The Mini Monitor should be working. I'm using it successfully on a MBP 2012 with TB 1 (!) and on my Hackintosh (both Win & OSX) with Apple's TB 3 to TB 2 Adapter, flawlessly.
I remember, I had some problems at first, too. Unfortunately I don't remember what solved this issue. Trying different versions of the Desktop Video app might help. Launching the Desktop Video app from the Control Panel never worked for me, by the way. It always crashed immediately. Launching it from the regular app folder did the trick.
Maybe this helps!?
