I have been wondering about the capabilities of Apple's $79 USB-C digital dongle. Apple's product page describes its intended use case like following: What I am wondering about if this is the only supported use of this dongle, or if other scenarios possible.. For instance - feeding power to MacBook via USB Type-A port (via Type-A to Type-C cable), and using USB-C port to connect to a monitor via DisplayPort Cable. Basically, I don't care about HDMI port - I want to connect MacBook to 1440p (or maybe even 4K) display, while charging it at the same time. If this dongle is a proper USB-C dock supporting DisplayPort Alt Mode - that should be possible.. and will in fact make it not such a bad purchase.. I am hoping this is why Apple is pricing it at $79, as it's a lot more than just a dumb adapter cable. I suspect no one truly knows yet, but can't help but wonder..
