I just got my new MacBook Pro with Touchbar. Maxed out, souped-up. It is replacing my 2012 Retina MacBook Pro. My old set up was to connect 2 Dell monitors (a Dell U2715H and a slightly older one) to the MacBook using 1 connection through an OWC Thunderbolt hub (display port connection) and the other straight into the MacBook Thunderbolt port with a Displayport cable. No issues, worked flawlessly. With this new machine, I bought 2 Thunderbolt 3 (USB-C) to Thunderbolt 2 adapters, so that I could connect the monitors. Nothing is working well. With the Dell U2715H, the computer will expand the desktop as if the monitor is there, but the monitor will not sense a signal and will remain black. If I turn everything on and off 5 or 6 times, eventually it will show the image. With the other monitor, it will work only if I connect it through the OWC hub. So the adapters were expensive and were bough solely to support my ability to use the 2 monitors, and they are not working. Apple's Thunderbolt 3 (USB-C) to Thunderbolt 2 adapter will NOT support a Displayport connection to a monitor, unless (weirdly) it is run through a hub like the OWN Thunderbolt 2 hub. And even then, you may have to turn everything on and off multiple time to get the screen to show. This laptop cost a lot of money and I need it for productivity. External monitor support via Displayport should be something that works rock solid out of the box. Anyone else out there figured out a fix for this?
