I have a lovely new MacBook Pro (15"/2017) at work. It's running a StarTech TB3 dual monitor adapter. My two monitors (Dells) have worked fine for years off my dock.

After hooking up the MBP and adapter, the left monitor is on the right - and vice versa. I've gone into System Prefs > Displays and arranged them, but it doesn't do anything. (I can put either one above or below the other and it recognizes that).

I've also swapped the video cables around both on the adapter and monitors themselves. I can't get the left monitor to show the dock, and I have to move my mouse pointer off the left side of the left monitor to get it to the right monitor.

What am I missing here?
