple but folks with multiple computers on a standard sized desk can understand the pain.
I plan to upgrade to Pi4 and I understand that its USB Type C CANNOT be used for display as it is solely for power input, the question is, can its USB 3 port be used as video out?
