I have a refurbished 15" MPB with touchbar that I got in April. I have only been using it as a laptop until this weekend when my wife Brough home two Acer 27" monitors from work. I bought two USB-C to DVI cables to plug the monitors in & they work like a champ. I the plugged in power into the front left USB-C port & it would cut in & out. I moved it to the back port & it worked fine. I then tried to plug in my USB hub to the same port & it would not work. With nothing else plugged in, that port has worked fine for power, USB sticks, etc. But it seems that when I have two monitors plugged in the right side ports and power in the back left port, the front left port goes to crap. As a test case, I just unplugged the power, left the monitors plugged in on the right side, and the lower left port still appears to be dead. I know that the easy answer is to bring it to the Apple Store to have them look at it, but before I do that, I wanted to see if anyone else has had issues with the ports not working when you have other things plugged into all of them.
