Triple Head To Go DP issue

Doing my first show with 3 projectors running off of Qlab4, going through a Matrox Triple Head to Go DP.

I'm not seeing a consistant startup where my Mac sees the projectors. What is the right boot up order:

1) Projectors On.
2) Mac Boot

or

1.) Mac Boot
2) Projectors on.

In the past I've always fired up projectors first, and then booted the Mac.

By plugging and inplugging the Matrox either from the DP or USB for power it eventurally detects. What gives?

Clues for the clueless please!
 
Do you have the proper drivers installed. That makes a difference.
 
I updated firmware and everything worked for a second. We had to power down the active balun's for a moment, and then all of the signal was gone again. It looks like if I do a direct connection from each projector to the mac, and then plug in the Matrox it works. I need to verify in the AM.
 
On my MacBook Pro, running 10.12, I needed to fire up all projectors in advance. Let the Mac fully boot, and Matrox Software load, then connect the Triple Head 2 Go for it to detect properly. That solved the issue. Consistent detection every time now.
