I have two 5K Ultra-fine displays, connected to 2016MBPro, 2.9 16GB,Radeon460 2TBSSD.
Top of the line everything.
I solved the monitor random disconnects by moving the wifi router 4 feet from the monitors - thanks for that suggestion.

I find it interesting that Apple does not support macOS Sierra on our old Mac Pro 3,1 and yet the virtual machines running El Capitan inside of it in Parallels can be upgraded to Sierra seemingly with no problem. Seems not too intuitive the lack of support.
I managed to add the latest Remix OS as a VM, but I am wondering if there is any possible way to install parallels tools in it. I know for some Linux distros that you have to mount the cd drive in the terminal, but I don't know if anything like that is possible with Remix. Any ideas?
