Mojave - OS X 10.14.4 & DisplayLink 5.1 - Mirrors - BUT NO EXTEND

So, this is interesting. I remembered that I'd installed Duet Display so that I could use my iPad as a second monitor last fall. For laughs, I uninstalled the Duet Display drivers *and* the DisplayLink drivers, disconnected the DisplayLink adaptor, restarted, then re-installed DisplayLink 5.1.1 drivers. Restarted again, plugged in the DisplayLink monitor, and...

Lo and behold, the DisplayLink monitor works correctly now! Not sure if this is a "just me" fix (the sequence of steps/troubleshooting only applies to my situation) or if this is something that might apply to others. Also, I haven't extensively tested it (i.e., haven't unplugged the monitor and plugged it back in, rebooted the laptop, etc.) but it appears there may be hope.

I'm using a Diamond Multimedia USB3 to DisplayPort adaptor with a DisplayLink DL-5500 chipset in it.
