    Then there’s no way the non-pro models can use monitors, let alone 4k HDR. Pretty sure even if you power the monitor separately it just doesn’t transfer the data fast enough.

    I spent months trying to use a portable monitor with a USB-C 2.0 port until I found out there’s different versions and only 1 actually works for it.

      It can. USB C can support DP ALT mode where the pins effectively become DP pins in a USB C connector. I’m guessing data transfer is done via USB2 this and display is in DP ALT. Typically we’ve not seen this as anyone willing to put in ALT modes would want a fast interface too for data transfer, also knowing apple there is something proprietary going on.

      The main point is it’s not limited to USB Speeds. The pins can take on other functions. Even the pro does 10gbps USB where as 4k60 HDR in DP would be 14-20gbps far in excess of it’s USB bandwidth.
