Has anyone managed to get a display signal to go from the MacBook to the monitor via just a USB-C cable hooked up to the Dell displays? I bought a monitor on eBay without the original cables; I initially tried (which I figured wouldn't work) the original MacBook cable, then I ordered what I thought I needed from eBay and waited a week (USB 3 cable) and then I ordered another cable and waited a week (USB 3.1 cable). I'm starting to think either the dell cables are magic or this monitor just does not work with Apple things because I also tried my iPad Pro and it didn't do anything either. The 3.1 cable will charge it and if I connect other USB stuff to the monitor it can see it, but no video whatsoever. So basically, has anyone gotten any kind of display signal to come out of the rMB with a USB-C Dell monitor?
