Anyone who has found a working solution to power a macbook 12" and output 4k@60hz video simultaneously through the USB type-C connector? Outputting 4k@60hz works just fine for me (http://9to5mac.com/2016/06/04/how-to-enable-4k-60hz-resolution-2016-macbook/, using a USB type-C to displayport cable), but I have not found a solution that provides power as well. The hubs I have checked out either lack the ability to power the macbook, or limit video output to 30hz. To clarify, I don't want to buy a completely new display, because I have too many of those already. I am aware that there is one display that accepts a video signal through USB type-C and powers the macbook at the same time, but I am looking for a generic solution that works with other displays.
