2016 Retina MacBook Pro Caveats
We bought a 15" 2016 Macbook Pro ("Retina" is redundant; there are no 2016 MBPs that lack a Retina display.)  We also bought a LG 27UD88-W monitor to go with it.  (It's one of the few that has a USB-C input.)I have to say, I'm really impressed by the single-cable solution.  The monitor charges the laptop (57W maximum, which is less than the Apple charger, but "good enough"), and the laptop sends both video and USB peripheral connections to the monitor, which acts as a USB 3.0 hub.One cable.  It's kind of amazing and magical if you think about it.There are some rough edges, though:(1) Sometimes the computer reports that it's not charging.  Sometimes it does.  We don't know why just yet.  We can always connect the Apple-supplied charger though.(2) When the display goes to sleep, it disconnects all the devices on the hub.  This is a problem for external disks, as the OS complains that it has been detached without being ejected first.  I hope LG fixes this in a future firmware version.(3) We can't use the Apple-supplied USB charging cable to connect the laptop to the display.  The connectors are the same, but.. it just doesn't work.  As a technical person, I understand why; but it's going to be unnecessarily confusing to people if two cables that look alike don't act alike.  This is going to raise technical support costs greatly until all USB-C cables are capable of all transports and functions and the old ones are phased out.  Why Apple didn't ship a fully-capable cable in the box is puzzling to me.
